STPopup

STPopup provides STPopupController, which works just like UINavigationController in popup style, for both iPhone and iPad.

Features:

• Extend your view controller from UIViewController, build it in your familiar way.
• Push/Pop view controller in to/out of popup view stack, and set navigation items by using self.navigationItem.leftBarButtonItem and rightBarButtonItem, just like you are using UINavigationController.
• Support both "Form Sheet" and "Bottom Sheet" style.
• Work well with storyboard(including segue).
• Customize UI by using UIAppearance.
• Fully customizable popup transition style.
• Auto-reposition of popup view when keyboard is showing up, make sure your UITextField/UITextView won't be covered by the keyboard.
• Drag navigation bar to dismiss popup view.
• Support both portrait and landscape orientation, and both iPhone and iPad.

Overview

Used in Sth4Me app

Get Started

CocoaPods

platform :ios, '7.0'
pod 'STPopup'

Carthage

github "kevin0571/STPopup"

Import header file

#import <STPopup/STPopup.h>

Initialize STPopupController

STPopupController *popupController = [[STPopupController alloc] initWithRootViewController:[ViewController new]];
[popupController presentInViewController:self];

Set content size in view controller

@implementation ViewController

- (instancetype)init
{
    if (self = [super init]) {
        self.title = @"View Controller";
        self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStylePlain target:self action:@selector(nextBtnDidTap)];
        self.contentSizeInPopup = CGSizeMake(300, 400);
        self.landscapeContentSizeInPopup = CGSizeMake(400, 200);
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Add views here
    // self.view.frame.size == self.contentSizeInPopup in portrait
    // self.view.frame.size == self.landscapeContentSizeInPopup in landscape
}

@end

Push, pop and dismiss view controllers

[self.popupController pushViewController:[ViewController new] animated:YES];
[self.popupController popViewControllerAnimated:YES]; // Popup will be dismissed if there is only one view controller in the popup view controller stack
[self.popupController dismiss];

Bottom sheet style

STPopupController *popupController = [[STPopupController alloc] initWithRootViewController:[ViewController new]];
popupController.style = STPopupStyleBottomSheet;
[popupController presentInViewController:self];

Customize popup transition style

#pragma mark - STPopupControllerTransitioning

- (NSTimeInterval)popupControllerTransitionDuration:(STPopupControllerTransitioningContext *)context
{
    return context.action == STPopupControllerTransitioningActionPresent ? 0.5 : 0.35;
}

- (void)popupControllerAnimateTransition:(STPopupControllerTransitioningContext *)context completion:(void (^)())completion
{
    UIView *containerView = context.containerView;
    if (context.action == STPopupControllerTransitioningActionPresent) {
        containerView.transform = CGAffineTransformMakeTranslation(containerView.superview.bounds.size.width - containerView.frame.origin.x, 0);
        
        [UIView animateWithDuration:[self popupControllerTransitionDuration:context] delay:0 usingSpringWithDamping:1 initialSpringVelocity:1 options:UIViewAnimationOptionCurveEaseInOut animations:^{
            context.containerView.transform = CGAffineTransformIdentity;
        } completion:^(BOOL finished) {
            completion();
        }];
    }
    else {
        [UIView animateWithDuration:[self popupControllerTransitionDuration:context] delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
            containerView.transform = CGAffineTransformMakeTranslation(- 2 * (containerView.superview.bounds.size.width - containerView.frame.origin.x), 0);
        } completion:^(BOOL finished) {
            containerView.transform = CGAffineTransformIdentity;
            completion();
        }];
    }
}

Blur background

STPopupController *popupController = [[STPopupController alloc] initWithRootViewController:[PopupViewController1 new]];
if (NSClassFromString(@"UIBlurEffect")) {
    UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
    popupController.backgroundView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
}

Dismiss by tapping background

popupController = [[STPopupController alloc] initWithRootViewController:self];
[popupController.backgroundView addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(backgroundViewDidTap)]];

Customize UI

[STPopupNavigationBar appearance].barTintColor = [UIColor colorWithRed:0.20 green:0.60 blue:0.86 alpha:1.0];
[STPopupNavigationBar appearance].tintColor = [UIColor whiteColor];
[STPopupNavigationBar appearance].barStyle = UIBarStyleDefault;
[STPopupNavigationBar appearance].titleTextAttributes = @{ NSFontAttributeName: [UIFont fontWithName:@"Cochin" size:18], NSForegroundColorAttributeName: [UIColor whiteColor] };
    
[[UIBarButtonItem appearanceWhenContainedIn:[STPopupNavigationBar class], nil] setTitleTextAttributes:@{ NSFontAttributeName:[UIFont fontWithName:@"Cochin" size:17] } forState:UIControlStateNormal];
