“self.canDisplayBannerAds = YES;”使应用程序在iOS 8上崩溃？

Question

我想指出的是，自我是一个WelcomeViewController，它从UIViewController的继承：

WelcomeViewController.h

#import <UIKit/UIKit.h> 

@interface WelcomeViewController : UIViewController 
@property (strong, nonatomic) NSString* score; 
@property (strong, nonatomic) NSUserDefaults* preferences; 


@end 

WelcomeViewController.m

#import "WelcomeViewController.h" 
#import "GESceneController.h" 
#import <iAd/iAd.h> 
@interface WelcomeViewController() 
@property (weak, nonatomic) IBOutlet UILabel *scoreLabel; 
@property (weak, nonatomic) IBOutlet UILabel *highScoreLabel; 

@end 

@implementation WelcomeViewController 

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    self.canDisplayBannerAds = YES; 
    [self.scoreLabel setText:self.score]; 

    NSString* highScoreText = [NSString stringWithFormat:@"Meilleur score : %ld", 
           [self.preferences integerForKey:@"highscore"]]; 

    [self.highScoreLabel setText:highScoreText]; 

    // Do any additional setup after loading the view. 
} 

和我获取错误：[WelcomeViewController setCanDisplayBannerAds：]：无法识别的选择器发送到实例0x7d97 f080

您是否已将iAd文件导入链接的框架和库？如果没有，转到你的编译信息并一直滚动到底部，在那里你会找到'链接框架'，并将该框架添加到你的应用程序中。
