View Controller transitions

Features

  • PKAlertController has the title and description label, and you can set a text alignment.
  • Made with UIViewController-based, so that you can call it as the modal view controller, or add it to some view controller.
  • There are many cutom view controller transitions.
  • There are some layout styles, and it is the style of the size about the same as a UIAlertview, the flexible size and the fullscreen size.
  • To customize UI Color theme, use the class that inherited PKAlertDefaultTheme.
  • The view content is customizable to set a custom view same as a titleView of UINavigationItem.

Usage

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

Requirements

  • Supported build target – iOS 8.2 (Xcode 6.2, Apple LLVM compiler 6.0)
  • supported deployment target – iOS 7.1

Installation

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

pod "PKAlertController"

Components

  • PKAlertViewController – The root view controller of an alert.
  • PKAlertAction – This object represents an action that can be taken when tapping a button in an alert, and like a UIAlertAction.
  • PKAlertControllerConfiguration – An object defines the behavior of an alert.
  • PKAlertThemeManager – An object that manage the UI Color theme.

Examples

Import

Use by including the following import:

#import <PKAlertController.h>

Getting started

// Import this library.
#import <PKAlertController.h>

// Instantiate and configure a simple alert view controller with ok button.
PKAlertViewController *alertViewController = [PKAlertViewController simpleAlertControllerWithConfigurationBlock:^(PKAlertControllerConfiguration *configuration) {
    configuration.title = @"Alert title";
    configuration.message = @"Alert message";
    configuration.preferredStyle = PKAlertControllerStyleAlert;
    configuration.tintAdjustmentMode = UIViewTintAdjustmentModeDimmed; // Dimmed view's tint color.
}];

// Call present view controller as modal view controller goes with custom view controller transitional animation.
[self presentViewController:alertViewController animated:YES completion:nil];

Text alignment

To set the text alignment of title and message in a alert:

PKAlertViewController *alertViewConroller = [PKAlertViewController simpleAlertControllerWithConfigurationBlock:^(PKAlertControllerConfiguration *configuration) {
    configuration.title = @"Alert title";
    configuration.message = @"Alert message";
    configuration.titleTextAlignment = NSTextAlignmentLeft;
    configuration.messageTextAlignment = NSTextAlignmentLeft;
    configuration.tintAdjustmentMode = UIViewTintAdjustmentModeDimmed;
}];

Action button


// Add common actions.
NSMutableArray *actions = [NSMutableArray array];
[actions addObject:[PKAlertAction cancelAction]];
[actions addObject:[PKAlertAction okActionWithHandler:^(PKAlertAction *action, BOOL closed) {
    if (closed) {
        NSLog(@"Dismmied the PKAlertViewController!");
    } else {
        NSLog(@"Tap the ok button!");
    }
}]];
// Add a custom action.
[actions addObject:[PKAlertAction actionWithTitle:@"Close" handler:^(PKAlertAction *action, BOOL closed) {
    if (closed) {
        NSLog(@"Dismmied the PKAlertViewController!");
    } else {
        NSLog(@"Tap the close button!");
    }
}]];

PKAlertViewController *alertViewConroller = [PKAlertViewController simpleAlertControllerWithConfigurationBlock:^(PKAlertControllerConfiguration *configuration) {
    configuration.message = @"Alert message";
    // Set to the alert configuration.
    [configuration addActions:actions];
}];

Custom view

// Create a custom view
UINib *nib = [UINib nibWithNibName:NSStringFromClass([PKCustomView class]) bundle:[NSBundle mainBundle]];
PKCustomView *customView = [[nib instantiateWithOwner:nil options:nil] firstObject];

// Set the custom view
PKAlertViewController *alertViewConroller = [PKAlertViewController simpleAlertControllerWithConfigurationBlock:^(PKAlertControllerConfiguration *configuration) {
    configuration.customView = customView;
}];

And if you implement PKAlertViewLayoutAdapter in the custom view, will get an oppotunity to apply something to PKAlertViewController view components.

#pragma mark - <PKAlertViewLayoutAdapter>

- (void)applyLayoutWithAlertComponentViews:(NSDictionary *)views {
    // apply autolayouts to a PKAlertViewController's component.
    // contained views in views
    // key = `PKAlertRootViewKey`, value = PKAlertViewController's root view.
    // key = `PKAlertContentViewKey`, value = PKAlertViewController's content container view.
    // key = `PKAlertScrollViewKey`, value = PKAlertViewController's content scroll view.
    // key = `PKAlertTopLayoutGuideKey`, value = Top layout guide object.
    UIView *contentView = PKAlertGetViewInViews(PKAlertContentViewKey, views);

    NSMutableArray *contentConstraints = @[
        [NSLayoutConstraint constraintWithItem:self.headerImageView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationLessThanOrEqual toItem:
         contentView attribute:NSLayoutAttributeTop multiplier:1 constant:0],
    ].mutableCopy;
    NSLayoutConstraint *constraint = [NSLayoutConstraint constraintWithItem:self.headerImageView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:contentView attribute:NSLayoutAttributeTop multiplier:1 constant:0];
    constraint.priority = UILayoutPriorityDefaultHigh;
    [contentConstraints addObject:constraint];
    [contentView addConstraints:contentConstraints];

}

- (void)visibleSizeInAlertView {
    // Adjust visible size in alert view.
    CGSize size = self.layoutSize;
    size.height -= 44;
    return size;
}

PreferredStyle

The style of PKAlertViewControler. See the example project to use the style.

typedef NS_ENUM (NSInteger, PKAlertControllerStyle) {
    PKAlertControllerStyleAlert = 0,        // Normal style that the size about same as the size of UIAlertView.
    PKAlertControllerStyleFlexibleAlert,    // A style of flexible size.
    PKAlertControllerStyleFullScreen,       // A style of full screen.
};

If you use a style of full screen and push it to a navigation controller, Write the following code:

// Create a PKAlertViewController
PKAlertViewController *viewController = [PKAlertViewController instantiateOwnerViewController];

// Create a custom view
UINib *nib = [UINib nibWithNibName:NSStringFromClass([PKCustomView class]) bundle:[NSBundle mainBundle]];
PKCustomView *customView = [[nib instantiateWithOwner:nil options:nil] firstObject];

// Configure behavier
PKAlertControllerConfiguration *configuration = viewController.configuration;
configuration.customView = customView;
configuration.preferredStyle = PKAlertControllerStyleFullScreen;    // Set the full screen style.
configuration.statusBarAppearanceUpdate = NO;   // Prevent the status bar appearance updating.
viewController.view.frame = CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.bounds));
viewController.title = @"Full screen style";

// Push alert to a navigation controller.
[self.navigationController pushViewController:viewController animated:YES];

Custom view controller presenting/dismissing transition animation.

To use the animation style, the following code:

// Set the custom view
PKAlertViewController *alertViewConroller = [PKAlertViewController simpleAlertControllerWithConfigurationBlock:^(PKAlertControllerConfiguration *configuration) {
    // Set the presenting transition style
    configuration.presentationTransitionStyle = PKAlertControllerPresentationTransitionStyleScale;
    // Set the dismissing transition style
    configuration.dismissTransitionStyle = PKAlertControllerDismissStyleTransitionZoomOut;
}];

Change PKAlert view’s tintAdjustmentMode

// Set the custom view
PKAlertViewController *alertViewConroller = [PKAlertViewController simpleAlertControllerWithConfigurationBlock:^(PKAlertControllerConfiguration *configuration) {
    configuration.tintAdjustmentMode = UIViewTintAdjustmentModeAutomatic;   // Default: UIViewTintAdjustmentModeDimmed;
}];

PKAlertAction

The action button convenience constructor, one of the following:

+ (instancetype)actionWithTitle:(NSString *)title handler:(PKActionHandler)handler;
+ (instancetype)cancelAction;
+ (instancetype)cancelActionWithHandler:(void(^)(PKAlertAction *action, BOOL closed))handler;
+ (instancetype)okAction;
+ (instancetype)okActionWithHandler:(void(^)(PKAlertAction *action, BOOL closed))handler;
+ (instancetype)doneAction;
+ (instancetype)doneActionWithHandler:(void(^)(PKAlertAction *action, BOOL closed))handler;

PKAlertViewController

The alert view controller convenience constructor, one of the following:

+ (instancetype)instantiateOwnerViewController;
+ (instancetype)alertControllerWithConfigurationBlock:(PKAlertControllerConfigurationBlock)configurationBlock;
+ (instancetype)simpleAlertControllerWithConfigurationBlock:(PKAlertControllerConfigurationBlock)configurationBlock;
+ (instancetype)alertControllerWithConfiguration:(PKAlertControllerConfiguration *)configuration;

If you like procedural wrinting:

PKAlertControllerConfiguration *configuration = [[PKAlertControllerConfiguration alloc] init];
configuration.message = @"Alert message";
configuration.actionControlHeight = 60;
[configuration addAction:[PKAlertAction cancelAction]];

PKAlertViewController *viewController = [PKAlertViewController alertControllerWithConfiguration:configuration];

Or the builder design pattern:

PKAlertViewController *viewController = [PKAlertViewController alertControllerWithConfigurationBlock:^(PKAlertControllerConfiguration *configuration) {
    configuration.message = @"Alert message";
    configuration.actionControlHeight = 60;
    [configuration addAction:[PKAlertAction cancelAction]];
}];
