Answer 1

Creating A Folder
NSString *pngPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:[NSString stringWithFormat:#"/WB/%#",self.viewIndex]];
// Check if the directory already exists
BOOL isDir;
BOOL exists = [[NSFileManager defaultManager] fileExistsAtPath:pngPath isDirectory:&isDir];
if (exists)
{
if (!isDir)
{
NSError *error = nil;
[[NSFileManager defaultManager] removeItemAtPath:pngPath error:&error];
// Directory does not exist so create it
[[NSFileManager defaultManager] createDirectoryAtPath:pngPath withIntermediateDirectories:YES attributes:nil error:nil];
}
}
else
{
// Directory does not exist so create it
[[NSFileManager defaultManager] createDirectoryAtPath:pngPath withIntermediateDirectories:YES attributes:nil error:nil];
}
Adding Images to that Folder
NSString *pngImagePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:[NSString stringWithFormat:#"/WB/%#/%d.png",self.viewIndex,lineIndex]];
UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, 1.0);
[self.layer renderInContext:UIGraphicsGetCurrentContext()];
self.curImage = UIGraphicsGetImageFromCurrentImageContext();
[UIImagePNGRepresentation(self.curImage) writeToFile:pngImagePath atomically:YES];
UIGraphicsEndImageContext();

Try this :
//For save to Document Directory
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd"];
NSDateFormatter *timeFormat = [[NSDateFormatter alloc] init];
[timeFormat setDateFormat:#"HH:mm:ss"];
NSDate *now = [[NSDate alloc] init];
NSString *theDate = [dateFormat stringFromDate:now];
NSString *theTime = [timeFormat stringFromDate:now];
NSString *strImageName=[NSString stringWithFormat:#"Documents/MyPhotos/Dt%#%#.png",theDate,theTime];
strImageName=[strImageName stringByReplacingOccurrencesOfString:#"-" withString:#""];
strImageName=[strImageName stringByReplacingOccurrencesOfString:#":" withString:#""];
[self createDocumentDirectory:#"MyPhotos"];
NSString *pngPath = [NSHomeDirectory() stringByAppendingPathComponent:strImageName];
[UIImagePNGRepresentation(YourImageView.image) writeToFile:pngPath atomically:YES];
-(void)createDocumentDirectory:(NSString*)pStrDirectoryName
{
NSString *dataPath = [self getDocumentDirectoryPath:pStrDirectoryName];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:NULL];
}
-(NSString*)getDocumentDirectoryPath:(NSString*)pStrPathName
{
NSString *strPath = #"";
if(pStrPathName)
strPath = [[kAppDirectoryPath objectAtIndex:0] stringByAppendingPathComponent:pStrPathName];
return strPath;
}
//Get Photo Onebyone
NSError *error = nil;
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[self getDocumentDirectoryPath:#"MyPhotos"] error:&error];
if (!error) {
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"self ENDSWITH '.png'"];
NSArray *imagesOnly = [dirContents filteredArrayUsingPredicate:predicate];
for (int i=0;i<[imagesOnly count]; i++) {
[arrSaveImage addObject:[imagesOnly objectAtIndex:i]];//Save in your array.
}
}
