UIScrollview scrolling stuck at the bottom of its content size after update its frame
Here you can see, I have stuck problem with UIScrollview scrolling at the bottom of its content size after update its frame.
I have tried to remove 2 lines following code:
This one:
scrBuilds.frame = CGRect(x: 0, y: 140, width: scrBuilds.frame.width, height: self.view.frame.height - 140)
And this one:
scrBuilds.frame = CGRect(x: 0, y: 235, width: scrBuilds.frame.width, height: self.view.frame.height - 235)
After removed these 2 lines, I couldn't see the stuck issue but the frame of scrBuilds not updated efficiently. Here is my code.
func scrollViewDidScroll(_ scrollView: UIScrollView) {
let offset = self.scrBuilds.contentOffset.y
if offset > 0 {
if offset < 60 {
filterView.frame = CGRect(x: 0, y: 20 - offset, width: filterView.frame.width, height: 60)
self.scrCategory.transform = CGAffineTransform(scaleX: 1, y: 1)
scrCategory.frame = CGRect(x: 0, y: 80 - offset, width: scrCategory.frame.width, height: 155)
}
if offset >= 60 && offset < 95 {
filterView.frame = CGRect(x: 0, y: -40, width: filterView.frame.width, height: 60)
self.scrCategory.transform = CGAffineTransform(scaleX: (215 - offset) / 155, y: (215 - offset) / 155)
scrCategory.frame = CGRect(x: 0, y: 20, width: scrCategory.frame.width, height: 215 - offset)
}
if offset >= 95 {
filterView.frame = CGRect(x: 0, y: -40, width: filterView.frame.width, height: 60)
self.scrCategory.transform = CGAffineTransform(scaleX: 120 / 155, y: 120 / 155)
scrCategory.frame = CGRect(x: 0, y: 20, width: scrCategory.frame.width, height: 120)
scrBuilds.frame = CGRect(x: 0, y: 140, width: scrBuilds.frame.width, height: self.view.frame.height - 140)
}else {
scrBuilds.frame = CGRect(x: 0, y: 235 - offset, width: scrBuilds.frame.width, height: self.view.frame.height - 235 + offset)
}
}else {
filterView.frame = CGRect(x: 0, y: 20, width: filterView.frame.width, height: 60)
self.scrCategory.transform = CGAffineTransform(scaleX: 1, y: 1)
scrCategory.frame = CGRect(x: 0, y: 80, width: scrCategory.frame.width, height: 155)
scrBuilds.frame = CGRect(x: 0, y: 235, width: scrBuilds.frame.width, height: self.view.frame.height - 235)
}
}
I want to get scrBuilds never stuck and its frame updated efficiently. Please help me for it.
