1.首先是在微博发送消息,对于刚開始做weibo发送消息的刚開始学习的人会有一个误区,那就是会觉得须要授权后才干够发送消息。事实上发送消息仅仅须要几行代码就能够实现了,很easy,不须要先授权再发送消息,由于weibosdk已经帮我们封装好了。

(此情况须要用户安装client)

发送消息流程为:点击发送消息按键----SDK会自己主动帮我们推断用户是否安装了新浪微博client--假设未安装弹出安装提示----假设安装直接跳转到sina微博client进行发送----发送成功后自己主动跳回原应用程序。

1)在AppDelegate中注冊sdk, AppDelegate须要实现WeiboSDKDelegate

AppDelegate.h
@interface AppDelegate : UIResponder <UIApplicationDelegate, WeiboSDKDelegate>
{...
AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//注冊SDK
[WeiboSDK enableDebugMode:YES];
[WeiboSDK registerApp:kAppKey]; - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [WeiboSDK handleOpenURL:url delegate:self];
}

2)拼接消息对象WBMessageObject,并发送消息[WeiboSDK
sendRequest:request];

WBSendMessageToWeiboRequest *request = [WBSendMessageToWeiboRequest requestWithMessage:[self messageToShare]];
request.userInfo = @{@"ShareMessageFrom": @"SendMessageToWeiboViewController",
@"Other_Info_1": [NSNumber numberWithInt:123],
@"Other_Info_2": @[@"obj1", @"obj2"],
@"Other_Info_3": @{@"key1": @"obj1", @"key2": @"obj2"}};
// request.shouldOpenWeiboAppInstallPageIfNotInstalled = NO; [WeiboSDK sendRequest:request];//这句就能够发送消息了,不须要先授权
- (WBMessageObject *)messageToShare
{
WBMessageObject *message = [WBMessageObject message]; if (self.textSwitch.on)
{
message.text = @"測试通过WeiboSDK发送文字到微博!";
} if (self.imageSwitch.on)
{
WBImageObject *image = [WBImageObject object];
image.imageData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image_1" ofType:@"jpg"]];
message.imageObject = image;
} if (self.mediaSwitch.on)
{
WBWebpageObject *webpage = [WBWebpageObject object];
webpage.objectID = @"identifier1";
webpage.title = @"分享网页标题";
webpage.description = [NSString stringWithFormat:@"分享网页内容简单介绍-%.0f", [[NSDate date] timeIntervalSince1970]];
webpage.thumbnailData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image_2" ofType:@"jpg"]];
webpage.webpageUrl = @"http://sina.cn? a=1";
message.mediaObject = webpage;
} return message;
}

重要:假设程序发送完消息无法跳回原应用的话是由于在plist文件里没有配置URL Types,appKey在你的新浪开发人员帐号里有。

2.授权。通过授权我们能够在用户未安装client的情况下关注指定微博。

授权主要是为了得到:userID,accessToken。有了accessToken我们就能够訪问新浪weibo的API了http://open.weibo.com/wiki/%E5%BE%AE%E5%8D%9AAPI

response.userInfo对象就是我们要的东西
