我尝试了几种方法来使用UIAlertController而不是UIAlertView.我尝试了几种方法,但我无法使警报行动起作用.这是我的代码在IOS 8和IOS 9中正常工作,但是出现了弃用的标志.我尝试了下面的优雅建议,但我无法在此背景下使其发挥作用.我需要提交我的应用程序,这是最后要解决的问题.感谢您的任何进一步建议.我是新手.

#pragma mark - BUTTONS ================================
- (IBAction)showModesAction:(id)sender {
NSLog(@"iapMade: %d", iapMade3);

// IAP MADE ! ===========================================
if (!iapMade3) {

    //start game here
    gamePlaysCount++;
    [[NSUserDefaults standardUserDefaults]setInteger:gamePlaysCount forKey:@"gamePlaysCount"];
    NSLog(@"playsCount: %ld", (long)gamePlaysCount);

    if (gamePlaysCount >= 4) {
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
                                                     message: THREE_PLAYS_LIMIT_MESSAGE
                                                    delegate:self
                                           cancelButtonTitle:@"Yes, please"
                                           otherButtonTitles:@"No, thanks", nil];
       [alert show];

        NSString *path = [[NSBundle mainBundle] pathForResource:@"cow" ofType:@"wav"];
        _pop =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
        [_pop play];
        [self dismissViewControllerAnimated:true completion:nil];

    } else {
        if (gamePlaysCount == 1)  {
            // Create …

当我尝试在运行一个应用程序的iOS模拟器10使用xcode8我得到这些警报频繁.它们一次随机出现两个,并且不明显是什么触发它们.

下面是我得到的错误图片.

我试过以下事情.

• 清理并重建应用程序
• 重启xcode和模拟器
• 清除派生数据和重建应用程序.

我有一个文本框,我只对第一个字母大写有兴趣,那么如何在iPhone UITextField中做到这一点.

更新到之后Xcode 7.3,我的项目中会显示大量警告.

'++'已被弃用:它将在Swift 3中删除

有什么想法修复这个警告吗？是什么原因++以及--将来会被弃用？

我无法将所有的Objective C代码示例可用于添加数据和查询从数据iOS Keychain到斯威夫特.我正在尝试对字符串(访问令牌)进行基本存储并将其读回.我已经看过Stack Overflow上的其他一些问题,但我无法让它工作.我试图拼凑各种来源的解决方案.

编辑1:我尝试了一个更基本的设置,因为我认为我的self.defaultKeychainQuery可能搞砸了.我已将下面的代码更新为最新版本.

编辑2:搞定了.我没有正确地将数据值添加到保存查询中.我需要将字符串转换为NSData.我已将下面的代码更新为最新的工作版本.

编辑3:正如Xerxes在下面指出的那样,由于Dictionaries存在一些问题,此代码不适用于高于Beta 1的Xcode版本.如果你知道对此的修复,请告诉我.

更新:我把它变成了一个用Swift编写的一个名为Locksmith的钥匙串库.

保存

class func save(service: NSString, data: NSString) {
  var dataFromString: NSData = data.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
  // Instantiate a new default keychain query
  var keychainQuery: NSMutableDictionary = NSMutableDictionary(objects: [kSecClassGenericPassword, service, userAccount, dataFromString], forKeys: [kSecClass, kSecAttrService, kSecAttrAccount, kSecValueData])

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

  // Add the new keychain item
  var status: OSStatus = SecItemAdd(keychainQuery as …

UAlertView在iOS 9及更高版本中已弃用.什么是另类？

UIAlertView *new = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Your InApp Purchases were successfully restored" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[new show];

我试图在swift中分享图像和文本.但是当我选择通过facebook,messenger或whatsapp进行分享时,它只提供文本(图像不共享).我正在使用UIActivityViewController进行共享.

这是我的代码:

func displayShareSheet(latitude:NSString?, longitude:NSString?, image:UIImage?, address:NSString? ) {
    let activityViewController = UIActivityViewController(activityItems: [(latitude as NSString?)!, (longitude as NSString?)!, (image as UIImage?)!, (address as NSString?)!], applicationActivities: nil)
    presentViewController(activityViewController, animated: true, completion: {}
)
}

我有UIScrollView一个UIView内部.我想锁定x轴,以便视图只垂直滚动.如何启用方向锁定？

我试图传递访问令牌,Alamofire但在网络上的各种方法混淆.

以下是我们需要使用的方法.

let todosEndpoint: String = "https:url......."

let headers = [
            "Authorization": "Bearer \(token!)",
            "Content-Type": "application/X-Access-Token"
        ]
        let Auth_header    = [ "Authorization" : tokenString! ]

        Alamofire.request(todosEndpoint, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: Auth_header)
            .responseJSON { response in
                print("response.request \(response.request)")  // original URL request
                print("response.response \(response.response)") // HTTP URL response
                print("response.data \(response.data)")     // server data
                print("response.result \(response.result)")

                print("response \(response)")

        }

    }

要么

let aManager = SessionManager()
        aManager.session.configuration.httpAdditionalHeaders = [
            "Authorization": "Bearer tokenString"]

要么

let headerss = [
            "Authorization": …

我试图避免每次会话在Spotify for SDK中过期时用户的弹出窗口授予权限.

Pop出现一小时后,弹出窗口似乎再次授予用户权限,这样他就可以在我的应用程序上播放Spotify中的曲目,我在尝试续订会话时遇到错误:

[PLAYER][PLAY][SPOTIFY] Error renew Session Optional(Error Domain=com.spotify.auth Code=0 "Missing token refresh service." UserInfo={NSLocalizedDescription=Missing token refresh service.})
[PLAYER][SPOTIFY] Session could not be renewed,popup login

在这里我如何尝试更新会话:

//Renew Session
func renewSession(completion:@escaping (Bool)->())
{
    print("[PLAYER][PLAY][SPOTIFY] Renew Session requested ")

    let auth = SPTAuth.defaultInstance()
        auth?.renewSession(auth?.session, callback: { (error, session) in

            if (error != nil)
            {
                print("[PLAYER][PLAY][SPOTIFY] Error renew Session \(String(describing: error))")
                completion(false)
                return
            }

            auth?.session = session

            if auth?.session.isValid() == true
            {
                print("[PLAYER][PLAY][SPOTIFY] Renew Session Success")
                completion(true)
            }else
            {
                print("[PLAYER][PLAY][SPOTIFY] Renew Session …
