I have got this error too |
|
Thanks for your feedback! May I ask what version of SegementSlide you used? |
|
@Jiar I am currently using version 3.0.1. |
|
@HyunjoonKo @lumanmann I run the Example under the same environment, but no problem is found. It is better to have a Demo that can reproduce the problem, otherwise it is difficult to troubleshoot the problem. |
|
I have got the same error from Firebase Crashlytics report. |
|
So as I... Is there anyone who solved this problem? |
|
@hansolnoh95 Not yet. It does not appear in the development environment, but many reports are still reported in Crashlytics and Xcode crash reports. |

@Jiar internal func childScrollViewDidScroll(_ childScrollView: UIScrollView) {
defer {
scrollViewDidScroll(childScrollView, isParent: false)
}
let parentContentOffsetY = scrollView.contentOffset.y // 0.0
let childContentOffsetY = childScrollView.contentOffset.y // 0.0
switch innerBouncesType {
case .parent:
if !canChildViewScroll {
childScrollView.contentOffset.y = 0 // Thread 1: EXC_BAD_ACCESS (code=2, address=0x16b8e3ff0)
} else if childContentOffsetY <= 0 {
canChildViewScroll = false
canParentViewScroll = true
}
case .child:
if !canChildViewScroll {
childScrollView.contentOffset.y = 0
} else if childContentOffsetY <= 0 {
if parentContentOffsetY <= 0 {
canChildViewScroll = true
}
canParentViewScroll = true
} else {
if parentContentOffsetY > 0 && parentContentOffsetY < headerStickyHeight {
canChildViewScroll = false
}
}
}
}The problem was solved when I tried to fix it as follows: // ...
case .parent:
if !canChildViewScroll, childScrollView.contentOffset.y != childContentOffsetY {
childScrollView.contentOffset.y = 0
} else if childContentOffsetY <= 0 {
canChildViewScroll = false
canParentViewScroll = true
}
// ... |
how can you fix it, can you share the why? |

Hi @skeyboy You can see the fixed source code here: Install with CocoaPods: If |
A lot of error reports came into my app's Crashlytics. Please check.
