iphone – 如何在iOS中递归收集我的软件包中的所有资源路径？

NSArray *filePaths = [NSBundle pathsForresourcesOfType:@"txt" inDirectory:[[[NSBundle mainBundle] bundlePath] StringByAppendingString:@"/unzipped"]];

我使用@rekle发布的代码作为起点,得到了这个工作.诀窍就是使用NSDirectoryEnumerator,它会递归地执行.这是我写的功能,万一有人需要它.

- (NSArray *)recursivePathsForresourcesOfType:(NSString *)type inDirectory:(NSString *)directoryPath{

    NSMutableArray *filePaths = [[NSMutableArray alloc] init];

    // Enumerators are recursive
    NSDirectoryEnumerator *enumerator = [[[NSFileManager defaultManager] enumeratorAtPath:directoryPath] retain];

    NSString *filePath;

    while ((filePath = [enumerator nextObject]) != nil){

        // If we have the right type of file,add it to the list
        // Make sure to prepend the directory path
        if([[filePath pathExtension] isEqualToString:type]){
            [filePaths addObject:[directoryPath StringByAppendingPathComponent:filePath]];
        }
    }

    [enumerator release];

    return [filePaths autorelease];
}

Swift,使用NSURL

func recursivePathsForresources(type type: String) -> [NSURL] {

    // Enumerators are recursive
    let enumerator = NSFileManager.defaultManager().enumeratorAtPath(bundlePath)
    var filePaths = [NSURL]()

    while let filePath = enumerator?.nextObject() as? String {

        if NSURL(fileURLWithPath: filePath).pathExtension == type {
            filePaths.append(bundleURl.URLByAppendingPathComponent(filePath))
        }
    }

    return filePaths
}
