本文介绍了一种iOS应用中实现TabBarController热更新的方法。通过检查应用文档目录下的Framework文件来决定是否使用HotUpdateControl类进行页面控制器的加载。若未发现对应的Framework，则创建默认的导航控制器。

核心功能在这里，其余步骤其实在另外一个FrameWorks工程，那边做的事情就是建立了一个HotUpdateControl对象内部有一个方法getVcs 可以返回一个UIViewController数组

#import "TabController.h"  
//#import <HotUpdateMudel/HotUpdateControl.h>  
@interface TabController ()  

@end  

@implementation TabController  

-(instancetype)initWithCoder:(NSCoder *)aDecoder{  
    if (self = [super initWithCoder:aDecoder]) {  
        NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];  
        NSArray* arrFramework = [self getFilenamelistOfType:@"framework"  fromDirPath:documentDirectory];  
        NSLog(@"%@",arrFramework);  
        if (arrFramework.count==0) {  
             NSArray * arrTitle = @[@"首页",@"广场",@"朋友圈",@"我的",@"设置"];  
            NSMutableArray * arrVcs = @[].mutableCopy;  
            for (int i=0; i<arrTitle.count; i++) {  
                UIViewController * vcRoot = [[UIViewController alloc]init];  
                vcRoot.title = arrTitle[i];  
                vcRoot.view.backgroundColor = [UIColor whiteColor];  
                UINavigationController * navi = [[UINavigationController alloc]initWithRootViewController:vcRoot];  
                [arrVcs addObject:navi];  
            }  
            [self setViewControllers:arrVcs animated:YES];  

        }else{  

            NSString *bundlePath = [NSString stringWithFormat:@"%@/%@",documentDirectory,[arrFramework lastObject]];  

            if (![[NSFileManager defaultManager] fileExistsAtPath:bundlePath]) {  
                NSLog(@"file not exist ,now  return");  
                return self;

                return self;  
            }  
            NSObject *bundleObj = [loadClass new];              
            NSArray * arrVc = [bundleObj performSelector:@selector(getVcs)];  

            NSMutableArray * arrVcs = @[].mutableCopy;
