添加自定义方法 addLabel

实例

   UILabel *aLabel = [[UILabel alloc]initWithFrame:
   CGRectMake(20, 200, 280, 80)];
   aLabel.numberOfLines = 0;
   aLabel.textColor = [UIColor blueColor];
   aLabel.backgroundColor = [UIColor clearColor];
   aLabel.textAlignment = UITextAlignmentCenter;
   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 −

实例


- (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.
}
