数据不在类之间发送

本文介绍了数据不在类之间发送-Objective-C的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试在两个班级之间发送数据。我已经使用properties方法完成了该操作，但是数据仍然在另一侧空着。

I'm trying to send data between two classes. I've done it using the properties method, but the data keeps coming back on the other side empty.

FrameGallery.h（正在发送数据的类）：

@interface FrameGallery{ NSMutableArray *filesArray; } @property (nonatomic, retain) NSMutableArray *filesArray; @end

FrameGallery.m

#import "FrameGallery.h" @implementation FrameGallery @synthesize filesArray;

LoadFilePopOverController.m（正在接收数据的类）

FrameGallery *frameGallery = [[FrameGallery alloc] init]; NSLog(@"%@", frameGallery.filesArray);

我在这里确实缺少某些东西吗？

Is there something that I'm missing here that's really obvious?

我过去已经成功完成了，但是找不到使用它的代码。任何帮助将不胜感激。

I've done it successfully in the past but I can't find the code where I used it. Any help would be appreciated.

推荐答案

在LoadFilePopOverController中创建一个数组并使其成为属性，然后对其进行合成。

Create an array in your LoadFilePopOverController and make it a property , synthesize it.

现在，当您从FrameGallery导航到LoadFilePopOverController时，将数组分配给在LoadFilePopOverController中创建的数组。

Now when you navigate to LoadFilePopOverController from FrameGallery , assign the array to the one that was created in LoadFilePopOverController.

例如，

在LoadFilePopOverController.h

in LoadFilePopOverController.h

NSMutableArray *getdata; @property (nonatomic, retain) NSMutableArray *getdata;

in .m

@synthesize getdata;

现在在FrameGallery.m中，转到执行导航的代码并将数组设置为：

Now in your FrameGallery.m , go to the code where you are performing your navigation, and set the array like:

Loadvc.getdata = filesArray;
