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;
}
