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 .

这是一个灰色地带，但肯定有可能.

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

注册键盘显示通知:

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

然后:

- (void)keyboardWillShow:(NSNotification *)note {[self performSelector:@selector(removeBar) withObject:nil afterDelay:0];}- (void)removeBar {//定位非 UIWindow.UIWindow *keyboardWindow = nil;for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {if (![[testWindow class] isEqual:[UIWindow class]]) {键盘窗口 = 测试窗口；休息;}}//定位 UIWebFormView.for (UIView *possibleFormView in [keyboardWindow subviews]) {//iOS 5 将 UIWebFormView 粘贴在 UIPeripheralHostView 中.if ([[possibleFormView 描述] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {if ([[subviewWhichIsPossibleFormView 描述] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {[subviewWhichIsPossibleFormView removeFromSuperview];}}}}}

i have use a UIWebview in IOS 5. I try to set contenteditable="true" to make uiwebview editable.

解决方案

This is an old answer and is no longer working on iOS 9. For an updated solution, see my answer here.

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/

[[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];
                }
            }
        }
    }
}
