假设我的iPhone应用程序的“Resources”文件夹中有一个名为“Documents”的文件夹。
有没有办法在运行时获取该文件夹中包含的所有文件的数组或某种类型的列表?
因此,在代码中,它看起来像:
NSMutableArray *myFiles = [...get a list of files in Resources/Documents...];
这可能吗?
答案 0 :(得分:131)
您可以像这样获取Resources
目录的路径,
NSString * resourcePath = [[NSBundle mainBundle] resourcePath];
然后将Documents
附加到路径
NSString * documentsPath = [resourcePath stringByAppendingPathComponent:@"Documents"];
然后,您可以使用NSFileManager
。
NSError * error;
NSArray * directoryContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsPath error:&error];
注意:将源文件夹添加到捆绑包中时,请确保选择“复制时为任何添加的文件夹创建文件夹参考”

更新了Swift 3
let docsPath = Bundle.main.resourcePath! + "/Resources"
let fileManager = FileManager.default
do {
let docsArray = try fileManager.contentsOfDirectory(atPath: docsPath)
} catch {
print(error)
}

您也可以尝试以下代码:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSError * error;
NSArray * directoryContents = [[NSFileManager defaultManager]
contentsOfDirectoryAtPath:documentsDirectory error:&error];
NSLog(@"directoryContents ====== %@",directoryContents);

Swift版本:
if let files = try? FileManager.default.contentsOfDirectory(atPath: Bundle.main.bundlePath ){
for file in files {
print(file)
}
}

列出目录中的所有文件
NSFileManager *fileManager = [NSFileManager defaultManager];
NSURL *bundleURL = [[NSBundle mainBundle] bundleURL];
NSArray *contents = [fileManager contentsOfDirectoryAtURL:bundleURL
includingPropertiesForKeys:@[]
options:NSDirectoryEnumerationSkipsHiddenFiles
error:nil];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"pathExtension ENDSWITH '.png'"];
for (NSString *path in [contents filteredArrayUsingPredicate:predicate]) {
// Enumerate each .png file in directory
}
递归枚举目录中的文件
NSFileManager *fileManager = [NSFileManager defaultManager];
NSURL *bundleURL = [[NSBundle mainBundle] bundleURL];
NSDirectoryEnumerator *enumerator = [fileManager enumeratorAtURL:bundleURL
includingPropertiesForKeys:@[NSURLNameKey, NSURLIsDirectoryKey]
options:NSDirectoryEnumerationSkipsHiddenFiles
errorHandler:^BOOL(NSURL *url, NSError *error)
{
NSLog(@"[Error] %@ (%@)", error, url);
}];
NSMutableArray *mutableFileURLs = [NSMutableArray array];
for (NSURL *fileURL in enumerator) {
NSString *filename;
[fileURL getResourceValue:&filename forKey:NSURLNameKey error:nil];
NSNumber *isDirectory;
[fileURL getResourceValue:&isDirectory forKey:NSURLIsDirectoryKey error:nil];
// Skip directories with '_' prefix, for example
if ([filename hasPrefix:@"_"] && [isDirectory boolValue]) {
[enumerator skipDescendants];
continue;
}
if (![isDirectory boolValue]) {
[mutableFileURLs addObject:fileURL];
}
}

Swift 3 (并返回网址)
let url = Bundle.main.resourceURL!
do {
let urls = try FileManager.default.contentsOfDirectory(at: url, includingPropertiesForKeys:[], options: FileManager.DirectoryEnumerationOptions.skipsHiddenFiles)
} catch {
print(error)
}

如果您必须使用子目录"相对于项目" (蓝色文件夹),您可以写:
func getAllPListFrom(_ subdir:String)->[URL]? {
guard let fURL = Bundle.main.urls(forResourcesWithExtension: "plist", subdirectory: subdir) else { return nil }
return fURL
}
<强>用法强>:
if let myURLs = getAllPListFrom("myPrivateFolder/Lists") {
// your code..
}
