问题 Similar to this question: How to make ios App Store link with parameters? I am interested in passing parameters to the download link in the iOS app store. From what I've read, it seems that the parameters are only passed to the application if it was already installed, and the user tapped the smart app banner. What I want to do is pass parameters to the download link such that when a user downloads, the first time they open the app, the parameters will be passed. Mainly, I want to allow users

问题 I know there are many questions: "How to open setting app programatically?" and the answer is "BIG NO". I know that Apple does not support opening Settings from any other app after iOS 5.0. But there are some apps like MapMyFitness which can open Settings, and they are available in the App Store and have been approved by Apple. MapMyFitness opens the Bluetooth settings if Bluetooth is turned off. I have checked this in iOS 6 and iOS 5.1. I want to know how can these apps are able to open

问题 It seems in iOS 6, a drop shadow is automatically added to the navigation bar even when you set a custom background image. I'm pretty sure this wasn't the case with iOS 5 as when I test the same code in the iOS 5 and 6 sim, the shadow appears in iOS 6 but not 5. Does anyone know anything about this? Or how to enable/disable it? 回答1: Place this in your AppDelegate [[UINavigationBar appearance] setShadowImage:[UIImage new]]; // is IOS 7 and later [[UINavigationBar appearance] setBackgroundImage

问题 Does anyone have a short example of how to implement the new UIRefreshControl into xcode. I have a UITableViewController which displays Tweets, want to be able to pull down and refresh. 回答1: You can just set it up in your viewDidLoad , if you have a UITableViewController : UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:self action:@selector(refresh) forControlEvents:UIControlEventValueChanged]; self.refreshControl = refreshControl; Then you can

问题 Earlier I was on XCode 4.2 for a long time on Snow Leopard for a long time. I have made a straight jump to Mountain Lion with XCode 4.5 on with iOS 6 SDK and ARC. A lot has changed for me. Just wanted to know, whether the naming style of default variables has changed ? because in older XCode if I wont declare an ivar myself, it would take the same name as the property. In 4.5, I declared a property (no synthesize required anymore!). In the overidden setter, I am trying to use the variable as

问题 I developed IOS 5 application using game center. Now I want my code to run on IOS 6. So I have let my application to support both orientation i.e landscape and portrait so that it does not crashes when game center login screen pops up. But after that, my home view controller does not starts in landscape view. Instead when I go to a further view, it opens in landscape, and then when i come back, then the home view opens in landscape. But home view does not opens to landscape mode for the first

问题 Since the new SDK was release (iOS 6), the delegate method documentInteractionController:canPerformAction: of the UIDocumentInteractionControllerDelegate is deprecated. Using that method you were able to prevent default actions like print: and copy: to appear. The method is being called in the current version of iOS 6, but in future versions this method will not be called and my app will show actions that I don't want to support. I read the available documentation for the

问题 This question already has answers here : Difference between self.var and simply var (3 answers) Closed 6 years ago . I am quite new to Objective C and iOS, currently trying to learn app development using the iOS 6 SDK. One concept I really can't wrap my head around is the difference between "_variable" and "self.variable" when being accessed in the .m file. Are they the same? Or different? Following is a simple sample MyClass.h #import <Foundation/Foundation.h> @interface MyClass : NSObject

问题 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
