DMCustomModalViewController is a UIViewController subclass which take a root view controller and present it modally with a nice animation (a la gmail).

You should not subclass it, it act as a container view controller that you can directly instantiate and use.

For iOS 7 and later

Features

DMCustomModalViewController provide a quick and an easy solution to display modal view controller with a nice animation. It have an option to display the modal view controller not full screen and keeping the current view controller in the background with a nice overlay on it.

1. 2 ways of presenting it, fullscreen or not full screen.
2. Nice animations!
3. Keep the current context and display the view in background and add an onverlay on it.
4. More to come.

How to use it

TL;DR: Look at the example provided.

Run the example and install it manually

Run pod installin the example folder

1. Add DMCustomModalViewController.h and .m from the classes/ folder to your Xcode project.
2. Add QuartzCore.framework to "Link Binary With Libraries" (.xcodeproj -> Build Phases)
3. Import DMCustomModalViewController.hwhere you want to use it.

Full Screen

ModalRootViewController *root = [[ModalRootViewController alloc]initWithNibName:nil bundle:nil];
_fullScreenModal = [[DMCustomModalViewController alloc]initWithRootViewController:root
                                                                               parentViewController:self];
[self.fullScreenModal setDelegate:self];
[self.fullScreenModal presentRootViewControllerWithPresentationStyle:DMCUstomModalViewControllerPresentFullScreen controllercompletion:^{

}];

Part screen

ModalRootViewController *root = [[ModalRootViewController alloc]initWithNibName:nil bundle:nil];
_partModal = [[DMCustomModalViewController alloc]initWithRootViewController:root
                                                                               parentViewController:self];
[self.partModal setDelegate:self];
self.partModal.rootViewControllerHeight = 350;
[self.partModal presentRootViewControllerWithPresentationStyle:DMCustomModalViewControllerPresentPartScreen controllercompletion:^{

}];

If you are not presenting it fullscreen you need to set the rootViewControllerHeight property. This value will be used to know how much of your rootViewController need to be displayed

Dismiss

DMCustomModalViewController provide a built in category, just import the .h of DMCustomModalViewController in your rootViewController you passed to the instance of DMCustomModalViewController, you will have access to a new property customModalViewController. You can then freely dismiss the modal from itself.

[self.customModalViewController dismissRootViewControllerWithcompletion:^{

}];

A better implementation would be to build yourself some delegate for your rootViewController, so the controller which fired the modal would be also responsible for dismissing it.

Delegate

DMCustomViewController currently provide one delegate method to inform you when it was dismissed.

@protocol DMCustomViewControllerDelegate <NSObject>
@optional
- (void)customModalViewControllerDidDismiss:(DMCustomModalViewController *)modalViewController;
@end

Customization

You can customize the animation speed by setting the property CGFloat animationSpeed before presenting the modal view controller The default value is 0.30

You can also customize the scaling of the parent controller view when the modal view is presented. It will affect the recoil effect. For that modify the property CGFloat parentViewScaling the default value is 0.80.

Also by default when you tap on the parent view when the modal is not presented full screen it will close it, you can turn it off by setting tapParentViewToClose to NO.

If you rootViewController view have a navigation bar you'll be able to drag the navigation bar if dragRootViewNavigationBar is set to YES (by default it is set to YES). Work only when the modal view is not presented full screen.

There are some other properties for you to play with.

The example provide sliders on the UI to better understand the effect of each property. Just run it in the simulator :)
