2.创建应用

设置图片可以使用一个小工具，详情http://www.cnblogs.com/czq1989/p/5073586.html

一般审核几个小时就过了，审核通过之后也能删除掉这个应用

3.下载微信SDK

4.搭建开发环境

　　导入开发包中的文件

　　导入依赖库，官方说要导入四个

　　　　SystemConfiguration.framework

　　　　libz.tbd

　　　　libsqlite3.0.tbd

　　　　libc++.tbd

　　配置url type

5.写入相关代码

　　AppDelegate.m中

　　注意一点，重写的那两个方法现在不用了，适配一下低版本就可以了

　　导入WXApi.h

1 #import "WXApi.h"

　　遵守WXApiDelegate协议

1 @interface AppDelegate ()<WXApiDelegate>

　　在didFinishLaunchingWithOptions方法中进行App注册

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  [WXApi registerApp:@"################"];  return YES;}

　　重写appdelegate的两个方法

1 - (BOOL) application:(UIApplication *)application handleOpenURL:(NSURL *)url {2   return [WXApi handleOpenURL:url delegate:self];3 }

1 - (BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {2   return [WXApi handleOpenURL:url delegate:self];3 }

　　在ViewController.m里我们创建一个button，点击完成分享

 1 #import "ViewController.h" 2 #import "WXApi.h" 3  4 @interface ViewController ()<WXApiDelegate> 5  6 @end 7  8 @implementation ViewController 9 10 - (void)viewDidLoad {11   [super viewDidLoad];12   [self setButton];13   // Do any additional setup after loading the view, typically from a nib.14 }15 16 - (void)setButton {17   UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];18   [button setFrame:CGRectMake(120, 120, 120, 36)];19   [button setTitle:@"SharingTest" forState:UIControlStateNormal];20   [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];21   [self.view addSubview:button];22   [button addTarget:self action:@selector(sendMessage) forControlEvents:UIControlEventTouchUpInside];23 }24 25 - (void)sendMessage {26   SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];27   req.text = @"TigerCui的测试消息，请忽略";28   req.bText = YES;29   req.scene = WXSceneSession;30   [WXApi sendReq:req];31 }
