UITableViewCell Separator disappearing in iOS7

Question

I have some strange issue with UITableView only in iOS 7.

UITableViewCellSeparator disappears above the first row and below the last row. S

Answer 1

I solve this problem in another way: add a layer that its height is 0.5px and its color is lightgray into tableview.tableFooterView as its sublayer.

the code is just like this:

UIView *tableFooterView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 70)];
CALayer *topSeperatorLine = [CALayer layer];
topSeperatorLine.borderWidth = 0.5f;
topSeperatorLine.borderColor = [UIColor lightGrayColor].CGColor;
topSeperatorLine.frame = CGRectMake(0, 0, 320, 0.5f);
[tableFooterView.layer addSublayer:topSeperatorLine];
self.tableView.tableFooterView = tableFooterView;
