iOS 9 NSURLConnection已弃用

我已升级到IOS9 xcode，但无法使用获取Web服务答案的方法，这部分是NSData * urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:＆response error:＆error];不推荐使用。

https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSURLConnection_Class/index.html#//apple_ref/doc/uid/TP40003755

NSString *post =[[NSString alloc] initWithFormat:@"lang=%@&type=ssss",@"en"];
NSURL *url=[NSURL URLWithString:@"http://www.xxxxxxxxxx.com/xxxxxxx/ws/get_xxxxx.php"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSLog(@"esta es la url: %@", postData);
NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSError *error = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

if ([response statusCode] >=200 && [response statusCode] <300)
{
    NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:urlData options:kNilOptions error:&error];
    NSInteger success = [(NSNumber *) [jsonData objectForKey:@"success"] integerValue];
    if(success == 1)
    {
        if (self.lugares != nil) {
            self.lugares = nil;
        }
        self.lugares = [[NSMutableArray alloc] initWithArray:[jsonData objectForKey:@"lugares"]];
    }
    else
    {
        NSLog(@"no hay datos :C");
    }
}
else
{
    NSLog(@"No encontrado");
}

最佳答案

您的实际问题不是NSURLConnection的使用，即使它也被描述，ios9也会处理它，这是您从ios9使用的http请求的问题苹果不鼓励将HTTP请求用作应用程序传输安全性(ATS)的一部分

来自Apple文档:



您可以通过将此 key 添加到项目的info.plist中来绕过此操作

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