Question

In the iPhone, I have a tableview, and touching the cells, I have one method calling presentModalViewController, and opening another view, with email and this kind of stuff. When the user press the cancel button, the viewWillAppear method in the previous view is called. So far, so good. But in the iPad, the viewWillAppear is only called the first time that the view appears, anyone knows if this is a bug or it s right? I tried to implement the

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{

没有成功。

Does anybody know how to fix this without doing any delegate method from scratch? Thanks in advance

由于观察控制员提出的方式不一定完全掩盖了iPad的基本观点,因此,当这些模式的观察控制员被解职时,观察WillAppear方法不会火灾。我依靠代表的方法向原观点控制者宣布模式观察控制者的行动。我认为,这是最好的前进道路。

基于猜测，而非阅读、测试或任何有用的事情，但因此不受保密协议的限制...

当你presentModalViewController时，viewWillDisappear是否被调用？可能它认为模态视图没有完全遮盖原始视图，因此（不像iPhone），两者同时存在？

很有可能是个漏洞，我会在苹果的这里提交一个漏洞报告。
