CRToast - Xamarin iOS Binding Library

CRToast is a library that allows you to easily create notifications that appear on top of or by pushing out the status bar or navigation bar. CRToast was originally based on CWStatusBarNotification.

Requirements

CRToast uses ARC and requires iOS 7.0+. Works for iPhone and iPad.

Installation

Nuget

  Install-Package Naxam.CRToast.iOS

Usage

Notifications can be created through CRToastManager's showNotificationWithOptions:completionBlock: This will queue up a notification with the options specified. You provide options for your notification in a dictionary using the keys in CRToast.h

Example

This code

NSDictionary *options = @{
                          kCRToastTextKey : @"Hello World!",
                          kCRToastTextAlignmentKey : @(NSTextAlignmentCenter),
                          kCRToastBackgroundColorKey : [UIColor redColor],
                          kCRToastAnimationInTypeKey : @(CRToastAnimationTypeGravity),
                          kCRToastAnimationOutTypeKey : @(CRToastAnimationTypeGravity),
                          kCRToastAnimationInDirectionKey : @(CRToastAnimationDirectionLeft),
                          kCRToastAnimationOutDirectionKey : @(CRToastAnimationDirectionRight)
                          };
[CRToastManager showNotificationWithOptions:options
                            completionBlock:^{
                                NSLog(@"Completed");
                            }];

Customization

CRToast is very customizable. Taking a hint from UIStringDrawing's drawInRect:withAttributes: book, notifications are created with dictionaries filled with all their options.

Customizing Appearance

CRToast allows for setting of

• Left aligned image

Title and Subtitle text with:

• Text Color
• Text Font
• Text Alignment
• Text Color
• Text Shadow Color
• Text Shadow Offset
• Text Max Number of Lines

Customizing Animation

CRToast also allows for animation customization. This includes.

• Animation Type (Linear, Spring or Gravity)
• Animation Physics Coefficients (Spring Damping, Spring Initial Velocity, Gravity Magnitude)
• Presentation Type (Slide over bars or push content out)
• Status visibility (Status bar on top or below)
• Direction (Enter and exit in any direction)
• Enter, Stay on Screen and Exit Timing

Touch Interactions

CRToast allows for any notification to respond to different types of touch interactions (tap, swipe). Interaction responders can be set as defaults or on a per notification basis. The types of interactions you can set up to respond to are:

CRToastInteractionTypeSwipeUp
CRToastInteractionTypeSwipeLeft
CRToastInteractionTypeSwipeDown
CRToastInteractionTypeSwipeRight
CRToastInteractionTypeTapOnce
CRToastInteractionTypeTapTwice
CRToastInteractionTypeTwoFingerTapOnce
CRToastInteractionTypeTwoFingerTapTwice

There are also wild card interaction types which cover a range of interactions

CRToastInteractionTypeSwipe
CRToastInteractionTypeTap
CRToastInteractionTypeAll

Any interaction can be responded to using a CRToastInteractionResponder, they can be made with the following constructor

+ (instancetype)interactionResponderWithInteractionType:(CRToastInteractionType)interactionType
                                   automaticallyDismiss:(BOOL)automaticallyDismiss
                                                  block:(void (^)(CRToastInteractionType interactionType))block;

You can set a collection of CRToastInteractionResponders as the object for the key kCRToastInteractionRespondersKey in defaults to have all notifications respond to a certain interaction, or on any given one to have the interaction responders just work for that one notification.

Persistent and Programmatically Dismissed Notifications

You can also dismiss the current notification at any time with

+ (void)dismissNotification:(BOOL)animated;

You can present notifications that must be dismissed by the user by passing @(DBL_MAX) for kCRToastTimeIntervalKey and setting up an interaction responder that will dismiss the notification.

Setting Defaults

There are sane defaults set for all properties, however you can set a default set of options for your application's notifications using CRToastManagers's setDefaultOptions:.
