CWPopup Category

CWPopup is a category on UIViewController that allows you to easily make popup view controllers.

Fade

Fade View

Blur

Blur View

Installation

CocoaPods

pod 'CWPopup', '~> 1.2.4'

Manual

Import the directory CWPopup into your project. It contains the UIViewController categories.

Requirements

  • ARC
  • iOS 4.3

Usage

First of all, import the category.

#import "UIViewController+CWPopup.h"

You can choose to use either a fade background or a blurred background. The fade background will partially fade out the background, whereas the blurred background will apply a blur to the background. Note: No background animations will show if you use the blurred background as it is a static image placed on top of the view. The default setting is to use the fade background. To enable the blurred background, in your viewDidLoad function, add the following line of code:

self.useBlurForPopup = YES;

NOTE: Blur is only available in iOS 7+.

To present a view controller:

SamplePopupViewController *samplePopupViewController = [[SamplePopupViewController alloc] initWithNibName:@"SamplePopupViewController" bundle:nil];
[self presentPopupViewController:samplePopupViewController animated:YES completion:nil];

To dismiss a view controller:

if (self.popupViewController != nil) {
    [self dismissPopupViewControllerAnimated:YES completion:nil];
}

That's all there is to it.

Note: The background is not faded out if animated is set to NO - that way, if you want to implement your own animation and fading, you can.
