效果图:

 

 

 

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 70, self.view.frame.size.width - 20, 20)];
    
    label.backgroundColor = [UIColor yellowColor];
    [self.view addSubview:label];
   
    NSString *str1 = @"不变色 ";
    NSString *str2 = @"变色内容";
   
    NSMutableAttributedString *string = [self setDoNotChangeTheContentTextString:str1 discolorationContentTextString:str2 changeWhatColour:[UIColor redColor] ImageViewString:@"call_inCall_ loudspeaker_select_icon"];
   
    [string appendAttributedString:[[NSMutableAttributedString alloc] initWithString:@"又可以拼接内容"]];
    
    label.attributedText = string;

 

/**
 图片与已变色文字

 @param unchangingStr 不变色内容
 @param changeStr 变色内容
 @param color 变颜色
 @param imgString 图片string
 @return 返回 图片与已变色文字
 */

- (NSMutableAttributedString *)setDoNotChangeTheContentTextString:(NSString *)unchangingStr discolorationContentTextString:(NSString *)changeStr changeWhatColour:(UIColor *)color ImageViewString:(NSString *)imgString{
    
    NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@%@",unchangingStr,changeStr]];
    
    [str addAttribute:NSForegroundColorAttributeName value:color range:NSMakeRange(unchangingStr.length,changeStr.length)];
    
    
    NSMutableAttributedString *goalTipStr = [[NSMutableAttributedString alloc] initWithAttributedString:str];
    NSTextAttachment *alertImg = [[NSTextAttachment alloc]init];
    alertImg.image = [UIImage imageNamed:imgString];
    alertImg.bounds=CGRectMake(0, -3, 17, 17);
    NSAttributedString *imgStr = [NSAttributedString attributedStringWithAttachment:alertImg];
    [goalTipStr insertAttributedString:imgStr atIndex:0];
    
    return goalTipStr;
    
}
