<>强实现代码:
- (void) addDoneButtonToNumPadKeyboard
｛
UIButton * doneButton=[UIButton buttonWithType UIButtonTypeCustom):;
如果(systemVersion & lt;8.0){
doneButton.frame=CGRectMake (0, 163, 106, 53);
其他}{
doneButton.frame=CGRectMake (0, SCREEN_SIZE。106年height-53, 53);
}
doneButton。标签=NUM_PAD_DONE_BUTTON_TAG;
doneButton。adjustsImageWhenHighlighted=没有;
[doneButton setTitle: @”完成“forState: UIControlStateNormal);
[doneButton setTitleColor:(用户界面颜色blackColor] forState: UIControlStateNormal);
[doneButton addTarget:自我行动:@ selector (doneButton:) forControlEvents: UIControlEventTouchUpInside);
NSArray * windowArr=[[UIApplication sharedApplication]视窗];
如果(windowArr !=nil,,windowArr。数比;1){
ui窗口* needWindow=(windowArr, objectAtIndex: 1);
UIView *键盘;
for (int i=0;我& lt;[needWindow。子视图数);我+ +){
键盘=[needWindow。子视图,objectAtIndex:我);
NSLog(@ % @”,[键盘描述]);
如果(([[键盘描述]hasPrefix: @ " & lt; UIPeripheralHostView "]==YES) | |([[键盘描述]hasPrefix: @ " & lt; UIKeyboard "]==YES) | |([[键盘描述]hasPrefix: @ " & lt; UIInputSetContainerView "]==YES)) {
UIView * doneButtonView=[键盘viewWithTag NUM_PAD_DONE_BUTTON_TAG):;
如果(doneButtonView==nil) {
[键盘addSubview: doneButton];
}
}
}
}
}
- (void) removeDoneButtonFromNumPadKeyboard
｛
UIView * doneButton=零;
NSArray * windowArr=[[UIApplication sharedApplication]视窗];
如果(windowArr !=nil,,windowArr。数比;1){
ui窗口* needWindow=(windowArr, objectAtIndex: 1);
UIView *键盘;
for (int i=0;我& lt;[needWindow。子视图数);我+ +){
键盘=[needWindow。子视图,objectAtIndex:我);
如果(([[键盘描述]hasPrefix: @ " & lt; UIPeripheralHostView "]==YES) | |([[键盘描述]hasPrefix: @ " & lt; UIKeyboard "]==YES) | |([[键盘描述]hasPrefix: @ " & lt; UIInputSetContainerView "]==YES)) {
doneButton=[键盘viewWithTag NUM_PAD_DONE_BUTTON_TAG):;
如果(doneButton !=nil) {
