Label - 自定义方法

-(void)addLabel {
   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，如下所示:

- (void)viewDidLoad {
   [super viewDidLoad];
   
   //创建我们的标签的自定义方法称为
   [self addLabel];
   //Do any additional setup after loading the view， typically from a nib.
}
