ios-simulator

The UIDocumentInteractionController appears to be non-functional in iPad Simulator ("iPhone Simulator" version 4.0, shipping with XCode 3.2.3, using iOS Version 3.2). I have a simple sample code presenting a PDF preview using UIDocumentInteractionController . It works on the device. On iPad presentPreview just returns NO, the UIDocumentInteractionController's delegate methods are not invoked. Any hint how to make it work? Confirming the same behaviour over here: calling - (BOOL)presentPreviewAnimated: returns NO on the simulator but works on the device. Thanks for pointing this out, I just

I have an iPhone Xcode project that currently only contains images for retina display (twice the size as normal and with a @2x.png suffix). When I run the app on the iPhone Simulator (non retina) the images are still being displayed. Does this mean I don't need to worry about including two sets of images: retina and non-retina? This all seems a bit odd. I would assume that no images would appear on a non retina device if there are no non-@2x files included. Note: I have not tested my app on a non retina device. Just the simulator. Even if it works, it's not good practice, and if you have a

Does anyone understand why this is happening? On any simulator all of the schemes are found with the following code: NSArray<NSLinguisticTagScheme> *availSchemes = [NSLinguisticTagger availableTagSchemesForLanguage:@"en"]; for (NSLinguisticTagScheme scheme in availSchemes) { NSLog(@"Tag scheme %@", scheme); } yielding the following: 2018-02-13 09:12:54.066970-0500 MY_APP[79671:5737063] Tag scheme Language 2018-02-13 09:12:54.067160-0500 MY_APP[79671:5737063] Tag scheme Script 2018-02-13 09:12:54.067300-0500 MY_APP[79671:5737063] Tag scheme TokenType 2018-02-13 09:12:54.067425-0500 MY_APP[79671

I suddenly getting the below error, which is not allowing any application to run in simulator. The app just crashes. dyld: Symbol not found: __dealloc Referenced from: /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation Expected in: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/usr/lib/libobjc.A.dylib in /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation Please suggest ! As mentioned in the Xcode 6.1 Release Notes , the issue is that you are linking against new frameworks

following situation: I want to send in app SMS. This is my code creating the MFMessageComposeViewController: -(void) showMessageComposerWithText:(NSString*)messageText telNumber:(NSString*)telNumber composeDelegate:(id)delegate { MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init]; if([MFMessageComposeViewController canSendText]) { controller.body = messageText; controller.recipients = [NSArray arrayWithObject:telNumber]; controller.messageComposeDelegate = delegate; [delegate presentModalViewController:controller animated:YES]; } } So I think this is

Context With iOS8 and extensions Apple introduced the App group containers ( more info here ). Problem We use it through NSFileManager 's containerURLForSecurityApplicationGroupIdentifier: method. It works well in production on AppStore (with both iOS8 and iOS7). Problem is since our team updated to Xcode 6.1 (6A1052d) , the method returns nil on Simulators. We searched a lot but we didn't manage to find any clues. Even this question or this one are not applicable here. TLDR: Question Does NSFileManager 's containerURLForSecurityApplicationGroupIdentifier: method works on your simulators? Is
