ios - 获取文件夹名称和图像名称

Question

代码:

NSString *path = [[NSBundle mainBundle] pathForResource:[objDynaMoThumbnailImages objectAtIndex:eg] ofType:@"jpg" inDirectory:[objDynaMoProductImagePath objectAtIndex:eg]];

它会像这样检索路径

/Users/software/Library/Application Support/iPhone Simulator/6.0/Applications/61AE2605-CE8E-404D-9914-CDA9EBA8027C/DynaMO.app/original/1-1.jpg

从上面的路径我只需要检索“original/1-1.jpg”。请帮助我......

如果资源位于应用程序包的任意子目录中，则可以使用以下代码。它不假设资源恰好是包路径下的一个子目录。

NSString *path = [[NSBundle mainBundle] pathForResource:...];
NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
NSString *relativePath;
if ([path hasPrefix:bundlePath]) {
    relativePath = [path substringFromIndex:([bundlePath length] + 1)];
} else {
    relativePath = path;
}

例如

path = /Users/software/Library/Application Support/.../DynaMO.app/sub/dir/image.jpg

会导致

relativePath = sub/dir/image.jpg
