AFNetworking 不使用 cocoapods 在 xcode8 上构建

Question

我正在使用 cocoapods 1.1.1，并尝试使用 pod install:

安装此文件

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
target "Pictabite" do
    pod 'AFNetworking', '~> 3.1'
    pod 'SDWebImage', '~>3.8'
    pod 'LLSimpleCamera', '~> 5.0'
end

但是，在我添加 AFNetworking 后项目没有生成。我在 Xcode:

上收到此错误

clang-real: error: linker command failed with exit code 1 (use -v to see invocation)

有什么想法吗？

Answer 1

不指定 cocoapods 版本，使用 use_frameworks! 会产生：

Installing AFNetworking (3.0.4)
Installing LLSimpleCamera (4.2.0)
Installing SDWebImage (3.7.5)

• pod --version: 1.1.1
• xcodebuild -version：Xcode 8.2.1，构建版本 8C1002

您的 Podfile 可能如下所示：

platform :ios, '10.0'

target 'Pictabite' do
    use_frameworks!

    pod 'AFNetworking'
    pod 'SDWebImage'
    pod 'LLSimpleCamera'
end

Swift3 编译示例

import AFNetworking
...
let configuration = URLSessionConfiguration.default
let manager = AFURLSessionManager(sessionConfiguration: configuration)

Objective-C 编译示例

#import "AFNetworking.h"
...
NSURLSessionConfiguration *configuration =
   [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager =
   [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
