iOS - Labels(標籤)

Label標籤用法

在IOS中 Label(標籤)用於顯示靜態的內容,可以是一個單一的一行或多行。

重要的屬性

  • textAlignment

  • textColor

  • text

  • numberOflines

  • lineBreakMode

添加一個自定義的方法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 text
of multiple lines.
here number of lines is not limited."; [self.view addSubview:aLabel]; }

更新在ViewController.m 中方法 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. }
