-(void)keyboardWillShow : (NSNotification *)sender {
    @try  {
//      NSLog(@"notification in first view");
        for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows]) { 
            for (UIView *keyboard in [keyboardWindow subviews]) {
                if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES) {
                    NSValue *v = [[sender userInfo] valueForKey:UIKeyboardBoundsUserInfoKey];
                    CGRect kbBounds = [v CGRectValue];
                    if(keyboardToolbar == nil) {
                        keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectZero];
                        keyboardToolbar.barStyle=UIBarStyleBlackOpaque;
                        keyboardToolbar.tintColor = [UIColor colorWithRed:0.6 green:0.2 blue:0.6039 alpha:1];
                        UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(dismissKeyboard)];
                        UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
                        NSArray *items = [[NSArray alloc] initWithObjects:flex, barButtonItem, nil];
                        [keyboardToolbar setItems:items];
                        [items release];
                    }               
                    [keyboardToolbar removeFromSuperview];
                    keyboardToolbar.frame = CGRectMake(0, 0, kbBounds.size.width, 45);
                    [keyboard addSubview:keyboardToolbar];
                    keyboard.bounds = CGRectMake(kbBounds.origin.x, kbBounds.origin.y, kbBounds.size.width, kbBounds.size.height + 87);

                    for(UIView* subKeyboard in [keyboard subviews]) {
                        if([[subKeyboard description] hasPrefix:@"<UIKeyboardImpl"] == YES) {
                            subKeyboard.bounds = CGRectMake(kbBounds.origin.x, kbBounds.origin.y - 45, kbBounds.size.width, kbBounds.size.height);  
                        }                       
                    }
                }
            }
        }
    } @catch (NSException * e) {
//      NSLog(@"Problem in keyboardWillShow:%@",e);
    }

}

但此代码适用于iphone sdk 3.0，但此代码在iphone SDK 4.0中不起作用它表示uikeyboard反弹用户信息键在iphone 4.0操作系统中不推荐使用它不会创建带有完成按钮的工具栏请指导我怎么能这样做

Answer 1

您可以尝试使用

if ([[currentWindow description] hasPrefix:@"<UITextEffectsWindow"])
        {
            NSLog(@"Key board found");
}

但我认为你无法掩饰。您可以在其上添加自定义视图，但隐藏UIKeyboard我认为它不适用于iOS 4。

在iphone 4.0操作系统中不推荐使用UIKeyboardBoundsUserInfoKey
