UILabel設置多種字體、顏色
前言
開發中常用到的設置UILabel的文本樣式代碼片段:
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"Using NSAttributed String,try your best to test attributed string text"]; [str addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0,5)]; [str addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(6,12)]; [str addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(19,6)]; [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:30.0] range:NSMakeRange(0, 5)]; [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:30.0] range:NSMakeRange(6, 12)]; [str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:30.0] range:NSMakeRange(19, 6)]; UILabel *attrLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 150, 320 - 40, 90)]; attrLabel.attributedText = str; attrLabel.numberOfLines = 0;
說明
NSMutableAttributedString類可以添加各種樣式,常用的設置key有:
- NSForegroundColorAttributeName 設置前景色,也就是文本顏色
- NSFontAttributeName 設置字體
- NSBackgroundColorAttributeName 設置背景色
