bridgeToObjectiveC没有Swift Beta 5。

I'm writing an app that uses bridgeToObjectiveC() on a String object. Since Beta 5 this is no longer available.

我正在编写一个应用程序，它在一个字符串对象上使用bridgeToObjectiveC()。因为测试版5已经没有了。

I'm trying to do this:

我试着这样做:

self.myList.filter{($0 as MyClass).name.bridgeToObjectiveC().localizedCaseInsensitiveContainsString(searchText)}

Which gives me the error:

这给了我一个错误:

'String' does not have a member named 'bridgeToObjectiveC'

What is the equivalent code in Beta 5?

5的等效代码是什么?

2 个解决方案

#1

Use as to cast to NSString for the same effect:

用于转换为NSString，以获得同样的效果:

("string" as NSString).localizedCaseInsensitiveCompare("other string")

Or like this with optional chaining:

或者像这样有选择性的链接:

("string" as NSString?)?.localizedCaseInsensitiveCompare("other string")

#2

try

试一试

_bridgeToObjectiveC()

_bridgeToObjectiveC()

instead of

而不是

bridgeToObjectiveC()

bridgeToObjectiveC()

as follows:

如下:

self.myList.filter{($0 as MyClass).name._bridgeToObjectiveC().localizedCaseInsensitiveContainsString(searchText)}
