1.首先在mac上安装node和npm

可参考mac上安装nodejs和npm

2. 查看node和npm版本号

node -v 和npm -v

3.安装weex-toolkit

sudo npm install -g weex-toolkit
查看是否安装成功
weex --version

4.安装CocoaPods

可参考看一遍就会的CocoaPods的安装和使用教程

5.用xcode新建一个空项目，并通过终端运行pod init 命令，以便生成Podfile文件，如图

Snip20171214_1.png

6.编辑podfile文件，在编辑前需要通过pod search WeexSdk，查看WeexSdk最新版本号，

编辑内容如下：

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
#inhibit_all_warnings!

def common
    pod 'WeexSDK', '0.17.0'
    pod 'WXDevtool', '0.15.3'
    pod 'SDWebImage', '3.7.5'
    pod 'SocketRocket', '0.4.2'
    pod 'ATSDK-Weex', '0.0.1'
    
    # WeexGcanvas is added by Weex Plugin, more info at https://market.dotwe.org/ext/list.htm
    pod 'WeexGcanvas'
end

target 'weexdemo' do
    common
end

执行命令pod install

7.新建bundlejs文件夹，然后将webstrom生成的js文件拷贝进去

8.修改AppDelegate

.h文件
#import <UIKit/UIKit.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@end
.m文件
#import "AppDelegate.h"
#import <WeexSDK/WeexSDK.h>
#import "ViewController.h"
@interface AppDelegate ()

@end

@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    self.window.backgroundColor = [UIColor whiteColor];
    self.window.rootViewController = [[WXRootViewController alloc] initWithRootViewController:[ViewController new]];
    [self.window makeKeyAndVisible];
    
    [WXAppConfiguration setAppGroup:@"jwDemo"];
    [WXAppConfiguration setAppName:@"weexPageDemo"];
    [WXAppConfiguration setAppVersion:@"1.0.0"];
    
    //init sdk enviroment
    [WXSDKEngine initSDKEnviroment];
    [WXLog setLogLevel: WXLogLevelAll];//输出日志
    return YES;
    
}


- (void)applicationWillResignActive:(UIApplication *)application {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}


- (void)applicationDidEnterBackground:(UIApplication *)application {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}


- (void)applicationWillEnterForeground:(UIApplication *)application {
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}


- (void)applicationDidBecomeActive:(UIApplication *)application {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}


- (void)applicationWillTerminate:(UIApplication *)application {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}


@end

9.修改ViewController

.h文件
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@property (nonatomic, copy) NSString *url;
@end
.m文件
#import "ViewController.h"
#import <WeexSDK/WXSDKInstance.h>
@interface ViewController ()
@property (nonatomic, readwrite, strong) WXSDKInstance *instance;
@property (nonatomic, weak) UIView *weexView;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.view setBackgroundColor:[UIColor whiteColor]];
    
    //默认加载的地址为本地路径的bundlejs/index.js
    if (!self.url) {
        self.url = [[NSBundle mainBundle] pathForResource:@"bundlejs/index" ofType:@"js"];
    }
    [self render];//weex将js渲染成weex页面。
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
- (void)render{
    NSURL *URL = [[NSURL alloc] initFileURLWithPath:self.url];
    
    CGFloat width = self.view.frame.size.width;
    [_instance destroyInstance];
    _instance = [[WXSDKInstance alloc] init];
    _instance.viewController = self;
    _instance.frame = CGRectMake(0, 64, width, self.view.frame.size.height);
    
    __weak typeof(self) weakSelf = self;
    _instance.onCreate = ^(UIView *view) {
        [weakSelf.weexView removeFromSuperview];
        weakSelf.weexView = view;
        [weakSelf.view addSubview:weakSelf.weexView];
    };
    
    NSString *randomURL = [NSString stringWithFormat:@"%@?random=%d",URL.absoluteString,arc4random()];
    [_instance renderWithURL:[NSURL URLWithString:randomURL] options:@{@"bundleUrl":URL.absoluteString} data:nil];
}

- (void)dealloc{
    [_instance destroyInstance];
}

@end
