Question

我只是想将此数组保存到用户默认值，它会随机崩溃。有时它有效，有时它给我EXC_BAD_ACCESS。我没有正确地发布一些东西吗？

- (void)setTextValue:(NSString *)valueText indexToSet:(NSUInteger)index
{
    [self.pageData replaceObjectAtIndex:index withObject:valueText];
    [[NSUserDefaults standardUserDefaults] setObject:self.pageData forKey:@"mynotes"];
}

这是我确定导致错误的方法。这是Xcode已经创建的一种方法，我将自己的自定义代码添加到。

- (nbookDataViewController *)viewControllerAtIndex:(NSUInteger)index storyboard:(UIStoryboard *)storyboard
{   
    nbookDataViewController *dataViewController = [storyboard instantiateViewControllerWithIdentifier:@"nbookDataViewController"];
    if (self.pageData.count > 0 && index < self.pageData.count)
    {
        NSString *val = (NSString *)[self.pageData objectAtIndex:index];
        dataViewController.dataObject = val;
    }
    else
    {
        NSDate *date = [NSDate date];
        NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
        [dateFormat setDateFormat:@"MMMM d, YYYY"];
        NSString *dateString = [dateFormat stringFromDate:date];
        //[dateFormat release];
        [self.pageData addObject:dateString];
        dataViewController.dataObject = (NSString *)[self.pageData objectAtIndex:index];
    }
    dataViewController.myModel = (nbookModelController *)self;
    dataViewController.dIndex = index;
    //[self.mySaveData setObject:self.pageData forKey:@"mynotes"];
    return dataViewController;
}
