How to make a horizontall scroll with images. Slideshow, coverflow,...etc

[Kaisser74]

Hello everyone.

I would like to make a slideshow of images.

A very simple app that shows a collection of images.

I ask Google, but I only found a complex/difficult examples.

I only want to move images from left to right and from right to left.

Someone can help me?

Thanks.

I am trying to change the size of images in this example:

ScrollViewSuite…

In the third project, "Tiling", in the method:

- (void)createThumbScrollViewIfNecessary {

if (!thumbScrollView) {

float scrollViewHeight = THUMB_HEIGHT + THUMB_V_PADDING;
float scrollViewWidth = [[self view] bounds].size.width;
thumbScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, scrollViewWidth, scrollViewHeight)];
[thumbScrollView setBackgroundColor:nil];
[thumbScrollView setCanCancelContentTouches:NO];
[thumbScrollView setClipsToBounds:NO];

// now place all the thumb views as subviews of the scroll view
// and in the course of doing so calculate the content width
float xPosition = THUMB_H_PADDING;
for (NSDictionary *imageDict in [self imageData]) {
NSString *name = [imageDict valueForKey:@"name"];
UIImage *thumbImage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_thumb.png", name]];
if (thumbImage) {
ThumbImageView *thumbView = [[ThumbImageView alloc] initWithImage:thumbImage];
[thumbView setDelegate:self];
[thumbView setImageName:name];
[thumbView setImageSize:CGSizeMake([[imageDict valueForKey:@"width"] floatValue], [[imageDict valueForKey:@"height"] floatValue])];
CGRect frame = [thumbView frame];
frame.origin.y = THUMB_V_PADDING;
frame.origin.x = xPosition;
[thumbView setFrame:frame];
[thumbView setHome:frame];
[thumbScrollView addSubview:thumbView];
[thumbView release];
xPosition += (frame.size.width + THUMB_H_PADDING);
}
}
[thumbScrollView setContentSize:CGSizeMake(xPosition, scrollViewHeight)];
}
}

I want to change the size of the thumbnails.
I can change the size of the "thumbScrollView" "control", but the images are bigger than the control.


Can anyone try to do it??

It´s very important.

Thanks, kind regards.

from the code posted, seem that you need to change the values of
THUMB_HEIGHT
[imageDict valueForKey:@"width"]
[imageDict valueForKey:@"height"]

Hi again.

THUMB_HEIGHT is for the UIScrollView and if the images are bigger than the UIscrollView, the images will not resized

I don´t know the size of the images that I will show, I must resize the images.

Thanks.
