self.title = @"For iOS 6 & later";
NSMutableAttributedString*str = [[NSMutableAttributedStringalloc] initWithString:@"Using NSAttributed String"];
[str addAttribute:NSForegroundColorAttributeNamevalue:[UIColor blueColor] range:NSMakeRange(0,5)];
[str addAttribute:NSForegroundColorAttributeNamevalue:[UIColor redColor] range:NSMakeRange(6,12)];

CGSizesize = [labelsizeThatFits:CGSizeMake(label.frame.size.width,MAXFLOAT)];
NSLog(@"%f=====%f",size.height,size.width);
label.frame=CGRectMake(0, 50,self.view.frame.size.width, size.height);
[self.viewaddSubview:label];
让UILabel具有链接功能，点击后调用safari打开网址
UILabel*labelGovUrl = [[UILabelalloc]initWithFrame:CGRectMake(73.0,330.0,180.0,40.0)];
labelGovUrl.autoresizingMask= (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
labelGovUrl.text=@"侬侬官网 >";
labelGovUrl.backgroundColor= [UIColorclearColor];
labelGovUrl.textColor= [UIColorwhiteColor];
labelGovUrl.font= [UIFontfontWithName:@"Helvetica-Bold"size:14];
labelGovUrl.userInteractionEnabled=YES;
labelGovUrl.tag= K_NNGOV_WEBSITE_LABEL_URL;
UITapGestureRecognizer*tapGesture =
[[[UITapGestureRecognizeralloc]initWithTarget:selfaction:@selector(openURL:)]autorelease];
[labelGovUrladdGestureRecognizer:tapGesture];
[self.viewaddSubview:labelGovUrl];
[labelGovUrlrelease];
-(void)openURL:(UITapGestureRecognizer*)gesture{
NSInteger tag = gesture.view.tag;
NSString*url =nil;
if(tag == K_NNWEIBO_LABEL_URL) {
url =@"http://t.qq.com/yourgame/";
}
if(tag == K_NNGOV_WEBSITE_LABEL_URL){
url =@"http://www.zjnn.cn/";
}
[[UIApplicationsharedApplication]openURL:[NSURLURLWithString:url]];
}
让label自适应里面的文字，自动调整宽度和高度的
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0,0,0,0)];这个frame是初设的，没关系，后面还会重新设置其size。
[label setNumberOfLines:0];
NSString *s = @"string......";
UIFont *font = [UIFont fontWithName:@"Arial" size:12];
CGSize size = CGSizeMake(320,2000);
CGSize labelsize = [s sizeWithFont:font constrainedToSize:size lineBreakMode:UILineBreakModeWordWrap];
[label setFrame:CGRectMake:(0,0, labelsize.width, labelsize.height)];
[self.view addSubView:label];
这样就可以对s赋值让其自动调整其大小了。
