ios - addTarget:action:forControlEvents: unrecognized selector sent to instance - uibutton in uitablecell -
* edit: sorry, realised - code working fine, until made table have 3 sections. when single section section headings evrything worked fine when scrolling. have theree sections crashes when scrolling.*
i'm adding button uitablecell. crash occurs when table contents extend beyond table height, , table scrolled extreme bottom.
from error looks if uibutton isn't being created, reports jobscell instead...
also layout in custom uitablecell goes awry. looks jobscell class isn't being initiated cells need reused , displayed on screen?
