Two UIScrollView only one appearing - iphone

Question

So Im making a two UIscrollview in my view. I'm using Ray Wenderlich's Custom Image Picker. But when I load it, only shows 1 imagepicker. I want to be able to load two image picker. I think Im doing something wrong with initWithCoder part. Cant seem to initialize it properly. Is it possible to have two ivars self. Sorry kinda new to iphoneDev. Thanks for your help.
Here's my whole implementation:
- (id) initWithCoder:(NSCoder *)aDecoder {
if ((self = [super initWithCoder:aDecoder])) {
_images = [[NSMutableArray alloc] init];
_thumbs = [[NSMutableArray alloc] init];
//THIS IS WHERE I THINK ITS WRONG but the upper part seems to be okay.
_images2 = [[NSMutableArray alloc] init];
_thumbs2 = [[NSMutableArray alloc] init];
}
return self;
}
- (void)addImage:(UIImage *)image {
[_images addObject:image];
[_thumbs addObject:[image imageByScalingAndCroppingForSize:CGSizeMake(60, 60)]];
}
- (void)addImage2:(UIImage *)image {
[_images2 addObject:image];
[_thumbs2 addObject:[image imageByScalingAndCroppingForSize:CGSizeMake(60, 60)]];
}
- (void) createScrollView {
self.slotBg = [[UIView alloc] initWithFrame:CGRectMake(43, 370, 300, 143)];
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = self.slotBg.bounds;
gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor grayColor] CGColor], (id)[[UIColor whiteColor] CGColor], nil];
[self.slotBg.layer insertSublayer:gradient atIndex:0];
[self.view addSubview:self.slotBg];
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0.0f,0.0f,300.0f,134.0f)];
[slotBg addSubview:scrollView];
int row = 0;
int column = 0;
for(int i = 0; i < _thumbs.count; ++i) {
UIImage *thumb = [_thumbs objectAtIndex:i];
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(column*60+10, row*60+10, 60, 60);
[button setImage:thumb forState:UIControlStateNormal];
[button addTarget:self
action:#selector(buttonClicked:)
forControlEvents:UIControlEventTouchUpInside];
button.tag = i;
[scrollView addSubview:button];
if (column == 4) {
column = 0;
row++;
} else {
column++;
}
}
[scrollView setContentSize:CGSizeMake(330, (row+1) * 60 + 10)];

Answer 1

In your createScrollView2 method, you alloc self.slotBg2, but then only reference self.slotBg when adding to your view. Then you add your scrollview2 to the original slotBg.
