POHow to get a NSDictionary with NSArray with file paths?
text
Body
copied!<p>I have a NSArray which looks like this:</p> <pre><code>@[@"file1", @"directory/testfile", @"directory/otherdir/testfile", @"otherdir/", @"otherdir/otherfile"] </code></pre> <p>And I'm trying to convert it to a NSDictionary which looks like this:</p> <pre><code> @{ @"directory/":@{ @"otherdir/":@{ @"testfile":[..some array with data..]} }, @"testfile":[..some array with data..] }, @"otherdir/":@{ @"otherfile":[..some array with data..] }, @"file1":[..some array with data..] } </code></pre> <p>Basically, a NSDictionary which looks like a file tree. Thanks in advance!</p> <h3>EDIT: The actual array I have is this:</h3> <pre><code>( "blog/", "blog/code.css", "blog/style.css", "etc/", "etc/awsservices.png", "etc/speeds.png", "etc/test/", "etc/test/other/", "etc/test/other/speeds.png", "site/", "site/dino.png", "site/error.css", "site/main.css", "site/signet.min.js" ) </code></pre> <p>And the code I wrote for this:</p> <pre><code>-(NSDictionary*)buildDictionaryWithContentsOfPath:(NSMutableArray*)files { NSString *subDir; NSMutableDictionary *returnable = [[NSMutableDictionary alloc] initWithDictionary:@{}]; BOOL directory; NSLog(@"%@", files); for (S3ObjectSummary *objectSummary in files) { if ([[objectSummary key] hasSuffix:@"/"]) { if (subDir && [[objectSummary key] hasPrefix:subDir]) { NSLog(@"prefixed %@", [objectSummary key]); NSMutableDictionary *treeDict = [[NSMutableDictionary alloc] initWithDictionary:@{}]; [returnable[subDir] setObject:treeDict forKey:[objectSummary key]]; } else { subDir = [objectSummary key]; NSLog(@"dir %@", [objectSummary key]); NSMutableDictionary *treeDict = [[NSMutableDictionary alloc] initWithDictionary:@{}]; [returnable setObject:treeDict forKey:[objectSummary key]]; } directory = true; } else { S3GetObjectMetadataRequest *getMetadataRequest = [[S3GetObjectMetadataRequest alloc] initWithKey:[objectSummary key] withBucket:self.bucket.name]; S3GetObjectMetadataResponse *getMetadataResponse = [self.client getObjectMetadata:getMetadataRequest]; if (![[objectSummary key] hasPrefix:subDir]) { NSLog(@"file %@",[objectSummary key]); [returnable setObject:@{@"filename":[objectSummary key], @"directory":@(directory), @"created_at":getMetadataResponse.lastModified} forKey:[objectSummary key]]; } else { for (NSString __strong *pathComp in [[objectSummary key] pathComponents]) { pathComp = [NSString stringWithFormat:@"%@/", pathComp]; NSLog(@"path component %@", pathComp); if (![[objectSummary key] hasSuffix:@"/"]) { if (returnable[pathComp]) { NSLog(@"has comp %@", pathComp); [returnable[pathComp] setObject:@{@"filename":[objectSummary key], @"directory":@(directory), @"created_at":getMetadataResponse.lastModified} forKey:[objectSummary key]]; } } } } directory = false; } //[self.fileTree addObject:@{@"filename":[objectSummary key], @"directory":@(directory), @"created_at":getMetadataResponse.lastModified}]; } return returnable; } </code></pre> <p>And the dictionary it returns: </p> <pre><code>{ "blog/" = { "blog/code.css" = { "created_at" = "2013-12-07 12:13:37 +0000"; directory = 0; filename = "blog/code.css"; }; "blog/style.css" = { "created_at" = "2013-12-07 12:13:36 +0000"; directory = 0; filename = "blog/style.css"; }; }; "etc/" = { "etc/awsservices.png" = { "created_at" = "2013-12-07 12:26:37 +0000"; directory = 0; filename = "etc/awsservices.png"; }; "etc/speeds.png" = { "created_at" = "2013-12-07 13:29:27 +0000"; directory = 0; filename = "etc/speeds.png"; }; // PROBLEM HERE "etc/test/" = { }; "etc/test/other/" = { }; "etc/test/other/speeds.png" = { "created_at" = "2013-12-07 17:29:21 +0000"; directory = 0; filename = "etc/test/other/speeds.png"; }; // PROBLEM HERE }; "site/" = { "site/dino.png" = { "created_at" = "2013-12-07 12:13:59 +0000"; directory = 0; filename = "pmerino/dino.png"; }; "site/error.css" = { "created_at" = "2013-12-07 12:13:59 +0000"; directory = 0; filename = "pmerino/error.css"; }; "site/main.css" = { "created_at" = "2013-12-07 12:13:59 +0000"; directory = 0; filename = "pmerino/main.css"; }; "site/signet.min.js" = { "created_at" = "2013-12-07 12:13:59 +0000"; directory = 0; filename = "pmerino/signet.min.js"; }; }; } </code></pre> <p>As you can see, this part:</p> <pre><code>"etc/test/" = { }; "etc/test/other/" = { }; "etc/test/other/speeds.png" = { "created_at" = "2013-12-07 17:29:21 +0000"; directory = 0; filename = "etc/test/other/speeds.png"; }; </code></pre> <p>Should look like this:</p> <pre><code>"etc/" = { "test/" = { "other/" = { "speeds.png" = { "created_at" = "2013-12-07 17:29:21 +0000"; directory = 0; filename = "etc/test/other/speeds.png"; }; }; }; }; </code></pre>
