Swift 中的 NSLocalizedString 等价物是什么? [英] What's NSLocalizedString equivalent in Swift?

问题描述

是否有 NSLocalizedString(...) 的 Swift 等价物?在Objective-C中，我们通常使用:

Is there an Swift equivalent of NSLocalizedString(...)? In Objective-C, we usually use:

NSString *string = NSLocalizedString(@"key", @"comment");

如何在 Swift 中实现同样的效果?我找到了一个函数:

How can I achieve the same in Swift? I found a function:

func NSLocalizedString(
    key: String,
    tableName: String? = default,
    bundle: NSBundle = default,
    value: String = default,
    #comment: String) -> String

但是，它很长，一点也不方便.

However, it is very long and not convenient at all.

推荐答案

NSLocalizedString 也存在于 Swift 的世界中.

The NSLocalizedString exists also in the Swift's world.

func NSLocalizedString(
    key: String,
    tableName: String? = default,
    bundle: NSBundle = default,
    value: String = default,
    #comment: String) -> String

tableName、bundle 和 value 参数标有 default 关键字，这意味着我们可以在调用函数时省略这些参数.在这种情况下，将使用它们的默认值.

The tableName, bundle, and value parameters are marked with a default keyword which means we can omit these parameters while calling the function. In this case, their default values will be used.

由此得出结论，方法调用可以简化为:

This leads to a conclusion that the method call can be simplified to:

NSLocalizedString("key", comment: "comment")

Swift 5 - 没有变化，仍然如此.

Swift 5 - no change, still works like that.
