ios中自定义键盘+回收

ios中自定义键盘+回收

//  自定义键盘

UIView *keyView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.window.frame.size.width, 256)];

field.inputView = keyView;

// 1、添加一个按钮

UIButton *keyBtn = [UIButton buttonWithType:UIButtonTypeSystem];

keyBtn.frame = CGRectMake(0, 0, 50, 40);

[keyBtn addTarget:self action:@selector(haha:)            forControlEvents:UIControlEventTouchUpInside];

[keyBtn setTitle:@"1" forState:UIControlStateNormal];

keyBtn.backgroundColor = [UIColor whiteColor];

[keyBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

[keyView addSubview:keyBtn];

// 1.1点击按钮，实现可以让按钮的标题显示在输入框中

- (void)haha: (UIButton *)sender{

//  得到输入框

UITextField  *fiel = (UITextField *)[self.window viewWithTag:2000];

// 得到按钮标题,因为标题是个字符串，所以得到的结果得让字符串承接

NSString *titel = [sender titleForState:UIControlStateNormal];

//    将标题显示在输入框中

//    fiel.text = titel;

//    拼接字符，也可以使用这种拼接的方式，来连续输入

fiel.text = [fiel.text stringByAppendingString:titel]；

}

//2、 添加一个回收键盘的按钮

初始化创建    UIButton *keyBtn1 = [UIButton buttonWithType:UIButtonTypeSystem];

设置大小 keyBtn1.frame = CGRectMake(100, 0, 50, 40);

添加关联方法  [keyBtn1 addTarget:self action:@selector(huishou:) forControlEvents:UIControlEventTouchUpInside];

设置标题 [keyBtn1 setTitle:@"Return" forState:UIControlStateNormal];

设置背景色  keyBtn1.backgroundColor = [UIColor whiteColor];

设置标题颜色 [keyBtn1 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

呈现  [keyView addSubview:keyBtn1];

//回收键盘的按钮实现方法

- (void)huishou:(UIButton *)sender{

得到textfield  UITextField  *fiel = (UITextField *)[self.window viewWithTag:2000];

//  回收键盘，取消输入框的第一响应者,结束输入框的编辑状态

[fiel resignFirstResponder];

}
