UILabel Text显示不同的颜色

UILabel的text实现不同的颜色。

NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"Using NSAttributed String"];
[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-BoldItalicMT" size:30.0] range:NSMakeRange(0, 5)];
[str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"HelveticaNeue-Bold" size:30.0] range:NSMakeRange(6, 12)];
[str addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Courier-BoldOblique" size:30.0] range:NSMakeRange(19, 6)];
attrLabel.attributedText = str;

UILabel的text实现字体不同大小

-(NSMutableAttributedString*) changeLabelWithText:(NSString*)needText
{
    NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:needText];
    UIFont *font = [UIFont systemFontOfSize:20];
    [attrString addAttribute:NSFontAttributeName value:font range:NSMakeRange(0,4)];
    [attrString addAttribute:NSFontAttributeName value:[UIFont fontWithHiraKakuProNW3:12] range:NSMakeRange(4,needText.length-4)];
    return attrString;
}

在viewDidLoad中调用

[self.capital_total setAttributedText:[self changeLabelWithText:@"124571024.58"]];
