HWPopController is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'HWPopController', '~> 1.0.5'

How to use

  1. Create you popup UIViewController.

    1. import HWPopController framework
    2. config contentSizeInPop and contentSizeInPopWhenLandscape(if you want to support landscape)
    #import "HWPop1ViewController.h"
    #import <HWPopController/HWPop.h>
    @interface HWPop1ViewController ()
    @implementation HWPop1ViewController
    - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view.
        self.contentSizeInPop = CGSizeMake(250, 300);
        self.contentSizeInPopWhenLandscape = CGSizeMake(300, 200);
        // build you pop view.
  2. Popup your viewController

    If you want high custom your popup, init HWPopController. Then config the properties what you want. Please see HWPopController.h

        HWPop1ViewController *pop1ViewController = [HWPop1ViewController new];
        HWPopController *popController = [[HWPopController alloc] initWithRootViewController:pop1ViewController];
        // popView position
        popController.popPosition = HWPopPositionTop;
        [popController presentInViewController:self];

    Quick popup, use the UIViewController category.

    HWPop1ViewController *pop1ViewController = [HWPop1ViewController new];
    [pop1ViewController popupWithPopType:HWPopTypeGrowIn dismissType:HWDismissTypeGrowOut dismissOnBackgroundTouch:YES];
  3. Dismiss pop Use native api.

    [self dismissViewControllerAnimated:YES completion:^{

    Get popController, then call popController dismiss api.

     [self.popController dismiss];

Pop UINavigationController

If you want pop UINavigationController, and every stacked UIViewController contentSize is not same. You can use HWPopNavigationController.

HWPopNavigationController subclass UINavigationController, you can inherit from HWPopNavigationController, config contentSizeInPop as default contentSize.

When you push A Controller, then Push B Controller. A, B Controller should config contentSizeInPop if you need. If you have not config it, we will use NavigationController contentSizeInPop.


  • UINavigationController
    • HWPopNavigationController
      • Your custom UINavigationController inherit from HWPopNavigationController

More details, pls see the Example.


To run the example project, clone the repo, and run pod install from the Example directory first.
