获取资源文件夹中子目录的路径 [英] Get Path to Subdirectory in Resources Folder

问题描述

我试图在资源文件夹的子目录中获取所有 png 文件的数组.在我的应用程序资源文件夹中，我创建了一个名为图像"的文件夹.该文件夹包含我需要显示的所有 png 文件.

i'm trying to get an array of all png files in a subdirectory of the Resources Folder. In my apps Resources Folder I have created a Folder named "images". This folder holds all the png-files I need to display.

这是我尝试获取路径的方式:

This is the way I tried to get the Path:

    NSString *imagepath = [NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] bundlePath],@"images/"];

NSLog(@"Path to Images: %@", imagepath);

NSArray * paths = [NSBundle pathsForResourcesOfType: @"png" inDirectory:imagepath];
NSMutableArray * allImageNames = [[NSMutableArray alloc] init];

for ( NSString * path in paths )
{
    if ( [[path lastPathComponent] hasPrefix: @"AQ"] )
        continue;

    [allImageNames addObject: [path lastPathComponent]];
}

这样我就得到了一个像.../appname.app/images这样的路径

This way I get a Path like …/appname.app/images

但是如果我尝试这样做，数组总是空的.我做错了什么?

But if i try to do it that way, the array is always empty. What am I doing wrong?

问候，查拉克

推荐答案

刚刚解决了.

NSBundle *mainBundle = [NSBundle mainBundle];
NSArray *pngs = [mainBundle pathsForResourcesOfType:@".png"
 inDirectory:@"random pictures"];

 NSLog(@"pngs in my dir:%@", pngs);

目录结构:资源/随机图片".

dir structure: "Resources/random pictures".

这可行，但是，当您将文件添加到资源"时，您需要选中为任何添加的文件夹创建文件夹引用"，而不是为任何添加的文件夹创建组".

This works, BUT, when you add the files to 'Resources', you need to check "Create folder references for any aded folders", and NOT "Create groups for any added folders".

干杯！
