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.
}
