iPad键盘不会被从视图控制器调用的Facebook对话框中关闭，该视图控制器具有模型视图控制器样式UIModalPresentationFormSheet [英] iPad keyboard will not dismiss from a Facebook dialog called from a view controller with a model view controller style UIModalPresentationFormSheet

问题描述

我已经从模式视图控制器研究并实施了关于键盘解除问题的建议，并在我的UINavigationController中有以下代码：

I have researched and implemented the advice regarding the keyboard dismissing issue from modal view controllers and have the following code in my UINavigationController

- (BOOL)disablesAutomaticKeyboardDismissal
{
    return NO;
}

这个工作正常，除非当用户执行下面的Facebook对话不解除键盘

This works fine except for when I call the following Facebook dialog when the user does not dismiss the keyboard

    [FBWebDialogs presentRequestsDialogModallyWithSession:...]

我尝试过在SO上找到的所有东西来杀死键盘;我已经走过了每一个视野;我已经尝试了模型转换到一个新的视图控制器，然后调用它;但没有接缝工作。它接缝好像键盘不再附加到视图，所以没有什么可以关闭它了。

I have tried everything I can find on SO to kill the keyboard; I have walked through each view; I have tried model transition to a new view controller and then calling it; but nothing seams to work. It seams as if the Keyboard is no longer attached to a view so there is nothing to dismiss it any more.

当我打电话给对话框时，我没有这个问题其他代码。

I do not have this issue when I call that dialog from other code.

感谢您的帮助。

推荐答案

如果视图控制器显示在导航控制器中，则修复不起作用;

The above "fix" does not work if the view controller is presented inside a navigation controller;

您必须使用此修复创建一个类别：

You have to create a category with this "fix":

头文件 - UINavigationControllerResponderFix.h：

header file - UINavigationControllerResponderFix.h:

#import <Foundation/Foundation.h> 
@interface UINavigationController (ResponderFix)

-(BOOL)disablesAutomaticKeyboardDismissal;

@end

实现文件：

#import "UINavigationControllerResponderFix.h"

@implementation UINavigationController (ResponderFix)

-(BOOL)disablesAutomaticKeyboardDismissal{
    return NO;
}

@end

现在，修改你的[applicationname ] -Prefix.pch

Now, modify your [applicationname]-Prefix.pch

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>

    #import "UINavigationControllerResponderFix.h"
#endif

这就是！

这是对UINavigationController的每个实例进行调整

This does is make an adjustment for every instance of UINavigationController
