When setting up a UITableView with a specific number of rows, you might notice extra separator lines or blank cells below the filled rows. This article will guide you on how to remove these extra separators efficiently.
Using Interface Builder (iOS 9+)
For those using Interface Builder, the process is quite simple:
- Drag a UIView into your UITableView as a footer.
- In the storyboard, position it below your custom cells. You may prefer to name it “footer”.
- Set the footer view’s height to zero to ensure it doesn’t affect the layout.
Note: Adjusting the height of the footer can influence how the bottom bounce of the table is handled.
Programmatic Approach
If you prefer to handle this programmatically, here are the steps for Swift and Objective-C:
Swift
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.tableFooterView = UIView()
}Objective-C
- (void)viewDidLoad {
[super viewDidLoad];
// This will remove extra separators from tableview
self.tableView.tableFooterView = [UIView new];
}Alternatively, you can set the frame to CGRectZero:
self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];Historical Approach in iOS
For older versions of iOS, you can add the following methods to your table view controller:
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
// This will create an "invisible" footer
return CGFLOAT_MIN;
}
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
return [UIView new];
}Practical Example
Here’s a practical example of implementing the solution in Swift:
override func viewDidLoad() {
super.viewDidLoad()
// Remove extra separators
tableView.tableFooterView = UIView()
}Conclusion
Removing extra separators from a UITableView can be done easily using both Interface Builder and programmatic approaches. By setting a UIView as the tableFooterView, you can ensure a cleaner and more professional look for your table views.
