swift 中 NSRegularExpressions 的 NSArray [英] NSArray of NSRegularExpressions in swift

问题描述

fork here 有一个自定义的链接函数，但实际代码中的实现是在目标 C.这是代码行和她它再次打印:

The fork here has a custom link function but the implementation in the actual code is in objective C.This is the code line and her it is printed again:

- (NSArray<NSRegularExpression*>*)getRegularExpressions
{
   return [NSArray arrayWithObject:[NSRegularExpression regularExpressionWithPattern:@"#([a-zA-Z0-9])+" options:0 error:NULL]];
}

我想知道如何在 swift 中重现这个，我已经放置了所有框架代码，我只需要知道如何做到这一点.

I was wondering how i could reproduce this in swift, I have already placed all of the framework code, I just need to know how to do this.

推荐答案

试试这个

func getRegularExpressions() -> [NSRegularExpression] {
    var arrayOfExpressions = [NSRegularExpression]()
    do
    {
        let expresion = try NSRegularExpression(pattern: "#([a-zA-Z0-9])+", options:.CaseInsensitive)
        arrayOfExpressions.append(expresion)
    }catch _
    {
        arrayOfExpressions.removeAll()
        return arrayOfExpressions
    }
    return arrayOfExpressions;
}
