PagerView changing frame size dynamically about fspagerview

[dkcas11]

Would it be possible to set the size, ie. change it, every time you create your cell?

@dkcas11 I recieve JSON, parse and have many items with photos, I want to show all of them in pageControl with animation (like a promo of goods). Photos have different sizes (also, landscape and portrait orientations). When I make collectionView, I put all photos in array with custom size (I calculated it from static height). Code is bellow. And make the cell of collectionView that size, that the photo has. I want to do the same with self.pageControl, is it really?

`- (UIImage*)resizingImage:(UIImage*)image {

CGFloat scaleFactor = targetHeight / image.size.height;
CGFloat targetWidth = image.size.width * scaleFactor;
CGSize targetSize = CGSizeMake(targetWidth, targetHeight);
UIImage* scaledImage = [SiSCollectionViewController imageWithImage:image scaledToSize:targetSize];

return scaledImage;

}

• (UIImage *)imageWithImage:(UIImage *)image scaledToSize:(CGSize)newSize {
  UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
  [image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
  UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();
  return newImage;
  }`

I want to have pagerView size only for image (without white color by sides)

Well one thing you could do, is scale all images to have the same width, but varying height. This way you ensure that the correct content is always displayed to the user.
I haven't tried it, but maybe you can use the itemSize in the cellForItemAt delegate function, before you return the cell, with its size applied to the pagerView.
Otherwise, you will have to subclass the FSPagerViewCell and make your own that supports this.

@dkcas11 Thank you very much for help but I can't understand what I should to do with itemSize. I set it property in cell making method and it show other photos incorrect. I add video to show how it works. May be I should to check if it current photo then change itemSize if no - reload itemSize (or use the default sizes)...

I see.. I think you will have to subclass FSPagerViewCell and create the cell yourself, in order to support this.

@dkcas11 This is so hard to me, because I make the project with Objective-C language but the framework is on Swift written. It is so difficult level for me to make Objective-C class by subclass of swift. So I'll use it with aspectFill images. Looks so nice.
