修改label中不同文字的顏色:
```
(void)editStringColor:(NSString)string editStr:(NSString)editStr color:(UIColor *)color {
// string為整體字符串,editStr為需要修改的字符串
NSRange range =[string rangeOfString:editStr];
NSMutableAttributedString *attribute =[[NSMutableAttributedString alloc]initWithString:string];
//設(shè)置屬性修改字體顏色UIColor與大小UIFont
[attribute addAttributes:@{NSForegroundColorAttributeName:color} range:range];
self.label.attributedText = attribute;
}
```
