问题描述
使用modalPresentationStyle时遇到问题。
我在tabbarcontroller的第一个视图控制器的viewDidload中调用以下函数
这样就显示了登录viewController当应用程序启动时
I have problem when using modalPresentationStyle.
I call the following function in my tabbarcontroller's first view controller's viewDidload
So that the login viewController is displayed when app launches
但问题是当我在横向模式下启动应用程序时，我可以正确地看到登录视图，并且我将iPad旋转到纵向模式的背景登录viewcontroller是我的第一个tabbar viewcontroller上升了大约20pixels
But the problem is when I launch app in Landscape mode I can see the login view correctly and I rotate the iPad to portrait mode the background of login viewcontroller that is my First tabbar viewcontroller goes up by about 20pixels
我创建了一个新的应用程序来检查，我发现这只会在我们使用tabbar时发生。
当App以纵向模式启动时，它的效果非常好！
I create a new app to check and I found this will only happend when we use tabbar.
and when App launches in portrait mode its works great!
-(void)gotoCredentials {
Login *objLoginViewController=[[Login alloc] initWithNibName:@"Login" bundle:nil];
UINavigationController *objnavigationController = [[UINavigationController alloc]
initWithRootViewController:objLoginViewController];
objnavigationController.modalPresentationStyle=UIModalPresentationFormSheet;
objLoginViewController.modalPresentationStyle=UIModalPresentationFormSheet;
[self presentModalViewController:objnavigationController animated:YES];
//[self.tabBarController presentModalViewController:objnavigationController animated:YES];
[objLoginViewController release];
objLoginViewController=nil;
[objnavigationController release];
objnavigationController=nil;
}
提前感谢！
推荐答案
抱歉通过设置标签栏控制器选择来修复它
sorry it is fixed by setting tabbar controller selection
[m_objTabBarController setSelectedIndex:0];
。我不知道发生在这里。
但我认为这样做是因为在解散FormSheet并更改选项卡然后看起来很好所以我尝试设置tabbar选择索引并且它工作得很好...
after creating tabbar. I dont know that happens here.
But I think to do so is because after dissmiss FormSheet and change the tab then looks fine so I try setting tabbar selected index and it work great...
