Display local image in UIImageView
提问by mirzahat
How do I display an image in the UIImageView component from the hard drive?
如何在 UIImageView 组件中显示来自硬盘的图像？
I have a local folder called "images" and would like to access it via a relative path, since I want to package the images with the app.
我有一个名为“images”的本地文件夹，我想通过相对路径访问它，因为我想用应用程序打包图像。

To load image from somewhere on your drive use:
要从驱动器上的某处加载图像，请使用：
UIImage * myImage = [UIImage imageWithContentsOfFile: @"../images/1.png"];
Or add image to the Xcode project and use:
或者将图像添加到 Xcode 项目并使用：
UIImage * myImage = [UIImage imageNamed: @"1.png"];
After that add image to imageview:
之后将图像添加到 imageview：
UIImageView * myImageView = [[UIImageView alloc] initWithImage: myImage];

You dont need to give any path as long as the image is in your resources folder.
只要图像在您的资源文件夹中，您就不需要提供任何路径。
You can display that image in the imageView using this.
您可以使用它在 imageView 中显示该图像。
yourImageView.image = [UIImage imageNamed:@"something.png"];

UIImage *img = [UIImage imageWithContentsOfFile:(the file path)];

What do you mean by images in hard drive.Are you saying that you have kept your images in your bundle in iphone app.If so then you can make array of those images like this....
硬盘驱动器中的图像是什么意思。你是说你已经把你的图像保存在你的 iphone 应用程序包中。如果是这样，那么你可以像这样制作这些图像的数组....
NSMutableArray *imageArray;
imageArray=[[NSMutableArray alloc]initWithObjects:@"001.jpg",@"002.jpg",@"003.jpg",@"004.jpg",nil];
And then can access your images by this array;
然后可以通过这个数组访问你的图像；
Or if you simply want to show a single image from the bundle you can do this way
或者，如果您只想显示捆绑包中的单个图像，您可以这样做
UIImageView *creditCardImageView=[[UIImageView alloc]initWithFrame:CGRectMake(10, 16, 302, 77)];
creditCardImageView.image=[UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"CreditCard_2RowTable" ofType:@"png"]];
[self.view addSubview:creditCardImageView];
This will help you.
这会帮助你。
