每当您在 iPhone 上打字时，您都会很快注意到键盘的自动更正(Auto-Correction)功能会以奇怪的方式搞砸事情。原因？它只是没有在其字典中包含所有俚语、名称或首字母缩略词，并且错误地引入了许多令人尴尬(introduces lots of embarrassing errors)的错误。
自动更正确实利用机器学习(take advantage of machine learning)来根据上下文对您的写作进行更改。随着时间的推移，它甚至会在键盘词典中添加新单词。但是，这还不足以防止它经常犯错误。
话虽如此，可以通过积极修复自动更正(Auto-Correction)问题来改善您在 iPhone 上的打字体验。您可以立即撤消不准确的更改（并加速机器学习），使用文本快捷方式来纠正重复出现的错误，或者在事情失控时重置键盘字典。
快速撤消自动更正的单词
当您的 iPhone 错误地“更正”您刚刚输入的单词时，您可以轻松撤消该操作，而无需重新输入。
自动更正(Auto-Correction)进行调整后立即点击删除(Delete )键，您应该会立即看到一个建议栏，其左侧有原始单词。选择它以使用它代替自动更正的单词。
一旦你多次撤销同一个单词，自动更正的机器学习算法应该会启动并将其保存到键盘的字典中。把它付诸实践，你很快就会得到一个大量的自定义词库，你可以在打字时自由使用。
您还可以在输入完所有内容（例如 iMessage）后恢复更改。只需(Just)双击自动更正的单词，然后从建议栏中选择原始单词。
停止自动更正
与其撤销自动更正(Auto-Correction)所做的更改，不如防止它在您输入单词时接管和修改它们。
iPhone 会先突出显示一个单词，然后再将其替换为其他内容。无需轻按空格(Space)并让自动更正(Auto-Correction)进行操作，只需从屏幕键盘的预测文本栏中选择您刚刚键入的同一个词 - 它应该显示在引号内。然后这个词应该没有任何变化地出现。
您以这种方式插入的任何单词最终都应保存到 iPhone 的键盘字典中。
使用(Use)（或仔细检查您的）文本替换
无论您撤消多少或在屏幕键盘中键入新单词，自动更正(Auto-Correction)并不总是保存新单词。更糟糕的是，它甚至可能最终“学习”你的错误并一遍又一遍地重复它们。这就是文本替换(Text Replacement)可以证明有用的地方。
文本替换(Text Replacement)是一项允许您使用快捷方式触发长短语的功能。例如，您可以键入首字母缩略词“HMU”(the acronym “HMU”)，并在其位置显示短语“ Hit me up”。
但您也可以利用文本替换(Text Replacement)来覆盖自动更正(Auto-Correction)无法添加到 iPhone 字典中的单词。例如，您可以将“Ryzen”设置为触发器和替换，您的 iPhone 将永远不会再将其更改为“Ruben”或“Ryder”。
转到设置(Settings )>常规(General )>键盘(Keyboard )>文本替换(Text Replacement)。然后，点击屏幕右上角的添加(Add)图标开始创建快捷方式。在短语(Phrase )和快捷方式字段中(Shortcut)填写(Fill)您不希望 iPhone 自动更正的单词，然后点击保存(Save)。
您可以根据需要创建任意数量的快捷方式。它们将通过 iCloud 同步到其他 iOS 和 iPadOS 设备，因此您不必到处添加快捷方式。
当自动更正开始出现异常时，您还应该检查您的文本替换条目。(Text Replacement)当您的 iPhone 处于解锁状态时，您永远不知道是否有人用一些有趣的快捷方式触发了您的恶作剧！
(Update)使用最新的系统软件(Latest System Software)更新iPhone
您可能偶尔会在 iPhone 上使用自动更正(Auto-Correction)功能遇到错误和故障。例如，您可能会发现该功能会无缘无故地替换完全正确的单词或大写它们。发生这种情况时，您必须立即应用待处理的 iOS 更新来修复自动更正问题。
例如，iOS 13 的 Auto-Correction 存在许多问题(iOS 13 had numerous problems with Auto-Correction)，随后的更新帮助修复了这些问题。但是类似的问题可能会再次出现，因此请转到“设置”(Settings ) > “常规(General )”并点击“软件更新”(Software Update )以安装适用于 iPhone 的最新更新。
在没有任何新更新可用的情况下，您应该尝试重新启动 iPhone。转到设置(Settings )>常规(General )>关机(Shut Down )并将电源(Power )图标拖动到屏幕右侧。然后，等待 30 秒，然后按住侧面(Side )按钮重新启动它。
重置 iPhone 的键盘字典(Keyboard Dictionary)
如果自动更正(Auto-Correction)通过反复进行不正确的更改继续导致问题，您应该重置 iPhone 的键盘字典。这应该会删除每个自定义单词，并为您提供从头开始“训练”自动更正(Auto-Correction)的全新状态。
转到设置(Settings )>常规(General )>重置(Reset )，然后选择重置键盘字典(Reset Keyboard Dictionary)将键盘字典重置为出厂默认设置。该过程不会删除您可能在 iPhone 上设置的任何文本替换条目。(Text Replacement)
在 iPhone 上禁用自动更正
如果自动更正(Auto-Correction)感觉太麻烦并且犯的错误多于纠正的错误，您可以完全关闭它。
为此，请转到Settings > General > Keyboard并关闭Auto-Correction旁边的开关。该页面还具有您可能想要禁用的其他与键盘相关的功能，例如Auto-Capitalization。
尽管关闭了自动更正，您仍然可以依靠文本替换(Text Replacement)来更正您所做的常见拼写错误（例如“teh”与“the”）。
修复自动更正
如果您刚开始使用 iPhone，自动更正(Auto-Correction)功能并没有您想象的那么糟糕。你输入的越多，它的工作就越好，上面的指针应该有助于消除折痕。但是，如果您正在考虑禁用该功能，那么在拔掉插头之前花一些时间使用它仍然是一个好主意。你只是可能会改变主意。
How to Fix Auto-Correct Issues on iPhone
Whenеver you tурe on an iPhone, уou’ll quickly notice the bizarre ways that the keyboard’s Auto-Correction functionality can mess things up. The reason? It just doesn’t have every slang, name, or acronym in its dictionary, and that introduces lots of embarrassing errors by mistake.
Auto-Correction does take advantage of machine learning to make changes to your writing based on context. It even adds new words to the keyboard dictionary over time. But, that’s simply not enough to prevent it from making frequent blunders.
Having said that, it is possible to improve your typing experience on the iPhone by actively fixing Auto-Correction issues. You can immediately undo inaccurate changes (and speed up machine learning), use text shortcuts to correct recurring errors, or reset the keyboard dictionary when things get out of hand.
Undo Auto-Corrected Words Quickly
When your iPhone ends up mistakenly “correcting” a word that you just typed, you can undo that easily without having to retype it.
Tap the Delete key as soon as Auto-Correction makes an adjustment, and you should immediately see a suggestions bar with the original word to the left of it. Select it to use that in place of the auto-corrected word.
Once you’ve undone the same word a couple of times, Auto-Correction’s machine learning algorithm should kick into gear and save it to your keyboard’s dictionary. Put that into practice, and you’ll soon end up with a substantial library of custom words you can freely use while typing.
You can also revert changes after you’ve finished typing in everything (like an iMessage, for example). Just double-tap an auto-corrected word and pick the original from the suggestions bar.
Stop Auto-Correction From Kicking In
Rather than undoing changes that Auto-Correction makes, you can prevent it from taking over and modifying words as you type them out.
The iPhone highlights a word before replacing it with something else. Instead of tapping Space and letting Auto-Correction make its move, simply select the same word you just typed from the onscreen keyboard’s predictive text bar—it should show up within quotes. The word should then appear without any changes.
Any words you insert that way should eventually save over to the iPhone’s keyboard dictionary.
Use (or Double-Check Your) Text Replacements
Auto-Correction doesn’t always save new words no matter how much you undo or type them into the onscreen keyboard. To make matters worse, it may even end up “learning” your mistakes and repeat them over and over again. That’s where Text Replacement can prove useful.
Text Replacement is a feature that allows you to trigger long phrases with the use of shortcuts. For example, you can type the acronym “HMU” and have the phrase “Hit me up” show in its place instead.
But you can also take advantage of Text Replacement to override Auto-Correction for words that it fails to add to your iPhone’s dictionary. For instance, you can set “Ryzen” both as the trigger and replacement, and your iPhone will never change that to “Ruben” or “Ryder” again.
Go to Settings > General > Keyboard > Text Replacement. Then, tap the Add icon at the top-right of the screen to start creating a shortcut. Fill in a word that you don’t want your iPhone to auto-correct into both the Phrase and Shortcut fields, and tap Save.
You can create as many shortcuts as you want. They’ll sync over iCloud to other iOS and iPadOS devices, so you don’t have to add your shortcuts everywhere.
You should also check your Text Replacement entries when Auto-Correction starts to behave strangely. You never know if someone’s pranked you with some funny shortcut triggers while your iPhone was lying around unlocked!
Update iPhone With Latest System Software
You may occasionally run into bugs and glitches with Auto-Correction on the iPhone. For instance, you may find the functionality replacing perfectly correct words or capitalizing them for no reason. When that happens, you must apply pending iOS updates immediately to fix auto-correct issues.
For instance, iOS 13 had numerous problems with Auto-Correction, and subsequent updates helped fix them. But similar issues can crop up again, so go to Settings > General and tap Software Update to install the latest updates for your iPhone.
In instances where there aren’t any new updates available, you should try restarting your iPhone. Go to Settings > General > Shut Down and drag the Power icon to the right of the screen. Then, wait for 30 seconds before holding down the Side button to boot it back up again.
Reset Your iPhone’s Keyboard Dictionary
If Auto-Correction continues to cause issues by repeatedly making incorrect changes, you should reset the iPhone’s keyboard dictionary. That should delete every custom word and provide you with a clean slate to start “training” Auto-Correction from scratch.
Head over to Settings > General > Reset and select Reset Keyboard Dictionary to reset the keyboard dictionary to factory defaults. The procedure will not remove any Text Replacement entries that you may have set up on your iPhone.
Disable Auto-Correction on iPhone
If Auto-Correction feels like too much of a hassle and makes more mistakes than it corrects, you can turn it off completely.
To do that, head over to Settings > General > Keyboard and turn off the switch next to Auto-Correction. The page also has other keyboard-related features that you may want to disable, such as Auto-Capitalization.
Despite turning off Auto-Correction, you can still rely on Text Replacement to correct common typos that you make (such as “teh” with “the”).
Fixing Auto-Correct
If you just started using an iPhone, Auto-Correction isn’t as bad as you may think. The more you type, the better it gets at its job, and the pointers above should help iron out the creases. If you’re thinking about disabling the functionality, however, it’s still a good idea to spend some time with it before pulling the plug. You just might change your mind.
