如何从虚拟键盘IOS中删除prev next按钮 [英] how to remove prev next button from virtual keyboard IOS

问题描述

我在IOS 5中使用了UIWebview。我尝试设置 contenteditable =true以使uiwebview可编辑。

我的应用程序的屏幕截图类似于此链接中的图像。

这是一个灰色区域，但肯定是可能的。

见这里： http://ios-blog.co.uk/iphone-development-tutorials/rich-text-editing-a-simple-start-part-1/

注册键盘上的通知显示：

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

然后：

   - （void）keyboardWillShow：（NSNotification *）note {
 [self performSelector：@selector（removeBar）withObject：nil afterDelay：0]; 
} 
 
  - （void）removeBar {
 //找到非UIWindow。 
 UIWindow * keyboardWindow = nil; 
。对于（一个UIWindow *在[[UIApplication的sharedApplication]视窗] testWindow）{
如果（[[testWindow类] isEqual：方法[UIWindow类]]！）{
 keyboardWindow = testWindow; 
休息; 
} 
} 
 
 //找到UIWebFormView。 
 for（[keyboardWindow subviews]中的UIView * possibleFormView）{
 // iOS 5将UIWebFormView粘贴在UIPeripheralHostView中。 
如果（[[possibleFormView描述] rangeOfString：@ UIPeripheralHostView]！位置= NSNotFound）{
为（UIView的*在[possibleFormView子视图] subviewWhichIsPossibleFormView）{
如果（[[subviewWhichIsPossibleFormView descriptionOfString：@UIWebFormAccessory]。location！= NSNotFound）{
 [subviewWhichIsPossibleFormView removeFromSuperview]; 
} 
} 
} 
} 
}

It is a gray-area, but certainly possible.

See here: http://ios-blog.co.uk/iphone-development-tutorials/rich-text-editing-a-simple-start-part-1/

Register for notification on keyboard showing:

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

Then:

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