Files are not being moved using NSFileManager - ios

Question

I am trying to use NSFileManager to move a file from the Documents/Inbox folder to the Documents folder. I used breakpoints to figure out where my code wasn't working, and everything seemed to be running fine until it hit the part where it actually moves the files. The directories are found and the files are noted in the debugger, but it just won't move. Here is my entire viewDidLoad method (there's nothing in [super viewDidLoad];):
//Turn every file inside the directory into an array
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *appFolderPath = [path objectAtIndex:0];
NSString *inboxAppFolderPath = [appFolderPath stringByAppendingString:#"/Inbox"]; //changes the directory address to make it for the inbox
//NSPredicates to filter out files I don't want in my NSArray
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"not SELF beginswith[c] '.DS_Store'"];
NSPredicate *inboxPredicate = [NSPredicate predicateWithFormat:#"not SELF beginswith[c] 'Inbox'"];
recipes = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:appFolderPath error:nil];
recipes = [recipes filteredArrayUsingPredicate:predicate];
recipes = [recipes filteredArrayUsingPredicate:inboxPredicate];
//get to inbox directory
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSArray *inboxContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[NSString stringWithFormat:inboxAppFolderPath,documentsDirectory] error:nil];
//move all the files over
for (int i = 0; i != [inboxContents count]; i++)
{
NSString *oldPath = [NSString stringWithFormat:inboxAppFolderPath, documentsDirectory, [inboxContents objectAtIndex:i]];
NSString *newPath = [NSString stringWithFormat:appFolderPath, documentsDirectory, [inboxContents objectAtIndex:i]];
[[NSFileManager defaultManager] moveItemAtPath:oldPath toPath:newPath error:nil];
}

There may be issue for creating sub folder inside Documents.
Try to create inboxAppFolder in this manner.
NSString *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
NSString *inboxAppFolderPath = [path stringByAppendingPathComponent:#"Inbox"]; // subDirectory
if (![[NSFileManager defaultManager] fileExistsAtPath: inboxAppFolderPath])
[[NSFileManager defaultManager] createDirectoryAtPath: inboxAppFolderPath withIntermediateDirectories:NO attributes:nil error:nil];
//Rest of your code
Hope, it'll help you.
Thanks.
