iOS - 标签

    标签用于显示静态内容,由单行或多行组成。
  • 重要属性

    • textAlignment
    • textColor
    • text
    • numberOflines
    • lineBreakMode
  • 添加自定义方法 addLabel

    
    -(void)addLabel {
       UILabel *aLabel = [[UILabel alloc]initWithFrame:
       CGRectMake(20, 200, 280, 80)];
       aLabel.numberOfLines = 0;
       aLabel.textColor = [UIColor blueColor];
       aLabel.backgroundColor = [UIColor clearColor];
       aLabel.textMoognment = UITextMoognmentCenter;
       aLabel.text = @"This is a sample text\n of multiple lines.
       here number of lines is not limited.";
       [self.view addSubview:aLabel];
    }
    
    更新 ViewController.m 中的 viewDidLoad 如下 -
    
    - (void)viewDidLoad {
       [super viewDidLoad];
       
       //The custom method to create our label is called
       [self addLabel];
       // Do any additional setup after loading the view, typically from a nib.
    }
