方案一,添加UITableView的delegate:
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { // Remove seperator inset if ([cell respondsToSelector:@selector(setSeparatorInset:)]) { [cell setSeparatorInset:UIEdgeInsetsZero]; } // Prevent the cell from inheriting the Table View's margin settings if ([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]) { [cell setPreservesSuperviewLayoutMargins:NO]; } // Explictly set your cell's layout margins if ([cell respondsToSelector:@selector(setLayoutMargins:)]) { [cell setLayoutMargins:UIEdgeInsetsZero]; } }
方案二,对于自定义的Cell,添加以下代码:
- (UIEdgeInsets)layoutMargins { return UIEdgeInsetsZero; }
