从理论上讲,我们可以构建一个包含模拟器,iPhone和iPad的静态库.

但是,Apple没有关于此的文档,我可以找到,并且Xcode的默认模板未配置为执行此操作.

我正在寻找一种可以在Xcode中完成的简单,可移植,可重用的技术.

一些历史:

• 在2008年,我们曾经能够制作包含sim和设备的单个静态库.Apple禁用了那个.
• 在整个2009年,我们制作了一对静态库 - 一个用于sim,一个用于设备.Apple现在也禁用了它.

1. 这是一个好主意,它是一种很好的方法,但它不起作用:http://www.drobnik.com/touch/2010/04/universal-static-libraries/

   • 他的脚本中有一些错误意味着它只适用于他的机器 - 他应该使用BUILT_PRODUCTS_DIR和/或BUILD_DIR而不是"猜测"它们)
   • Apple的最新Xcode阻止你做他做的事情 - 由于Xcode处理目标的方式(记录)改变,它根本不起作用)

2. 另一个提问者询问如何在不使用xcode的情况下执行此操作,以及专注于arm6与arm7部分的响应 - 但忽略了i386部分:如何为armv6,armv7和i386编译静态库(fat)

   • 由于Apple的最新变化,模拟器部分与arm6/arm7的区别不再相同 - 这是一个不同的问题,见上文)

每次从CocoaPods导入文件时,我都会收到Apple Mach-O链接器错误.

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_FBSession", referenced from: someFile
ld: symbol(s) not found for architecture arm64

对于我使用的各种Pod,我得到了大约12个.

我正在尝试使用XCode 5为iPhone 5S构建.

我一直在尝试使用SO的各种解决方案,但还没有任何解决方案.

如何修复Apple Mach-O链接器错误？

刚发现另一个可能有趣的警告,我希望这能引导我找到解决方案:

Ignoring file ~/Library/Developer/Xcode/DerivedData/SomeApp/Build/Products/Debug-iphoneos/libPods.a, 

file was built for archive which is not the architecture being linked (arm64):~/Library/Developer/Xcode/DerivedData/someApp/Build/Products/Debug-iphoneos/libPods.a

一个Xcode初学者的问题:

这是我第一次使用Xcode 4.6.3.

我正在尝试编写一个非常简单的控制台程序,搜索配对的BT设备并将它们打印到NSLog.

它构建时出现以下错误:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_IOBluetoothDevice", referenced from:
      objc-class-ref in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我疯狂地搜索.常见问题应该是对文件的引用,其中只导入头文件,链接器不会找到实现(*.m-file).然而,IOBluetooth库是一个像Foundation Framework一样的标准框架.

我在上述陈述中缺少什么？

我也尝试过为32位机器构建它(再次构建失败).这显然是一个链接器错误,但我不知道它与它有什么关系,除了在x86和x64架构上找到IOBluetoothDevice的实现存在问题,而头文件来自标准包含的Framework,称为IOBluetooth？

为了您的信息,我的主要代码"main.m"是:

#import <Foundation/Foundation.h>
#import <IOBluetooth/objc/IOBluetoothDevice.h>          // Note the import for bluetooth
#import <IOBluetooth/objc/IOBluetoothDeviceInquiry.h>   // Note the import for bluetooth


int main(int argc, const char * argv[])
{
    @autoreleasepool {
        IOBluetoothDevice *currentDevice;
        NSArray *devices = [ IOBluetoothDevice pairedDevices];


        for (id …

尝试在现有应用程序中使用Layar SDK时出现以下错误.我怎么解决这个问题？

我想做什么

在我的iPhone项目中集成Zxing,QR码阅读器框架.我从这里检查了ZXing sdk .我运行了ZXing的示例项目,名为ScanTest,没有任何问题.但是当我尝试将库与我的项目集成时,我收到了提到的错误.

项目规范

• 目标操作系统:iOS 6.0
• 部署目标:iOS 5.0或更高版本.
• 测试:iPhone 4和iPhone 3GS.
• XCode:Xcode 4.5.1
• ZXing版:2.0

问题

当我构建时,在完成ZXing自述文件中的每个集成步骤后,我都会遇到构建错误

Undefined symbols for architecture armv7:
  "std::basic_ostream<char, std::char_traits<char> >& std::operator<<<std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)", referenced from:

      zxing::common::StringUtils::guessEncoding(unsigned char*, int, std::map<unsigned int, std::string, std::less<unsigned int>, std::allocator<std::pair<unsigned int const, std::string> …

在zxing iphone项目中,自述文件指出:

• 当尝试使用ZXingWidgetController构建自己的项目时,会发生链接器错误,例如"未定义引用".如果此错误看起来像c ++未定义的引用,那么将main.m重命名为main.mm(Objective-C++源后缀)可能会解决问题

确实如此.但我想知道为什么？

我偶然发现了一个我需要处理的项目问题.该项目使用Cocoapods来管理其库.我pod install像往常一样开始运行,但xcode给了我错误.我得到了Undefined symbols for architecture armv7你在下面的图片中看到的:

所有这些符号都是我用于项目的库.例如.AFNetworking,RNBlurModalView.我试图从项目中删除所有Cocoapods相关文件并pod install再次运行,但它仍然无法解决问题.

到目前为止我做了什么:

• 清理项目并重新构建.
• 删除Cocoapods相关文件并pod install再次运行.
• 试图在Project Target中的Compile Sources中添加类,但不能.该类位于Pods工作区中.
• 设置编译有源体系仅从YES到NO.

我也尝试了同样问题的解决方案,但没有一个对我有用.

如果它有帮助,我正在使用xCode6和Cocoapods 0.34.4.项目有效的架构是armv7 and armv7s.

更新:运行时pod install --verbose

我有一个奇怪的链接器问题.我的代码看起来像这样:

    double given_amount = self.modelController.levelCompleteRewardAmount;
    swrve_currency_given(swrve, (CFStringRef)@"currencyName", given_amount);

我在两个不同的地方有这个代码:在objective-c和objective-c ++文件中.它在objective-C land中编译很好,但是swrve_currency_given()函数在我的WGController.mm文件中导致以下内容:

Undefined symbols for architecture armv7:
  "swrve_currency_given(Swrve*, __CFString const*, double)", referenced from:
      -[WGController giveTheUserSomeCashForPlayingThisLevel] in WGController.o
ld: symbol(s) not found for architecture armv7
collect2: ld returned 1 exit status

我不完全确定这个错误是否与Obj-C与C++有关,但感觉就像它.我的理论是它可能认为它是Obj-C类的一个函数？'swrve'代码是第三方代码,一个.h和.c文件,我像这样导入:

#import "swrve.h"

任何帮助表示赞赏!谢谢

我已经创建了一个新的iOS项目,并根据官方说明添加了Google Analytics支持.

我添加到框架:

libGoogleAnalyticsServices.a
AdSupport.framework
CoreData.framework
SystemConfiguration.framework
libz.dylib

但它不适用于错误:
