错误'autorelease'不可用：在自动引用计数模式下不可用

Question

我试图使用Stig的JSON库进行HTTP请求和解析JSON。我得到这个错误“自动释放”不可用：自动引用计数模式不可用时，我使用此代码

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] autorelease]; 
// NSArray *luckyNumbers = [json objectWithString:responseString error:&error]; 
NSDictionary *luckyNumbers4 = [json4 objectWithString:cDataString2 error:&error4]; 

[cDataString2 release];

UPDATE

任何有兴趣，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]; 

Answer 1

变化

SBJSON *json4 = [[SBJSON new] autorelease];

到

SBJSON *json4 = [SBJSON new];

这将允许你离开自动引用计数完好。

Answer 2

您摆脱此错误的方式是进入您的项目构建设置。搜索自动引用计数。一旦你找到它的值设置为 “否”
