View the contents of Custom Directory in iOS - ios

Question

I am creating a directory inside my application.Is there a code to view the contents of the directory in xcode. For example in android you can create a custom directory and view its contents using a file manager application. Can the similar procedure be done in apple?
Here is the code which i use to create a directory?
bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];
fileManager = [NSFileManager defaultManager];
myImageDirectory = [fileManager URLsForDirectory:NSApplicationSupportDirectory inDomains:NSUserDomainMask];
if ([myImageDirectory count] == 1){
NSLog(#"myImageDirectoryIs already present directory is already present");
}else{
directoryPath = [[myImageDirectory objectAtIndex:0] URLByAppendingPathComponent:bundleIdentifier];
NSLog(#"myImageDirectory directory name = %#",[directoryPath absoluteString]);
NSError *theError = nil;
if (![fileManager createDirectoryAtURL:directoryPath withIntermediateDirectories:NO attributes:nil error:&theError]){
NSLog(#"didnt write image data");
}else{
imagePath = [[directoryPath absoluteString] stringByAppendingPathComponent:[NSString stringWithFormat:#"/%#_%#_%#_image.jpg",dIdNo,iIdNo,[self currentDateandTime]]];
[imageData writeToFile:imagePath atomically:YES];
}
}

Answer 1

If your app is running in the simulator you'll need to use Finder. Go to the following directory:
/Users/<username>/Library/Application Support/iPhone Simulator/<iOS version>/Applications/<uuid>/Library/Application Support
If your app is running on the device you can use Xcode:
Connect the device
Choose menu option Window -> Organizer
Go to the Devices Tab
Click Applications under the device menu on the left
Pick your Application
The directory contents will be listed and you can optionally download everything.

try this...
to create a directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"/MyFolder"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
to retrieve contents from directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *customDirectory = [documentsDirectory stringByAppendingPathComponent:#"/MyFolder"];
NSError * error;
NSArray *directoryContents = [[NSFileManager defaultManager]
contentsOfDirectoryAtPath:customDirectory error:&error];
for(NSString *strFile in directoryContents)
{
NSString *strVideoPath = [NSString stringWithFormat:#"%#/%#",customDirectory,strFile];
if([[strVideoPath pathExtension] isEqualToString:#"mp4"] || [[strVideoPath pathExtension] isEqualToString:#"mov"])
{
[urlArray addObject:strVideoPath];
}
}

you can get the contents of the directory(MYNewFolder) from below code:
NSString *stringPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:#"MYNewFolder"];
NSArray *filePathsArray = [[NSFileManager defaultManager]
subpathsOfDirectoryAtPath:stringPath
error:nil];
for ( NSString *apath in filePathsArray )
{
NSLog(#"inside the file path array=%d",apath);
}

Method
-(NSArray *) getObjectsInDirectory:(NSString *)directory {
NSFileManager * fm = [NSFileManager defaultManager];
NSError * error = nil;
NSArray * result = [fm contentsOfDirectoryAtPath:directory error:&error];
return result;
}
How-To
NSString * documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSArray * files = [self getobjectsInDirectory:documentsPath];
This code is used to get an array of the files within the documents directory.
Viewing the Files
NSLog(#"%#", files);
