This question appeared many times, each time is the Niang, the command +c,command + V, has written to forget, today hereby records:

On the iOS8 [TableView Setseparatorinset:Uiedgeinsetsmake(0,0,0,0)]; not working.

You can add the following code to the TableView creation location:　　

if ([Self.tableview respondstoselector: @selector (setseparatorinset:)]) {          [Self.tableview setseparatorinset: Uiedgeinsetsmake (0,0,0,0)];      }             if ([Self.tableview respondstoselector: @selector (setlayoutmargins:)]) {          [Self.tableview setlayoutmargins: Uiedgeinsetsmake (0,0,0,0)];      }  

Then add the following code to the UITableView proxy method:

-(void) TableView: (UITableView *) TableView Willdisplaycell: (UITableViewCell *) cell Forrowatindexpath: ( Nsindexpath *) indexpath  {      if  ([Cell Respondstoselector: @selector (setseparatorinset :)]) {          [cell Setseparatorinset:uiedgeinsetszero];      }             if ([Cell Respondstoselector: @selector (setlayoutmargins:)]) {          [cell Setlayoutmargins:uiedgeinsetszero];      }  }
