为制作不同颜色的文本而编辑，您可以使用TTTAttributedLabel。下面是代码

TTTAttributedLabel *label = [[TTTAttributedLabel alloc] initWithFrame:CGRectMake(20, 20, 200, 200)];
NSString* text = @"Cutomer's First Name*";
[label setText:text afterInheritingLabelAttributesAndConfiguringWithBlock:^(NSMutableAttributedString *mutableAttributedString){
    //NSMutableAttributedString *mutableAttributedString;
    NSRange whiteRange = [text rangeOfString:@"*"];
    if (whiteRange.location != NSNotFound) {
        [mutableAttributedString addAttribute:(NSString *)kCTForegroundColorAttributeName value:(id)[UIColor redColor].CGColor range:whiteRange];
    }
    return mutableAttributedString;
}];
label.font = [UIFont fontWithName: @"Helvetica Neue" size: 10];
