ScrollView가 제대로 스크롤되지 않습니다.

Question

내 스크롤보기가 튀어 나오지만 스크롤하지 않습니다.

- (void)populateStampList { 

    // create a mutable array to populate 

    imageNames = [[NSArray alloc] init]; 
    NSMutableArray *mImageNames = [[NSMutableArray alloc] init]; 


    // List of images 

    NSString *img1 = @"moustache";

    // set mutable array to array; 

    imageNames = mImageNames; 
    CGFloat contentSizeWidth = 0.0; 
    CGSize newSize = _scrollViewOutlet.frame.size; 


    for(int i = 0; i < [imageNames count]; i++){ 

     NSData *archivedData = [NSKeyedArchiver archivedDataWithRootObject:_firstImage];
