I would like to get the device IDFA. How to get this info from iOS official API ?

我想买这个设备IDFA。如何从iOS官方API获取这个信息?

8 个解决方案

#1

First of all:

首先:

#import <AdSupport/ASIdentifierManager.h> 

If you would like to get it as an NSString, use:

如果你想把它作为NSString，使用:

[[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString]

So your code might look like this:

所以你的代码可能是这样的:

NSString *idfaString = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];

#2

You first have to check if user user has decided to opt out from ad tracking. Only if he allowed it you can use the IDFA.

您首先要检查用户是否决定退出ad跟踪。只要他允许，你就可以使用IDFA。

You can check it by calling isAdvertisingTrackingEnabled method of ASIdentifierManager.

您可以通过调用ASIdentifierManager的isAdvertisingTrackingEnabled方法来查看它。

isAdvertisingTrackingEnabled

isAdvertisingTrackingEnabled

Check the value of this property before performing any advertising tracking. If the value is NO, use the advertising identifier only for the following purposes: frequency capping, conversion events, estimating the number of unique users, security and fraud detection, and debugging.

在执行任何广告跟踪之前，检查该属性的价值。如果值为NO，则仅将广告标识符用于以下目的:频率上限、转换事件、估计唯一用户的数量、安全性和欺诈检测以及调试。

The following code snippet shows how to obtain a string value of IDFA.

下面的代码片段展示了如何获取IDFA的字符串值。

ObjC

@import AdSupport;

- (NSString *)identifierForAdvertising {
    // Check whether advertising tracking is enabled
    if([[ASIdentifierManager sharedManager] isAdvertisingTrackingEnabled]) {
        NSUUID *identifier = [[ASIdentifierManager sharedManager] advertisingIdentifier];
        return [identifier UUIDString];
    }

    // Get and return IDFA
    return nil;
}

Swift

import AdSupport

func identifierForAdvertising() -> String? {
    // Check whether advertising tracking is enabled
    guard ASIdentifierManager.shared().isAdvertisingTrackingEnabled else {
        return nil
    }

    // Get and return IDFA
    return ASIdentifierManager.shared().advertisingIdentifier.uuidString
}

#3

ASIdentifierManager is the official way to garner the Advertising Identification Number from a device running iOS 6+. You can use -[[ASIdentifierManager sharedManager] advertisingIdentifier]; to get it.

ASIdentifierManager是通过运行iOS 6+的设备获取广告识别号码的官方方式。您可以使用-[ASIdentifierManager sharedManager]广告标识符];去得到它。

#4

Get IDFA in Swift:

在迅速得到IDFA:

    import AdSupport

    ...

    let myIDFA: String?
    // Check if Advertising Tracking is Enabled
    if ASIdentifierManager.sharedManager().advertisingTrackingEnabled {
        // Set the IDFA
        myIDFA = ASIdentifierManager.sharedManager().advertisingIdentifier.UUIDString
    } else {
        myIDFA = nil
    }

#5

Beginning in iOS 10, when a user enables “Limit Ad Tracking,” the OS will send along the advertising identifier with a new value of “00000000-0000-0000-0000-000000000000.”

从iOS 10开始，当用户启用“限制广告追踪”时，操作系统会将广告标识符的新值“00000000-0000- 000000000000”发送出去。

Here's a commented helper class in Swift that will give you a nil object for the identifier if the user has turned advertisement tracking off:

在Swift中有一个注释帮助类，如果用户关闭了广告跟踪，它将为标识符提供一个nil对象:

import AdSupport

class IDFA {
    // MARK: - Stored Type Properties
    static let shared = IDFA()

    // MARK: - Computed Instance Properties
    /// Returns `true` if the user has turned off advertisement tracking, else `false`.
    var limited: Bool {
        return !ASIdentifierManager.shared().isAdvertisingTrackingEnabled
    }

    /// Returns the identifier if the user has turned advertisement tracking on, else `nil`.
    var identifier: String? {
        guard !limited else { return nil }
        return ASIdentifierManager.shared().advertisingIdentifier.uuidString
    }
}

Just add it to your project (for example in a file named IDFA.swift) and link the AdSupport.framework in your target via the "Linked Frameworks and Libraries" section in the General settings tab.

只需将其添加到您的项目中(例如，在名为IDFA.swift的文件中)，并通过General settings选项卡中的“链接框架和库”部分链接到目标中的AdSupport.framework。

Then you can use it like this:

然后你可以这样使用它:

if let identifier = IDFA.shared.identifier {
    // use the identifier
} else {
    // put any fallback logic in here
}

斯威夫特3 & 4

var IDFA = String()
if ASIdentifierManager.shared().isAdvertisingTrackingEnabled {
            IDFA = ASIdentifierManager.shared().advertisingIdentifier
}

Just to extend Amro's Swift answer, here's similar code wrapped in a method:

为了扩展Amro银行的快速回答，这里有一种方法中包含的类似代码:

import AdSupport

...

func provideIdentifierForAdvertisingIfAvailable() -> String? {
    if ASIdentifierManager.sharedManager().advertisingTrackingEnabled {
      return ASIdentifierManager.sharedManager().advertisingIdentifier?.UUIDString ?? nil
    } else {
      return nil
    }
  }
