xcode – Keychain adhoc发行版

在临时分发应用程序时,我们遇到了一些令人困惑的钥匙串访问问题,并且在跟踪原因时遇到了问题.所有配置文件都与我们的应用程序的包名称匹配.我们使用TestFlight进行分发,虽然我不认为这是问题所在.

我们只是设法让它在没有安装应用程序的iOS 7设备上运行.没有一个iOS 8设备是临时工作的.我们在开始时得到的错误是25300(errSecItemNotFound),现在重置供应配置文件后,我们得到一个普通的0(两者都在保存加载时仍然没有数据可以检索).从Xcode部署dev构建时,一切都很完美.

我已经分离了我们使用的keychain包装器的代码：

import UIKit
import Security

let serviceIdentifier = "com.Test.KeychainTest"

let kSecClassValue = kSecClass as NSString
let kSecAttrAccountValue = kSecAttrAccount as NSString
let kSecValueDataValue = kSecValueData as NSString
let kSecClassGenericPasswordValue = kSecClassGenericPassword as NSString
let kSecAttrServiceValue = kSecAttrService as NSString
let kSecMatchLimitValue = kSecMatchLimit as NSString
let kSecReturnDataValue = kSecReturnData as NSString
let kSecMatchLimitOneValue = kSecMatchLimitOne as NSString

class KeychainManager {

class func setString(value: NSString,forKey: String) {
    self.save(serviceIdentifier,key: forKey,data: value)
}

class func stringForKey(key: String) -> NSString? {
    var token = self.load(serviceIdentifier,key: key)

    return token
}

class func removeItemForKey(key: String) {
    self.save(serviceIdentifier,key: key,data: "")
}



class func save(service: NSString,key: String,data: NSString) {
    var dataFromString: NSData = data.dataUsingEncoding(NSUTF8StringEncoding,allowLossyConversion: false)!
    // Instantiate a new default keychain query
    var keychainQuery: NSMutableDictionary = NSMutableDictionary(objects: [kSecClassGenericPasswordValue,service,key,dataFromString],forKeys: [kSecClassValue,kSecAttrServiceValue,kSecAttrAccountValue,kSecValueDataValue])

    // Delete any existing items
    SecItemDelete(keychainQuery as CFDictionaryRef)

    if data == "" { return }

    // Add the new keychain item
    var status: OSStatus = SecItemAdd(keychainQuery as CFDictionaryRef,nil)
    var alertView = UIAlertView();
    alertView.addButtonWithTitle("Ok");
    alertView.title = "Status";
    alertView.message = "Saving (status)";
    alertView.show();
}

class func load(service: NSString,key: String) -> NSString? {
    // Instantiate a new default keychain query
    // Tell the query to return a result
    // Limit our results to one item
    var keychainQuery: NSMutableDictionary = NSMutableDictionary(objects: [kSecClassGenericPasswordValue,kCFBooleanTrue,kSecMatchLimitOneValue],kSecReturnDataValue,kSecMatchLimitValue])

    var dataTypeRef :Unmanaged<AnyObject>?

    // Search for the keychain items
    let status: OSStatus = SecItemCopyMatching(keychainQuery,&dataTypeRef)
    var alertView = UIAlertView();
    alertView.addButtonWithTitle("Ok");
    alertView.title = "Status";
    alertView.message = "Loading (status)";
    alertView.show();

    let opaque = dataTypeRef?.toOpaque()

    var contentsOfKeychain: NSString?

    if let op = opaque? {
        let retrievedData = Unmanaged<NSData>.fromOpaque(op).takeUnretainedValue()

        // Convert the data retrieved from the keychain into a string
        contentsOfKeychain = NSString(data: retrievedData,encoding: NSUTF8StringEncoding)
    } else {
        return nil
    }

    return contentsOfKeychain
}


}
