Copy files from Directory to Directory in iOS Objective-C - ios

Question

In my app I want to copy files from one directory to another directory. In the source directory there are files and folders.
I do this in the code below:
- (BOOL)copyDirectory:(NSString*)Directory toDirectory:(NSString*)targetDirectory
{
NSLog(#"start copy");
#try
{
NSError *error = nil;
NSString *path = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory,NSUserDomainMask,YES) objectAtIndex:0];
NSString *folderPath = [path stringByAppendingPathComponent:targetDirectory];
BOOL succes = [[NSFileManager defaultManager] fileExistsAtPath:folderPath];
if(succes){
return NO;
}
else
{
NSString *wwwPath = [[NSBundle mainBundle] pathForResource:Directory ofType:nil];
NSArray *target= [[NSFileManager defaultManager] contentsOfDirectoryAtPath:wwwPath error:&error];
[[NSFileManager defaultManager] createDirectoryAtPath:folderPath withIntermediateDirectories:NO attributes:nil error:nil];
int a = 0 ;
for(a = 0 ; a < target.count;a++){
NSString *temp = [target objectAtIndex:a];
if([temp rangeOfString:#"."].location == NSNotFound)
{
NSString *sourceDirectory = [NSString stringWithFormat:#"%#/%#",Directory,temp ];
NSString *DestanistionDirectory = [NSString stringWithFormat:#"%#/%#",targetDirectory,temp];
if([self copyDirectory:sourceDirectory toDirectory:DestanistionDirectory] == NO){
return NO;
}
}
else
{
NSString *source = [NSString stringWithFormat:#"%#/%#",wwwPath,temp];
NSString *target = [NSString stringWithFormat:#"%#/%#",folderPath,temp];
BOOL result = [[NSFileManager defaultManager] copyItemAtPath:source toPath:target error:&error];
if(result)
currentFileCounter++;
[self performSelectorInBackground:#selector(updatePrograsBar) withObject:nil];
if(error != nil){
if(IsDEBUG) NSLog(#"error: %#",[error description]);
return NO;
}
}
}
}
}
#catch (NSException *exception)
{
if(IsDEBUG)NSLog(#"%#",exception.description);
return NO;
}
NSLog(#"end copy");
return YES;
}
To save time, when I call to
- (BOOL)copyDirectory:(NSString*)Directory to Directory:(NSString*)target Directory
in recursive I call in new thread.
- (BOOL)copyDirectory:(NSString*)Directory toDirectory:(NSString*)targetDirectory
{
NSLog(#"start copy");
#try
{
NSError *error = nil;
NSString *path = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory,NSUserDomainMask,YES) objectAtIndex:0];
NSString *folderPath = [path stringByAppendingPathComponent:targetDirectory];
BOOL succes = [[NSFileManager defaultManager] fileExistsAtPath:folderPath];
if(succes){
return NO;
}
else
{
NSString *wwwPath = [[NSBundle mainBundle] pathForResource:Directory ofType:nil];
NSArray *target= [[NSFileManager defaultManager] contentsOfDirectoryAtPath:wwwPath error:&error];
[[NSFileManager defaultManager] createDirectoryAtPath:folderPath withIntermediateDirectories:NO attributes:nil error:nil];
int a = 0 ;
for(a = 0 ; a < target.count;a++){
NSString *temp = [target objectAtIndex:a];
if([temp rangeOfString:#"."].location == NSNotFound)
{
NSString *sourceDirectory = [NSString stringWithFormat:#"%#/%#",Directory,temp ];
NSString *DestanistionDirectory = [NSString stringWithFormat:#"%#/%#",targetDirectory,temp];
dispatch_async(dispatch_get_global_queue(0, 0), ^{
[self copyDirectory:sourceDirectory toDirectory:DestanistionDirectory];
});
}
else
{
NSString *source = [NSString stringWithFormat:#"%#/%#",wwwPath,temp];
NSString *target = [NSString stringWithFormat:#"%#/%#",folderPath,temp];
BOOL result = [[NSFileManager defaultManager] copyItemAtPath:source toPath:target error:&error];
if(result)
currentFileCounter++;
[self performSelectorInBackground:#selector(updatePrograsBar) withObject:nil];
if(error != nil){
if(IsDEBUG) NSLog(#"error: %#",[error description]);
return NO;
}
}
}
}
}
#catch (NSException *exception)
{
if(IsDEBUG)NSLog(#"%#",exception.description);
return NO;
}
NSLog(#"end copy");
return YES;
}
but I need to know when is finish to copy all the files and folder and not return from the main call to
-(BOOL)copyDirectory:(NSString*)Directory to Directory:(NSString*)target Directory
until finish all.
