我创建了一个测试项目来测试 admob 并学习如何使用它，但是当我构建我的项目时，当我尝试将 admob 添加到我的项目(Xcode 4.3.3)中时，出现 11 个 apple mach-o 链接器错误

h文件可以，这里是M文件(代码取自admob知识库)

#import "chViewController.h"

#define MY_BANNER_UNIT_ID @"my id is written in here"

@interface chViewController ()

@end

@implementation chViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad {
    [super viewDidLoad];

    // Create a view of the standard size at the top of the screen.
    // Available AdSize constants are explained in GADAdSize.h.
    bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];

    // Specify the ad's "unit identifier." This is your AdMob Publisher ID.
    bannerView_.adUnitID = MY_BANNER_UNIT_ID;

    // Let the runtime know which UIViewController to restore after taking
    // the user wherever the ad goes and add it to the view hierarchy.
    bannerView_.rootViewController = self;
    [self.view addSubview:bannerView_];

    // Initiate a generic request to load it with an ad.
    [bannerView_ loadRequest:[GADRequest request]];
}


- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

我已将 lib.googleadmobAds 添加到我的文件夹并将二进制文件与库链接(当我删除它时，我收到相同的错误，但其中 4 个不是 11 个)

我阅读了很多关于它的 stackoveflow 帖子，你们中的一些人说我还需要广告 adsupport.framework 但我找不到它我在库列表的链接二进制文件中没有看到它。

网上的这些解决方案都不起作用，我被卡住了。

它有什么问题我没有收到关于我的 h 或 m 文件的任何错误那么为什么 mach-o 链接器错误有人可以帮助我吗？

最佳答案

您需要链接 AdMob 所需的框架。

转到您的目标设置，然后在构建阶段，然后在将二进制文件与库链接并添加以下框架(您可能需要其他框架，这些是基于我看到的错误):

MessageUI.framework
StoreKit.framework
SystemConfiguration.framework
