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

 

#import "IDSLevelconView.h"

@implementation IDSLevelconView

- (instancetype)initWithIconLevel:(NSInteger)level
{
   
    if (self = [superinit]) {
        [selfsetupView:level];

    NSMutableString * subtitlelabelStr = [NSMutableStringstringWithFormat:@"Lv%ld", level];
    NSString *content = subtitlelabelStr;
    NSMutableAttributedString *attributedString = [[NSMutableAttributedStringalloc] initWithString:content];
   
    [attributedString setAttributes:@{NSForegroundColorAttributeName:NF_Color_C1,NSFontAttributeName:[UIFontboldSystemFontOfSize:Near_Final_Font_T12]}range:NSMakeRange(0, 2)];
    [attributedString setAttributes:@{NSForegroundColorAttributeName:NF_Color_C1,NSFontAttributeName:[UIFontboldSystemFontOfSize:Near_Final_Font_T2]}range:NSMakeRange(2, [content length]-2)];

    self.layer.masksToBounds = YES;
}
