iPhone - My new view is blocking my toolbar - iphone

Question

I have a problem with my app. With help by a tutorial I've created a slideshow with pictures. I've added a toolbar so it's possible to go back. The problem is that when the pictures are showing, the toolbar disappear. I've been trying to google the problem and so on, but I can't solve it. In a "previous" class I create SlideShowViewController, and inside that class I have another one called SlideShowView. I hope this ain't to messy or stupid, cause I really need help.
Here is the code:
#import "SlideShowViewController.h"
#import "Pictures.h"
#interface SlideShowView : UIView
{
NSArray * mImages;
UIImageView * mLeftImageView;
UIImageView * mCurrentImageView;
UIImageView * mRightImageView;
NSUInteger mCurrentImage;
Pictures *picRef;
SlideShowViewController *slideRef;
BOOL mSwiping;
CGFloat mSwipeStart;
}
- (id)initWithImages:(NSArray *)inImages;
#end // SlideShowView
#pragma mark -
//#import "SlideShowViewController.h"
#implementation SlideShowView
- (UIImageView *)createImageView:(NSUInteger)inImageIndex
{
if (inImageIndex >= [mImages count])
{
return nil;
}
UIImageView * result = [[UIImageView alloc] initWithImage:[mImages objectAtIndex:inImageIndex]];
result.opaque = YES;
result.userInteractionEnabled = NO;
result.backgroundColor = [UIColor whiteColor];
result.contentMode = UIViewContentModeScaleAspectFit;
result.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
return result;
}
- (id)initWithImages:(NSArray *)inImages
{
if (self = [super initWithFrame:CGRectZero])
{
mImages = [inImages retain];
NSUInteger imageCount = [inImages count];
if (imageCount > 0)
{
mCurrentImageView = [self createImageView:0];
[self addSubview:mCurrentImageView];
if (imageCount > 1)
{
mRightImageView = [self createImageView:1];
[self addSubview:mRightImageView];
}
}
self.opaque = YES;
self.backgroundColor = [UIColor whiteColor];
self.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
}
return self;
}

Answer 1

Instead of this:
self.view = [[[SlideShowView alloc] initWithImages:images] autorelease];
do that:
UIView* slideShowView = [[[SlideShowView alloc] initWithImages:images] autorelease];
[self.view addSubview:slideShowView];
EDIT: Also don't forget to set the frame of slideShowView!
