分割器

分割器目前只支持iPhone6 plus、pad和刚发布的iPhone6s plus。

建立左右两个view。在根视图中：

#import "AppDelegate.h"
#import "LeftViewController.h"
#import "RightViewController.h"
@interface AppDelegate ()
{
    //声明分割器
    UISplitViewController *svc;
    LeftViewController *viewL;
    RightViewController *viewR;
    UINavigationController *ncL;
    UINavigationController *ncR;
}
@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    
    //创建分割器及两个视图
    viewL=[[LeftViewController alloc] init];
    ncL=[[UINavigationController alloc] initWithRootViewController:viewL];
    viewR=[[RightViewController alloc] init];
    ncR=[[UINavigationController alloc] initWithRootViewController:viewR];

    svc=[[UISplitViewController alloc] init];
    svc.delegate=self;
    //设置分割器分割的视图
    svc.viewControllers=@[ncL,ncR];
    self.window.rootViewController=svc;

    return YES;
}
#pragma mark - 实现分割器协议函数
-(BOOL)splitViewController:(UISplitViewController *)splitViewController showViewController:(UIViewController *)vc sender:(id)sender{
    return NO;
}
-(BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation{
    return NO;
}

注意：左边的视图坐标及大小正常取。右边的视图要自适应(判断横屏还是纵屏)

    tvR=[[UITableView alloc] init];
    //判断横屏还是纵屏
    if (self.interfaceOrientation==UIInterfaceOrientationLandscapeLeft || self.interfaceOrientation==UIInterfaceOrientationLandscapeRight) {
        //横屏
        tvR.frame=CGRectMake(0, 0, 1024-320, 768);
    }else{
        //纵屏
        tvR.frame=CGRectMake(0, 0, 768, 1024);
    }
