A UIWindow that can be used to zoom in a specific UIView and displays it fullscreen

Read Me

This class provides a simple way to zoom a specific UIView and display it fullscreen, upon a defined action of the user (uses UIGestureRecognizer to detect actions). If the user performs the action on the specified UIView the view gets zoomed in animated and is displayed fullscreen, with a black background. If the user performs the same gesture again, the UIView gets zoomed back out and everything is like it was before.

This is a simple way that feels lighter to the user then pushing an own UIViewController just for displaying something in fullscreen.

Usage

You can use MTZoomWindow like this:

// specify size of the UIView when it is zoomed in
viewToZoom.zoomedSize = CGSizeMake(300,460);
viewToZoom.zoomedAutoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
viewToZoom.wrapInScrollviewWhenZoomed = YES;

// find this awesome shortcut for UITapGestureRecognizer in @zwaldowski's BlocksKit
[viewToZoom whenTapped:^{
    [viewToZoom zoomIn];
}];

Adding MTZoomWindow to your project

1. Just copy over the files MTZoomWindow.h, MTZoomWindow.m, UIView+MTZoom.h, UIView+MTZoom.m and MTZoomWindowDelegate.h to your project.
2. import "MTZoomWindow.h" everywhere where you want to use it
3. There is no step 3 :)

Known Issues

When your App supports landscape orientation you have to create MTZoomWindow in your AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // ...
    // create ZoomWindow to listen for orientation changes
    [MTZoomWindow sharedWindow];

    return YES;
}

MTZoomWindow Does not support horizontal screen, or I use the wrong

Zoom window doesn't handle rotation properly

I have an app that can rotate to any orientation on the iPad. Sometimes when I zoom in on a view, the zoomed view comes up sideways. It seems to depend on how the iPad was orientated when I started up the app.

Also, when the iPad is rotated while the zoomed in view is visible, the zoomed image shrinks to a tiny square in the corner of the black screen - its the same as the zoomed out size.

Wrong orientation on ios 6

When zooming fullscreen (on ios 6) zoomed view gets wrong orientation.
