等级显示小控件

等级控件效果图:

实现方式：

自定义小控件，通过frame来获取它的坐标，然后通过富文本的方式来实现不同文字，由于文字粗体和斜体要同时使用，所以通过富文本实现比较方便；

声明文件：

其中有两个方法，一个是初始化，一个是改变等级需要调用的方法；

#import <UIKit/UIKit.h>

@interface IDSLevelconView : UIImageView

@property (nonatomic, strong) UILabel *levelabel;

- (instancetype)initWithIconLevel:(NSInteger)level;

- (void)updateLevel:(NSInteger)level;

@end

实现代码
