How to Get file From one Document Folder to Another Document Folder? - iphone

Question

In my Application i save Recording file in Document Directory.then later gets all these file from document directory and showing all these files in My mainClass where i have UITableview for it.
When i Click on any row of this mainClass Tableview it goes to next Class where i play this file,delete this file and Send this file to my Favourite Recording Class where i have Tableview for it.Now my play button action method and delete Button action method works fine but i Don't know how to send this file to my Favurite Class Tableview.now i show here my delete button Code through which we can get the basic idea.
-(IBAction)deleteFile
{
NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir = [dirPaths objectAtIndex:0];
NSString *documentPath = [docsDir stringByAppendingPathComponent:#"MyRecordings"];
NSString *soundFilePath = [documentPath stringByAppendingPathComponent:fileToPlay];
recordedTmpFile = [NSURL fileURLWithPath:soundFilePath];
[[NSFileManager defaultManager] removeItemAtURL:recordedTmpFile error:nil];
}
As my Delete button Code show how we delete the Current Recording file which i selected from MainTableview .Now if the user Want to send the current Recording file to my Favourite Class Tableview instead of Deleting it then Whether i use the another Document folder here if answer is yes? then how we can save the Current file(recordedTmpFile) in this new Document folder.
-(IBAction)AddToFavourite
{
NSArray *dirPaths1 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir1 = [dirPaths1 objectAtIndex:0];
NSString *documentPath1 = [docsDir1 stringByAppendingPathComponent:#"MyFovouriteRecordings"];
// How to pass here the Current Recording File (recordedTmpFile) to this new document Folder.
}
When i NSlog recordedTmpFile it show result :file://localhost/Users/Umar/Library/Application%20Support/iPhone%20Simulator/4.2/Applications/9219677A-B0E3-4B78-B2E5-FEA49D689618/Documents/MyRecordings/06:Dec:12_05:54:07%20PM+Active%20song

-(IBAction)AddToFavourite {
NSArray *dirPaths1 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir1 = [dirPaths1 objectAtIndex:0];
NSString *documentPath1 = [docsDir1 stringByAppendingPathComponent:#"MyFovouriteRecordings"];
NSString *soundFilePath1 = [documentPath1 stringByAppendingPathComponent:fileToPlay];
// How to pass here the Current Recording File (recordedTmpFile) to this new document Folder.
// First check if the directory existst
if([[NSFileManager defaultManager] fileExistsAtPath:documentPath1]==NO) {
NSLog(#"Creating content directory: %#",documentPath1);
NSError *error=nil;
if([[NSFileManager defaultManager] createDirectoryAtPath:documentPath1 withIntermediateDirectories:NO attributes:nil error:&error]==NO) {
NSLog(#"There was an error in creating the directory: %#",error);
}
}
//then get the origin file path
NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir = [dirPaths objectAtIndex:0];
NSString *documentPath = [docsDir stringByAppendingPathComponent:#"MyRecordings"];
NSString *soundFilePath = [documentPath stringByAppendingPathComponent:fileToPlay];
//Then convert paths to URL
NSURL* originURL = [NSURL fileURLWithPath:soundFilePath];
NSURL* destinationURL = [NSURL fileURLWithPath:soundFilePath1];
//Then, you have to copy the file
[[NSFileManager defaultManager] copyItemAtURL:destinationURL toURL:originURL error:NULL];
}
That should do it, tell me if there is any error.

Just create an instance of NSData with your original file. Than write it to the other location.
//write file to the other location
NSData *myData = [[NSData alloc] initWithContentsOfFile:originalPath];
[myData writeToFile:newDataPath options:NSDataWritingAtomic error:&error];
//delete file from original location
NSFileManager *fileManager = [[NSFileManager alloc] init];
[fileManager removeItemAtPath:originalPath error:&removeError];
