Extra padding above table view headers in iOS 15

Question

How to change the extra padding above UITableView section headers that has started to appear in iOS 15?

Answer 1

Since iOS 15, UITableView contains a new property called sectionHeaderTopPadding which specifies the amount of padding above each section header.

tableView.sectionHeaderTopPadding = 0.0

Note: This applies only to the UITableView.Style.plain.

Answer 2

For applying changes everywhere in app

if #available(iOS 15.0, *) {
    UITableView.appearance().sectionHeaderTopPadding = 0.0
}

preferably in AppDelegate.

Answer 3

Put this in the main didFinishLaunchingWithOptions to fix it globally:

if (@available(iOS 15.0, *))
{
    UITableView.appearance.sectionHeaderTopPadding = 0;
}

Answer 4

This is the new Instance Property of UITableView in iOS 15. https://developer.apple.com/documentation/uikit/uitableview/3750914-sectionheadertoppadding

sectionHeaderTopPadding which specifies the amount of padding above each section header.

To remove the padding use below code

if #available(iOS 15.0, *) {
    self.tableView.sectionHeaderTopPadding = 0.0 
}

To remove the padding from everywhere in the app, use below code in AppDelegate

if #available(iOS 15.0, *) {
    UITableView.appearance().sectionHeaderTopPadding = 0.0
}

Answer 5

A global way for obj-c:

if (@available(iOS 15.0, *)) {
    [[UITableView appearance] setSectionHeaderTopPadding:0.0f];
}
