错误：无法识别的选择器发送到实例 [英] Error: unrecognized selector sent to instance

问题描述

我有一个自定义对象 Spaces ：

#import "Spaces.h"


@implementation Spaces

@synthesize spaceName;
@synthesize spaceUsers;
@synthesize spaceIcon;
@synthesize spaceID;

@synthesize imageURLString;


- (void)dealloc
{
    [spaceName release];
    [spaceUsers release];
    [spaceIcon release];

    [imageURLString release];

    [super dealloc];
}

@end

我的根视图控制器 cellForRowAtIndexPath：并从 NSArray / p>

My root view controller implements a cellForRowAtIndexPath: and grabs from an NSArray of Spaces:

    [[cell spaceName] setText:aSpace.spaceName];
    [[cell spaceChatType] setText:@"People"];
    [[cell spaceActiveUsers] setText:aSpace.spaceUsers];

这个工作正常，我可以点击进入详细视图并返回列表，可能在表视图和详细视图之间来回5-6次点击，我在 [[cell spaceName] setText：aSpace.spaceName]; p>

This works fine and I can click to go into the detail view and back to the list, but after maybe 5-6 clicks back and forth between the table view and detail view, I get an error at [[cell spaceName] setText:aSpace.spaceName]; which is

' - [__ NSCFSet spaceName]：无法识别的选择器发送到实例0x6047b90

'-[__NSCFSet spaceName]: unrecognized selector sent to instance 0x6047b90'"

请帮助！任何洞察力将非常感激！

Please help! Any insight will be very appreciated!

更新：

我仍然得到相同的错误，但我把它缩小到这：

I'm still getting the same error but I've narrowed it down to the this:

- 我在didSelectRowAtIndexPath ...创建一个详细视图控制器...
- 详细视图正在push到viewcontroller并且显示正常，我有一个后退按钮添加
- 详细视图加载信息和刷新计时器
- 按后退按钮去回到表列表视图

-I'm creating a detail view controller on didSelectRowAtIndexPath... -The detail view is being pushed to the viewcontroller and displays fine, I have a back button added as well. -The detail view loads information and refreshes on a timer -Pressing the back button goes back to the table list view

这是我的细节视图不是从内存释放的问题，所以我越来越多的视图之间来回去更多的计时器关闭。我添加了一个检查viewWillDisappear，通过设置一个bool值停止计时器。

This is the problem my detail view is not being released from memory so the more I go back and forth between the views the more timers were going off simultaneously. I added a check to viewWillDisappear that stops the timer by setting a bool value.

我注意到细节视图不卸载...

I noticed that the detail view is not unloading...

从RootViewController：

From the RootViewController:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //no longer on initial view
    isinit = NO;

    //hide keyboard
    [spacesSearch resignFirstResponder];

    if (spaces != nil && spaces.count > 0)
    {
        //set back button reference
        UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Spaces" style:UIBarButtonItemStylePlain target:self action:@selector(returnSpacesList:)];  
        self.navigationItem.backBarButtonItem = backButton;

        [backButton release];

        DetailViewController *details = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; 

        //Grab Data from selected Space object and pass to DetailViewController
        Spaces *aSpace = nil;
        if (tableView == self.searchDisplayController.searchResultsTableView)
        {
            if ([self.filteredListContent count] == 0)
            {
                //self.lastSearchText
                NSLog(@"Create new space code!");
            }
            else
            {
                aSpace = [self.filteredListContent objectAtIndex:indexPath.row];
            }
        }
        else
        {
            aSpace = [spaces objectAtIndex:[indexPath row]];
        }

        //set title and display
        self.navigationController.title = [NSString stringWithFormat:@"/%@/",aSpace.spaceName];

        //pass data
        [details passedValue:aSpace.spaceID :aSpace.spaceName];

        [self.navigationController pushViewController:details animated:YES];

        [aSpace release];
        [details release];

    }
}

如何强制细节视图

谢谢

推荐答案

像 [cell spaceName] 已被autoReleased。我看不到你如何定义，但看看你的代码部分。

如果你需要更多的帮助，你需要提供更多的代码。

It sounds like [cell spaceName] has been autoReleased. I cannot see how you have defined that, but take a look at that part of your code.
If you need more help, you need to provide more code.
