我想在即将推出的应用程序中使用Flurry广告.我已经安装了分析软件包,并且喜欢跟踪用户和事件是多么容易.

但是,我在使用新的4.0.1 SDK实现广告时出错,我找不到答案.每次我尝试构建我的Xcode 4.2项目时,都会收到以下错误消息:

Undefined symbols for architecture armv7:
  "_MPMoviePlayerLoadStateDidChangeNotification", referenced from:

  -[FlurryVideoPlayer moviePreloadDidFinish:] in libFlurryAds.a(FlurryVideoPlayer.o)
ld: symbol(s) not found for architecture armv7 …

这是我的代码:

-(void) captureOutput:(AVCaptureOutput*)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection*)connection
{
    CVImageBufferRef imageBuffer = CMSampleBufferGetImageBuffer( sampleBuffer );
    CGSize imageSize = CVImageBufferGetEncodedSize( imageBuffer );
    // also in the 'mediaSpecific' dict of the sampleBuffer

    NSLog( @"frame captured at %.fx%.f", imageSize.width, imageSize.height );
}

(这与问题无关,但这是一个功能AVCaptureVideoDataOutputSampleBufferDelegate)

无论如何,问题是CMSampleBufferGetImageBuffer CVImageBufferGetEncodedSize无法识别.我收到了错误:

Undefined symbols for architecture i386:
  "_CMSampleBufferGetImageBuffer", referenced from:

这是一个标准错误:架构armv7的未定义符号 但是解决方案对我不起作用: - 我正确地将框架添加到Link Binary With Libraries.- 我导入了<CoreMedia/CMSampleBuffer.h>,其中包含.h中的这些类.

那么问题是什么？

归档时(发布时)我收到错误

ld: entry point (_main) undefined. for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

ld: entry point (_main) undefined. for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

任何帮助将不胜感激.

我正在尝试在 Xcode 12.5 上构建 IOS 项目。连接真实设备或尝试使用模拟器构建时没有问题。但是当选择任何 IOS 设备时我收到此错误。选择任何 IOS 设备来存档我的项目，但我在存档时收到错误消息。我已经更改了“构建活动拱门”。“仅”和“排除架构”设置多次，但问题仍未解决。

请帮我解决这个问题..

所以我正在使用3dar SDK,构建一个实现sdk和生成的SM3Dar.h头的独立应用程序没有问题.但是现在我正在尝试使用相同的sdk作为更大项目的一部分,它似乎没有正常运行.看起来它知道头文件在那里但是没有与那个和库正确通信.我正试图在iPhone 5上运行它,我有最新的XCode.

但我收到这些错误

我将LinkedInIOS登录演示与我当前的应用程序集成在一起:https: //github.com/jeyben/IOSLinkedInAPI

还添加支持类"AFNetworking".

如下所述,它给了我一个错误:

  "_kUTTagClassMIMEType", referenced from:
      _AFContentTypeForPathExtension in AFURLRequestSerialization.o

ld: symbol(s) not found for architecture armv7

请建议我任何有关它的解决方案.我的部署目标是5.0.

我需要了解这意味着什么以及我将来如何解决它.

我一直在关注本指南,并严格遵循,

https://cms.paypal.com/cms_content/US/en_US/files/developer/PP_MPL_Developer_Guide_and_Reference_iPhone.pdf

我已经从PayPal SDK将以下文件添加到我的解决方案中

![PayPal SDK] [1]

..我的解决方案中的文件图像,不允许发布图像,我没有超过10分

我已将PayPal.h和PayPalAdvancedPayment.h导入我的一个类中,paypal提供的示例代码位于该指南的第30页.

我添加它确保没有明显的错误,然后构建解决方案.我的解决方案一直在构建和运行,直到我导入这两个文件.

PayPal.h和PayPalAdvancedPayment.h

![XCode构建错误] [2]

..是XCode中调试错误的图像
