ChatMessageTableViewController is like iMessage app. support text && image . ![Messages Screenshot 1][img1] ![Messages Screenshot 2][img2] This messages tableview controller is very similar to the one in the iOS Messages app. **Note, this is only a messaging UI, not a messaging app.** This is intended to be used in an existing app where you have (or are developing) a messaging system and need a user interface for it. **See more [screenshots][link1] in the `Screenshots/` directory. (Surprise!)** ## About This is based on work by [@soffes](http://github.com/soffes) [SSMessagingViewController][ss]. I developed this to use in [Hemoglobe](http://www.hemoglobe.com) for private messages between users. [Square message bubbles]([img4]) designed by [@michaelschultz](http://www.twitter.com/michaelschultz). ## Features * Up-to-date for iOS 6.0 and ARC (iOS 5.0+ required) * Universal for iPhone * Allows arbitrary message (and bubble) sizes * Copy & paste text message && Save image message * Timestamp options * Swipe/pull down to hide keyboard * Dynamically resizes input text view as you type * Smooth hiding/showing keyboard animations with `NSNotification` * Automatically enables/disables send button if text view is empty or not * Smooth send animations * Send/Receive sound effects * Various bubble styles ### From source * Drag the `JSMessagesTableViewController/` folder to your project. * Add the `AudioToolbox.framework` to your project, if you want to use the sound effects ## How To Use #####Subclass `JSMessagesViewController` * In `- (void)viewDidLoad` * Set your view controller as the `delegate` and `datasource` * Set your view controller `title` #####Implement the `JSMessagesViewDelegate` protocol ````objective-c - (void)sendPressed:(UIButton *)sender withText:(NSString *)text ```` * Hook into your own backend here * Call `[self finishSend]` at the end of this method to animate and reset the text input view * Optionally play sound effects * For outgoing messages `[JSMessageSoundEffect playMessageSentSound]` * For incoming messages `[JSMessageSoundEffect playMessageReceivedSound]` ````objective-c - (JSBubbleMessageType)messageTypeForRowAtIndexPath:(NSIndexPath *)indexPath ```` * The type of bubble for this row, options are: * `JSBubbleMessageTypeIncoming` * `JSBubbleMessageTypeOutgoing` * The type of Message for this row, options are: * `JSBubbleMediaTypeText` * `JSBubbleMediaTypeImage` ````objective-c - (JSBubbleMediaType)messageMediaTypeForRowAtIndexPath:(NSIndexPath *)indexPath ```` * The [style of the bubble][link1] for this row, options are: * `JSBubbleMessageStyleDefault` * `JSBubbleMessageStyleSquare` * `JSBubbleMessageStyleDefaultGreen` ````objective-c - (JSMessagesViewTimestampPolicy)timestampPolicy ```` * How/when to display timestamps for messages, options are: * `JSMessagesViewTimestampPolicyAll` * `JSMessagesViewTimestampPolicyAlternating` * `JSMessagesViewTimestampPolicyEveryThree` * `JSMessagesViewTimestampPolicyEveryFive` * `JSMessagesViewTimestampPolicyCustom` ````objective-c - (JSMessagesViewAvatarPolicy)avatarPolicy ```` * How/when to display avatars, options are: * `JSMessagesViewAvatarPolicyIncomingOnly` * `JSMessagesViewAvatarPolicyBoth` * `JSMessagesViewAvatarPolicyNone` ````objective-c - (JSAvatarStyle)avatarStyle ```` * The [style for the avatars][link1], options are: * `JSAvatarStyleCircle` * `JSAvatarStyleSquare` * `JSAvatarStyleNone` ````objective-c - (BOOL)hasTimestampForRowAtIndexPath:(NSIndexPath *)indexPath ```` * Returns if this row should display a timestamp or not * Required only if using `JSMessagesViewTimestampPolicyCustom` #####Implement the `JSMessagesViewDataSource` protocol ````objective-c - (NSString *)textForRowAtIndexPath:(NSIndexPath *)indexPath ```` * The text to be displayed for this row ````objective-c - (NSDate *)timestampForRowAtIndexPath:(NSIndexPath *)indexPath ```` * The timestamp to be displayed *above* this row ````objective-c - (UIImage *)avatarImageForIncomingMessage ```` * The avatar image for incoming messages ````objective-c - (UIImage *)avatarImageForOutgoingMessage ```` * The avatar image for outgoing messages #####Implement the [table view data source][ref1] method that you should be familiar with ````objective-c - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section ```` #####Customize * For custom background color, use `- (void)setBackgroundColor:(UIColor *)color` * For custom send button, override `- (UIButton *)sendButton` ##### Notes * You may present view programmatically, or use Storyboards * Your `JSMessagesViewController` subclass **must** be presented in a `UINavigationController` ##### Demo projects included * `MessagesDemo.xcodeproj` for example of programmatic presentation * `MessagesDemoStoryboards/MessagesDemoSB.xcodeproj` for example of use with Storyboards ## Apps Using This Control [Hemoglobe](http://bit.ly/hemoglobeapp) [FourChat](https://itunes.apple.com/us/app/fourchat/id650833730?mt=8) [Libraries for developers](https://itunes.apple.com/us/app/libraries-for-developers/id653427112?mt=8) [jessesquires 's MessagesTableViewController](https://github.com/jessesquires/MessagesTableViewController) *[Contact me](mailto:1933549736@qq.com) to have your app listed here.* ## Related Projects [SSMessagingViewController][ss] [AcaniChat](https://github.com/acani/AcaniChat) ## [MIT License](http://opensource.org/licenses/MIT) You are free to use this as you please.
