由 与世无争的帅哥 提交于 2019-11-27 01:06:59

This makes sense because the instance of the UIWebView persists between sessions and is only released when the memory is needed. However, I would

问题 I want to have the same effect as the birthday date setter in the iPhone contacts app. How do I have a modal date picker come up only halfway on the screen.

Thanks in advance. 回答1: By far, the best way to achieve a date-picker/uipicker keyboard-like is to use the input view property of a textfield: Build a

问题 I have a couple of modal view controllers of certain size. I'm trying to avoid the use of custom views (creating full screen black translucent overlay over current view, add the modal view over that view, do the animations, etc) to present it because there is no modalPresentationStyle that fits the size of my controllers. Now I'm using UIModalPresentationPageSheet but my view is smaller in height and I have an ugly blank space Desired presentation _______________ | _______ | | | | | | | MyVC

trying to update a UILabel on a parent view controller when dismissing the modal view

由 你离开我真会死。 提交于 2019-11-26 21:57:48
问题 I am trying to update a UILabel in a parent View after someone makes a change in a modal view. So, after they click "save" ... the newly entered value would change what text is displayed on the parent view controller. But, I can't seem to get that UILabel to refresh the newly entered value.

UIModalTransitionStylePartialCurl doesn't get back to previous state. (Not dismissing)

由 久未见 提交于 2019-11-26 21:07:19
I've got 2 view controllers, let's say A and B. In A, I'm calling B to be shown with transition style UIModalTransitionStylePartialCurl [b setModalTransitionStyle:UIModalTransitionStylePartialCurl]; [self presentModalViewController:b animated:YES]; It is working fine. However when I press the curled area in the program compiled with iOS 4.3. It does not dismiss at all. It doesn't get back to A view controller... What the most interesting is that this curl is active and giving response in the app compiled with iOS 5.0. How can I resolve this problem? Moreover, why doesn't it dismiss the B view
