为什么我们选择Kotlin作为我们的目标语言之一。第2部分：Kotlin多平台

在kotlin插件为我们收集了许多用于不同架构的不同框架之后，我们手动创建了一个新的通用框架，我们可以从该通用框架中复制任何元数据（在本例中为arm64）：

//add meta files (headers, modules and plist) from arm64 platform
task copyMeta() {
    dependsOn build

    doLast {
        copy {
            from("$buildDir/bin/iphone/main/release/framework/${frameworkName}.framework")
            into "$buildDir/iphone_universal/${frameworkName}.framework"
        }
    }
}

, , , . lipo, :

//merge binary files into one
task lipo(type: Exec) {
    dependsOn copyMeta

    def frameworks = files(
            "$buildDir/bin/iphone32/main/release/framework/${frameworkName}.framework/$frameworkName",
            "$buildDir/bin/iphone/main/release/framework/${frameworkName}.framework/$frameworkName",
            "$buildDir/bin/iphoneSim/main/release/framework/${frameworkName}.framework/$frameworkName"
    )
    def output = file("$buildDir/iphone_universal/${frameworkName}.framework/$frameworkName")
    inputs.files frameworks
    outputs.file output
    executable = 'lipo'
    args = frameworks.files
    args += ['-create', '-output', output]
}

, - Kotlin MPP Info.plist UIRequiredDeviceCapabilities, ( ). PlistBuddy:

//workaround
//remove UIRequiredDeviceCapabilities key from plist file (because we copy this file from arm64, only arm64 architecture was available)
task editPlistFile(type: Exec) {
    dependsOn lipo

    executable = "/bin/sh"
    def script = './scripts/edit_plist_file.sh'
    def command = "Delete :UIRequiredDeviceCapabilities"
    def file = "$buildDir/iphone_universal/${frameworkName}.framework/Info.plist"

    args += [script, command, file]
}

edit_plist_file.sh:

/usr/libexec/PlistBuddy -c "$1" "$2"

, zip ( podspec ):

task zipIosFramework(type: Zip) {
    dependsOn editPlistFile
    from "$buildDir/iphone_universal/"
    include '**/*'
    archiveName = iosArtifactName
    destinationDir(file("$buildDir/iphone_universal_zipped/"))
}

podspec :

task generatePodspecFile(type: Exec) {
    dependsOn zipIosFramework

    executable = "/bin/sh"

    def script = './scripts/generate_podspec_file.sh'

    def templateStr = "version_name"
    def sourceFile = './podspec/template.podspec'
    def replaceStr = "$version"

    args += [script, templateStr, replaceStr, sourceFile, generatedPodspecFile]
}

generate_podscpec_file.sh :

sed -e s/"$1"/"$2"/g <"$3" >"$4"

curl :

task uploadIosFrameworkToNexus(type: Exec) {
    dependsOn generatePodspecFile

    executable = "/bin/sh"
    def body = "-s -k -v --user \'$userName:$password\' " +
            "--upload-file $buildDir/iphone_universal_zipped/$iosArtifactName $iosUrlRepoPath"
    args += ['-c', "curl $body"]
}

task uploadPodspecFileToNexus(type: Exec) {
    dependsOn uploadIosFrameworkToNexus

    executable = "/bin/sh"
    def body = "-s -k -v --user \'$userName:$password\' " +
            "--upload-file $generatedPodspecFile $iosUrlRepoPath"
    args += ['-c', "curl $body"]
}

:

task createAndUploadUniversalIosFramework() {
    dependsOn uploadPodspecFileToNexus
    doLast {
        println 'createAndUploadUniversalIosFramework complete'
    }
}

Profit!
