从 nsbundle 访问图像 [英] Accessing images from nsbundle

问题描述

我有一个框架，它试图从一个包中访问 xib 和图像.我能够很好地访问 xib，但无法在 UIImageView 中加载图像.我什至检查文件是否存在并且控制台输出是...

知道如何加载图像吗?

在框架视图控制器文件中加载xib的代码

self = [super initWithNibName:@"ViewController_iPad" bundle:[NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:@"MyBundle" ofType:@"bundle"]]];

加载图片的代码

- (void) loadImage{NSString *path = [[NSBundle mainBundle] pathForResource:@"MyBundle.bundle/test" ofType:@"png"];BOOL 存在 = 否；present = [[NSFileManager defaultManager] fileExistsAtPath:path];如果(存在){NSLog(@"MyBundle.bundle/test 存在");}别的{NSLog(@"MyBundle.bundle/test 不存在");}self.testImageView.image = [UIImage imageNamed:path];self.testImageView2.image = [UIImage imageWithContentsOfFile:path];}

MyTestHarnessApp[11671:c07] MyBundle.bundle/test 存在

解决方案

当您使用 imageNamed: 时，您必须只传递一个简单的文件名，并且该图像必须存在于应用程序资源包的根目录中.

您的图像不在资源包的根目录中，而是在子文件夹中.

既然你已经在path变量中获得了图片的完整路径，你必须使用UIImage imageWithContentsOfFile:方法:

self.testImageView.image = [UIImage imageWithContentsOfFile:path];

I have a framework which is trying to access xib's and images from a bundle. I am able to access the xib fine but unable to load the images in UIImageView. I even check if the file exists and the console output is yes...

Any idea how to load the image?

Code to load xib in the framework viewcontroller file

self = [super initWithNibName:@"ViewController_iPad" bundle:[NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:@"MyBundle" ofType:@"bundle"]]];

Code to load images

- (void) loadImage
{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"MyBundle.bundle/test" ofType:@"png"];
    BOOL present = NO;
    present = [[NSFileManager defaultManager] fileExistsAtPath:path];
    if (present)
    {
        NSLog(@"MyBundle.bundle/test exists");
    }
    else
    {
        NSLog(@"MyBundle.bundle/test does not exists");

    }

    self.testImageView.image = [UIImage imageNamed:path];

    self.testImageView2.image = [UIImage imageWithContentsOfFile:path];
}

MyTestHarnessApp[11671:c07] MyBundle.bundle/test exists

解决方案

When you use imageNamed: you must pass just a simple filename and the image must exist in the root of the app's resource bundle.

Your image is not in the root of the resource bundle, it is in a subfolder.

Since you have obtained the image's full path in the path variable, you must use the UIImage imageWithContentsOfFile: method:

self.testImageView.image = [UIImage imageWithContentsOfFile:path];
