NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];

//TimeStamp getting random number
int randomNumber = [self getRandomNumber:9 to:9999999999];

//Creating Time stamp for specific name of save Image

NSString * timeStampValue = [NSString stringWithFormat:@”%ld”, (long)[[NSDate date] timeIntervalSince1970]];

[self setImagePath:[documentsDir stringByAppendingPathComponent:[NSString stringWithFormat:@”savePhoto%@%d.png”,timeStampValue,randomNumber]]];

BOOL isDone =[fileManager createFileAtPath:imagePath contents:imageData attributes:nil];

NSLog(@”Saved Image Document Directory”); }
else {
NSLog(@”Not Save”);

-(int)getRandomNumber:(int)from to:(int)to {

return (int)from + arc4random() % (to-from+1);

// getting the image

– (UIImage*)getImage_FromName :(NSString *)imageName {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:imageName];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
return img;
