话不多说，直接上代码。将代码里WYTabBarController换成你自己的根视图是tabbar
#pragma mark 判断当前页面
- (UIViewController *)presentingVC{
UIWindow * window = [[UIApplication sharedApplication] keyWindow];
if (window.windowLevel != UIWindowLevelNormal){
NSArray *windows = [[UIApplication sharedApplication] windows];
for(UIWindow * tmpWin in windows){
if (tmpWin.windowLevel == UIWindowLevelNormal){
window = tmpWin;
break;
}
}
}
UIViewController *result = window.rootViewController;
while (result.presentedViewController) {
result = result.presentedViewController;
}
if ([result isKindOfClass:[WYTabBarController class]]) {
result = [(WYTabBarController *)result selectedViewController];
}
if ([result isKindOfClass:[UINavigationController class]]) {
result = [(UINavigationController *)result topViewController];
}
return result;
}
