It is crashed in the Main thread, and what I do is create a JGActionSheetSection. The crash seems to happen at

button.titleLabel.font = font;

button is released when label is set to button(right?). My Project enables ARC, and I can't find any memory problem. Could you take a look?

[JonasGessner]

Are you passing a valid value as button style?

[scorpiozj]

what I call is like:
JGActionSheetSection *sectionNonFA = [JGActionSheetSection sectionWithTitle:nil message:nil buttonTitles:actionArray buttonStyle:JGActionSheetButtonStyleDefault];

where actionArray is a array of String.

I got a similar crash
Once set font to btn.titleLabel.font crash coming
