我该如何解决？

这是我的代码

.h：

#import <UIKit/UIKit.h>
#import <iAd/iAd.h>;

@interface Vampire_Quiz_FinalViewController : UIViewController <ADBannerViewDelegate>

{

    ADBannerView *adView;

    BOOL bannerIsVisible;

}

@property (nonatomic,assign) BOOL bannerIsVisible;

-(IBAction)V;
-(IBAction)A;
-(IBAction)I;

@end

的.m：

#import "Vampire_Quiz_FinalViewController.h"
#import "Q1ViewController.h"
#import "Vork.h"
#import "About.h"
#import "Instructions.h"

@implementation Vampire_Quiz_FinalViewController
@synthesize bannerIsVisible;

- (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;

    }

}

Derek是对的，我们需要更多信息才能给你一个完整的答案。但是，这确实指向了一些地方。

在您的应用启动期间，这似乎是一次崩溃。可能这是您的主xib文件的问题，默认的xib将按照应用程序的info.plist中的指定加载。（确保正在加载正确的xib。）某些内容未正确连接，类/连接组合不存在，或者错误的类正在尝试初始化。检查并确保您的类在xib中正确并且连接已正确设置。

我的应用程序不断崩溃，我不知道如何解决它？
