} 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];
