Question

我已经为侧边菜单实施了SASlideMenu，除了一件事以外，它都很棒。我不知道如何发送对象。

以下是切换视图：

-(void) switchToContentViewController:(UIViewController*) content{

    CGRect bounds = self.view.bounds;
    if (selectedContent) {


        //Animate out the currently selected UIViewController
        [UIView animateWithDuration:kSlideOutInterval delay:0.0 options:UIViewAnimationCurveEaseInOut animations:^{
            selectedContent.view.frame = CGRectMake(bounds.size.width,0,bounds.size.width,bounds.size.height);
        } completion:
         ^(BOOL completed) {

             [selectedContent willMoveToParentViewController:nil];
             [selectedContent.view removeFromSuperview];
             [selectedContent removeFromParentViewController];

             content.view.frame = CGRectMake(bounds.size.width,0,0,bounds.size.height);
             [self addChildViewController:content];
             [self.view addSubview:content.view];
             [UIView animateWithDuration:kSlideInInterval delay:0.0 options:UIViewAnimationCurveEaseInOut animations:^{
                 content.view.frame = CGRectMake(0,0,bounds.size.width,bounds.size.height);

             } completion:^(BOOL completed){
                 selectedContent = content;
                 [content didMoveToParentViewController:self];
                 [self.shield removeFromSuperview];
             }];
         }];
    }else{
        [self addChildViewController:content];
        [self.view addSubview:content.view];
        content.view.frame = CGRectMake(0,0,bounds.size.width,bounds.size.height);
        selectedContent = content;
        [self.shield removeFromSuperview];
        [content didMoveToParentViewController:self];
    }
}

我想要的是获取标识符（NSString）（我将知道如何解决），然后发送到这个将打开的新视图控制器。

我该怎么做？

您可以使用UIViewController的子类代替“内容”视图控制器的库存UIViewController类。在此子类上，您可以添加

@property (strong, nonatomic) NSString *stringForContentView;

然后，就在您将“内容”视图控制器添加为当前视图控制器的子项的行上方，

content.stringForContentView = @"A string that you already have";

如何将对象从一个视图发送到另一个视图？
