viewcontroller

问题 I am working on a SpriteKit project and I'm struggling to pause the game when the iAd is clicked, and unpause when the iAd is dismissed. The main problem is pausing the Scene from the ViewController, I know that if I want to pause the Scene from the Scene.m I should use the code self.scene.view.paused = YES; however this code doesn't work in the ViewController. - (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave { //pause game } - (void

问题 My program has a while-loop that runs some code, generating various text statements as it goes along. The problem is that the UILabel only prints the last line of text in the series (my understanding is because it iterates too quickly). How do I get the label to print all of the text encountered, like one would see in console output? I looked at this link but the example doesn't seem to match my situation and not sure how to implement the fix (if that's even the right one): Update Label In

问题 All of the searches I've done focus on passing data between view controllers. That's not really what I'm trying to do. I have a ViewController that has multiple Views in it. The ViewController has a slider which works fine: var throttleSetting = Float() @IBAction func changeThrottleSetting(sender: UISlider) { throttleSetting = sender.value } Then, in one of the Views contained in that same ViewController, I have a basic line that (for now) sets an initial value which is used later in the

问题 Okay so here is the problem I'm running into: I am attempting to switch from one viewController that I named MenuViewController which contains my menu (obviously). I have a separate viewController named ViewController that contains my mapView . I would like to be able to double finger swipe left from my MenuViewController over to my mapView . I'm not exactly sure where to start. Also, I am using xib files, and not the storyboard. Running iOS 6. 回答1: UISwipeGestureRecognizer *swipeLeftGesture=

问题 I'm having a hard time finding the answer to this question I assume is not that hard. How can I reference methods and properties defined on a viewcontroller from a SKScene ? And building on that: How can you reference the ViewController from a SKScene that was loaded from within another SKScene? 回答1: A better option than my "back reference" answer is to use a protocol to explicitly define the methods that a SKScene subclass expects the UIViewController subclass to implement. Here are the

问题 I've searched on SO & elsewhere for MvvmCross & Modal, but the one existing answer isn't helping us. We're developing a cross-platform app using MonoTouch & MvvmCross, which seems to be pretty powerful combination. However, we're having a few issues with the navigation, which we're gradually cracking! The current problem is - The app runs with a TabBarController, and each tab has navigation to further levels - this works fine. The client however wants the "Start" button on one of the tabs to
