iOS的DropboxSDK,获取远程的子目录和内容 [英] iOS DropboxSDK, get remote subdirectories and contents
问题描述
我有几个子目录和文件在他们的Dropbox远程目录。
I have a remote directory with several subdirectories and files in them on Dropbox.
远程端:
-Mobile Profiles *(root)*
-- Custom Profiles
--- Profile1
--- Profile2
--- Profile3
上传的文件和目录/和子目录使用文件是没有问题的。我有一个大脑放屁的时候,它会得到从Dropbox的子目录及其内容到设备上。
Uploading the files and directories / and subdirectories with files is not a problem. I am having a brain fart when it comes to getting the subdirectories and their contents from dropbox to the device.
-(void)backupCustomProfiles {
for ( NSString *file in [[NSFileManager defaultManager] contentsOfDirectoryAtPath:MP_CUSTOM error:&error] ) {
[self.restClient uploadFile:file toPath:@"/Mobile Profiles/Custom Profiles/" fromPath:EasyStrings(MP_CUSTOM,file)];
}
}
获得
-(void)restoreCustomProfiles {
for ( ) {
/* ? */
}
}
我不知道如何通过遍历子目录在远程端。
I am not sure how to iterate through the subdirectories on the remote side.
推荐答案
首先加载目录元数据,然后加载它引用的文件。
First load the directory metadata, then load the files that it references.
要限制并行取数,使用NSOperationQueue所有loadMetadata和调用的loadFile限制并行取数。并避免多余的文件下载,记得在plist中下载的元数据。
To limit the number of parallel fetches, use a NSOperationQueue for all of the loadMetadata and loadFile calls to limit the number of parallel fetches. And to avoid redundant file downloads, remember the downloaded metadata in a plist.
- (void) restoreCustomProfiles
{
[self.client loadMetadata:@"/Mobile Profiles/Custom Profiles" withHash:hash];
}
- (void) restClient:(DBRestClient*)client loadedMetadata:(DBMetadata*)metadata
{
for (DBMetadata* child in metadata.contents) {
NSString *path = [child.path lowercaseString];
if (child.isDirectory) {
[client loadMetadata:child.path withHash:hash];
} else {
[client loadFile:pathToDownload intoPath:[
self.directory stringByAppendingString:path]];
}
}
}
- (void) restClient:(DBRestClient*)client loadedFile:(NSString*)destPath
{
// successfully downloaded a file to destPath
}
