我已经使用发布在其他线程中的解决方案向数字键盘添加了一个自定义的“完成”按钮,例如这个。随着 iOS 8.3 的更新,一些事情发生了变化,因为按钮仍然出现,但触摸通知永远不会触发。将按钮从键盘视图移动到超级视图会破坏按钮的位置,但可以证明控制工作的通知。
它的行为就像自定义按钮位于键盘上的透明层后面,并且无法进行任何触摸。
- (void)addButtonToKeyboard
{
// create custom button
self.doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.doneButton.frame = CGRectMake(0, 163+44, 106, 53);
self.doneButton.adjustsImageWhenHighlighted = NO;
[self.doneButton setTag:67123];
[self.doneButton setImage:[UIImage imageNamed:@"doneup1.png"] forState:UIControlStateNormal];
[self.doneButton setImage:[UIImage imageNamed:@"donedown1.png"] forState:UIControlStateHighlighted];
[self.doneButton addTarget:self action:@selector(doneButton:) forControlEvents:UIControlEventTouchUpInside];
// locate keyboard view
int windowCount = [[[UIApplication sharedApplication] windows] count];
if (windowCount < 2) {
return;
}
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for(int i = 0 ; i < [tempWindow.subviews count] ; i++)
{
keyboard = [tempWindow.subviews objectAtIndex:i];
// keyboard found, add the button
if([[keyboard description] hasPrefix:@"<UIPeripheralHost"] == YES){
UIButton* searchbtn = (UIButton*)[keyboard viewWithTag:67123];
if (searchbtn == nil)//to avoid adding again and again as per my requirement (previous and next button on keyboard)
[keyboard addSubview:self.doneButton];
}//This code will work on iOS 8.0
