報(bào)錯(cuò)

Warning once only: Detected a case where constraints ambiguously

suggest a height of zero for a tableview cell's content view. We're

considering the collapse unintentional and using standard height

instead.

加這句話就好了

-(CGFloat )tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{

return 44;

}
