Question

I have a UIViewController with a UIImageView in it and a array of UIImage. How Can I develop slide feature to right or left in order to change the image to the next array position?

Answer 1

The common approach is a UIScrollView the size of one of the images, with paging enabled.

Add the images as subviews and set the content size like this…

NSArray *images;
CGSize imageSize;

self.scrollView.frame = CGRectMake(10,10,imageSize.width,imageSize.height);
self.scrollView.contentSize = CGSizeMake(imageSize.width * images.count, imageSize.height);
self.scrollView.pagingEnabled = YES;

CGFloat xPos = 0.0;

for (UIImage *image in images) {
    UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
    imageView.frame = CGRectMake(xPos, 0.0, imageSize.width, imageSize.width);
    [self.scrollView addSubview:imageView];
    xPos += imageSize.width;
    // assuming ARC, otherwise release imageView
}

You might also turn off bounce, scrolling indicators, etc. depending on the details of the effect you want.
