iOS 调用私有函数安装app 卸载 app

1、环境

　　1、OS X EI Caption 10.11.1 & Xcode 7

　　2、Xcode安装Command Line Tools 

　　3、iPhone 安装AppSync

2、MobileInstallation.framework 私有API

　　

/*!
 *  @brief  Mobile Installation 的回调定义
 */

typedef void (*MobileInstallationCallback)(CFDictionaryRef information);

/*!
 *  @brief  Mobile Installation 安装App (8.0)
 *  @param  bundlePath          IPA文件路径
 *  @param  parameters          unknown
 *  @param  unknown1            unknown
 *  @param  unknown2            unknown
 */

extern int MobileInstallationInstallForLaunchServices(CFStringRef bundlePath, CFDictionaryRef parameters, void *unknown1, void *unknown2) NS_AVAILABLE_IOS(8_0);
/*!
 *  @brief  Mobile Installation 卸载App (8.0)
 *  @param  bundleIdentifier    App的Bundle ID
 *  @param  parameters          unknown
 *  @param  callback            Mobile Installation 的回调
 *  @param  unknown             unknown
 */

extern int MobileInstallationUninstallForLaunchServices(CFStringRef bundleIdentifier, CFDictionaryRef parameters, MobileInstallationCallback callback, void *unknown) NS_AVAILABLE_IOS(8_0);

　　以上是函数符号

3、关键代码

　　

    void *lib = dlopen([frameworkPath UTF8String], RTLD_LAZY);
    if (lib)
    {
        MobileInstallationInstall pMobileInstallationInstall = (MobileInstallationInstall)dlsym(lib, "MobileInstallationInstall");
        if (pMobileInstallationInstall)
        {
            NSString* temp = [NSTemporaryDirectory() stringByAppendingPathComponent:[@"Temp_" stringByAppendingString:ipaPath.lastPathComponent]];
            if (![[NSFileManager defaultManager] copyItemAtPath:ipaPath toPath:temp error:nil]) {
                [self showAlertMessage:@"检查要安装的IPA路径是否正确!" Title:@"复制IPA文件失败"];
                [SVProgressHUD dismiss];
                return NO;
            }
            int ret = pMobileInstallationInstall(temp, [NSDictionary dictionaryWithObject:@"User" forKey:@"ApplicationType"], 0, temp);
            [[NSFileManager defaultManager] removeItemAtPath:temp error:nil];
            if (ret == 0)   {
                [self showAlertMessage:@"请退出桌面确定是否有个HelloIPA的程序！" Title:@"安装成功"];
                [SVProgressHUD dismiss];
                return YES;
            }
            else {
                [self showAlertMessage:@"若为真机，确定该设备已经jailbreak！" Title:@"安装失败"];
                [SVProgressHUD dismiss];
                return NO;
            }
        }
    }
    else {
        [self showAlertMessage:@"检查MobileInstallation.framework路径是否正确！" Title:@"无法连接到MobileInstallation"];
        [SVProgressHUD dismiss];
        return NO;
    }
    return NO;

　　以上代码可以在App中使用

4、使用ldid签名

　　上面的函数如果没有经过签名，会返回－1

　　

<dict><key>application-identifier</key><string>com.q2q.testIPAInstall222</string><key>com.apple.private.mobileinstall.allowedSPI</key><array><string>Install</string><string>Browse</string><string>Uninstall</string><string>InstallForLaunchServices</string><string>UninstallForLaunchServices</string></array><key>com.apple.springboard.debugapplications</key><true/><key>get-task-allow</key><true/><key>task_for_pid-allow</key><true/></dict>

　　直接使用ldid签名可执行文件后，重新打包成ipa就可以了。

　　如果觉得复杂，也可以在Xcode中设置

使用普通的账号就可以了

https://github.com/kryhear/IPAInstaller/tree/master/testIPAInstall.xcodeproj 工程中的代码没有设置签名，导致调用是不成功的
