2. 加边框
myWebView.layer.borderWidth = 5;
myWebView.layer.borderColor = [[UIColorcolorWithRed:0.52 green:0.09 blue:0.07 alpha:1] CGColor];
3. 清空View
for (UIView *subView in [controller.viewsubViews]){
[subViewremoveFromSuperview];
}
4. 添加navigationBar
[self.navigationController.view addSubview:self.navigationController.navigationBar];

5. 保存内存地址
[arrFriendretain];
6. 地图改变位置
- (void)gotoLocation:(CLLocationCoordinate2D)clloc
{
MKCoordinateRegionnewRegion;
newRegion.center= clloc;
newRegion.span.latitudeDelta= 0.01;
newRegion.span.longitudeDelta= 0.01;
[_googleView.mapsetRegion:newRegion animated:YES];
}

7. 进制转化
-(CFStringRef)EncodeUTF8Str:(NSString*)encodeStr{
CFStringRefnonAlphaNumValidChars = CFSTR("![ DISCUZ_CODE_1 ]’()*+,-./:;=?@_~"); 
CFStringRefpreprocessedString = CFURLCreateStringByReplacingPercentEscapesUsingEncoding(kCFAllocatorDefault, (CFStringRef)encodeStr, CFSTR(""), kCFStringEncodingUTF8); 
CFStringRefnewStr =CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,preprocessedString,NULL,nonAlphaNumValidChars,kCFStringEncodingUTF8);
returnnewStr;
}

//转换成GB2312
-(NSString*)EncodeGB2312Str:(NSString*)encodeStr{ 
CFStringRefnonAlphaNumValidChars = CFSTR("![ DISCUZ_CODE_1 ]’()*+,-./:;=?@_~"); 
NSString*preprocessedString = (NSString*)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(kCFAllocatorDefault, (CFStringRef)encodeStr, CFSTR(""), kCFStringEncodingGB_18030_2000); 
NSString*newStr = [(NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,(CFStringRef)preprocessedString,NULL,nonAlphaNumValidChars,kCFStringEncodingGB_18030_2000) autorelease]; 
[preprocessedStringrelease]; 
returnnewStr; 
} 
8. 时间格式转换
NSString*strTime=[NSStringstringWithFormat:@"%@",message.time];


NSDateFormatter*inform = [[NSDateFormatteralloc] init];
[inform setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSDate*parsed = [inform dateFromString: strTime];
[inform release];

NSDateFormatter*toform = [[NSDateFormatteralloc] init];
[toform setDateFormat:@"MM-dd HH:mm"];

cell.lblTime.text=[toform stringFromDate:parsed];
[parsed release];
[toform release];




//时间格式转换
NSString*strTime=[NSStringstringWithFormat:@"%@",message.time];
if([strTime length]>16) {
strTime=[strTime substringWithRange:NSMakeRange(5, 11)];
}

9. 类
[[Fraction class] t]; 
或者
Class clazz=[Fraction class];
[clazz t];


10. 内存
NSLog(@"arrFriend count=%d",[arrFriendretainCount]);
地图
控制地图的中心和显示大小
MKCoordinateRegionnewRegion;
newRegion.center= clloc;
newRegion.span.latitudeDelta=0.9;//0.01
newRegion.span.longitudeDelta= 0.9;
[_googleView.mapsetRegion:newRegion animated:YES];
[self.viewinsertSubview:mapView atIndex:0];
11. 动画
[UIViewbeginAnimations:@"hideView"context:nil];//开始动画　动画名称
[UIViewsetAnimationDuration:0.2];//动画速度
[UIViewsetAnimationCurve:UIViewAnimationCurveLinear];//动画方向
scrollVGlide.frame=CGRectMake(0, 0, 320, 200);
scrollVGlide.contentOffset=CGPointMake(0, 45);
[UIViewcommitAnimations];//结束动画
12. view 里的视图
for(UIView*v in[self.viewsubviews]) {
if([v isKindOfClass:[UIButtonclass]]==NO) {
[v removeFromSuperview];
}
} 

13. 读取本地文件　内容

NSString*filePath=[[NSBundlemainBundle] pathForResource:@"1"ofType:@"txt"];
NSString*str=[[NSStringalloc] initWithContentsOfFile:filePath];
NSLog(@"%@",str);

14. 提取字符串
// 得到引用的用户名　和发表时间
-(NSString*)WebQuoteUserTime:(NSString*)strText
{
NSString*strResult=[[[NSStringalloc] init]autorelease];
NSString*strMiddle=strText;
NSRangerangQuote1=[strMiddle rangeOfString:@"[quote]"];
NSRangerangQuote=[strMiddle rangeOfString:@""];
NSRangerangSize=[strMiddle rangeOfString:@""];
if(rangQuote1.length>0&&rangQuote.length>0&&rangSize.length>0) {
strResult=[strMiddlesubstringWithRange:NSMakeRange(rangQuote.location+rangQuote.length,rangSize.location-rangQuote.location-rangQuote.length)];
}
returnstrResult;
}


15. xml序列化和反序列化 
xml转换成对象称为反序列化
对象转换成xml 称为序列化
16. mac翻..阿..城墙
vbn系统自带的
17. NSString 初始化
Nsstring *str=nil;//如果不初始化访问的地址会有错不确定
18. 属性定义
@property(nonatomic,assign)NSInteger nodeCount;
@property(nonatomic,assign) NSInteger unreadMsgSum;
@property(nonatomic,retain)CatalogIDListClass *catalogIDList;

@property(nonatomic,retain)MessageInfoListClass *messageInfoList;
@property(nonatomic,copy)NSString *parentcatalogID;
@property(nonatomic,copy)NSString *Etag_Catalog;
19. 属性 也要再定义
也要释放如果用retain 当变量改变是也可以在改变
20. 每隔一段时间 执行 事件
[NSTimerscheduledTimerWithTimeInterval:0.5target:selfselector:@selector(makeMyProgressBarMoving)userInfo:nilrepeats:NO];
21. 页面推送方式
[selfpresentModalViewController:picker animated:YES];

22. 命令打开 svn
cddesktop/megafon
svnst .
svnupdate

就可以了
23. UITableView
- (NSArray*)sectionIndexTitlesForTableView:(UITableView*)tableView
{

NSStringEncodingenc = CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000);
NSString*returnString=[[NSStringalloc]initWithData:returnData encoding:enc];
[returnData release];

if([returnString length]>42) {
returnString=[returnStringsubstringFromIndex:42];
}
else{
NSLog(@"returnString数据不对");
}

NSError*error;
NSDictionary*dict= [XMLReaderdictionaryForXMLString:returnString error:&error];

returndict ;


31. 简体中文编码
