iOS中UILabel显示不同的字体和颜色

    UILabel *label = [[UILabel alloc] initWithFrame:(CGRectMake(0, 100, 375, 30))];
    [self.view addSubview:label];
    NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:@"addAttribute:NSForegroundColorAttributeName"];
    [string addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithRed:1.000 green:0.713 blue:0.439 alpha:1.000] range:NSMakeRange(0, 13)];
    [string addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithRed:0.591 green:1.000 blue:0.858 alpha:1.000] range:NSMakeRange(13, 17)];
    [string addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithRed:0.692 green:0.439 blue:1.000 alpha:1.000] range:NSMakeRange(30, 13)];
    [string addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"HelveticaNeue-Bold"size:14.0] range:NSMakeRange(0, 13)];
    [string addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial-BoldItalicMT"size:14.0] range:NSMakeRange(13, 17)];
    [string addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Courier-BoldOblique"size:14.0] range:NSMakeRange(30, 13)];
    label.attributedText = string;
