带有文本框的故事板滚动视图 [英] Storyboard scroll view with text boxes

问题描述

我正在故事板中创建一个视图，该视图有一堆底部带有按钮的文本框.当我单击文本框时，键盘出现.这隐藏了我的一些文本框.所有文本框都位于滚动视图中.有没有办法在故事板中(如果没有，则在代码中)使滚动视图在键盘出现时在所有内容中正确滚动?

I am creating a view in a storyboard that has a bunch of text boxes with a button at the bottom. When I click in the text box the keyboard appears. This hides some of my text boxes. All text boxes live within the scrollview. Is there a way in storyboarding (if not then in code) to make the scrollview scroll properly amongst all the content when the keyboard appears?

我是否必须在键盘出现时动态更改内容大小，或者有没有办法设置滚动视图，以便在键盘出现时自动调整其大小.

Do I have to dynamically change the content size when the keyboard appears, or is there a way that I can set up the scroll view such that it automagically gets resized when the keyboard appears.

推荐答案

我想我和你有同样的问题，我所做的是在键盘出现或隐藏时动态更改滚动视图的 contenSize 属性.

I think I had the same problem as you, and what I did was to dynamically change the contenSize property of my scroll view when the keyboard appears or hides.

我在管理我的滚动视图的 ViewController 类中订阅了键盘通知:

I subscribed for keyboard notifications in the ViewController class that manages my scrollview:

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

然后在目标方法中调整大小:

And then do the resizing in the target method:

- (void)keyboardWillShow:(NSNotification *)note{
    NSDictionary *userInfo = note.userInfo;
    NSTimeInterval duration = [userInfo[UIKeyboardAnimationDurationUserInfoKey]      doubleValue];
    UIViewAnimationCurve curve = [userInfo[UIKeyboardAnimationCurveUserInfoKey] integerValue];
    //This is the value of the rect where the keyboard is drawn, and may come with height and width swapped
    CGRect keyboardFrame = [userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
    [UIView animateWithDuration:duration 
                          delay:0 
                        options:UIViewAnimationOptionBeginFromCurrentState | curve             
                     animations:^{
                          yourScrollableView.frame = ......
                     } 
                     completion:nil];

}

当然这同样适用于键盘隐藏.

Of course the same applies to keyboard hiding.
