This is an attribute scrollstotop of the ScrollView inherited by TableView.
The official note is this:
When the user taps the status bar, the scroll view beneath the touch which are closest to the status bar would be Scrolle D to top, if it's ' Scrollstotop ' property is YES, it delegate does not return No. from ' Shouldscrollviewscrolltoto P ', and it isn't already at the top.
On the IPhone, we execute this gesture only if there's one on-screen scroll view with ' scrollstotop ' = = YES. If more than one is found, none would be scrolled.
@property (nonatomic) BOOL scrollstotop; Default is YES.
The following conditions are required to implement this feature:
1. There is only one scrollview or tableview on the screen.
2. Its Scrollstotop property is set to Yes and the default is yes.
To disable this feature, set the Scrollstotop property to No.
