我尝试使用Stig的JSON库发出HTTP请求并解析JSON . 我收到此错误'autorelease'不可用：当我使用此代码时，在自动引用计数模式下不可用
NSURLRequest *request2;
request2 = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://sandbox.CompanyName.com/api/%@/users/%@/user_badges?url=CompanyName.map2.com&amount=999999999999",[information stringForKey:@"apiKey"] , [information stringForKey:@"userID"]]]];
NSURLConnection *connection2;
connection2 = [[NSURLConnection alloc] initWithRequest:request2 delegate:self startImmediately:YES];
NSURLResponse *resp2;
NSData *cData2 = [NSURLConnection sendSynchronousRequest:request2 returningResponse:&resp2 error:nil];
NSString *cDataString2 = [[NSString alloc] initWithData:cData2 encoding:NSUTF8StringEncoding];
NSLog(@"getUsersBadges called");
NSError *error4;
SBJSON *json4 = [[SBJSON new] autorelease];
// NSArray *luckyNumbers = [json objectWithString:responseString error:&error];
NSDictionary *luckyNumbers4 = [json4 objectWithString:cDataString2 error:&error4];
[cDataString2 release];
UPDATE
对于任何感兴趣的人，这是正确的代码：NSURLRequest * request2; request2 = [NSURLRequest requestWithURL：[NSURL URLWithString：[NSString stringWithFormat：@“http://sandbox.CompanyName.com/api/%@/users/%@/user_badges?url=CompanyName.map2.com&amount=999999999999 ",[information stringForKey:@" apiKey "] , [information stringForKey:@" userID”]]] ;;
NSURLConnection *connection2;
connection2 = [[NSURLConnection alloc] initWithRequest:request2 delegate:self startImmediately:YES];
NSURLResponse *resp2;
NSData *cData2 = [NSURLConnection sendSynchronousRequest:request2 returningResponse:&resp2 error:nil];
NSString *cDataString2 = [[NSString alloc] initWithData:cData2 encoding:NSUTF8StringEncoding];
NSLog(@"getUsersBadges called");
NSError *error4;
SBJSON *json4 = [SBJSON new];
// NSArray *luckyNumbers = [json objectWithString:responseString error:&error];
NSDictionary *luckyNumbers4 = [json4 objectWithString:cDataString2 error:&error4];

更改
SBJSON *json4 = [[SBJSON new] autorelease];至
SBJSON *json4 = [SBJSON new];这将允许您保持自动引用计数不变 .
你摆脱这个错误的方法是进入你的项目构建设置 . 搜索自动引用计数 . 一旦找到它，将值设置为“NO”
