数字键盘添加自定义按钮

项目需要对数字键盘做个性化设置，网上找了几个例子，学习了下，然后总结了一下：

 

数字键盘



 
身份证键盘

 



主要的代码如下

1.- (void)addButtonToKeyboardWithSelector:(SEL)sel normal:(UIImage*)nimg highlight:(UIImage*)himg{

2.     // create custom button

3.     UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];

4.     doneButton.tag=8;

5.     doneButton.frame = CGRectMake(0, 0, 106, 53);

6.     doneButton.adjustsImageWhenHighlighted = NO;

7.

8.     [doneButton setImage:nimg forState:UIControlStateNormal];

9.     [doneButton setImage:himg forState:UIControlStateHighlighted];

10.     [doneButton addTarget:self action:sel forControlEvents:UIControlEventTouchUpInside];

11.     // locate keyboard view

12.     int cnt=[[UIApplication sharedApplication] windows].count;

13.     UIWindow* keyboardWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:cnt-1];          

14.     doneButton.frame = CGRectMake(0, keyboardWindow.frame.size.height-53, 106, 53);

15.     [keyboardWindow addSubview:doneButton];

16.

17.      NSLog(@"keyboard:%@ %@ %@",NSStringFromCGRect(keyboardWindow.frame),NSStringFromCGRect(doneButton.frame),keyboardWindow.subviews);

18.}

19. 

20.- (void)removeButtonFromKeyboard {

21.    // locate keyboard view    

22.    int cnt=[[UIApplication sharedApplication] windows].count;

23.    UIWindow* keyboardWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:cnt-1];         23.24.[[keyboardWindow viewWithTag:8] removeFromSuperview];

25.}
