App Crashing at line 317 in PrettyTableViewCell.m (SIGSEGV)

[timschroeder]

Hello everyone,

I use PrettyKit in one of my apps at the App Store. I have 500 active users and the app crash by some people (iPad 2, 3, 4 / iOS 5.1.1 - iOS 6.1.3).

0x00082903 -PrettyTableViewCellBackground drawRect:

Has everyone else the problem? I can't simulate the problem on my test devices.

[Amnell]

I've not had this problem. You don't have a complete crash log?

[timschroeder]

Yes. The problem is that the app crash direct after launch by the users and they can reproduce it. It worked on my 4 test iPads without any problem.

I'm using PrettyKit at a project with ARC and the -fno-objc-arc flag for the PrettyKit files.

[Amnell]

You're not able to symbolicate it to increase readability?

[timschroeder]

It's the symbolicated crash report. But the GitHub editor change this line.

1 NewApp 0x00082903 -PrettyTableViewCellBackground drawRect:

I can't get more information about the crash.

[timschroeder]

Any ideas? I think it must be in this snip of code:

• (void) drawRect:(CGRect)initialRect { CGRect rect = [self innerFrame:initialRect];

  [self drawBorder:rect shadow:self.cell.dropsShadow];

  [self drawBackground:rect];

  switch (self.cell.position) { case PrettyTableViewCellPositionAlone: case PrettyTableViewCellPositionBottom: if (self.cell.tableViewIsGrouped) { break; } default: [self drawLineSeparator:CGRectMake(rect.origin.x, rect.origin.y, rect.size.width, rect.size.height)]; break;

  } }

---

The problem is I can't reproduce the crash. Only a few customers are able to do that but they won't give me their UDID of the device.
