Answer 1

当我升级使用手动安装的旧版Google地图SDK的应用时,我注意到以下更改:

• 需要在Build Phases - > Link Bundle with Libraries中链接到CoreBluetooth.framework和Accelerate.framework.
• "Other Linker Flags"下的-all_load标志将导致"重复符号"错误.(改用-ObjC.)

如果您使用CocoaPods安装方法(根据他们当前的说明),它应该采用所需的框架,但它仍然会被-all_load搞砸.

确保包含以下内容

GoogleMaps SDK框架和捆绑包

GoogleMaps(扩展名为.framework)出现在您的根目录(.xcodeproj所在的位置)

您的xcode项目中引用了GoogleMaps(扩展名为.bundle)

以下框架

Accelerate.framework

AVFoundation.framework

CoreBluetooth.framework

CoreData.framework

CoreGraphics.framework

CoreLocation.framework

CoreText.framework

GLKit.framework

ImageIO.framework

的libc ++.dylib

libicucore.dylib

libz.dylib

OpenGLES.framework

QuartzCore.framework

Security.framework

SystemConfiguration.framework

构建设置

项目设置中的体系结构值包括armv7.

其他链接器标志有-ObjC,如果不存在则添加它

Answer 3

**_vImageBoxConvolve_Planar8, referenced from: (anonymous namespace)::CreateBlurredImage(CGImage*, double, double) in GoogleMaps(GLWaterGroup.o)**

This required "Accelerate.framework". So, please add it.

Steps:
1)Build Phases -> Link Bundle with Libraries.
2)Click "+",
3)Select "Accelerate.framework". Finish.

===================================

Others errors required "CoreBluetooth.framework. So, please add it also in similar way.

Answer 4

看起来 Google 的 API 需要 CoreBluetooth 来进行 Beacon 定位。CoreBluetooth.framework在构建阶段链接，一切都应该没问题。
