UISplitViewController 简单使用

    这种控制器只能用于iPad,它可以在iPad屏幕中显示两个不同的场景:在横向模式下,左边显示一个表,供用户选择;用户选择表中的元素后,详细视图将显示该元素的详细信息。如果iPad被旋转到纵向模式,表将消失,而详细视图将填满整个屏幕;要进行导航,用户可触摸一个工具栏按钮,这将显示一个包含表的弹出框。

    默认情况下,UISplitViewController的一端连接到一个受导航控制器(UINavigationController)管理的表视图(UITableViewController),这代表主场景;另一端连接到一个普通视图控制器(UIViewController),这代表详细场景。

    可以将主场景和详细场景替换为新的控制器,只需要删除默认的控制器,然后按住Control键,并从分割视图控制器对象拖曳到新的主场景或详细场景,再在Xcode提示时选择Relationship - masterViewController或Relationship - detailViewController。

    主场景和详细场景可以通过分割视图控制器互相访问,属性splitViewController包含一个名为viewControllers的数组。通过使用NSArray的方法lastObject,可获取该数组的最后一个元素(详细信息视图)。通过调用方法objectAtIndex,并将索引0传递给它,可获取该数组的第一个元素(主视图)。这样,两个视图控制器就可交换信息了。

    1, 在AppDelegate.h 中声明两个属性 代码如下 ,分别为UISplitViewController 和 右视图的Controller 其中  self.splitViewController.viewControllers = @[masterNavi,detilleNavi]; 数组中两个NavigationController 分别为左右视图

    #import#import "detilleViewController.h"@interface AppDelegate : UIResponder@property (strong, nonatomic) UIWindow *window;

    @property(nonatomic,strong)UISplitViewController * splitViewController;

    @property(nonatomic,strong)detilleViewController * detille;

    @end

    2,AppDelegate.m 中启动方法中代码如下所示

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Override point for customization after application launch.

    self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

    ViewController * masterVC = [[ViewController alloc]init];

    UINavigationController * masterNavi = [[UINavigationController alloc]initWithRootViewController:masterVC];

    self.detille= [[detilleViewController alloc]init];

    UINavigationController * detilleNavi = [[UINavigationController alloc]initWithRootViewController:self.detille];

    self.splitViewController = [[UISplitViewController alloc]init];

    [self.splitViewController setPresentsWithGesture:YES];

    self.splitViewController.viewControllers = @[masterNavi,detilleNavi];

    self.splitViewController.delegate = self.detille;

    self.window.rootViewController =self.splitViewController;

    [self.window makeKeyAndVisible];

    return YES;

    }

    3,以下代码为左视图tableView的构建,需要注意的是, 在tableViewCell 的didSelect方法中,不能去创建右边视图的Controller,右视图Controller 已经在AppDelegate中创建好了, 所以在这里我们只需获取到右视图的Controller即可

    #import "ViewController.h"#import "normalTableViewCell.h"#import "XWAFNetworkTool.h"#import "XWMain.h"#import "detilleViewController.h"#import "AppDelegate.h"@interface ViewController ()@property(nonatomic,strong)UITableView * tableView;

    @property(nonatomic,strong)NSMutableArray * cellArray;

    @property(nonatomic,strong)detilleViewController * detille;

    @end

    @implementation ViewController

    -(void)handleData

    {

    self.cellArray = [NSMutableArray array];

    [XWAFNetworkTool getUrl:@"http://api.guju.com.cn/v2/strategy/strategyList?userId=&count=50&start=0&" body:nil response:XWJSON requestHeadFile:nil success:^(NSURLSessionDataTask *task, id resposeObject) {

    NSArray * array = [resposeObject objectForKey:@"strategyList"];

    for (NSDictionary * dic in array) {

    XWMain * model = [[XWMain alloc]init];

    [model setValuesForKeysWithDictionary:dic];

    [self.cellArray addObject:model];

    }

    [self.tableView reloadData];

    } failure:^(NSURLSessionDataTask *task, NSError *error) {

    NSLog(@"%@",error);

    }];

    }

    -(void)createTableView

    {

    self.tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) style:UITableViewStylePlain];

    self.tableView.delegate =self;

    self.tableView.dataSource =self;

    [self.view  addSubview:self.tableView];

    [self.tableView registerClass:[normalTableViewCell class] forCellReuseIdentifier:@"reuse"];

    }

    - (void)viewDidLoad {

    [super viewDidLoad];

    [self createTableView];

    [self handleData];

    // Do any additional setup after loading the view, typically from a nib.

    }

    -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

    {

    return self.cellArray.count;

    }

    -(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

    {

    XWMain  * main = self.cellArray[indexPath.row];

    normalTableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"reuse"];

    cell.normal = main;

    return  cell;

    }

    -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

    {

    XWMain * main = self.cellArray[indexPath.row];

    AppDelegate * app =[UIApplication sharedApplication].delegate;

    detilleViewController * detille  =  app.detille;

    [detille setObject:main];

    }

    4,右视图中代码详见如下 其中 -(BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation 为协议方法用来设置横屏是否支持分屏

    #import "XWMain.h"

    #import "UIImageView+WebCache.h"

    @interface detilleViewController ()

    @property(nonatomic,strong)UILabel * titleLabel;

    @property(nonatomic,strong)UIImageView * imageV;

    @end

    @implementation detilleViewController

    -(void)setObject:(id)object

    {

    _object = object;

    [self loadDetilleView];

    }

    -(void)createSubView

    {

    self.titleLabel = [[UILabel alloc]init];

    self.titleLabel.frame = CGRectMake(0, 0, self.view.frame.size.width , 50);

    self.titleLabel.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2+100);

    self.titleLabel.backgroundColor = [UIColor yellowColor];

    self.titleLabel.textAlignment = NSTextAlignmentCenter;

    self.imageV = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];

    [self.view addSubview:self.imageV];

    [self.view addSubview:self.titleLabel];

    }

    -(void)loadDetilleView

    {

    if (!self.titleLabel) {

    [self createSubView];

    }

    if (self.object) {

    XWMain * main = self.object;

    NSLog(@" !!!%@",main.title);

    self.titleLabel.text = main.title;

    self.titleLabel.textColor = [UIColor blackColor];

    NSRange range = NSMakeRange(0, 3);

    NSString * imageUrl = [NSString stringWithFormat:@"http://image.gooju.cn/images/%@/9/%@_0_9-.jpg",[main.covorPhotoId.description substringWithRange:range],main.covorPhotoId.description];

    [self.imageV sd_setImageWithURL:[NSURL URLWithString:imageUrl]];

    NSLog(@"***!!!%@",self.titleLabel.text);

    }

    }

    -(BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation

    {

    return YES;

    }

    - (void)viewDidLoad {

    [super viewDidLoad];

    [self loadDetilleView];

    // Do any additional setup after loading the view.

    }

        self.views = [newSplitViewController.viewControllers lastObject];
        [self.views setcolor:@"fddsffds"];
