解决写聊天时候输入框和cell的问题

ZCMessageToolBar

解决写聊天时候输入框和cell的问题 包含语音\图片\定位\文字\表情的一系列封装,实现了一句话调用 toolBar=[[ZCMessageToolBar alloc]initWithBlock:^(NSString *sign, NSString *message) { NSLog(@"%@~~%@",sign,message);

   MessageModel*model=[[MessageModel alloc]init];
   model.body=[NSString stringWithFormat:@"%@%@",sign,message];
   model.isOutgoing=YES;
   model.timestamp=[NSDate date];
   [self.dataArray addObject:model];
   [_tableView reloadData];
   
   [_tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:self.dataArray.count-1 inSection:0] atScrollPosition:UITableViewScrollPositionBottom animated:YES];
   
   
   //每一次进行自动回复这次所发送的内容
   [self performSelector:@selector(backMessage) withObject:nil afterDelay:1];
}];
[self.view addSubview:toolBar];

- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"chat_bg_default"]];
/*
需要加上支持http和定位NSLocationWhenInUseUsageDescription
本工程主要是2个类
 ZCFaceToolBar和MessageCell这2个类
 所依赖相关库的支持,包含以下
 BQMM  表情
 VoiceContvert 语音
