Question

我在使用removeObjectAtIndex时遇到异常我在这个论坛上搜索过，但是我找不到这个例外的正确解决方案。实际上，当我点击按钮时，我从服务器获取数据，我获得了成功，而且我还需要删除该行，但所选行不会被删除。

我的异常： - 由于未捕获的异常终止应用程序＆＃39; NSInternalInconsistencyException＆＃39;，原因：＆＃39; - [ NSCFArray removeObjectAtIndex：]：发送到不可变对象的变异方法＆＃39; ***第一次抛出调用堆栈：（ 0 CoreFoundation 0x000000010cfd1c65 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x000000010c46bbb7 objc_exception_throw + 45 2 CoreFoundation 0x000000010cfd1b9d + [NSException raise：format：] + 205 3 CoreFoundation 0x000000010cfca70e - [__ NSCFArray removeObjectAtIndex：] + 94 4 SkigitApplication 0x00000001097fab80 __20- [主页确认：] _ block_invoke + 272 5 SkigitApplication 0x00000001098c8628 __64- [AFHTTPRequestOperation setCompletionBlockWithSuccess：failure：] _ block_invoke46 + 40 6 libdispatch.dylib 0x000000011160f186 _dispatch_call_block_and_release + 12 7 libdispatch.dylib 0x000000011162e614 _dispatch_client_callout + 8 8 libdispatch.dylib 0x0000000111616a1c _dispatch_main_queue_callback_4CF + 1664 9 CoreFoundation 0x000000010cf391f9 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE + 9 10 CoreFoundation 0x000000010cefadcb __CFRunLoopRun + 2043 11 CoreFoundation 0x000000010cefa366 CFRunLoopRunSpecific + 470 12 GraphicsServices 0x000000010db6da3e GSEventRunModal + 161 13 UIKit 0x000000010acf7900 UIApplicationMain + 1282 14 SkigitApplication 0x00000001098c65bf main + 111 15 libdyld.dylib 0x0000000111663145 start + 1 16 ??? 0x0000000000000001 0x0 + 1 ） libc ++ abi.dylib：以NSException类型的未捕获异常终止

这是我的代码：request是我的数组

In .h
NSMutableArray *request;

In .m


-(void)Confirm:(id)sender

{
NSString *test = [NSString stringWithFormat:@"WebserviceUrl"];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];




[manager GET:test parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
 {

    NSLog(@"JSON: %@", responseObject);
    if([[responseObject valueForKey:@"Success"]integerValue])
    {

        request=[[responseObject valueForKey:@"info"]mutableCopy];
        NSLog(@"array=%@",request);
        frndcount=[[[request valueForKey:@"is_new"]objectAtIndex:0]mutableCopy];
        NSLog(@"frndcount=%@",frndcount);
        notification_id= [[[request valueForKey:@"notification_id"]objectAtIndex:0]mutableCopy];
        NSLog(@"notification_id=%@",notification_id);
        item_id= [[[request valueForKey:@"item_id"]objectAtIndex:0]mutableCopy];;
        NSLog(@"item_id=%@",item_id);
        frnd_count.text=[NSString stringWithFormat:@"%@",frndcount];

        if (deleteIndexPath==0) {
           [request removeObjectAtIndex:deleteIndexPath.row];
            [self.msg_table deleteRowsAtIndexPaths:[NSArray arrayWithObject:deleteIndexPath] withRowAnimation:UITableViewRowAnimationFade];


        }



    }
}
     failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
         NSLog(@"Error: %@", error);
     }];
}

您的request对象是NSArray对象，它是不可变的。您应该将其更改为NSMutableArray并解决您的问题。

<强>更新

我不知道你是如何初始化这个对象的，但如果你正在做这样的事情：

NSMutableArray *request = someData;

引用对象可能不可变，因此您应该解决此问题：

NSMutableArray *request = [someData mutableCopy];

现在，你有一个可变数据。
