上下两部分按钮组合，点击上部分的按钮，按钮移动到下部分；点击下部分中的按钮移动到上部分

页面组合底部是一个uiscrollview 上面两个view
view添加点击事件

 //点击分类设置view 实现分类按钮view的显示和隐藏
    self.showFenButton.userInteractionEnabled=YES;
    UITapGestureRecognizer *tapGesture=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(fenleiChanged)];
    [self.showFenButton addGestureRecognizer:tapGesture];

NSInteger senderSwitch=1;
-(void)fenleiChanged {
    if(senderSwitch==0) {
        btnView.hidden=false;
        [self.updown setImage:[UIImage imageNamed:@"arrow_down.png"]];
        senderSwitch=1;
    } else {
       btnView.hidden=true;
        [self.updown setImage:[UIImage imageNamed:@"arrow_right.png"]];
        senderSwitch=0;
    }
    
}

}

点击返回后重新加载主页面

//点击返回操作后
-(void)viewWillDisappear:(BOOL)animated{
     UIStoryboard *story=[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
    ScrollerViewController *mainList=[story instantiateViewControllerWithIdentifier:@"mainNavigation"];
    [self presentViewController:mainList animated:NO completion:nil];
}

两组分类差集，需要加mutableCopy


    self.selectedcategory =[[[CommenData alloc] getLocalSelectedFenlei]mutableCopy];
    self.allcategory =[[[CommenData alloc] getLocalAllFenlei]mutableCopy];
    [self.allcategory removeObjectsInArray:self.selectedcategory];
