webView 下的UIKeyBoard的 inputAccessView处理
在输入的键盘上方加上一个view，作为一个toolBar,算是现在的基本需求，苹果自身有一个inputAccessoryView，是用来给这个view的，继承自NSObject (readonly),iputView与inputAccessoryView 在textView和textField都是read write属性。使用很简单
UIView*view1 = [[UIViewalloc]initWithFrame:CGRectMake(0, 0, 320, 20)];
view1.backgroundColor = [UIColorredColor];
self.viewText.inputAccessoryView= view1;
inputView就是显示键盘的view,如果重写这个view则，不再弹出键盘，而是弹出自己的view.
在 UIWebView 状态下，重写WebView的子类，赋予inputAccessView,重写getter setter方法，最终失败，没有起作用，网上搜索找到了一个隐藏inputAccessView的方法,先看看怎么隐藏的然后再考虑怎么写inputAccessView:
-(void)viewWillAppear:(BOOL)animated{
[[NSNotificationCenterdefaultCenter] addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
}
- (void)keyboardWillShow:(NSNotification *)note {
[selfperformSelector:@selector(removeBar) withObject:nilafterDelay:0];
}
- (void)removeBar {
// Locate non-UIWindow.
UIWindow *keyboardWindow = nil;
for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
if (![[testWindow class] isEqual:[UIWindow class]]) {
keyboardWindow = testWindow;
break;
}
}
// Locate UIWebFormView.
for (UIView *formView in [keyboardWindow subviews]) {
// iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
if ([[formView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
for (UIView *subView in [formView subviews]) {
if ([[subView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
[subView removeFromSuperview]; //这个view就是现在的inputAccessView,它的高度是44
}
elseif([[subView description] rangeOfString:@"UIImageView"].location != NSNotFound){
// remove the line above the input accessory view (changing the frame)
[subView setFrame:CGRectZero];
}
}
}
}
}
现在来看，咱们找到了怎么删除这个inputAccessView的方法 [subView removeFromSuperview]; 那么我直接改写这个subView呢？那样不就改了inputAccessView了么，事实上没有，这样没有效果，没有效果是吧，那就戴面具，直接写个view,然后 [subView addSubView:view]; OK这个方法可行。
