全平台头像添加vip标识-视图封装思想

Posted 2020-12-17 huangzs

需求：全平台（整个APP）头像不同的vip级别添加不同的vip标识

样式：（圆形头像右下角添加vip标识）

 

为了便于调用，采用了 UIImageView 分类，添加方法，方法里添加一个 UIImageView 展示vip标识 的实现方式。直接上代码

1.新建 UIImageView+TJVipHead 分类

2..h里代码

@interface UIImageView (TJVipHead) @property(strong, nonatomic) UIImageView *vipMarkImageView;   /// VIP 标识宽度 默认 Ratio(16)*Ratio(16) /// @param vipLevel vip级别 /// @param vipStatus VIP 状态 -(void)addVipMarkWithVipLevel:(NSString *)vipLevel vipStatus:(NSString *)vipStatus;   @end

 

3..m里代码

@implementation UIImageView (TJVipHead)    -(void)addVipMarkWithVipLevel:(NSString *)vipLevel vipStatus:(NSString *)vipStatus {     if (![self.superview.subviews containsObject:self.vipMarkImageView]) {         self.vipMarkImageView = [[UIImageView alloc] init];         self.vipMarkImageView.size=CGSizeMake(Ratio(16), Ratio(16));         self.vipMarkImageView.right=self.right;         self.vipMarkImageView.bottom=self.bottom;         self.vipMarkImageView.backgroundColor = [UIColor clearColor];         self.vipMarkImageView.userInteractionEnabled=YES;         self.vipMarkImageView.image=nil;         [self.superview addSubview:self.vipMarkImageView];     }     [self.superview bringSubviewToFront:self.vipMarkImageView];     if (beNil(vipLevel)) {         vipLevel=@"0";     }     if (beNil(vipStatus)) {         vipStatus=@"0";     }     if (vipStatus.integerValue) {         //vip有效         //vipLevel//会员级别  1：普通；2：高级；3：特级；         switch (vipLevel.integerValue) {             case 0:                 self.vipMarkImageView.image=nil;                 break;             case 1:                 self.vipMarkImageView.image=[UIImage imageNamed:@"common_vip"];                 break;             case 2:                 self.vipMarkImageView.image=[UIImage imageNamed:@"common_vip_senior"];                 break;             case 3:                 self.vipMarkImageView.image=[UIImage imageNamed:@"common_vip_super"];                 break;             default:                 break;         }     } else {         //vip失效或者没开通         self.vipMarkImageView.image=nil;     } }       #pragma mark - Add a "vipMarkImageView" to this UIImageView class   NSString const *kKeyVipMarkImageView = @"kKeyVipMarkImageView"; -(void)setVipMarkImageView:(UIImageView *)vipMarkImageView {     objc_setAssociatedObject(self, &kKeyVipMarkImageView, (id)vipMarkImageView, OBJC_ASSOCIATION_RETAIN_NONATOMIC); } -(UIImageView *)vipMarkImageView {     return objc_getAssociatedObject(self, &kKeyVipMarkImageView); }   @end
