iOS8 Custom Fonts Crash

[alvinpb]

Having crashing issues with iOS8. Stacktrace below - this occurs when I navigate to a UITableView. Issue looks to be related to custom header fonts.

I am using a global CSS style to setup fonts through-out the app. - :not(button) > label { font-family: "PT Sans"; }

Removing this line - I don't get the crash. Looks to be a issue with pixate and UITableViewHeader labels in iOS8.

For anyone with this issue - can get around it with this.

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    if([view isKindOfClass:[UITableViewHeaderFooterView class]]){
        UITableViewHeaderFooterView *sectionHeaderView = (UITableViewHeaderFooterView *) view;
        sectionHeaderView.textLabel.styleMode = PXStylingNone;
    }
}

Same issue here. I'm getting around it by commenting out my style declaration in my CSS. 😕

Hopefully a fix comes from Apple soon.

Looks like building Pixate against iOS7.1 solves this one for me. I understand this is not a solution for everyone, but might help some people

[cliftonlabrum]

Yes, this is an iOS 8 issue.

generally, don't use tag like Label, View etc. Only stick to custom class should be fine.

You can probably close this issue since this is an iOS problem, not a Pixate one. Using a custom font without Pixate causes the same error on iOS 8.0 and 8.0.2. Since Apple has since fixed this problem, hopefully this is (mostly) behind us.
