Mac开发-Label

cocoa中并没有UILabel,也没有NSLabel,cocoa中的label实际上是NSTextField，并将editable = No，来实现显示效果。

 NSTextField * label0 = [[NSTextField alloc] init];
    label0.editable = NO;
    label0.bordered = NO;//不显示边框
    label0.backgroundColor = [NSColor greenColor];//控件背景色
    label0.textColor = [NSColor magentaColor];//文字颜色
    label0.font = [NSFont systemFontOfSize:10];
    label0.alignment = NSTextAlignmentCenter;//水平显示方式
    label0.maximumNumberOfLines = 2;//最多显示行数
    label0.frame = NSMakeRect(100, 100, 100, 100);
    //label0.stringValue = @"测试文字聚会旧时代加夫里什江东父老j";//现实的文字内容
  
    
    //富文本用法
    NSString * linkURLText = @"http://www.apple.com/";
    NSString * text = [NSString stringWithFormat:@"please visit %@",linkURLText];
    
    NSURL * linkURL = [NSURL URLWithString:linkURLText];
    
    NSRange selectedRange = [text rangeOfString:linkURLText];
    
    NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:text];
    
    [string beginEditing];
    
    [string addAttribute:NSLinkAttributeName value:linkURL range:selectedRange];
    [string addAttribute:NSForegroundColorAttributeName value:[NSColor blueColor] range:selectedRange];
    [string addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:selectedRange];
    
    [string endEditing];
    
    label0.attributedStringValue = string;
    [self.view addSubview:label0];
