UI里面有很多控件比如UIView UIControl UILabel UIButton UIScrollView UIWindow UIWebView UITabBar UITableView UITableViewCell UIToolbar UITextField UITextView UIImageView UIPageControl UIPickerView UIProgressView UIAlertView UISearchBar UISegmentedControl UISearchBar UISlider UISwitch UICollectionView 6.0 UICollectionReusableView等
控制器有
UIPageViewController UIPopoverController UIImagePickerController UINavigationController UISplitViewController UICollectionViewController UITableViewController
开在写了,废话少说,
先将UILabel UIView和UIResponder后面在写,
UILabel的
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
UILabel*aLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 100, 280, 100)];
aLabel.backgroundColor = [UIColor greenColor];
aLabel.text=@"这是我在2013年的程序,今天也是我要写ios、mac和操作系统相关的技术博文,我的bolg分别是(1)http://www.cnblogs.com/leevaboo(2)http://blog.csdn.net/leevaboo,(3)http://3660064.blog.51cto.com";
aLabel.textAlignment= NSTextAlignmentCenter;//左中右对其的模式 default is left
aLabel.textColor = [UIColor blueColor];//文本颜色default is blackColor
aLabel.font = [UIFont systemFontOfSize:20];//字体的大小default is 17
aLabel.shadowColor = [UIColor redColor];//阴影default is nil
aLabel.shadowOffset = CGSizeMake(0,1);//阴影的位置,按照xy轴的坐标位置来,default is (0 -1)表示x = 0 ,y = -1 表示在阴影在正下方 x轴左到右是负到正,y上到下是负到正
aLabel.lineBreakMode = NSLineBreakByTruncatingTail;//文本超过label的边界的文本截取方式default is NSLineBreakByTruncatingTail
aLabel.highlightedTextColor = [UIColor purpleColor];//设置文本的高亮颜色 default is nil
aLabel.highlighted = NO;//打开高亮default is NO
aLabel.userInteractionEnabled = NO;//是否交互.default is NP
aLabel.adjustsFontSizeToFitWidth = NO;//根据宽调整字体的大小 但是numberOfLines = 1;default is NO
aLabel.numberOfLines = 0;
float height = [aLabel.text sizeWithFont:aLabel.font constrainedToSize:CGSizeMake(280, 100000) lineBreakMode:NSLineBreakByWordWrapping].height;//根据字符串的长度和字号的大小和Label的宽度自动计算label的高度
aLabel.baselineAdjustment = UIBaselineAdjustmentAlignBaselines;//设置label的基准线
aLabel.frame = CGRectMake(20, 100, 280, height);
[self.view addSubview:aLabel];
[aLabel release];
// Do any additional setup after loading the view.
