# QMChatViewController is deprecated and won't be supported. [](https://cocoapods.org/pods/QMChatViewController) [](https://cocoapods.org/pods/QMChatViewController) [](https://cocoapods.org/pods/QMChatViewController) An elegant ready-to-go chat view controller for `iOS` chat applications that use `Quickblox communication backend`. #Features - Ready-to-go chat view controller with a set of cells. - Automatic cell size calculation. - UI customization for chat cells. - Flexibility in improving and extending functionality. - Easy to connect with `Quickblox`. - Optimized and performant. - Supports portrait and landscape orientations. - Auto Layout inside. # Screenshots # Requirements - iOS 8.0+ - ARC - Xcode 6+ - Quickblox SDK 2.0+ - TTTAttributedLabel - SDWebImage # Installation ## CocoaPods pod 'QMChatViewController' ## Manually * Drag` QMChatViewController` folder to your project folder and link to the appropriate target. * Install dependencies. # Dependencies - [TTTAttributedLabel](https://github.com/TTTAttributedLabel/TTTAttributedLabel) - [SDWebImage](https://github.com/rs/SDWebImage) - [Quickblox iOS SDK v2.0+](https://github.com/QuickBlox/quickblox-ios-sdk/archive/master.zip) # Getting started An example is included in the repository. Try it out to see how chat view controller works. Steps to add `QMChatViewController` to Your app: 1. Create a subclass of `QMChatViewController`. You could create it both from code and Interface Builder. 2. Open your subclass of `QMChatViewController` and do the following in *viewDidLoad* method: * Configure chat sender ID and display name: ```objective-c self.senderID = 2000; self.senderDisplayName = @"user1"; ``` * Insert messages using corresponding methods: ````objective-c [self.chatDataSource addMessages:]; ```` 3. Handle message sending. ```objective-c - (void)didPressSendButton:(UIButton *)button withMessageText:(NSString *)text senderId:(NSUInteger)senderId senderDisplayName:(NSString *)senderDisplayName date:(NSDate *)date { // Add sending message - for example: QBChatMessage *message = [QBChatMessage message]; message.text = text; message.senderID = senderId; QBChatAttachment *attacment = [[QBChatAttachment alloc] init]; message.attachments = @[attacment]; [self.chatDataSource addMessage:message]; [self finishSendingMessageAnimated:YES]; // Save message to your cache/memory storage. // Send message using Quickblox SDK } ``` 4. Return cell view classes specific to chat message: ```objective-c - (Class)viewClassForItem:(QBChatMessage *)item { // Cell class for message if (item.senderID != self.senderID) { return [QMChatIncomingCell class]; } else { return [QMChatOutgoingCell class]; } return nil; } ``` 5. Calculate size of cell and minimum width: ```objective-c - (CGFloat)collectionView:(QMChatCollectionView *)collectionView minWidthAtIndexPath:(NSIndexPath *)indexPath { QBChatMessage *item = [self.chatDataSource messageForIndexPath:indexPath]; NSAttributedString *attributedString = item.senderID == self.senderID ? [self bottomLabelAttributedStringForItem:item] : [self topLabelAttributedStringForItem:item]; CGSize size = [TTTAttributedLabel sizeThatFitsAttributedString:attributedString withConstraints:CGSizeMake(1000, 10000) limitedToNumberOfLines:1]; return size.width; } ``` 6. Top, bottom and text labels. ```objective-c - (NSAttributedString *)attributedStringForItem:(QBChatMessage *)messageItem { UIColor *textColor = [messageItem senderID] == self.senderID ? [UIColor whiteColor] : [UIColor colorWithWhite:0.290 alpha:1.000]; UIFont *font = [UIFont fontWithName:@"Helvetica" size:15]; NSDictionary *attributes = @{NSForegroundColorAttributeName:textColor, NSFontAttributeName:font}; NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:messageItem.text attributes:attributes]; return attrStr; } - (NSAttributedString *)topLabelAttributedStringForItem:(QBChatMessage *)messageItem { if (messageItem.senderID == self.senderID) { return nil; } UIFont *font = [UIFont fontWithName:@"Helvetica" size:14]; UIColor *textColor = [UIColor colorWithRed:0.184 green:0.467 blue:0.733 alpha:1.000]; NSDictionary *attributes = @{NSForegroundColorAttributeName:textColor, NSFontAttributeName:font}; NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:@"nickname" attributes:attributes]; return attrStr; } - (NSAttributedString *)bottomLabelAttributedStringForItem:(QBChatMessage *)messageItem { UIFont *font = [UIFont fontWithName:@"Helvetica" size:12]; UIColor *textColor = [messageItem senderID] == self.senderID ? [UIColor colorWithWhite:1.000 alpha:0.510] : [UIColor colorWithWhite:0.000 alpha:0.490]; NSDictionary *attributes = @{NSForegroundColorAttributeName:textColor, NSFontAttributeName:font}; NSString *dateStr = @"10:20"; NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:dateStr attributes:attributes]; return attrStr; } ``` 7. Modifying collection chat cell attributes without changing constraints: ```objective-c struct QMChatLayoutModel { CGSize avatarSize; CGSize containerSize; UIEdgeInsets containerInsets; CGFloat topLabelHeight; CGFloat bottomLabelHeight; CGSize staticContainerSize; CGFloat maxWidthMarginSpace; }; typedef struct QMChatLayoutModel QMChatCellLayoutModel; ``` * size of the avatar image view * message view container size * top label height * bottom label height * static size of container view * margin space between message and screen end You can modify this attributes in this method: ````objective-c - (QMChatCellLayoutModel)collectionView:(QMChatCollectionView *)collectionView layoutModelAtIndexPath:(NSIndexPath *)indexPath { QMChatCellLayoutModel layoutModel = [super collectionView:collectionView layoutModelAtIndexPath:indexPath]; //Update attributes here ... return layoutModel; } ```` So if you want to hide top label or bottom label you just need to set their height to 0. ## Attachments `QMChatViewController` supports image attachment cell messages. `QMChatAttachmentIncomingCell` is used for incoming attachments, `QMChatAttachmentOutgoingCell` is used for outgoing attachments. Both of them have progress label to display loading progress. XIB's are also included. ## Chat data source `QMChatViewController` contains its data source manager called `QMChatDataSource`. It has implementation of all methods, which you need to work with `QMChatViewController`. This class should be used to add, update and delete messages from data source. `QMChatDataSource` has delegate, which called whenever data source were modified. For more information on methods and its usage check out our inline doc in `QMChatDataSource.h`. # Questions & Help - You could create an issue on GitHub if you are experiencing any problems.
