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 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. Set this property, you can let the click Status bar does not return to the top, but if we need to get him back to the top, the program does not respond to the operation, the solution just above the official document said, only if a host controller has a ScrollView and set this property to YES , the other scrollview.scrollstotop = no this will respond to this event, the principle is very simple, if there are 2 ScrollView, the system simply does not know which one you need to scroll to the top
Click the status bar to go back to the top
