iOS项目社会化分享－微信分享，朋友圈分享，ios朋友圈

我只做了文字和图片分享功能

1. TARGETS - Info - URL Types

identifier -> weixin

URL Schemes -> 应用id

2.在AppDelegate.h 引入头文件

<pre name="code" class="objc">#import "WXApi.h"
{
/**
 *      WXSceneSession   分享到会话
 *      WXSceneTimeline  分享到朋友圈
 *      WXSceneFavorite  分享到我的收藏
 */
    enum WXScene _scene;
}

3.在AppDelegate.m

- (id)init{
    if(self = [super init]){
        _scene = WXSceneSession;
    }
    return self;
}
-(void) changeScene:(NSInteger)scene
{
    _scene = scene;
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
	
    // 其它代码

    // 向微信注册应用ID
    [WXApi registerApp:@"xxooxoxoxoxoxoxo"];
}

#pragma mark - 重写AppDelegate的handleOpenURL和openURL方法
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
    return [WXApi handleOpenURL:url delegate:self];
}

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

//<span style="font-family: Arial, Helvetica, sans-serif;">onReq 和 </span><span style="font-family: Arial, Helvetica, sans-serif;">onResp 可以不写</span><span style="font-family: Arial, Helvetica, sans-serif;">
</span>-(void) onReq:(BaseReq*)req
{
    if([req isKindOfClass:[GetMessageFromWXReq class]])
    {
        // 微信请求App提供内容， 需要app提供内容后使用sendRsp返回
        NSString *strTitle = [NSString stringWithFormat:@"微信请求App提供内容"];
        NSString *strMsg   = @"微信请求App提供内容，App要调用sendResp:GetMessageFromWXResp返回给微信";
        
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        alert.tag = 1000;
        [alert show];
        [alert release];
    }
    else if([req isKindOfClass:[ShowMessageFromWXReq class]])
    {
        ShowMessageFromWXReq* temp = (ShowMessageFromWXReq*)req;
        WXMediaMessage *msg = temp.message;
        
        //显示微信传过来的内容
        WXAppExtendObject *obj = msg.mediaObject;
        
        NSString *strTitle = [NSString stringWithFormat:@"微信请求App显示内容"];
        NSString *strMsg   = [NSString stringWithFormat:@"标题：%@ \n内容：%@ \n附带信息：%@ \n缩略图:%u bytes\n\n", msg.title, msg.description, obj.extInfo, msg.thumbData.length];
        
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        [alert show];
        [alert release];
    }
    else if([req isKindOfClass:[LaunchFromWXReq class]])
    {
        //从微信启动App
        NSString *strTitle = [NSString stringWithFormat:@"从微信启动"];
        NSString *strMsg   = @"这是从微信启动的消息";
        
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        [alert show];
        [alert release];
    }
}

-(void) onResp:(BaseResp*)resp
{
    if([resp isKindOfClass:[SendMessageToWXResp class]])
    {
        NSString *strTitle = [NSString stringWithFormat:@"发送媒体消息结果"];
        NSString *strMsg = [NSString stringWithFormat:@"errcode:%d", resp.errCode];
        
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        [alert show];
        [alert release];
    }
}

4.这是我写好的在微信会话和朋友圈分享文字或者图片的方法

直接调用就可以

#pragma mark - 微信, 朋友圈分享
#pragma mark 文字分享
- (void)sharedByWeChatWithText:(NSString *)WeChatMessage sceneType:(int)sceneType
{
    SendMessageToWXReq *req = [[[SendMessageToWXReq alloc] init]autorelease];
    req.text  = WeChatMessage;
    req.bText = YES;
    req.scene = sceneType;
    [WXApi sendReq:req];
}

#pragma mark 图片分享
- (void)sharedByWeChatWithImage:(NSString *)imageName sceneType:(int)sceneType
{
    WXMediaMessage *message = [WXMediaMessage message];
    [message setThumbImage:[UIImage imageNamed:imageName]];
    
    WXImageObject *ext = [WXImageObject object];
    NSString *filePath = [[NSBundle mainBundle] pathForResource:imageName ofType:@"png"];
    ext.imageData  = [NSData dataWithContentsOfFile:filePath];
    UIImage *image = [UIImage imageWithData:ext.imageData];
    ext.imageData  = UIImagePNGRepresentation(image);
    
    message.mediaObject = ext;
    
    SendMessageToWXReq *req = [[[SendMessageToWXReq alloc] init]autorelease];
    req.bText   = NO;
    req.message = message;
    req.scene   = sceneType;
    
    [WXApi sendReq:req];
}
