As far as I understand you cannot download the SDK separately – and even if you could, I wouldn’t recommend it. Using the bundled SDK+Xcode release is the best idea in my opinion, as it will be working for you out of the box. I know it’s annoying having to download such a large amount … Read more
Note, from 2014 onwards: just to be clear, this is now built in to iOS… Click to accessibility, click “guided access”. Conrats for “inventing” it, PlanetUnknonw! 🙂 The answer below is only of historic value… For the record, it’s silly that people are saying “Why would you want to do this?” it’s a great idea … Read more
Our app uses the MPMediaPLayer. We also had the idleTimerDisabled=YES code in the ApplicationFinishedLaunching, which works EXCEPT if untethered, and there is already a current nowPlayingItem which is left playing (or unpaused, if paused at app startup). Obviously this is all with the Settings -> General -> Autolock set to some timed value. By adding … Read more
Took a sec (and some deviousness) but I figured it out. Put a video file into your application’s Documents directory, I tried a .MOV but that didn’t work, a .m4v worked. Then put this early in your app (I just stuck it in application:didFinishLaunchingWithOptions): NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@”Documents/myMovie.m4v”]]; UISaveVideoAtPathToSavedPhotosAlbum(path, self, @selector(video:didFinishSavingWithError:contextInfo:), nil); And … Read more
I was not able to get it working even when I read all of your answers. I’m presenting ready code that will work for everyone. Let’s say we have a controller class named Controller. You can simply paste the following code to this controller to have the menu working on its view: – (void)loadView { … Read more
The source code (as hotpaw2 said) is only available to Apple, but there are multiple ways you can see what’s going on: Using the program class-dump (example output for UIKit: https://github.com/kennytm/iphone-private-frameworks/tree/master/UIKit/ ), you can view all the private methods and instance variables of the UIKit classes, to see how they implement them at a higher … Read more
I have found one method which I tried myself: // Get the PDF Data from the url in a NSData Object NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[ NSURL URLWithString:@”http://www.example.com/info.pdf”]]; // Store the Data locally as PDF File NSString *resourceDocPath = [[NSString alloc] initWithString:[ [[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:@”Documents” ]]; NSString *filePath = [resourceDocPath stringByAppendingPathComponent:@”myPDF.pdf”]; [pdfData … Read more
Implement UITabBarControllerDelegate e.g. in your app delegate’s applicationDidFinishLaunching – (void)applicationDidFinishLaunching:(UIApplication *)application { tabBarController.delegate = self; [window addSubview:tabBarController.view]; } Then implement either: – (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController; – (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController; The first method is called before the view switch and gives you a chance to ‘veto’ the view switch by returning NO The second … Read more
Here is a scroll view guide from Apple The basic steps are: Create a UIScrollView and a content view you want to put inside (in your case a UIImageView). Make the content view a subview of the scroll view. Set the content size of the scrollview to the frame size of the content view. This … Read more
This can be done by utilizing the UIScrollView delegate method scrollViewWillBeginDecelerating to automatically set the content offset to the current screen position. To implement: Assign a delegate to your UIScrollView object if you have not already done so. In your delegate’s .m implementation file, add the following lines of code: -(void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView{ [scrollView setContentOffset:scrollView.contentOffset animated:YES]; … Read more
