我是靠谱客的博主羞涩金毛，这篇文章主要介绍iOS9苹果将原http协议改成了https协议的方法，现在分享给大家，希望可以做个参考。

解决方法：

在info.plist 加入key

复制代码

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

下面给大家介绍ios中http 和https 协议的访问

最近做个项目，开始采用的是HTTP协议实现客户端和服务器端的交互，后来需要改成HTTPS协议。在修改的过程中发现了一些问题，解决方案如下：

HTTP：

NSString *urlString =[NSString stringWithFormat:@"https://127.0.0.1/default.aspx?USER=%@",@"111"];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"GET"];
NSHTTPURLResponse* urlResponse = nil;
NSError *error = [[NSError alloc] init];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
NSMutableString *result = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(@"The result string is :%@",result);

HTTPS

//设置请求方式为get
[request setHTTPMethod:@"GET"];
//添加用户会话id

//连接发送请求
finished = false;
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
//堵塞线程，等待结束

}
} 
NSLog(@"get the whole response");
//[receivedData setLength:0];
}
//处理数据 
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
