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.
