PSPushPopPressView is a custom view that provides direct manipulation for your content - like the images and videos in Our Choice by Push Pop Press. All credit for coming up with the interaction and use of such an interaction goes to Push Pop Press. This view tries to imitate the interaction they have perfected in Our Choice.
Credits go to Martin Reichart by Blacksmith Software, who sent me a initial implementation.
Be sure to test this on an real iPad, not the Simulator - it's much more awesome to feel it. And use all of your fingers, you can manipulate multiple views concurrently!
Zoom, Rotate, Drag - everything at the same time. In this example, the background is zoomed out and transparency is added while the transform is active.
PSPushPopPressView uses ARC and works with iOS 4.0 upwards. You need at least Xcode 4.2 with LLVM 3.0 to compile it.
Create an instance of PSPushPopPressView, insert it into your view hierarchy and you're done.
// create the push pop press container PSPushPopPressView *pushPopPressView = [[PSPushPopPressView alloc] initWithFrame:CGRectMake(140, 20, 500, 400)]; pushPopPressView.pushPopPressViewDelegate = self; [self.view addSubview:pushPopPressView];
You can add any UIView to the container. Just make sure it's autoresizable (else it won't look that great). Also note that adding subviews which offer userInteraction on their own (e.g. UIWebView or UIScrollView) might mess up the interaction with the view.
// add a cat image to the push pop press view UIImageView *catImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cat.jpg"]]; catImage.frame = pushPopPressView.bounds; catImage.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; catImage.clipsToBounds = YES; [pushPopPressView addSubview:catImageView];
This is just a simple example. In the Example project, there's code how to embed video this way, and also code that 'zooms out' the whole view like you've probably seen in OurChoice.
You can set yourself as a PSPushPopPressView to receive callbacks when the user starts/stops manipulating the view or when the view will/did go into fullscreen or back to it's original frame.
Shadow animation is tricky, and sometimes the animation looks pretty bad.
Touches are sometimes not correctly recognized, which leads to manipulation even though the delegates tell you no one's dragging it atm.
When a animating and rotating at the same time, sometimes the view frame is reset incorrectly.
Don't worry - it works pretty well, and is used for month now in production - people love it!
