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. }
