I have ViewController with UIScrollView, some UIImages and UIButtons. In the Storyboard I set the size of UIScrollView to: width: 320, height: 570
I want to change Contentsize of my UIScrollView when the ViewController was loaded.
I added side in the viewDidLoad:
scrlMain.contentSize = CGSize(width: 320,height: 790)
And also I added code in the viewDidLayoutSubviews:
self.scrlMain.translatesAutoresizingMaskIntoConstraints = true
But my UIScrollView is still the last size = 570. I can't use viewDidAppear because, when I press the button, it need it to change color. When it has changed color, my UIScrollView moves to up.
What did I do wrong?
All code:
override func viewDidLoad() {
super.viewDidLoad()
scrlMain.delegate = self
scrlMain.contentSize = CGSizeMake(320, 790)
}
override func viewDidLayoutSubviews() {
self.scrlMain.translatesAutoresizingMaskIntoConstraints = true
self.scrlMain.contentSize = CGSize(width: self.scrlMain.frame.width, height: 60.0 + 5 * (self.scrlMain.frame.width / 16.0 * 5.0));
}
there was an error in the this function:
override func viewDidLayoutSubviews() {
self.scrlMain.translatesAutoresizingMaskIntoConstraints = true
self.scrlMain.contentSize = CGSize(width: self.scrlMain.frame.width, height: 60.0 + 5 * (self.scrlMain.frame.width / 16.0 * 5.0));
}
I delete this code:
self.scrlMain.contentSize = CGSize(width: self.scrlMain.frame.width, height: 60.0 + 5 * (self.scrlMain.frame.width / 16.0 * 5.0));
And all was right
