I am currently making a simple scroll view with swift (sliding to the next picture).I was able to display the image, but the screen is full and I can't display it beautifully with the aspect ratio adjusted.
scrollView.contentMode=UIViewContentMode.ScaleAspectFit
I'm inserting , but what's wrong with it?
Professor, please.
import UIKit
classViewController:UIViewController {
varscrollView —UIScrollView!
varpageImagesArr=["1.jpg", "2.jpg", "3.jpg" ];
override func viewDidLoad(){
super.viewDidLoad()
let width=self.view.frame.maxX, height=self.view.frame.maxY
let pageSize=self.pageImagesArr.count;
// Create ScrollView
scrollView = UIScrollView (frame:self.view.frame)
scrollView.pagingEnabled=true
scrollView.frame = CGRectMake(0,0, width, height);
scrollView.contentSize=CGSizeMake (CGFloat(pageSize)*width, 0)
__scrollView.contentMode=UIViewContentMode.ScaleAspectFit__
// Create each page
for vari=0;i<pageSize;i++{
let img: UIImage=UIImage(named:self.pageImagesArr[i])!;
letiv: UIImageView= UIImageView (image:img);
iv.frame = CGRectMake (CGFloat(i)*width, 0, width, height);
scrollView.addSubview(iv)
}
self.view.addSubview(scrollView)
}
override funcdidReceiveMemoryWarning(){
super.didReceiveMemoryWarning()
}
}
I'm sorry that I couldn't check it on hand, but
Why don't you set up AspectFit in the UIImageView?
//Create each page
for vari=0;i<pageSize;i++{
let img: UIImage=UIImage(named:self.pageImagesArr[i])!;
letiv: UIImageView= UIImageView (image:img);
// hold the aspect ratio of an image
iv.contentMode=UIViewContentMode.ScaleAspectFit
iv.frame = CGRectMake (CGFloat(i)*width, 0, width, height);
scrollView.addSubview(iv)
}
