subview

I want to use addChildViewController in View (one view fro subviews array) but I don't know about that. this is my code : for (UIView *subview in self.view.subviews) { if (subview.tag == 1) { CartView *cart = [[CartView alloc]init]; [cart willMoveToParentViewController:????];/* (UIViewController*) from subview*/ [cart.view setFrame:CGRectMake(0.0f,CGRectGetHeight(self.view.frame),CGRectGetWidth(self.view.frame),CGRectGetHeight(self.view.frame))]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.3]; [cart.view setFrame:CGRectMake(0.0f,0,CGRectGetWidth(self.view.frame)

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 DrawRect portion of the code: var RPMPointerAngle: CGFloat { var angle: CGFloat = 2.0 return angle } What I

Is there anyway to detect a hidden state change (or other change) in a sub view in a UIView (not UIViewController). Would like to detect this async somehow. There are reasons for my madness. You can use KVO (key value observing) to detect a change to the value of the property hidden . Add your observer ( self in this example) in the following way: UIView* viewToObserve = [self getViewToObserve]; // implement getViewToObserve [viewToObserve addObserver:self forKeyPath:@"hidden" options:0 context:NULL]; Now add the following method to your observer class: - (void) observeValueForKeyPath:

iPhone / Objective-C On my view a little "hover" view appears after a user clicks on a button on the main view. When the user clicks this subview I want the subview to FlipFromRight to another view (same size). The main view underneath should stay. viewHot and viewCold are the subviews viewMain is the main one. Is this possible? Create another empty view in viewMain called viewHover and position it where you want the hover views to show. Then in IB add either viewHot or viewCold (not both) as a subview of viewHover. Then call a method like this to flip the views: -(void)flipViews { [UIView

I'm building an iOS app in swift with Xcode 6. I'm trying to embed a view controller with a table view in a scrollview. When the user drags in the table view, it is suppose to move the table, not the the scrollview that it is embedded in. I've made this illustration, to clearify my view and view controller hierachy: The red area is the content size area of the scrollview . The green and blue areas are different view controllers , embedded in the scrollview. The yellow area is a Text field in the blue view controller. The orange area is a table view in the blue view controller. I have enabled

When using autolayout, my understanding is that removing a subview ( while holding a reference to it of course), the removed subview still knows its autolayout constraints. However, when adding it back to the super view later, the subview no longer knows its frame size. Rather it seems to get a zero frame. I assumed that autolayout would auto size it to meet the constraints. Is that not the case? I thought auto layout meant don't mess with frame rects. Do I still need to set the initial frame rect when adding the subview, even with auto layout? Max MacLeod When removing the subview, all the

I have a UIWebview that is loaded as a subview when a user selects a tab on a UISegmentedControl . For some reason, I can not get it to allow pinch/zooming . I set the following code in the viewDidLoad: method, so it should work. self.myWebView = [[[UIWebView alloc] initWithFrame:self.view.frame] autorelease]; self.myWebView.backgroundColor = [UIColor whiteColor]; self.myWebView.scalesPageToFit = YES; self.myWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); self.myWebView.delegate = self; [self.view addSubview: myWebView]; I tried loading a
