问题 My problem is the following: I want to only allow Portrait orientation on all my ViewControllers except 1 ViewController which is supposed to allow both Portrait and landscapeLeft/Right. I have now spent almost 2 days into how to set orientation in IOS for different slides/ViewControllers. After some searching I found this thread here at stack: UITabBarController Rotation Issues in ios 6 I followed Kunani's example in that thread which I will post here to save all readers some time: Zack, I

问题 I want to display UIView on the bottom of the screen in portrait mode, so when a phone is rotated and horizontal orientation would reposition/resize all subviews, that one UIView would remain where it was, with the same size and original position (i.e. on the right end of horizontal orientation if it was on the bottom of portrait mode). Is there a good way to do it? 回答1: You can set the autoresizing mask like this: myView.autorezisingmask = UIViewAutorezingMaskFlexibleTopMargin; This will

问题 I'm making a simple timer as a part of an Android app using a handler to call a runnable which updates the UI. However, when the user changes the screen orientation, the app restarts. I looked into onSaveInstanceState(), but that won't help me. I notice that some video player apps continue to play video during screen orientation change. Is it possible to similarly keep my activity running? I don't want my timer to stop running when the user tilts their phone. Any ideas on how to fix this?

问题 My app is a tab bar application running on iPad. One of the tabs contains a UIPageViewController, which I implemented pretty much as per the tutorial here: Implementing UIPageViewController programmatically – without storyboarding. Everything works great, including rotation. However there is a problem - if I go to the tab containing the page view controller, then navigate to a different tab and change the orientation. Then navigation back to the tab containing the page view controller, it is

问题 The common way to create a font with GDI is to use the desired point size and the target device's vertical resolution (DPI) like this: LOGFONT lf = {0}; lf.lfHeight = -MulDiv(point_size, GetDeviceCaps(hdc, LOGPIXELSY), 72); ... HFONT hfont = CreateFontIndirect(&lf); Assuming the default MM_TEXT mapping mode, this converts point_size into the pixel height for the desired device. (This is a common approximation. There are actually 72.27 points in an inch, not 72.) (The minus sign means I want

问题 i have an activity with a fragment in it. I would like to handle the orientation change myself, so i updated the manifest to look like this: <activity android:name="com.test.app" android:configChanges="orientation|keyboardHidden"/> Then i updated the activity to look like this: @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); updateLayout(); } and @Override public void onCreate(Bundle savedInstanceState) { super.onCreate

问题 I want to slide in a UIDatePicker when my user taps on my table view date field, exactly as in the standard contact app, when the user taps on the birthday field. With one additional killer detail: It's in a tab bar application and I want the UIDatePicker to slide over the tab bar. And still rotates when the user puts her phone in the lanscape orientation. The way I show the UIDatePicker is to insert in the view, and then animate its position: [self.view addSubview: self.pickerView]; When I
