ios - 如何将对象从一个 View 发送到另一个 View ？

Question

我已经实现了 SASlideMenu对于侧面菜单来说，除了一件事之外，一切都很棒。我不知道如何发送对象。

这是发生的 View 切换:

-(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];
    }
}

我想要的是在这里获取标识符(NSString)(我将知道如何解决)，然后发送到这个将打开的新 View Controller 。

我该怎么做？

Answer 1

您可以使用 UIViewController 的子类来代替“内容” View Controller 的常用 UIViewController 类。在此子类上，您可以添加

@property (strong, nonatomic) NSString *stringForContentView;

然后，在将“内容” View Controller 添加为当前 View Controller 的子级的行上方，

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