添加自定義方法?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.textAlignment = UITextAlignmentCenter;
    aLabel.text = @"This is a sample textn of multiple lines.
    here number of lines is not limited.";
    [self.view addSubview:aLabel];
}

在?ViewController.m?中更新?viewDidLoad，如下所示:

- (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.
