Apple’s iPhones and iPads use its own Lightning connector for charging and data transmission. You can purchase third-party cables and accessories, but they must be certified. If a cable or accessory wasn’t certified by Apple, you’ll see a warning message when you connect it. However, this message can sometimes appear incorrectly, too.
苹果的iPhone和iPad使用其自己的Lightning连接器进行充电和数据传输。 您可以购买第三方电缆和附件，但必须经过认证。 如果电缆或配件未经Apple认证，则在连接时会看到警告消息。 但是，此消息有时也可能显示不正确。
(How Apple’s Certification Works)
Apple offers an “MFi Certification Program.” “MFi” stands for “Made for iPhone,” “Made for iPad,” and “Made for iPod.” Third-party accessories and cables that advertise they’re “MFi certified” have gone through Apple’s certification process to ensure they’re compatible with Apple’s hardware and well-made.
苹果提供了“ MFi认证计划” 。 “ MFi”代表“ Made for iPhone”，“ Made for iPad”和“ Made for iPod”。 宣传通过“ MFi认证”的第三方配件和电缆已经过Apple的认证过程，以确保它们与Apple的硬件兼容且制作精良。
iPhones and iPads started enforcing this restriction when iOS 7 was introduced. There’s actually a little authentication chip inside Lightning cables and other accessories. This authentication chip communicates with your iPhone or iPad, which is how your device knows whether you’re using an Apple-approved cable or accessory, or one the manufacturer didn’t put through Apple’s certification program.
引入iOS 7后，iPhone和iPad开始强制执行此限制。 实际上，Lightning电缆和其他附件中有一个身份验证芯片。 该验证芯片与您的iPhone或iPad通信，这可以使您的设备知道您使用的是Apple认可的电缆或配件，还是制造商未通过Apple认证计划的电缆。
Cables that aren’t MFi certified don’t have the chip inside them, and they won’t work properly with an iPhone or iPad. When buying Lightning cables, be sure to get MFi-certified ones. That doesn’t mean you have to buy Apple’s cables, as there are less expensive options. For example, Amazon has its own AmazonBasics brand of Lightning cable that can be had for $7 each, while Anker’s MFi-certified cables can be had for $6 on Amazon. Apple charges $19 for its own cables. We’ve also had good luck with the longer Sundix-brand cables.
未通过MFi认证的电缆内部没有芯片，因此无法在iPhone或iPad上正常使用。 购买Lightning电缆时，请确保获得MFi认证的电缆。 这并不意味着您必须购买Apple的电缆，因为价格较便宜。 例如，亚马逊拥有自己的AmazonBasics品牌的Lightning电缆 ，每条售价7美元，而Anker经MFi认证的电缆在亚马逊上的售价为6美元。 苹果自己的电缆收费19美元。 对于更长的Sundix品牌电缆，我们也祝好运。
Apple has a web page designed to help you identify counterfeit or uncertified Lightning cables and accessories. It lays out Apple’s argument for why the certification process exists. Uncertified cables could damage your iPhone or iPad, or the cable itself might easily fall apart. The Lightning connector might fall off, get very hot, or not fit your device properly. You might be unable to sync or charge your iPhone or iPad with the cable, too. That’s why the message warns “This cable or accessory is not certified and may not work reliably with this iPhone (or iPad)”.
Apple有一个旨在帮助您识别假冒或未经认证的Lightning电缆和配件的网页。 它提出了苹果公司为何存在认证程序的论点。 未经认证的电缆可能会损坏您的iPhone或iPad，或者电缆本身很容易散开。 Lightning连接器可能会脱落，变热或无法正确安装设备。 您可能也无法使用电缆同步iPhone或iPad或为其充电。 这就是为什么该消息警告“此电缆或附件未经认证，并且可能无法与此iPhone(或iPad)正常工作”的原因。
(The Message Could Be an Error)
This message can sometimes appear in error, however. We’ve seen this particular error message a couple times using a charging cable we’d been using for an entire year. To fix it, we just unplugged the cable for a moment before plugging it back in. It’s worked fine with no warnings ever since. This was clearly a one-time bug, and the message shouldn’t have appeared. Other members of our staff have seen the issue once or twice as well.
但是，此消息有时可能会出现错误。 我们已经使用了整整一年的充电电缆，看到了几次特殊的错误消息。 要修复它，我们只需要先拔掉电缆一会儿再插回去。它运行良好，此后没有任何警告。 显然，这是一次错误，该消息不应该出现。 我们工作人员的其他成员也曾一两次看到此问题。
If you’re suddenly seeing this error message on your iPhone or iPad, and you’re using a cable or accessory that’s never prompted this message before, you might also be experiencing such a bug. Just unplug the cable from the iPhone or iPad and then plug it back in. If you’re charging your iPhone or iPad by plugging it into a PC or Mac, try plugging the cable into another USB port if that doesn’t work. If the message doesn’t appear again, everything is working properly and you don’t need to worry about it.
如果您突然在iPhone或iPad上看到此错误消息，并且使用的电缆或附件以前从未提示过此消息，则可能还遇到了此类错误。 只需从iPhone或iPad上拔下电缆，然后再将其重新插入即可。如果要通过将iPhone或iPad插入PC或Mac给iPhone或iPad充电，请尝试将电缆插入另一个USB端口，如果这不起作用。 如果该消息没有再次出现，则说明一切正常，您无需担心。
(Your Cable or Accessory Could Be Damaged)
If the message continues to appear with a certified cable every time you plug it in–or appears regularly, if not every time–it’s possible the cable is damaged. Less expensive, poorer quality cables are more vulnerable to this, even if they are certified. The cable could have frayed or been damaged by water, and you might see evidence of this if you just look at the cable. Of course, it’s possible the cable is damaged inside and there’s no way to tell from the outside. You may just need to purchase a new Lightning cable.
如果每次插入时该消息仍然通过认证电缆出现，或者如果不是每次都定期出现，则表明电缆已损坏。 即使价格低廉，质量较差的电缆也更容易受到影响，即使它们已通过认证。 电缆可能已磨损或被水损坏，如果仅查看电缆，则可能会看到证据。 当然，内部电缆可能已损坏，并且无法从外部分辨出来。 您可能只需要购买新的Lightning电缆。
There’s also the possibility that the charging ports may be partially obstructed. Examine the charging port on the iPhone or iPad and the connection where the cable meets the charging brick. Ensure the ports aren’t blocked with pocket lint, dust, or any other debris.
充电端口也有可能被部分阻塞。 检查iPhone或iPad上的充电端口以及电缆与充电砖的连接处。 确保端口没有被棉绒，灰尘或任何其他杂物阻塞。
As usual with an iPhone or iPad, the only way to disable this warning message and use the uncertified cable or accessory properly is by jailbreaking your iPhone or iPad and installing a tweak that allows them to function. However, it’s really not worth it–even if you’re already jailbreaking, you’re better off spending a bit extra to get higher-quality cables and accessories. This time, Apple’s overbearing control is actually a good thing.
与iPhone或iPad一样，禁用此警告消息并正确使用未经认证的电缆或附件的唯一方法是， 将iPhone或iPad越狱并进行调整以使其正常工作。 但是，这确实不值得-即使您已经越狱，也最好花一些钱来获得更高质量的电缆和配件。 这次，苹果霸道的控制实际上是一件好事。
If you did purchase an MFi-certified cable or accessory and regularly see this message, there’s a good chance that cable or accessory is broken. Try to get it replaced if it’s under warranty–if it’s no longer under warranty, if may have broken and you may just need to buy a new one.
如果您确实购买了MFi认证的电缆或附件并定期看到此消息，则很有可能电缆或附件已损坏。 如果它在保修期内，请尝试将其更换-如果不再保修，则可能已损坏，您可能只需要购买新的即可。
