But other times you may see a screen with a slider that says slide to answer with no option to decline.

但在其他時候，你可能會看到螢幕上有一個滑塊，上面寫著 "滑動接聽"，而沒有拒絕的選項。

So what's going on here?

這到底是怎麼回事？

Well, Apple actually provides two different incoming call screens depending on the state of the device.

實際上，蘋果會根據設備狀態提供兩種不同的來電界面。

If it's unlocked and being used, it'll show the red and green buttons.

如果已解鎖並正在使用，則會顯示紅色和綠色按鈕。

If it's locked, the slider appears instead.

如果已鎖定，則會顯示滑塊。

The reason Apple does this is to prevent users from accidentally answering or declining calls while their phone is in their pocket, bag or purse.

蘋果之所以這樣做，是為了防止用戶將手機放在口袋、包或錢包裡時意外接聽或拒絕來電。

The buttons are easier to press, so Apple only shows them if you're actively using the phone.

這些按鈕更容易按下，是以蘋果只在你積極使用手機時才會顯示它們。

While the slider is much harder to activate accidentally.

而滑塊則更難被意外激活。

But this wasn't always the case.

但情況並非總是如此。

The first five versions of iOS only had one incoming call screen with the red and green buttons.

iOS 的前五個版本只有一個帶有紅綠按鈕的來電螢幕。

But users complained that they would accidentally decline or answer when reaching for their iPhone to see who was calling.

但用戶抱怨說，當他們伸手去拿 iPhone 看誰打來電話時，會不小心拒絕或接聽。

So in iOS 6, Apple introduced the slide to answer feature when iPhone was locked.

是以，在 iOS 6 中，蘋果推出了在 iPhone 鎖定時滑動接聽電話的功能。

But it wasn't really a new concept though.

但這並不是什麼新概念。

Apple would use slide to unlock since the original iPhone to prevent users from accidentally unlocking their device and dialing numbers.

蘋果公司從最初的 iPhone 開始就使用滑動解鎖技術，以防止用戶意外解鎖設備並撥打號碼。

This was actually a common issue with mobile phones at the time, and it was called butt dialing.

這其實是當時手機的一個常見問題，被稱為 "屁股撥號"。

Almost anyone who had a cell phone experienced this.

幾乎所有擁有手機的人都經歷過這種情況。

In fact, when iPhone was introduced, many people assumed butt dialing would become more common since the screen was activated by touch.

事實上，當 iPhone 推出時，許多人都認為按鍵撥號會變得更加普遍，因為螢幕是通過觸摸激活的。

But because Apple used the slide to unlock feature, it became less of an issue.

但由於蘋果公司使用了滑動解鎖功能，這個問題就變得不那麼嚴重了。

In today, butt dialing hardly ever happens.

在今天，屁股撥號幾乎不會發生。

Which is why it was a no-brainer to use the same feature for the incoming call screen, making it almost impossible for users to accidentally answer or decline calls.

是以，在來電螢幕上使用同樣的功能就變得輕而易舉，用戶幾乎不可能意外接聽或拒絕來電。

In fact, Apple may have made it too difficult.

事實上，蘋果公司可能已經把它做得太難了。

Because many users don't even know how to decline a call when the slide to answer screen appears, since there's no visual cue.

因為很多用戶甚至不知道如何在出現滑動接聽螢幕時拒絕接受來電，因為沒有視覺提示。

But it can be done by double pressing the side button.

但雙按側邊按鈕就可以實現。

So that is why iPhone has two ways to answer calls.

是以，iPhone 有兩種接聽電話的方式。
