关于iphone-应用报错incorrect decrement 的问题

创建NSString属性，并且合成属性，在viewDidLoad中对属性进行初始化。

问题：使用 [self.fName release]，静态分析其显示错误
`'Incorrect decrement of the reference count of an object that is not owned at this point by the caller'.
`
相关代码：

@interface ViewController : UIViewController
@property(nonatomic,retain)NSString *fName;
@end
@implementation ViewController
@synthesize fName;
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.fName =@"Hello";
    [self.fName release];//Analyzer showgin error here.
}
