Question

我正在尝试在我的UIViewController中设置一个数组。笔尖有时会反复加载到我的应用程序中。我将此添加到我的initWithNibName以初始化数组

NSMutableArray *temp = [[NSMutableArray alloc] initWithObjects:@"one",@"two",@"three",@"four",@"five",nil];
    [self setScoreArray:temp];
    [temp release];

scoreArray是具有合成属性的MutableArray。当我在viewDidLoad中访问数组时，我得到[[self scoreArray] count]为0.此外，当我反复加载nib时，我得到一个错误的访问错误。有什么建议？我错过了一步。谢谢。我在我的类声明中合成了数组的属性：

    NSMutableArray *_scoreArray;

然后

@property (nonatomic, retain) NSMutableArray *scoreArray;

然后在我的实现中

@synthesize scoreArray =_scoreArray;

和我的dealloc

    [_scoreArray release], _scoreArray = nil;

我正在编辑这篇文章，以展示我是如何用我的RootViewController加载笔尖的

- (void) createNewSlide:(NSInteger)slideIndex {

NSDictionary *slideObj = (NSDictionary *)[[self slidesDataSource] objectAtIndex:slideIndex - 1];
NSString *currentTitle = [slideObj objectForKey:@"title"];
[[self slideTitle] setText:currentTitle];
NSString *currentContent = [slideObj objectForKey:@"contentString"];
NSString *currentContentType = [slideObj objectForKey:@"contentType"];

if ([self currentVC] != nil) {
        [[self currentVC] reset];
        [self setCurrentVC:nil];
}

if ([currentContentType isEqualToString:@"slide"]) 
{

    [[self containerViewController] loadImage:currentContent];

}
else if ([currentContentType isEqualToString:@"quiz"])
{
    NSInteger quizNum = [[slideObj objectForKey:@"quizNum"] integerValue];
    NSLog(@"%s%@%d",__FUNCTION__,@"quizNum ",quizNum);
    QuizViewController *quizView = [[QuizViewController alloc] initWithNibName:@"QuizViewController" bundle:nil];
    [self setCurrentVC:quizView];
     [quizView release];
    [[self containerViewController] replaceSlideWithViewController:[self currentVC]];
}
else if ([currentContentType isEqualToString:@"PIDView"])
{
    PIDViewController *PIDView = [[PIDViewController alloc] initWithNibName:@"PIDView" bundle:nil];
    [self setCurrentVC:PIDView];
    [PIDView release];
    [[self containerViewController] replaceSlideWithViewController:[self currentVC]];

}
else if ([currentContentType isEqualToString:@"LoginView"])
{
    LoginViewController *login = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil];
    [self setCurrentVC:login];
    [login release];
    [[self containerViewController] replaceSlideWithViewController:[self currentVC]];
}

else if ([currentContentType isEqualToString:@"VakView"])
{
    VakViewController *vakView = [[VakViewController alloc] initWithNibName:@"VakView" bundle:nil];
    [self setCurrentVC:vakView];
    [vakView release];
    [[self containerViewController] replaceSlideWithViewController:[self currentVC]];
}

else if ([currentContentType isEqualToString:@"PlanView"])
{
    PlanViewController *planView = [[PlanViewController alloc] initWithNibName:@"PlanView" bundle:nil];
    [self setCurrentVC:planView];
    [planView release];
    [[self containerViewController] replaceSlideWithViewController:[self currentVC]];

}

感谢您的见解。 PlanView是导致问题的原因。但它不是在加载时，而是在它之后加载其他东西的时候。我运行了分析仪，它报告没有内存泄漏。 BTW，currentVC是一个综合属性。

你的UIViewController是如何创建的？如果它是通过另一个笔尖创建的，则-initWithNibName:bundle:不会被调用。而是调用-initWithCoder:和-awakeFromNib。

在initWithNibName中初始化一个数组
