1.進(jìn)入微博開放平臺(tái)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(shí)現(xiàn)流程：
1.創(chuàng)建webView衷旅，設(shè)置代理疾就，實(shí)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(qǐng)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(gè)請(qǐng)求時(shí)
返回一個(gè)授權(quán)連接點(diǎn)擊授權(quán)
授權(quán)服務(wù)器返回一個(gè)連接連接中包含（redirect_uri+code）
輸出:http://www.new.com/?code=869f51c8f3dfd223824606808059fa50
請(qǐng)求授權(quán)完成后執(zhí)行shouldStartLoadWithRequest判斷是否返回code
