ios 项目总结二2
1 还是scrollview的使用，判断向左向后滑动的判断
-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{ newx=scrollView.contentOffset.x; if (xiaotu_array.count*650>newx) { if (newx != oldIx ) { //Left-YES,Right-NO if (newx > oldIx) { huaTag++; NSLog(@"右滑 ===%d",huaTag); }else if(newx < oldIx){ huaTag--; NSLog(@"左滑-- ===%d",huaTag); } oldIx = newx; } } }
当时判断左右滑动是有个方法，响应的Hugtag判断了，但是oldIx的位置总是滑动初始化显示的是上次的的位置，所以导致判断总是不正确，所以再点击按钮的时候重绘oldIx的位置为oldIx=0；
2 pagecontrol和UIscrollvew的结合实现，
pagecontrol = [[UIPageControl alloc]initWithFrame:CGRectMake(280, 680, 50, 23)];
pagecontrol.numberOfPages = xiaotu_array.count;
pagecontrol.currentPage = 0;
pagecontrol.pageIndicatorTintColor = [UIColor blackColor];
pagecontrol.currentPageIndicatorTintColor=[UIColor grayColor];
[viewRight addSubview:pagecontrol];
- (void)scrollViewDidScroll:(UIScrollView *)scrollview
{
根据scrollview的滑动判断page的位置
if (scrollview==Bigscroll) {
[seachView removeFromSuperview];
isShowSearch=YES;
int page = scrollview.contentOffset.x / 650;
pagecontrol.currentPage = page;
if (page < xiaotu_array.count) {
[pagecontrol setHidden:NO];
pagecontrol.currentPage=page;
[pagecontrol setNumberOfPages:xiaotu_array.count];
}else if(page >= xiaotu_array.count && page < streetImages.count+xiaotu_array.count)
{
[pagecontrol setHidden:NO];
pagecontrol.currentPage=page-xiaotu_array.count;
[pagecontrol setNumberOfPages:streetImages.count];
}else
{
pagecontrol.hidden = YES;
}
if (scrollview.contentOffset.x/650 < xiaotu_array.count && scrollview.contentOffset.x/650 >= 0) {
[mtt setImage:[UIImage imageNamed:@"dj-mtt.png"] forState:UIControlStateNormal];
[biaoshi_line setFrame:CGRectMake(60, 36, 73, 5)];
}
if (scrollview.contentOffset.x/650 >= xiaotu_array.count && scrollview.contentOffset.x/650 < xiaotu_array.count+streetImages.count) {
[jiePai setImage:[UIImage imageNamed:@"dj-jpt.png"] forState:UIControlStateNormal];
[biaoshi_line setFrame:CGRectMake(193, 36, 73, 5)];
}
if (scrollview.contentOffset.x/650 == xiaotu_array.count+streetImages.count) {
[dpt setImage:[UIImage imageNamed:@"dj-sjstj.png"] forState:UIControlStateNormal];
[biaoshi_line setFrame:CGRectMake(345, 36, 73, 5)];
}
if (scrollview.contentOffset.x/650==xiaotu_array.count+streetImages.count+1) {
[kccx setImage:[UIImage imageNamed:@"dj-kccx.png"] forState:UIControlStateNormal];
if (isDrag==YES) {
[self performSelector:@selector(loadKuCunData) withObject:nil afterDelay:0];
isDrag=NO;
}
}
}
}
3 九宫格的实现 ，可以实现删除的实现，在scrollview添加的button实现
//初始化scrollview [scroll removeFromSuperview]; scroll=[[UIScrollView alloc]initWithFrame:CGRectMake(90, 100, 1024-180, 768-170)]; scroll.backgroundColor=[UIColor whiteColor]; scroll.delegate=self; [self.view addSubview:scroll]; isShowBtn=NO; [self performSelector:@selector(initBtn) withObject:self afterDelay:0];
//初始化九宫格button -(void)initBtn{ int width = scroll.frame.size.width/4; for (int i=0; i<allArrys.count; i++) { t=i/4; int d=fmod(i, 4); UIView *nView = [[UIView alloc] initWithFrame:CGRectMake(width * d + 5+d*10, HIGHT * t +5+t*50, WIDTH, HIGHT)]; // NSLog(@"---%@",NSStringFromCGRect(nView.frame)); nView.backgroundColor=[UIColor whiteColor]; nView.tag=1000+i; UIImageView *BgImage=[[UIImageView alloc]init]; BgImage.frame=CGRectMake(0, 0, 145, 187); BgImage.backgroundColor=[UIColor clearColor]; BgImage.image=[UIImage imageNamed:@"bj.png"]; [nView addSubview:BgImage]; nView.backgroundColor=[UIColor whiteColor]; UIButton *appBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [appBtn setFrame:CGRectMake(2, 2, 141, 183)]; [appBtn addTarget:self action:@selector(goNext:) forControlEvents:UIControlEventTouchUpInside];//默认是走下一页 appBtn.tag = i; [nView addSubview:appBtn]; NSString *aaa=[[dicInfo objectForKey:[allArrys objectAtIndex:i]] objectForKey:@"danpin"]; // NSString *bbb=[NSString stringWithFormat:@"%@",aaa]; NSString *ss=[NSString stringWithFormat:@"Documents/styleSmall/x%@",aaa]; NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"%@",ss]]; NSString *fileName=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil]; NSString *imageNames=[fileName stringByReplacingOccurrencesOfString:@"-" withString:@"1"]; [appBtn setImage:[UIImage imageWithData:[DataPist stringToByte:imageNames]] forState:UIControlStateNormal]; NSLog(@"---%@",dicInfo); UILabel *label1=[[UILabel alloc]init]; label1.frame=CGRectMake(0,187, 200, 20); label1.text=[[dicInfo objectForKey:[allArrys objectAtIndex:i]]objectForKey:@"huoHao"]; label1.textColor=[UIColor grayColor]; label1.font=[UIFont systemFontOfSize:12]; [nView addSubview:label1]; UILabel *label2=[[UILabel alloc]init]; label2.frame=CGRectMake(0,187+20, 150, 20); label2.text=[[dicInfo objectForKey:[allArrys objectAtIndex:i]]objectForKey:@"chanPinName"]; label2.textColor=[UIColor grayColor]; label2.font=[UIFont systemFontOfSize:12]; [nView addSubview:label2]; UILabel *label3=[[UILabel alloc]init]; label3.frame=CGRectMake(0,187+40, 30, 20); label3.text=@"RMB"; label3.textColor=[UIColor grayColor]; label3.font=[UIFont systemFontOfSize:12]; [nView addSubview:label3]; UILabel *label4=[[UILabel alloc]init]; label4.frame=CGRectMake(40,187+40, 100, 20); NSString *price=[[dicInfo objectForKey:[allArrys objectAtIndex:i]]objectForKey:@"money"]; // label4.text=[price substringToIndex:price.length-5]; label4.text=price; label4.textColor=[UIColor grayColor]; label4.font=[UIFont systemFontOfSize:12]; [nView addSubview:label4]; UIImageView *tagImgView = [[UIImageView alloc] initWithFrame:CGRectMake(145-31, 1, 30, 30)]; [tagImgView setImage:[UIImage imageNamed:@"sc.png"]]; [tagImgView setHidden:YES]; [nView addSubview:tagImgView]; [scroll addSubview:nView]; // nView.userInteractionEnabled = YES; [scroll setContentSize:CGSizeMake( 1024-180,(t+1)*280+50)]; // NSLog(@"-=t=%d==--%@",t,NSStringFromCGRect(scroll.frame)); } UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(LongPressGestureRecognizer:)]; [scroll addGestureRecognizer:lpgr]; UITapGestureRecognizer *oneFinger=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(oneFinger:)]; oneFinger.numberOfTapsRequired = 1; oneFinger.delegate=self; [scroll addGestureRecognizer:oneFinger]; // [self performSelector:@selector(jisuan) withObject:nil afterDelay:1]; }
添加方法
//判断是否点击事件，如果长按就isShowBtn==YES，走删除，没按长按或者不按的话就是走另一个页面，isShowBtn==no； -(void)goNext:(UIButton *)sender{ if (isShowBtn==YES) { //走删除页面 UIButton *btn=(UIButton *)sender; [self btnTag:btn.tag]; }else if (isShowBtn==NO){ //走另一个页面 DanPin_ViewController *danPinVC=[[DanPin_ViewController alloc]init]; danPinVC.smallName=[[dicInfo objectForKey:[allArrys objectAtIndex:sender.tag]] objectForKey:@"huoHao"]; [self presentViewController:danPinVC animated:YES completion:NULL]; } } //删除 -(void)btnTag:(int )tag{ [self deleteAppBtn:tag]; } //删除实现 - (void)deleteAppBtn:(int)index { NSArray *views = scroll.subviews; // NSLog(@"----%@",views); __block CGRect newframe; for (int i = index; i < [allArrys count]; i++) { UIView *obj = [views objectAtIndex:i]; __block CGRect nextframe = obj.frame; if (i == index) { [obj removeFromSuperview]; } else { for (UIView *v in obj.subviews) { if ([v isMemberOfClass:[UIButton class]]) { v.tag = i - 1; break; } } [UIView animateWithDuration:0.6 animations:^ { obj.frame = newframe; } completion:^(BOOL finished) { }]; } newframe = nextframe; } if ([PlistName isEqualToString:@"dataOne"]) { [[SavePList sharedInstance]removeBookWithKey:[allArrys objectAtIndex:index] name:@"dataOne"]; [allArrys removeObjectAtIndex:index]; [self initZongJia:@"dataOne"]; }else if ([PlistName isEqualToString:@"dataTwo"]){ [[SavePList sharedInstance]removeBookWithKey:[allArrys objectAtIndex:index] name:@"dataTwo"]; [allArrys removeObjectAtIndex:index]; [self initZongJia:@"dataTwo"]; }else if ([PlistName isEqualToString:@"dataThree"]){ [[SavePList sharedInstance]removeBookWithKey:[allArrys objectAtIndex:index] name:@"dataThree"]; [allArrys removeObjectAtIndex:index]; [self initZongJia:@"dataThree"]; } [self endAnimation]; } //点击取消事件 -(void)oneFinger:(UIPanGestureRecognizer *)gr { [self setCancleFlag]; [self hideBtn]; } //长按删除事件 - (void)LongPressGestureRecognizer:(UIGestureRecognizer *)gr { isShowBtn=YES; if (gr.state == UIGestureRecognizerStateBegan) { if (m_bTransform) return; for (UIView *view in scroll.subviews) { view.userInteractionEnabled = YES; for (UIView *v in view.subviews) { if ([v isMemberOfClass:[UIImageView class]]) [v setHidden:NO]; } } m_bTransform = YES; [self BeginWobble]; } //判断师傅要全部删除 if ([ret isEqualToString:@"1"]) { guanZhuBtn1.hidden=YES; removeBtn1.hidden=NO; }else if ([ret isEqualToString:@"2"]){ guanZhuBtn2.hidden=YES; removeBtn2.hidden=NO; }else if ([ret isEqualToString:@"3"]){ guanZhuBtn3.hidden=YES; removeBtn3.hidden=NO; } }
-(void)BeginWobble { // NSAutoreleasePool* pool=[NSAutoreleasePool new]; for (UIView *view in scroll.subviews) { srand([[NSDate date] timeIntervalSince1970]); float rand=(float)random(); CFTimeInterval t=rand*0.0000000001; [UIView animateWithDuration:0.1 delay:t options:0 animations:^ { // view.transform=CGAffineTransformMakeRotation(-0.05); } completion:^(BOOL finished) { [UIView animateWithDuration:0.1 delay:0 options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse|UIViewAnimationOptionAllowUserInteraction animations:^ { // view.transform=CGAffineTransformMakeRotation(0.05); } completion:^(BOOL finished) {}]; }]; } // [pool release]; } -(void)EndWobble { // NSAutoreleasePool* pool=[NSAutoreleasePool new]; for (UIView *view in scroll.subviews) { [UIView animateWithDuration:0.1 delay:0 options:UIViewAnimationOptionAllowUserInteraction|UIViewAnimationOptionBeginFromCurrentState animations:^ { view.transform=CGAffineTransformIdentity; for (UIView *v in view.subviews) { if ([v isMemberOfClass:[UIImageView class]]) [v setHidden:YES]; } } completion:^(BOOL finished) {}]; } // [pool release]; } //设置取消设置delegte的image按钮 -(void)setCancleFlag{ isShowBtn=NO; if(m_bTransform==NO) return; for (UIView *view in scroll.subviews) { view.userInteractionEnabled = YES; for (UIView *v in view.subviews) { if ([v isMemberOfClass:[UIImageView class]]) [v setHidden:YES]; } } m_bTransform = NO; [self EndWobble]; }
5 ipad的实现popView实现，还有就是定制pop的颜色

break; } case UIPopoverArrowDirectionDown: { height -= arrowHeight; coordinate = ((CGRectGetWidth(self.frame) / 2.0) + arrowOffset) - (arrowBase / 2.0); arrowImageView.frame = CGRectMake(coordinate, height, arrowBase, arrowHeight);

用的时候直接调用就可以了，
UIViewController *viewControllerPick=[[UIViewController alloc]init];
popView=[[PCPopoverController alloc]initWithContentViewController:viewControllerPick andTintColor:[UIColor whiteColor]];
[popView setPopoverContentSize:CGSizeMake(200, 185) animated:YES];
popView.delegate=self;
一个页面多个popview的实现根据textfield的 tag 实现
-(void)textFieldDidBeginEditing:(UITextField *)textField{
CGRect rect=[self.view convertRect:textField.frame fromView:textField.superview];
[popView presentPopoverFromRect:rect inView:self.view permittedArrowDirections:
UIPopoverArrowDirectionLeft animated:YES];
}
popview里面添加tableview的实现多选单选，全选
实现全选按钮或取消全选按钮，设置bool值点击
allSelectFlag=YES;这块设置bool
for (int row=0; row<20; row++) {这块是显示可见的cell的点击按钮，所以为显示的cell无法全选，所以就需要设置bool值做判断，这样就可以全选了，
UITableViewCell *oneCell = (UITableViewCell *)[table cellForRowAtIndexPath:[NSIndexPath indexPathForRow:row inSection:0]];
oneCell.accessoryType = UITableViewCellAccessoryCheckmark;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell;
NSString *identity=[NSString stringWithFormat:@"%d%d",indexPath.section,indexPath.row];
cell=[tableView dequeueReusableCellWithIdentifier:identity];
if (cell==nil) {
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identity];
cell.selectionStyle=UITableViewCellSelectionStyleGray;
}
cell.textLabel.font=[UIFont systemFontOfSize:13];
cell.textLabel.textAlignment=NSTextAlignmentCenter;
cell.textLabel.text=[aryyYears objectAtIndex:indexPath.row];
if (allSelectFlag==YES) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
if (allSelectFlag==NO) {
cell.accessoryType = UITableViewCellAccessoryNone;
}
}
tableview的多选实现和单选实现
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *oneCell = [tableView cellForRowAtIndexPath: indexPath];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
UITextField *textField;
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if([typePick isEqualToString:@"0"]){
//多选
textField=(UITextField *)[self.view viewWithTag:1000];
if (oneCell.accessoryType == UITableViewCellAccessoryNone) {
oneCell.accessoryType = UITableViewCellAccessoryCheckmark;
NSString *aaa=[aryyYears objectAtIndex:indexPath.row];
//NSString 字符串的实现添加和删除某段字符串方法
[YearString appendString:[NSString stringWithFormat:@"%@,",[aaa substringToIndex:aaa.length-1]]];
[findString appendString:[NSString stringWithFormat:@"%@,",[aryyYears objectAtIndex:indexPath.row]]];
} else{
oneCell.accessoryType = UITableViewCellAccessoryNone;
NSString *aaa=[aryyYears objectAtIndex:indexPath.row];
[YearString deleteCharactersInRange:[YearString rangeOfString:[NSString stringWithFormat:@"%@,",[aaa substringToIndex:aaa.length-1]]]];
[findString deleteCharactersInRange:[findString rangeOfString:[NSString stringWithFormat:@"%@,",[aryyYears objectAtIndex:indexPath.row]]]];
}
textField.text=findString;
单选实现
// NSArray *arry=[tableView visibleCells];
for (UITableViewCell *cell in arry) {
[cell setAccessoryType:UITableViewCellAccessoryNone];
}
[[tableView cellForRowAtIndexPath:indexPath]setAccessoryType:UITableViewCellAccessoryCheckmark];
}
}
字符串实现追加字符串和根据多选实现的删除方法
1 appendString:字符串的追加
2 字符串的删除 ：deleteCharactersInRange:[findString rangeOfString：@"sdsds"]
3 字符串的截掉后面几位[aaa substringToIndex:aaa.length-1]
字符串还有很多操作方法，有待学习
以上目前就是想到的新项目中的问题，其实还有许多问题，没写出来，等有时间好好总结下，
