你可以在添加蒙层时进行判断! line:60

// 遍历所有window，给它们加上蒙版
for (UIWindow *window in windows) {
    NSString *className = NSStringFromClass(window.class);
    if ([className isEqualToString:@"UIRemoteKeyboardWindow"]){
        return;
    }
    if (![className containsString:@"UIText"]) {
        [IMYAppGrayStyleCoverView showInMaskerView:window];
    }
}
