 NSFileManager *fileManager = [NSFileManager defaultManager];  

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);    NSString *documentsDirectory = [paths objectAtIndex:0];NSLog(@"%d",[paths count]);NSError *error = nil;NSArray *fileList = [[NSArray alloc] init];NSMutableArray *filePath = [NSMutableArray arrayWithCapacity:100 ];NSMutableArray *imgArray = [NSMutableArray arrayWithCapacity:200];//NSArray *filePath = [[NSArray alloc] init];fileList = [fileManager contentsOfDirectoryAtPath:documentsDirectory error:&error];for (NSString *file in fileList) {NSLog(@"fileName is :%@",file);[filePath addObject:[documentsDirectory stringByAppendingPathComponent:file]];} for (int i = 0; i<[fileList count]; i++) { UIImage *temp = [UIImage imageWithContentsOfFile:[filePath objectAtIndex:i]]; [imgArray addObject:temp]; } [imgView1 setImage:[imgArray objectAtIndex:0]];[imgView2 setImage:[imgArray objectAtIndex:1]];[imgView3 setImage:[imgArray objectAtIndex:2]];[imgView4 setImage:[imgArray objectAtIndex:3]];[imgView5 setImage:[imgArray objectAtIndex:4]];[imgView6 setImage:[imgArray objectAtIndex:5]];[imgView7 setImage:[imgArray objectAtIndex:6]];[imgView8 setImage:[imgArray objectAtIndex:7]];[imgView9 setImage:[imgArray objectAtIndex:8]];
