DMCustomModalViewController
===========================
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.

###Cocoapods

Add `pod DMCustomModalViewController` to your podfile

###Run the example and install it manually

Run `pod install`in 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.h`where 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

![image](https://raw.github.com/Dimillian/DMCustomModalViewController/master/screen1.png)

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 :)
