ios中自定義鍵盤+回收

//? 自定義鍵盤

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

field.inputView = keyView;

// 1、添加一個按鈕

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點擊按鈕，實現(xiàn)可以讓按鈕的標題顯示在輸入框中

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

//? 得到輸入框

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

// 得到按鈕標題,因為標題是個字符串，所以得到的結(jié)果得讓字符串承接

NSString *titel = [sender titleForState:UIControlStateNormal];

//? ? 將標題顯示在輸入框中

//? ? fiel.text = titel;

//? ? 拼接字符，也可以使用這種拼接的方式，來連續(xù)輸入

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

}

//2、 添加一個回收鍵盤的按鈕

初始化創(chuàng)建? ? UIButton *keyBtn1 = [UIButton buttonWithType:UIButtonTypeSystem];

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

添加關(guān)聯(lián)方法? [keyBtn1 addTarget:self action:@selector(huishou:) forControlEvents:UIControlEventTouchUpInside];

設(shè)置標題 [keyBtn1 setTitle:@"Return" forState:UIControlStateNormal];

設(shè)置背景色? keyBtn1.backgroundColor = [UIColor whiteColor];

設(shè)置標題顏色 [keyBtn1 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

呈現(xiàn)? [keyView addSubview:keyBtn1];

//回收鍵盤的按鈕實現(xiàn)方法

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

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

//? 回收鍵盤，取消輸入框的第一響應(yīng)者,結(jié)束輸入框的編輯狀態(tài)

[fiel resignFirstResponder];

}
