2.注意点

注意适配
进行判断区分ipad与iphone

2.代码展示

AppDelegate.h

@property(nonatomic,strong)UISplitViewController *splitVc;//左侧的导航栏控制器

@property(nonatomic,strong)NSArray *detailNavArr;//存储ipad运行时，右侧详情视图导航控制器的数组

@property(nonatomic,strong)NSArray *detailArr; //存储iphone运行时，右侧需要进栈的视图控制器数组

AppDelegate.m

#import "mainTableViewController.h"//主控制器
#import "firstViewController.h"
#import "secondViewController.h"
#import "thirdViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    //主控制器
    mainTableViewController *main = [[mainTableViewController alloc]initWithStyle:UITableViewStylePlain];
    //导航栏

    //判断如果是ipad运行
    if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad) {
