全平台头像添加vip标识-视图封装思想

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
