1.進(jìn)入微博開放平臺的微連接，創(chuàng)建應(yīng)用
2.獲取App Key：App Secret：
3.設(shè)置授權(quán)回調(diào)頁：取消授權(quán)回調(diào)頁：
代碼實現(xiàn)流程：
1.創(chuàng)建webView，設(shè)置代理，實現(xiàn)協(xié)議方法
2.首先訪問授權(quán)接口Oauth2/authorize接口
https://api.weibo.com/oauth2/authorize?client_id=App Key&redirect_uri=回調(diào)頁面的網(wǎng)址&display=mobile
3.構(gòu)建請求
webView加載
_webView= [[UIWebViewalloc]initWithFrame:self.view.bounds];
_webView.delegate=self;
[self.view addSubview:_webView];
NSURL*url = [NSURL URLWithString:[NSString stringWithFormat:@"https://api.weibo.com/oauth2/authorize?client_id=%@&redirect_uri=%@&display=mobile",kAPPKey,kRedirect_uri]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
4.用戶登錄
在協(xié)議方法將要開始加載一個請求時
返回一個授權(quán)連接點擊授權(quán)
授權(quán)服務(wù)器返回一個連接連接中包含（redirect_uri+code）
輸出:http://www.new.com/?code=869f51c8f3dfd223824606808059fa50
請求授權(quán)完成后執(zhí)行shouldStartLoadWithRequest判斷是否返回code
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSLog(@"即將加載的請求路徑-- %@",request.URL.absoluteURL);
NSString *str = request.URL.absoluteString;
NSRange range = [str rangeOfString:@"?code"];
//發(fā)現(xiàn)str中有沒有code
if(range.location!=NSNotFound) {
//獲取到code
//拆分找code的碼
NSArray *array = [str componentsSeparatedByString:@"="];
NSString *code =[array lastObject];
NSLog(@"%@",code);
//創(chuàng)建請求管理類
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSString *urlStr =@"https://api.weibo.com/oauth2/access_token";
NSDictionary *dic = @{@"client_id":kAPPKey, @"client_secret":kAPPSecret, @"grant_type":@"authorization_code", @"code":code, @"redirect_uri":kRedirect_uri};
manager.responseSerializer.acceptableContentTypes= [NSSet setWithObject:@"text/plain"];
[manager POST:urlStrparameters:dicconstructingBodyWithBlock:^(id_NonnullformData) {

根據(jù)code構(gòu)建一次請求
