作者liuxinixn，代码LXKeyBoardTextView-master。LXKeyBoardTextView是仿微信多行限制多行输入，一体键盘。 支持代码以及XIB. 介绍： typedef void (^SendBlock) (NSString *text); @interface LXKeyBoard : UIView /** 需要配置的属性（也可不传） */ @property(nonatomic,assign)BOOL isDisappear;//是否即将消失。 @property(nonatomic,assign)int maxLine;//设置最大行数 @property(nonatomic,assign)CGFloat topOrBottomEdge;//上下间距 @property(nonatomic,strong)UIFont *font;//设置字体大小(决定输入框的初始高度) //设置好属性之后开始布局 -(void)beginUpdateUI; //回调 @property(nonatomic,copy)SendBlock sendBlock; @end 使用方法： -(LXKeyBoard *)keyboard{ if (!_keyboard) { _keyboard =[[LXKeyBoard alloc]initWithFrame:CGRectZero]; _keyboard.backgroundColor =[UIColor whiteColor]; _keyboard.maxLine = 3; _keyboard.font = Font(18); _keyboard.topOrBottomEdge = 10; [_keyboard beginUpdateUI]; LXWS(weakSelf); _keyboard.sendBlock = ^(NSString *text) { NSLog(@"%@",text); weakSelf.resultLabel.text = text; [weakSelf.resultLabel sizeThatFits:CGSizeMake(Device_Width - 40, MAXFLOAT)]; }; } return _keyboard; } -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; self.keyboard.isDisappear = NO; } -(void)viewWillDisappear:(BOOL)animated{ [super viewWillDisappear:animated]; self.keyboard.isDisappear = YES; }
