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:
主要的代码如下
- (void)addButtonToKeyboardWithSelector:(SEL)sel normal:(UIImage*)nimg highlight:(UIImage*)himg{
// create custom button
UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
doneButton.tag=8;
doneButton.frame = CGRectMake(0, 0, 106, 53);
doneButton.adjustsImageWhenHighlighted = NO;
[doneButton setImage:nimg forState:UIControlStateNormal];
[doneButton setImage:himg forState:UIControlStateHighlighted];
[doneButton addTarget:self action:sel forControlEvents:UIControlEventTouchUpInside];
// locate keyboard view
//这样更合理一点
int cnt=[[UIApplication sharedApplication] windows].count;
UIWindow* keyboardWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:cnt-1];
doneButton.frame = CGRectMake(0, keyboardWindow.frame.size.height-53, 106, 53);
if([[keyboardWindow description] hasPrefix:@"
[keyboardWindow addSubview:doneButton];
NSLog(@"keyboard:%@ %@ %@",NSStringFromCGRect(keyboardWindow.frame),NSStringFromCGRect(doneButton.frame),keyboardWindow.subviews);
}
- (void)removeButtonFromKeyboard {
// locate keyboard view
for (NSUInteger i=0; i<[[UIApplication sharedApplication] windows].count; i++) {
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:i];
if([[tempWindow description] hasPrefix:@"
[[tempWindow viewWithTag:8] removeFromSuperview];
}
}
}
