在项目开发中，经常会遇到同一行文本显示的字体颜色和大小不一样，看着可以使用两个label来进行布局，实则显得麻烦，因为设置固定字体大小，那么在不同屏幕大小的手机有可能文本之间显示有间隙，也有可能出现......，这样还是在同一个label中显示比较好。如下：

- (void)viewDidLoad {
        [super viewDidLoad];
        
        UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(80, 100, 200, 300)];
        label.textColor = [UIColor blackColor];
        label.numberOfLines = 0;
        label.font = [UIFont systemFontOfSize:12];
        [self.view addSubview:label];
        
        //不同字体颜色
        float unit = 2.123;
        NSString *strNumber = [NSString stringWithFormat:@"单价价值：1人次/￥%@",[NSString stringWithFormat:@"%.2f",unit]];
        NSMutableAttributedString *str_number = [[NSMutableAttributedString alloc] initWithString:strNumber];
        NSString *strLength = [NSString stringWithFormat:@"￥%.2f",unit];
        [self setDiffString:str_number withString:@"单价" loaction:0 textColor:[UIColor redColor] textSize:@"Arial-BoldItalicMT" size:30.0];
        [self setDiffString:str_number withString:strLength loaction:9 textColor:[UIColor greenColor] textSize:@"HelveticaNeue-Bold" size:10.0];
        label.attributedText = str_number;
    }
    
    #pragma mark - 同一label设置不同颜色、字体
    - (void)setDiffString:(NSMutableAttributedString *)str_number withString:(NSString *)str_jq loaction:(NSInteger)loca textColor:(UIColor *)color textSize:(NSString *)fontName size:(CGFloat)size
    {
        [str_number addAttribute:NSForegroundColorAttributeName value:color range:NSMakeRange(loca,[str_jq length])];
        [str_number addAttribute:NSFontAttributeName value:[UIFont fontWithName:fontName size:size] range:NSMakeRange(loca,[str_jq length])];
    }

效果如下：
