PS 我是 iPhone 开发新手

谢谢

这是我的代码：

@implementation Vampire_Quiz_FinalViewController

- (IBAction)V;

{

    Vork *V = [[Vork alloc] initWithNibName:nil bundle:nil];

    [self presentModalViewController:V animated:NO];

}
- (IBAction)A;

{

    About *A = [[About alloc] initWithNibName:nil bundle:nil];

    [self presentModalViewController:A animated:NO];

}
- (IBAction)I;

{

    Instructions *I = [[Instructions alloc] initWithNibName:nil bundle:nil];

    [self presentModalViewController:I animated:NO];

}

- (void)dealloc {
    [super dealloc];
}

- (void)viewDidLoad {

    adView = [[ADBannerView alloc] initWithFrame:CGRectZero];

    adView.frame = CGRectOffset(adView.frame, 0, -50);

    adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifier320x50];

    adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifier320x50;

    [self.view addSubview:adView];

    adView.delegate=self;

    self.bannerIsVisible=NO;

    [super viewDidLoad];

}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner

{

    if (!self.bannerIsVisible)

    {

        [UIView beginAnimations:@"animateAdBannerOn" context:NULL];

        // banner is invisible now and moved out of the screen on 50 px

        banner.frame = CGRectOffset(banner.frame, 0, 50);

        [UIView commitAnimations];

        self.bannerIsVisible = YES;

    }

}



- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error

{

    if (self.bannerIsVisible)

    {

        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];

        // banner is visible and we move it out of the screen, due to connection issue

        banner.frame = CGRectOffset(banner.frame, 0, -50);

        [UIView commitAnimations];

        self.bannerIsVisible = NO;

    }

}



@end

我该如何解决？

您正在使用self.bannerIsVisible，但我既看不到合成器，也看不到 setter 和 getter。bannerIsVisible您是否在 .h 文件中 创建了一个属性？

要解决此崩溃，您应该在标题中定义属性并在您的实现中添加 @synthesize 语句。

也许你应该从更基础的东西开始，以了解基本的东西，比如属性、合成器、编译器警告（应该有）、调试等等。
我不想变得粗鲁，但是通过使用你不理解的复制代码你不会学到很多东西。

无法识别的选择器发送到实例：这意味着找不到该类的方法。检查类实现。
