UBInput

1.属性加初始化 @property (nonatomic,strong) DDInput *input;

• (DDInput *)input { if (!_input) { _input = [[DDInput alloc]initWithRootView:self.dataView]; } return _input; }

2.设置input的view（DDInputContainer 协议） DDWatchLiveInputContainer *container = [[DDWatchLiveInputContainer alloc]init]; [self.input setContainer:container]; self.input.minToolbarBottomDistance = iPhoneX ? 25 : 5;

3.设置遮罩 //遮罩的背景View（全屏） UIView *bgView = [[UIView alloc]initWithFrame:CGRectZero]; bgView.backgroundColor = UIColorHexA(0x000000, 0.5);

[self.input setBackgroundView:bgView];

4.回调

//是否允许改变 self.input.shouldChangeText = ^BOOL(NSRange range, NSString *replacementText) { return YES; };

//即将发送（键盘上Done按钮） self.input.willSendMessageText = ^(NSString *text) {

//TODO: send message

[weakSelf.input done];
