iOS UILabel实现部分字段更改样式使用

来源：互联网发布：欧佩克石油库存数据编辑：程序博客网时间：2024/06/05 02:14

利用iOS7的label特性对abel进行封装使用

对一段字符串当中的某段进行颜色变化,直接掉用加方法就可以显示

```

- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib.       UILabel *labelDemo = [[UILabel alloc] initWithFrame:CGRectMake(10, 50, 300, 40)];    [self.view addSubview:labelDemo];    NSString *originalString = @"今天是：星期日";    NSString *changeString = @"星期日";    labelDemo.attributedText = [ViewController changeLabelColorOriginalString:originalString changeString:changeString];}+ (NSMutableAttributedString *)changeLabelColorOriginalString:(NSString *)originalString changeString:(NSString *)changeString {    NSRange changeStringRange = [originalString rangeOfString:changeString];    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:originalString];    [attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:changeStringRange];    return attributedString;}

```

最终效果如图
