Cancels the sticky effect of headers and footer in TableView

When I recently made a project, I encountered a bug, or limited personal ability, and thought for a long time didn't think the best way to go to reality.

So what's the problem?

First, when I set a header and a footer in Tabelview for the Not hungry section, when I slide the tableview, I find that the header and footer do not scroll with the cells in the TableView. And will live at the top of the bottom for a period of time, this effect, although good, but the above is not required by the function, so have to find a way to solve their own.

I remember sometimes the header does not stop, but why this time the header and footer are hidden?

Later found that the original set Tableview.tableheaderview = or Footerview time will not pause, it is of course, because this is part of the TableView, not part of the section.

I found a code like this on the Internet.

1 //Remove UITableView headerview stickiness (sticky)2 3- (void) Scrollviewdidscroll: (Uiscrollview *) ScrollView {4 5     if(ScrollView = =Self.tableview)6 7     {8 9CGFloat sectionheaderheight = -;//SectionheaderheightTen  One         if(Scrollview.contentoffset.y <= sectionheaderheight && scrollview.contentoffset.y >=0) { A  -Scrollview.contentinset = Uiedgeinsetsmake (-scrollview.contentoffset.y,0,0,0); -  the}Else if(Scrollview.contentoffset.y >=sectionheaderheight) { -  -Scrollview.contentinset = Uiedgeinsetsmake (-sectionheaderheight,0,0,0); -  +         } -  +     } A  at}

But his function set Headerview can not set Footerview, oneself also try to supplement Footerview implementation, but found that the technology is limited, so, you understand!

Finally saw a foreign great God wrote a article to find the following code

1-(void) Scrollviewdidscroll: (Uiscrollview *) ScrollView {2 3     if(ScrollView = =Self.tableview)4 5         {6 7UITableView *tableview = (UITableView *) ScrollView;8 9CGFloat sectionheaderheight = -;Ten  OneCGFloat sectionfooterheight = -; A  -CGFloat OffsetY =Tableview.contentoffset.y; -  the         if(OffsetY >=0&& OffsetY <=sectionheaderheight) -  -         { -  +Tableview.contentinset = Uiedgeinsetsmake (-offsety,0,-sectionfooterheight,0); -  +}Else if(OffsetY >= sectionheaderheight && OffsetY <= tableview.contentsize.height-tableview.frame.size.height -sectionfooterheight) A  at         { -  -Tableview.contentinset = Uiedgeinsetsmake (-sectionheaderheight,0,-sectionfooterheight,0); -  -}Else if(OffsetY >= tableview.contentsize.height-tableview.frame.size.height-sectionfooterheight && OffsetY < = Tableview.contentSize.height-tableview.frame.size.height) { -  inTableview.contentinset = Uiedgeinsetsmake (-offsety,0,-(Tableview.contentsize.height-tableview.frame.size.height-sectionfooterheight),0); -  to         } +  -     } the  *}

Note: Sectionheaderheight and sectionfooterheight are set according to the project.

Found basically done, and finally only need to set the corresponding padding can!
