导航栏上的那64个点

之前一直说用

    self.automaticallyAdjustsScrollViewInsets =NO; 

    

    self.navigationController.automaticallyAdjustsScrollViewInsets =NO;

现在加上这两句也不顶用了

得加上下面的

 if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {

        self.edgesForExtendedLayout =UIRectEdgeNone;

    }

或者这句

      self.navigationController.navigationBar.translucent = NO;
