iOS 微信分享

1.注册微信开放平台账号：https://open.weixin.qq.com

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 }
