有谁知道我如何在我的 iphone 应用程序中实现这个功能并使用目标 c?

解决方案

其实很简单.首先，您需要创建一个位于可见控制器下方的视图控制器.您可以像这样将该视图发送到后面:

[self.view sendSubviewToBack:menuViewController.view];

然后，您在导航栏的左侧放置一个菜单按钮，并编写类似如下的处理程序:

- (void)menuButtonPressed:(id)sender {CGRect 目的地 = self.navigationController.view.frame;如果 (destination.origin.x > 0) {目的地.origin.x = 0;} 别的 {目的地.origin.x += 254.5;}[UIView animateWithDuration:0.25 动画:^{self.navigationController.view.frame = 目的地；}完成:^(BOOL完成){self.view.userInteractionEnabled = !(destination.origin.x > 0);}];}

这是大体的想法.您可能需要更改代码以反映您的视图层次结构等.

Does anyone know how i can implement this feature in my iphone application and using objective c?

解决方案

It's pretty simple really. First, you need to make a view controller that sits under the one that's visible. You can send that view to the back like this:

[self.view sendSubviewToBack:menuViewController.view];

Then, you put a menu button on the left side of your navigation bar, and write a handler kind of like this:

- (void)menuButtonPressed:(id)sender {

    CGRect destination = self.navigationController.view.frame;

    if (destination.origin.x > 0) {
        destination.origin.x = 0;
    } else {
        destination.origin.x += 254.5;
    }

    [UIView animateWithDuration:0.25 animations:^{

        self.navigationController.view.frame = destination;        

    } completion:^(BOOL finished) {

        self.view.userInteractionEnabled = !(destination.origin.x > 0);

    }];
}

That's the general idea. You may have to change the code to reflect your view hierarchy, etc.
