NSIndexPath：消息发送到释放实例

Question

您可以提供任何帮助，将不胜感激。

我有具有的tableView，的DetailView，flipView，和浏览更详细查看一个应用程序。它是通过转换，直至26日元素精细运动。应用程序崩溃时，我打的按钮，导航到翻转和moreDetailView。

<强>我给出的错误消息：。[NSIndexPath row] message sent to deallocated instance

我想我可能是在提醒indexPath过很多次，但为什么做一切工作顺利，直到25元，然后停止工作？怎么了NSIndexPath得到释放？我永远不会释放它。

如果你知道，请帮助。谢谢！

Xcode的说，问题是在这里：

@implementation produceView aka *detailView*

- (IBAction)showInfo {

        FlippedProduceView *fView = [[FlippedProduceView alloc]initWithIndexPath:index];
    fView.flipDelegate = self;


    fView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentModalViewController:fView animated:YES];
         [fView release]; 

}


 - (IBAction) buttonPushed:(id)sender

{

    picView *pictureView = [[picView alloc]initWithIndexPath:index];


    pictureView.picDelegate = self;
    pictureView.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;     

    [self presentModalViewController:pictureView animated:YES];
        [pictureView release];
}

-(id)initWithIndexPath:(NSIndexPath *)myIndexPath {   
if (self == [super init]) {
            path = myIndexPath;

    }
    return self;

}

@implementation picView aka *moreDetailView*

- (void)viewDidLoad {
    RipeGuideAppDelegate *AppDelegate = (RipeGuideAppDelegate *)[[UIApplication sharedApplication] delegate];
    self.picViewArray = AppDelegate.arrayProduceInfo;

    NSMutableDictionary *dictionary = [picViewArray objectAtIndex:path.row];
}

@implementation FlippedProduceView aka *flipView*


- (id)initWithIndexPath:(NSIndexPath *)myIndexPath {
    if (self == [super init]) {
        indexes = myIndexPath;
    }
    return self;
}

- (void)viewDidLoad {
    RipeGuideAppDelegate *AppDelegate = (RipeGuideAppDelegate *)[[UIApplication sharedApplication] delegate];
    self.flipViewArray = AppDelegate.arrayProduceInfo;

    NSMutableDictionary *dictionary = [flipViewArray objectAtIndex:indexes.row];
}

Answer 1

您应该使用性质（@property (retain) NSIndexPath *path;），而不是实例变量，所以后来当你self.path = myIndexPath那么它提出了保留计数，所以当IndexPath会被自动释放它不会被释放。
