Works like UIPopoverController

---

passthroughViews

An array of views that the user can interact with while the popover is visible.

wantsDefaultContentAppearance

Determines whether the default content appearance should be used for the popover.

popoverLayoutMargins

The margins that define the portion of the screen in which it is permissible to display the popover.

Works also with blocks

---

A block object can be executed when animation sequences ends. This parameter may be nil.

Important : If a block object is defined then correspondent delegate methods is not called.

Example

popover = [[WYPopoverController alloc] initWithContentViewController:contentViewController];
[popover presentPopoverAsDialogAnimated:YES
                             completion:^{
                                 // Code executed after popover presentation animation sequence ends
                             }];

Animation options

---

There are 3 styles of animation :

• Fade (by default)
• Scale
• Fade with Scale

Example

popover = [[WYPopoverController alloc] initWithContentViewController:contentViewController];
[popover presentPopoverFromRect:btn.bounds
                         inView:btn
       permittedArrowDirections:WYPopoverArrowDirectionAny
                       animated:YES
                        options:WYPopoverAnimationOptionFadeWithScale];

ARC

---

WYPopoverController uses ARC.

Installation

---

iOS SDK 7.0 (with Xcode 5) is required.

Cocoapods

Add this line pod 'WYPopoverController', '~> 0.2.0' to your PodFile.

Your PodFile should look like :

platform :ios, '6.0'
pod 'WYPopoverController', '~> 0.2.2'

To use the master branch of the repo :

platform :ios, '6.0'
pod 'WYPopoverController', :git => 'https://github.com/nicolaschengdev/WYPopoverController.git'

Manually

Add these files to your project :

• WYPopoverController.h and WYPopoverController.m
• WYStoryboardPopoverSegue.h and WYStoryboardPopoverSegue.m

And link QuartzCore.framework library in the Build Phases of your project targets.

Examples

---

Simple

In the implementation of your view controller

// YourViewController.m

@interface YourViewController () <WYPopoverControllerDelegate>
{
    WYPopoverController* popoverController;
}

- (IBAction)showPopover:(id)sender;

@end

@implementation YourViewController

- (IBAction)showPopover:(id)sender
{
	popoverController = [[WYPopoverController alloc] initWithContentViewController:controller];
    popoverController.delegate = self;
    [popoverController presentPopoverFromRect:button.bounds inView:button permittedArrowDirections:WYPopoverArrowDirectionAny animated:YES];
}

- (BOOL)popoverControllerShouldDismissPopover:(WYPopoverController *)controller
{
    return YES;
}

- (void)popoverControllerDidDismissPopover:(WYPopoverController *)controller
{
    popoverController.delegate = nil;
    popoverController = nil;
}

@end

Appearance (Tint Color)

[WYPopoverController setDefaultTheme:[WYPopoverTheme theme]];

WYPopoverBackgroundView *appearance = [WYPopoverBackgroundView appearance];
[appearance setTintColor:[UIColor orangeColor]];

Appearance (Flat Popover)

UIColor *greenColor = [UIColor colorWithRed:26.f/255.f green:188.f/255.f blue:156.f/255.f alpha:1];

[WYPopoverController setDefaultTheme:[WYPopoverTheme theme]];

WYPopoverBackgroundView *popoverAppearance = [WYPopoverBackgroundView appearance];
        
[popoverAppearance setOuterCornerRadius:4];
[popoverAppearance setOuterShadowBlurRadius:0];
[popoverAppearance setOuterShadowColor:[UIColor clearColor]];
[popoverAppearance setOuterShadowOffset:CGSizeMake(0, 0)];
        
[popoverAppearance setGlossShadowColor:[UIColor clearColor]];
[popoverAppearance setGlossShadowOffset:CGSizeMake(0, 0)];
        
[popoverAppearance setBorderWidth:8];
[popoverAppearance setArrowHeight:10];
[popoverAppearance setArrowBase:20];
        
[popoverAppearance setInnerCornerRadius:4];
[popoverAppearance setInnerShadowBlurRadius:0];
[popoverAppearance setInnerShadowColor:[UIColor clearColor]];
[popoverAppearance setInnerShadowOffset:CGSizeMake(0, 0)];
        
[popoverAppearance setFillTopColor:greenColor];
[popoverAppearance setFillBottomColor:greenColor];
[popoverAppearance setOuterStrokeColor:greenColor];
[popoverAppearance setInnerStrokeColor:greenColor];
        
UINavigationBar* navBarInPopoverAppearance = [UINavigationBar appearanceWhenContainedIn:[UINavigationController class], [WYPopoverController class], nil];
[navBarInPopoverAppearance setTitleTextAttributes: @{
                  UITextAttributeTextColor : [UIColor whiteColor],
            UITextAttributeTextShadowColor : [UIColor clearColor],
           UITextAttributeTextShadowOffset : [NSValue valueWithUIOffset:UIOffsetMake(0, -1)]}];

Storyboard

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
	if ([segue.identifier isEqualToString:@"[YOUR_SEGUE_IDENTIFIER]"])
	{
		WYStoryboardPopoverSegue* popoverSegue = (WYStoryboardPopoverSegue*)segue;

		UIViewController* destinationViewController = (UIViewController *)segue.destinationViewController;
        destinationViewController.contentSizeForViewInPopover = CGSizeMake(280, 280);		// Deprecated in iOS7. Use 'preferredContentSize' instead.

        popoverController = [popoverSegue popoverControllerWithSender:sender permittedArrowDirections:WYPopoverArrowDirectionAny animated:YES];
        popoverController.delegate = self;
	}
}

Theme

Introduced in 0.2.1 release, you can change appearance of your popovers with themes.

- (void)changePopoverTheme
{
    popover.theme = [WYPopoverTheme themeForIOS6];  // you set a new theme

    // use beginThemeUpdates and endThemeUpdates methods if you have to change several values which compose your current theme
    
    [popover beginThemeUpdates];
        popover.theme.arrowHeight = 30;
        popover.theme.arrowBase = 40;
    [popover endThemeUpdates];
}

Keyboard

By default, when keyboard is shown, popover will be repositionned if it is (partially) hidden. Introduced in 0.2.1 release, you can control value of y offset when keyboard is shown with the following delegate method :

- (void)popoverController:(WYPopoverController *)popoverController willTranslatePopoverWithYOffset:(CGFloat *)value
{
    *value = 0; // if value is setted to 0 then popover will not be translated
}

Handling popover controllers during orientation changes

---

When showing a popover controller, there are times when you will need to handle how the popover controller appears after a change in device orientation.

Situations when handling is required:

• If the popover controller is presented from a target rectangle using the -presentPopoverFromRect:inView:permittedArrowDirections:animated method of WYPopoverController. You can use -popoverController:willRepositionPopoverToRect:inView: method introduced in the 0.1.6 release .
• If the popover controller is presented from a bar button item that is removed after the rotation has finished .
