iPhone OS上的NSDate dateByAddingTimeInterval？ [英] Whither NSDate dateByAddingTimeInterval on iPhone OS?

问题描述

问候！我一定要看东西看看这个摘录自 iPhone 操作系统参考库：

Greetings! I must be seeing things. Look at this excerpt from the iPhone OS reference library:

addTimeInterval：返回一个新的NSDate
对象，该对象设置为相对于接收方的给定数量
秒。
（已弃用，此方法已替换为 dateByAddingTimeInterval：。）

addTimeInterval: Returns a new NSDate object that is set to a given number of seconds relative to the receiver. (Deprecated. This method has been replaced by dateByAddingTimeInterval:.)

但是，它在文档和标题中都找不到。如果我查看Mac OS SDK，那么那么我找到了。

However, it is nowhere to be found in the docs, nor in the headers. If I look at the Mac OS SDK, then I find it.

Typo？只要继续使用 addTimeInterval：毕竟

Typo? Just keep using addTimeInterval: after all??

推荐答案

这实际上是文档中的错误。在Mac OS X 10.6中不推荐使用 addTimeInterval：，但不能在iPhone OS 3.1.2中使用。

It's actually an error in the docs. addTimeInterval: is deprecated in Mac OS X 10.6 but not in iPhone OS 3.1.2.

您可以在MacOS和iPhoneOS中查看NSDate.h，您会看到差异。

You can look at the NSDate.h in MacOS and in iPhoneOS and you'll see the difference.

iPhone OS中的NSDate.h

NSDate.h in iPhone OS

- (id)addTimeInterval:(NSTimeInterval)seconds;

和NSDate.h

- (id)addTimeInterval:(NSTimeInterval)seconds DEPRECATED_IN_MAC_OS_X_VERSION_10_6_AND_LATER;
- (id)dateByAddingTimeInterval:(NSTimeInterval)ti AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER;
