UIResponder麻烦 [英] UIResponder Troubles

问题描述

今晚我一直在与UIResponder作战。这是我的困境。

Tonight I've been battling with UIResponder. Here's my predicament.

如果我输入

- (BOOL)canBecomeFirstResponder{
    return YES;
}

到我的mainViewController然后我可以获得震动事件..

to my mainViewController then I can get shake events..

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {

    if (event.type == UIEventSubtypeMotionShake) {
         //do something 
    }
}

但是，这意味着当我调用邮件表单和Web视图等内容时，键盘不会显示出来。

However, this means that when I call things like mail forms and webviews, the keyboard does not show up.

有什么方法可以让我的震动工作和键盘在模态视图中工作？

Is there any way I can get both shakes working and keyboard working in modal views?

我是尝试添加[self resignFirstResponder];
in -viewDidDissapear，当一个模态弹出时被调用，但没有运气。

I've tried adding [self resignFirstResponder]; in -viewDidDissapear, which gets called when a modal pops over, but no luck.

干杯

推荐答案

我遇到了与iOS相同的问题< 5.0，摇动事件并显示邮件表格。在呈现新的模态视图控制器之前，您必须重新签署第一个响应者。

I had the same problem with iOS < 5.0, shake event and showing a mail form. You have to resign the first responder before the new modal view controller is being presented.
