iphone - UIWebView 键盘 - 摆脱 "Previous/Next/Done"栏

Question

我想去掉当您在 web View 中聚焦文本字段时出现的键盘顶部的栏。我们有一些其他的方法来处理这个，这是多余的和不必要的。

- (void)viewDidLoad {
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];

}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
}

- (void)keyboardWillShow:(NSNotification *)notification {
    [self performSelector:@selector(removeBar) withObject:nil afterDelay:0];
}

- (void)removeBar {
    UIWindow *keyboardWindow = nil;
    for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
        if (![[testWindow class] isEqual:[UIWindow class]]) {
            keyboardWindow = testWindow;
            break;
        }
    }

    for (UIView *possibleFormView in [keyboardWindow subviews]) {
        // iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
        if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
            for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {
                if ([[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
                    [subviewWhichIsPossibleFormView removeFromSuperview];
                }
            }
        }
    }
}

这很有效。
