NSControl isEnabled仅在OS X v10.0到OS X v10.9中可用 [英] NSControl isEnabled only available in OS X v10.0 through OS X v10.9

问题描述

有人知道为什么NSControl的isEnabled已被移除而setEnabled：仍然工作？

Does anybody know why NSControl's isEnabled has been removed while setEnabled: is still working?

推荐答案

在OS X 10.10 iOS 8），Apple框架中的许多getter / setter方法对被 @property 声明替换。这两个使头部接口更清晰，并使那些API导入到Swift更多...好，Swifty。

In OS X 10.10 (and iOS 8), many of the getter/setter method pairs in Apple's frameworks were replaced by @property declarations. This both makes the header interface clearer and makes the import of those APIs into Swift more... well, Swifty.

// Before
- (BOOL)isEnabled;
- (void)setEnabled:(BOOL)enabled;

// After
@property(getter=isEnabled) BOOL enabled

文档没有完全更新以反映这一点，所以它错误地显示 isEnabled 已弃用，即使 @property 声明表示您仍然可以执行以下任何操作：

The documentation hasn't been fully updated to reflect that, so it erroneously shows isEnabled as deprecated, even though the @property declaration means you can still do any of the following:

BOOL foo = [control isEnabled];
[control setEnabled:YES];
BOOL bar = control.enabled;
control.enabled = YES;
