AutoHome项目的学习
1.自定义UITabBar
1 #import <UIKit/UIKit.h> 2 3 @interface XHQTabBarViewController : UITabBarController 4 @property(nonatomic,strong) NSMutableArray * controllers 5 ; 6 7 //@tip 创建tabbaritem 8 //@para title tabbaritem标题 9 // normal 正常情况下tabbaritem图片 10 // selectedImage 选中情况下tabbaritem图片 11 // controllerName tabbaritem所对应的的控制器 12 //@result 无 13 -(void) addItem:(NSString*)title normalImage:(UIImage*)normal highLightImage:(UIImage*)selectedImage controller:(NSString*)controllerName ;
1 #import "XHQTabBarViewController.h" 2 3 @interface XHQTabBarViewController () 4 5 @end 6 7 @implementation XHQTabBarViewController 8 9 //初始化 10 -(instancetype)init{ 11 if (self=[super init]) { 12 _controllers = [[NSMutableArray alloc] init]; 13 } 14 return self; 15 } 16 17 //创建tabbaritem 18 -(void) addItem:(NSString*)title normalImage:(UIImage*)normal highLightImage:(UIImage*)highLight controller:(NSString*)controllerName { 19 20 //创建tabBarItem 21 normal = [normal imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; 22 highLight = [highLight imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; 23 UITabBarItem * item = [[UITabBarItem alloc] initWithTitle:title image:normal selectedImage:highLight]; 24 [item setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor blackColor],NSFontAttributeName: [UIFont systemFontOfSize:15]} forState:UIControlStateNormal]; 25 26 //得到控制器类 27 Class controllerClass = NSClassFromString(controllerName); 28 29 //创建控制器 30 UIViewController * controller = [[controllerClass alloc] init]; 31 controller.navigationItem.title = title;//设置导航栏标题 32 33 //创建导航栏 34 UINavigationController * navigationController = [[UINavigationController alloc] initWithRootViewController:controller]; 35 36 //设置item 37 controller.tabBarItem = item; 38 // controller.tabBarController.tabBar.barTintColor = ; 39 self.tabBar.barTintColor =[UIColor colorWithRed:121.0/255 green:200.0/255 blue:231.0/255 alpha:1]; 40 41 //将控制器加入数组 42 [_controllers addObject:navigationController]; 43 44 } 45 @end
2.设置cell的动画:
//给cell添加动画
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
//设置Cell的动画效果为3D效果
//设置x和y的初始值为0.1；
cell.layer.transform = CATransform3DMakeScale(0.1, 0.1, 1);
//x和y的最终值为1
[UIView animateWithDuration:1 animations:^{
cell.layer.transform = CATransform3DMakeScale(1, 1, 1);
}];
}
3.表视图设置索引:
1 - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView 2 { 3 NSArray *array = @[@"A", @"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",@"M",@"N",@"O", @"P", @"Q", @"R", @"S", @"T", @"U", @"V", @"W", @"X", @"Y", @"Z"]; 4 self.tableView.sectionIndexBackgroundColor = [UIColor clearColor];//背景色 5 self.tableView.sectionIndexColor = [UIColor blueColor];//字体色 6 return array; 7 }
1 //索引点击事件 2 -(NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index { 3 4 NSLog(@"点击了第%ld个",index); 5 return 20; 6 }
4.UICollectionView的头尾视图设置:
1 #pragma mark 设置头尾视图的大小 2 3 - (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section 4 { 5 return CGSizeMake(XHQ_SCRWIDTH, 50); 6 }
1 #pragma mark 返回头尾视图 2 3 - (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath 4 { 5 UICollectionReusableView *reusableView = [collectionView dequeueReusableSupplementaryViewOfKind:kind withReuseIdentifier:@"HEADER" forIndexPath:indexPath]; 6 7 for(UIView *subview in reusableView.subviews) 8 { 9 [subview removeFromSuperview]; 10 } 11 12 13 UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, XHQ_SCRWIDTH, 50)]; 14 15 XHQFoundCarSubModel *model = self.dataSource[indexPath.section]; 16 17 label.text = model.name; 18 19 [reusableView addSubview:label]; 20 21 22 return reusableView; 23 24 }
5.设置push动画:
//定位按钮被点击 - (void)Localself { XHQFoundMoreViewController *more = [[XHQFoundMoreViewController alloc]init]; //push带动画 [self pushNextWithType:@"suckEffect" Subtype:@"fromLeft" Viewcontroller:more]; }
1 - (void)pushNextWithType:(NSString *)type Subtype:(NSString *)subtype Viewcontroller:(UIViewController *)viewController 2 { 3 CATransition *transition = [CATransition animation]; 4 transition.type = type; 5 transition.subtype = subtype; 6 transition.duration = 1; 7 viewController.hidesBottomBarWhenPushed = YES; 8 [self.navigationController .view.layer addAnimation:transition forKey:nil]; 9 [self.navigationController pushViewController:viewController animated:nil]; 10 11 }
6.封装图形的圆角设置:
1 + (void)layerCornerRadius:(CALayer *)dest radius:(float)radius width:(float)width color:(UIColor *)color 2 { 3 dest.cornerRadius = radius; 4 dest.borderWidth = width; 5 dest.borderColor = color.CGColor; 6 dest.masksToBounds = YES; 7 }
类方法调用:
1 [XHQAuxiliary layerCornerRadius:self.userface.layer radius:30 width:0 color:[UIColor yellowColor]];
7.实现夜间模式的开关按钮:
1 if(indexPath.row == 2) 2 { 3 UISwitch *swi = [[UISwitch alloc]init]; 4 [swi addTarget:self action:@selector(changeValue:) forControlEvents:UIControlEventValueChanged]; 5 cell.accessoryView = swi; 6 }
8.实现图头放大:
1 #pragma mark - 实现scrollView的代理方法 2 -(void)scrollViewDidScroll:(UIScrollView *)scrollView 3 { 4 //实现图头放大的核心思想：通过改变scrollView的偏移量来改变图片的frame 5 if(scrollView == self.tableView) 6 { 7 //获取scrollView的偏移量 8 float yOffset = scrollView.contentOffset.y; 9 10 11 NSLog(@"yoffset = %f",yOffset); //往下拉值越来越小 12 13 //scrollView的横向偏移量是随着纵向偏移量的变化而变化 14 float xOffset = (yOffset + ImageOriginHeight) / 2; 15 if (yOffset < -ImageOriginHeight) { 16 //改变imageView的frame 17 CGRect rect = _headerImageView.frame; 18 19 rect.origin.y = -yOffset; 20 rect.size.height = -yOffset * 2; 21 22 rect.origin.x = xOffset; 23 rect.size.width = XHQ_SCRWIDTH + fabs(xOffset) * 2; 24 25 _headerImageView.frame = rect; 26 // NSLog(@"%f💐%f",rect.origin.y, rect.size.height); 27 28 } 29 // NSLog(@"%f",yOffset); 30 } 31 }
9.实现夜间模式效果:
1 - (void)changeValue:(UISwitch *)swi 2 { 3 if (swi.on) { 4 //添加半透明view到window上 5 UIApplication * app = [UIApplication sharedApplication]; 6 AppDelegate *delegate = (AppDelegate *) app.delegate; 7 _darkView = [[UIView alloc]initWithFrame:self.view.frame]; 8 //设置view的背景色 9 _darkView.backgroundColor = [UIColor blackColor]; 10 _darkView.alpha = 0.3; 11 //关闭view的用户交互(响应者链) 12 _darkView.userInteractionEnabled = NO; 13 [delegate.window addSubview:_darkView]; 14 15 } 16 else 17 { 18 [_darkView removeFromSuperview]; 19 } 20 21 }
10.清除缓存实现:
1 - (float ) folderSizeAtPath:(NSString*) folderPath 2 { 3 NSFileManager* manager = [NSFileManager defaultManager]; 4 if (![manager fileExistsAtPath:folderPath]) return 0; 5 NSEnumerator *childFilesEnumerator = [[manager subpathsAtPath:folderPath] objectEnumerator]; 6 NSString* fileName; 7 long long folderSize = 0; 8 while ((fileName = [childFilesEnumerator nextObject]) != nil){ 9 NSString* fileAbsolutePath = [folderPath stringByAppendingPathComponent:fileName]; 10 folderSize += [self fileSizeAtPath:fileAbsolutePath]; 11 } 12 return folderSize/(1024.0*1024.0); 13 }
1 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES); 2 NSString *path = [paths lastObject]; 3 4 NSString *str = [NSString stringWithFormat:@"缓存已清除%.1fM", [self folderSizeAtPath:path]]; 5 6 NSArray *files = [[NSFileManager defaultManager] subpathsAtPath:path]; 7 for (NSString *p in files) { 8 NSError *error; 9 NSString *Path = [path stringByAppendingPathComponent:p]; 10 if ([[NSFileManager defaultManager] fileExistsAtPath:Path]) { 11 [[NSFileManager defaultManager] removeItemAtPath:Path error:&error]; 12 } 13 } 14
11.退出程序:
1 RESideMenuItem * item3 = [[RESideMenuItem alloc]initWithTitle:@"退出" action:^(RESideMenu *menu, RESideMenuItem *item) { 2 exit(0); 3 4 }];
看了别人的一个项目,只想说写的超级好呀,这逻辑,这封装......学习学习!!!
