iOS上的侧边栏菜单实现如Facebook？

Question

我想在iOS 6中创建Facebook iPhone应用程序中的侧栏菜单.

我该如何创建它？

我是这个iPhone开发的新手.

请给我一些指示或告诉我一些基本的教程,我可以一步一步地实现它.

Answer 1

我们可以轻松地自己做.它是如此容易.

我在这里解释的方法正在我的应用程序中使用.

目的:

在标题栏中按下按钮时,侧栏必须从左侧滑入和滑出.

脚步:

1)创建一个视图控制器(home)和两个nsObject类(侧栏,主)

2)在视图控制器上添加工具栏

3)在侧边栏中(左侧视图):

i)根据项目需要添加视图,在所需的侧边栏宽度上构建一个uiview(将在vc上添加)

ii)然后创建按钮并将其作为属性,因为它的目标事件必须在视图控制器中发生

iii)你必须有两个CGRects用于按钮和结果视图一个CGrect用于扩展状态另一个CGrect用于折叠

iv)只要按钮被cocerned,它的x是sidebarwidth-buttonwidth用于展开状态,它的x是0 + buttonwidth用于折叠状态,就视图而言,对于展开状态,x为0,对于折叠状态,x为-sidebarwidth

4)在主要(右侧视图):

i)构建一个UIView并将其添加到UiscollView(将在vc上添加)

ii)UIView将有两个用于UIscrollView的CGREct,一个用于展开,一个用于折叠

iii)UIview的x是0 y是0宽度是1024而高度是726(vc上的横向视图高度 - 工具栏宽度)

iv)在折叠时间uIscrollview的x是sidebarwidth y是42(vc'tool bar height),宽度是1024-sidebarwidth,高度与uiview的相同

v)在扩展时间Uiscrollview的x为0,宽度为1024

vi)Uiscrollview内容大小总是应该是1024,726,因为如果缩小大小,我们需要滚动

5)在视图控制器(主页)中:

i)在家中添加侧栏和主栏

ii)然后为侧栏中的按钮添加和事件,然后将其添加到工具栏上usign addsubview方法

iii)在按钮触摸事件中调用内部的切换事件

 -(void)OnCollapsibleExtenderTouchUpInside
{
   [UIView animateWithDuration:1.0 animations:^{

    [sideBarObj ToggleVuPosition];

    [mainVuObj ToggleVuSize];

 }];

}

以下代码适用于我..(我只是为了自己的缘故重命名了一些字段)

要更好地理解以下代码:

1)View控制器名称为Home,侧栏名称为侧栏,右侧区域名称为Main

2)我已经编写了横向编码...你可以自定义它的肖像也可以使用它.

侧栏:

#import <Foundation/Foundation.h>

@interface SideBar : NSObject
{
UIView *vuSideBar;

UIScrollView *scrollVuSideBar;

UIImageView *imgProfilePicture;

CGRect rectVuSideBar,rectExpandedScrollVuSideBar,rectCollapsedScrollVuSideBar,rectImgProfilePicture,rectExpandedBtnCollapsibleExtender,rectCollapsedBtnCollapsibleExtender;

 int sideBarWidth,sideBarHeight;
}

@property(strong,nonatomic)UIButton *btnCollapsibleExtender;

-(id)initWithParent:(UIView *)vuParent andToolBar:(UIToolbar *)toolBarParent;

-(void)ToggleVuPosition;

@end

边栏实施:

 #import "SideBar.h"

@interface  SideBar()

-(void)initOtherIvars;

-(void)AddViewsOnHierarchy;

-(void)AddToParentVu:(UIView *)ParentVu;

   [imgProfilePicture setImage:imgDefaultProfile];

  }

 -(void)AddViewsOnHierarchy
{
   NSLog(@"AddViewsOnHierarchy");

   [vuSideBar addSubview:imgProfilePicture];

   [scrollVuSideBar addSubview:vuSideBar];
 }

 -(void)AddToParentVu:(UIView *)ParentVu

  [ParentVu addSubview:scrollVuSideBar];
 }

 -(void)AddToParentToolbar:(UIToolbar *)ParentToolBar
 {
  NSLog(@"AddToParent toolbar");

 [ParentToolBar addSubview:btnCollapsibleExtender];
 }

 -(void)ToggleVuPosition
 {
 switch ((int)scrollVuSideBar.frame.origin.x)
 {
     case 0:

        scrollVuSideBar.frame=rectCollapsedScrollVuSideBar;

             btnCollapsibleExtender.frame=rectCollapsedBtnCollapsibleExtender;

        break;

      default:

        scrollVuSideBar.frame=rectExpandedScrollVuSideBar;

     [UIView animateWithDuration:1.0 animations:^{

    [sideBarObj ToggleVuPosition];

    [mainVuObj ToggleVuSize];

 }];

}

@end

上面的代码可以通过不使用main进一步定制,并在Home视图控制器中添加代码,同样可以避免单边栏的单独类,并将其包含在home viewcontroller本身中.

当用户按下侧栏中的按钮时,对于主视图中的更改,您可以使用协议代理,或者我们可以将侧栏中的按钮作为属性并在视图控制器中添加事件.

我希望这有帮助.

有很多实现，但我会建议您JTRevealSidebarDemo它简单且易于定制，您也可以使用ViewDeck或JASidePanels。JASidePanels 文档齐全，并为像您这样的新开发人员提供了基本示例！
