iOS GCM示例的无效Podfile

Question

我正在尝试安装GCM示例Xcode项目，遵循Google开发人员页面https://developers.google.com/cloud-messaging/ios/start上的说明。

但是，在第1步中，这个消息失败了：

[!] Invalid `Podfile` file: [!] The specification of `link_with` in the Podfile is now unsupported, please use target blocks instead..

全文如下：

$ pod try Google --no-repo-update

Performing CocoaPods Installation

[!] Invalid `Podfile` file: [!] The specification of `link_with` in the Podfile is now unsupported, please use target blocks instead..

 #  from /private/var/folders/d5/f4qpz1r530xbw5cyrbfk094h0000gp/T/CocoaPods/Try/Google/Samples/gcm/Podfile:10
 #  -------------------------------------------
 #  # and delete the link_with command.
 >  link_with 'GcmExample', 'GcmExampleSwift'
 #  ------------------------------------------

我尝试按照错误消息中的建议修改podfile，但是Podfile是重新生成的，即使在与--no-repo-update option一起运行时也会产生相同的错误。

我以前没有使用过Pods的经验，所以任何建议都很感激。

Answer 1

转到路径："/private/var/folders/lx/78jh00l90p95cs1cy_545t2r0000gn/T/CocoaPods/Try/Google/Samples/gcm“，然后打开pod文件并将其更新为

# GcmExample
 target 'GcmExample' do
  platform :ios, '7.0'
   pod 'Google/CloudMessaging'
end
# If using CocoaPods 1.0.0+, use the new target syntax.
#target 'GcmExample'
#target 'GcmExampleSwift'

# and delete the link_with command.
#link_with 'GcmExample', 'GcmExampleSwift'

然后，吊舱安装
