标签控制器

没拉控件，纯代码写

#import "ViewController.h"
#import "AViewController.h"
#import "BViewController.h"
#import "CViewController.h"
#import "DViewController.h"


@interface ViewController ()

@end

@implementation ViewController

    [super viewDidLoad];
    //

    self.view.backgroundColor = [UIColor whiteColor];

    CViewController *cController = [[CViewController alloc] init];
    DViewController *dController = [[DViewController alloc] init];

    UITabBarController *tabBarController = [[UITabBarController alloc] init];

    NSMutableArray *mArray = [NSMutableArray array];

    NSArray *array = @[aController, bController, cController, dController];

    NSArray *textArray = @[@"首页", @"消息", @"发现", @"我的"];

    NSArray *imageArray = @[[UIImage imageNamed:@"1"], [UIImage imageNamed:@"2"], [UIImage imageNamed:@"3"], [UIImage imageNamed:@"4"]];


    //标签控制器 嵌套 导航控制器
    for (int i = 0; i < array.count; i++) {
        UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:array[i]];

        UITabBarItem *tabBarItem = [[UITabBarItem alloc] initWithTitle:textArray[i] image:imageArray[i] selectedImage:imageArray[i]];

        navigationController.tabBarItem = tabBarItem;

        [mArray addObject:navigationController];
    }
