通过字符串设置Objective-C属性 [英] Set Objective-C property by string

问题描述

我想知道是否有一个简单的方法来设置（或检索）Objective-C属性通过NSString ...可以使用 NSSelectorFromString ，但是我想要一个更容易（和更少的hacky方式）做它...像

I'm wondering if there's an easy way to set (or retrieve) an Objective-C property by a NSString... It is possible to use NSSelectorFromString, but I'd like an easier (and less hacky way) to do it... Something like

[object setProperty:@"propertyValue" named:@"propertyName"];

相当于：

object.propertyName = @"propertyValue";

我真的不想混淆 @propertyName 命令的并将其转换为 @ setPropertyName：

I don't really want to mess around with the @"propertyName" and turn it into a @"setPropertyName:" for the NSSelectorFromString command... I may have no other choice, but if anyone knows a better way to do this, your help would be greatly appreciated!

推荐答案

如果有人知道更好的方法，使用键值编码。您的示例为 [object setValue：@propertyValueforKey：@propertyName] 。

Use Key-Value Coding. Your example would be [object setValue:@"propertyValue" forKey:@"propertyName"].
