iOS：从plist文件加载图像 [英] iOS : Load image from plist file

问题描述

我试图将plist文件中的各种图像显示到UIImageView中，我编写了这样的代码：

I am trying to show various images from a plist file into UIImageView , I wrote my code like this :

NSDictionary *picturesDictionary = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Photos" ofType:@"plist"]];    
    imageArray = [picturesDictionary objectForKey:@"PhotosArray"];
    PhotosInAlbum.image = [UIImage imageWithContentsOfFile:[imageArray objectAtIndex:1]];

但实际上没有任何反应，我的ImageView是空的！我也有两个按钮来转发后向图像。

But actually nothing happens, and my ImageView is empty ! also I have two buttons to forward backward images .

Plist的内容：

Contents of Plist :

推荐答案

plist不正确，应该是

The plist is incorrect, it should be

Root ---- Dictionary
     PhotosArray ----- Array
         Item 0   ------ String -- Beach.jpg

然后将此代码添加到viewController中。确保接口imageView链接到IBOutlet。

Then add this code to your viewController.. Be sure that the Interface imageView is link to IBOutlet.

NSDictionary *picturesDictionary = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Photos" ofType:@"plist"]];     
NSArray *imageArray = [picturesDictionary objectForKey:@"PhotosArray"]; 
PhotosInAlbum.image = [UIImage imageNamed:[imageArray objectAtIndex:0]];
