adding reflection to iCarousel - iphone

Question

I tried to add reflection to my icarousel. Firstly my code was like this and it was working wright.
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UIButton* button = (UIButton *)view;
if (button == nil)
{
//no button available to recycle, so create new one
UIImage *image = [arrKitapKapaklari objectAtIndex:index];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0.0f, 0.0f, image.size.width, image.size.height);
[button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
[button setBackgroundImage:image forState:UIControlStateNormal];
button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
}
//set button label
[button setTitle:[NSString stringWithFormat:#"%i", index] forState:UIControlStateNormal];
return button;
}
After changing, my code became like this:
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(ReflectionView *)view
{
UIButton* button = nil;
if (button == nil)
{
view = [[[ReflectionView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 200.0f)] autorelease];
//no button available to recycle, so create new one
UIImage *image = [arrKitapKapaklari objectAtIndex:index];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0.0f, 0.0f, image.size.width, image.size.height);
[button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
[button setBackgroundImage:image forState:UIControlStateNormal];
button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:button];
}
//set button label
[button setTitle:[NSString stringWithFormat:#"%i", index] forState:UIControlStateNormal];
[view update];
return view;
}
Reflection appears. But the problem is when i move the carousel view, images not flowing correctly. Sometimes another carousel view appears.
Do you have any idea what causes that?

Answer 1

Code should be:
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(ReflectionView *)view
{
UIButton* button = nil;
if (view == nil)
{
//no view available to recycle, so create new one
view = [[[ReflectionView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 200.0f)] autorelease];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = view.bounds;
[button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
button.tag = 99;
[view addSubview:button];
}
else
{
button = (UIButton *)[view viewWithTag:99];
}
//set button label
[button setTitle:[NSString stringWithFormat:#"%i", index] forState:UIControlStateNormal];
UIImage *image = [arrKitapKapaklari objectAtIndex:index];
[button setBackgroundImage:image forState:UIControlStateNormal];
[view update];
return view;
}

I use images with reflection built in them... don't need to do anything in code that way.. :p

Answer 3

I found my mistake. I am loading images here:
-(void) getImagesWithThread{
NSAutoreleasePool *pool;
pool = [[NSAutoreleasePool alloc] init];
//for(int i=0;i<bookCount;i++){
for(int i=0;i<bookCount;i++){
NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: [arrBookImages objectAtIndex:i]]];
UIImage *image = [[UIImage imageWithData: imageData] retain];
image = [self scaleToSize:CGSizeMake(140, 200) withImage:image];
if(image!=nil) [arrBookImages replaceObjectAtIndex:i withObject:image];
[image release]; }
[carousel reloadData];
[pool drain];
}
When i performed this in background it didn't reload correctly. İf i perform normally, it works. But i want to load them in a thread. I mean first i want to set images and replace them images from url. but i want them to appear one by one. Do you have any idea?
