1.进入微博开放平台的微连接，创建应用
2.获取App Key：App Secret：
3.设置授权回调页：取消授权回调页：
代码实现流程：
1.创建webView，设置代理，实现协议方法
2.首先访问授权接口Oauth2/authorize接口
https://api.weibo.com/oauth2/authorize?client_id=App Key&redirect_uri=回调页面的网址&display=mobile
3.构建请求
webView加载
_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.用户登录
在协议方法将要开始加载一个请求时
返回一个授权连接点击授权
授权服务器返回一个连接连接中包含（redirect_uri+code）
输出:http://www.new.com/?code=869f51c8f3dfd223824606808059fa50
请求授权完成后执行shouldStartLoadWithRequest判断是否返回code
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSLog(@"即将加载的请求路径-- %@",request.URL.absoluteURL);
NSString *str = request.URL.absoluteString;
NSRange range = [str rangeOfString:@"?code"];
//发现str中有没有code
if(range.location!=NSNotFound) {
//获取到code
//拆分找code的码
NSArray *array = [str componentsSeparatedByString:@"="];
NSString *code =[array lastObject];
NSLog(@"%@",code);
//创建请求管理类
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) {
}progress:^(NSProgress*_NonnulluploadProgress) {
}success:^(NSURLSessionDataTask*_Nonnulltask,id_NullableresponseObject) {
NSLog(@"responseObject ---> %@",responseObject);
[NSUserDefaults standardUserDefaults] setObject:<#(nullable id)#> forKey:<#(nonnull NSString *)#>
}failure:^(NSURLSessionDataTask*_Nullabletask,NSError*_Nonnullerror) {
NSLog(@"error -- %@",error);
}];
}
returnYES;
根据code构建一次请求
请求结束方法中获取access token
#import"ViewController.h"
#import"AFNetworking.h"
#define kAPPKey @"0000000000"
#define kAPP_Secret @"be7b7d29791adeca9000c7a174580d3e"
#define kRedirect_uri @"http://baidu.com"

/*
