修改label中不同文字的颜色:
```
(void)editStringColor:(NSString)string editStr:(NSString)editStr color:(UIColor *)color {
// string为整体字符串,editStr为需要修改的字符串
NSRange range =[string rangeOfString:editStr];
NSMutableAttributedString *attribute =[[NSMutableAttributedString alloc]initWithString:string];
//设置属性修改字体颜色UIColor与大小UIFont
[attribute addAttributes:@{NSForegroundColorAttributeName:color} range:range];
self.label.attributedText = attribute;
}
```
