Ios Travis CI错误，带有非null

我的

.travis.yml

文件：

language: objective-c

before_install:
   - rvm use system
   - sudo gem install cocoapods -v '0.39.0'  

script: 
    xctool -workspace ProjectName.xcworkspace -scheme ProjectName build -sdk iphonesimulator

osx_image: xcode7.2

language: objective-c

osx_image: xcode7.2

before_install:
   - rvm use system
   - sudo gem install cocoapods -v '0.39.0'  

script: 
    xctool -workspace ProjectName.xcworkspace -scheme ProjectName build -sdk iphonesimulator

在Travis CI构建项目时，我遇到了多个错误，如：

- (instancetype __nonnull)initWithConfiguration:(NSURLSessionConfiguration *__nullable)configuration NS_DESIGNATED_INITIALIZER;
                ^
- (instancetype __nonnull)initWithConfiguration:(NSURLSessionConfiguration *__nullable)configuration NS_DESIGNATED_INITIALIZER;
  ^

---

因此Travis Xcode正在抱怨与

\uu nonnull

相关的问题，为了解决这个问题，我强制Travis Xcode版本为7.2，文件

.Travis.yml

中有以下行：

language: objective-c

before_install:
   - rvm use system
   - sudo gem install cocoapods -v '0.39.0'  

script: 
    xctool -workspace ProjectName.xcworkspace -scheme ProjectName build -sdk iphonesimulator

osx_image: xcode7.2

language: objective-c

osx_image: xcode7.2

before_install:
   - rvm use system
   - sudo gem install cocoapods -v '0.39.0'  

script: 
    xctool -workspace ProjectName.xcworkspace -scheme ProjectName build -sdk iphonesimulator

因此，我的最后一个

.travis.yml

文件是：

   - sudo gem install cocoapods -v '0.39.0'  

script: 
    xctool -workspace ProjectName.xcworkspace -scheme ProjectName build -sdk iphonesimulator

正如我在另一篇文章中所说的，

sudogem安装cocoapods-v'0.39.0'

还强制Travis使用所需的cocoapods版本

为了解决这个问题，我在

.Travis.yml

文件中强制将Travis Xcode升级为7.2版：

language: objective-c

before_install:
   - rvm use system
   - sudo gem install cocoapods -v '0.39.0'  

script: 
    xctool -workspace ProjectName.xcworkspace -scheme ProjectName build -sdk iphonesimulator

osx_image: xcode7.2

language: objective-c

osx_image: xcode7.2

before_install:
   - rvm use system
   - sudo gem install cocoapods -v '0.39.0'  

script: 
    xctool -workspace ProjectName.xcworkspace -scheme ProjectName build -sdk iphonesimulator
