当我进行分析以找出潜在的内存泄漏时，我得到“调用者此时不拥有的对象的引用计数的错误递减”：

- (int)downloadUrlTofolder:(NSString *)url filename:(NSString *)name tryTime:(int)tryTime
{
    int result = 0;
     GetFtpService *ftpService = [[GetFtpService alloc] initwithUrlandOutPut:url output:name];

    //I have delete the code here, but problem is not solved.

    [ftpService release];  //the potential problem point to this line
    return result;
}

下面是“initwithUrlandOutPut”方法：

- (id)initwithUrlandOutPut:(NSString *)url output:(NSString *)o
{
    if(self = [super init]) {
        self.urlInput = url;
        self.outPath = o;
        self.success = [NSString stringWithString:@"success"];
        self.connected = nil;
    }

    return self;
}

和界面：

@interface GetFtpService : NSObject <NSStreamDelegate>

@property (nonatomic, retain) NSInputStream *networkStream;
@property (nonatomic, copy) NSString *urlInput;
@property (nonatomic, retain) NSInputStream *fileStream;
@property (nonatomic, copy) NSString *outPath;
@property int tryTime;
@property (nonatomic, copy) NSString *success;
@property (nonatomic, copy) NSString *connected;

- (id) initwithUrlandOutPut:(NSString *)url output:(NSString *)o;

我想知道为什么会这样？以及如何解决？

我怀疑这是因为“initwith ...”中的“w”没有大写。因此，分析器可能不会将该方法识别为 init 方法。
