constraints

[abalsam]

when using something like this:

 actionsheet_chat_buttons *chat_buttons = [[[NSBundle mainBundle]
                                              loadNibNamed:@"actionsheet_chat_buttons"
                                              owner:self options:nil]
                                             objectAtIndex:0];

    JGActionSheetSection *section_buttons = [JGActionSheetSection sectionWithTitle:nil message:nil contentView:chat_buttons];

to add a section with a contentView, I experienced layout problems. Added setting the constraints for the contentView after it had been added.
