qlpreviewcontroller

I'm having issues trying to preview big files in my iPad app. In the app we use UIDocumentInteractionController. When we try to open big files (> 100 MB) the UIDocumentInteractionController only shows a grey screen with the name and size of the file. To narrow the problem we have done a simple app that only tries to preview a file using QLPreviewController and we find the same problem. The problem seems related with the memory usage. Because the biggest size of the file you can preview changes regarding the iPad model and the amount of apps in the background. Trying to preview the files with

I'm using the below code to use QLPreviewcontroller to show some documents in my app, let ql = QLPreviewController() ql.dataSource = self //ql.navigationItem.rightBarButtonItems = nil ql.navigationItem.rightBarButtonItem = nil presentViewController(ql, animated: true, completion: nil) I don't want the share button in the right top of QLPreviewcontroller.

Can anyone tell me how to remove the QLPreviewController print button? Also would like to disable cut/paste/copy. UPDATE: This no longer works in iOS 6. Quick Look runs in another process using XPC. See [here][3] for more details. I don't foresee any way to customize QLPreviewController. The following answer remains for anyone interested for pre-iOS 6. If you want to simply remove the action button you need to subclass QLPreviewController . Then in -viewWillAppear: you need to remove the action button by calling [[self navigationItem] setRightBarButtonItem:nil]; This will also remove the

Currently I'm using a QLPreviewController in a navigation controller. (pushViewController) To hide the navigationbar I use a UITapGestureRecognizer. The user can show/hide the navigation bar by a single touch (tap). This worked well in iOS5 - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)]; [tapRecognizer setNumberOfTapsRequired:1]; [tapRecognizer setDelegate:self]; [[self view] addGestureRecognizer:tapRecognizer]; [tapRecognizer release]; } - (BOOL
