问题代码

解决办法

UIView *coverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, kScreenWidth, kScreenHeight - self.btmBonusShareView.height)];
[keyWindow addSubview:coverView];
__weak typeof(self) weakSelf = self;
__strong UIView *tempView = coverView;
[coverView setTapActionWithBlock:^{
    __strong typeof(self) pThis = weakSelf;
    [pThis removeBtmBonusShareViewAnimated: tempView];
}];

强烈推荐：超简单！！！ iOS设置状态栏、导航栏按钮、标题、颜色、透明度，偏移等
