如何从 swift 中的递归函数转义(到初始调用位置)?

How to escape (to initial calling place) from a recursive function in swift?

var currentCount = 0
let totalCount = 100

func myEscapingRecursiveFunction(_ json: String, done: @escaping (Bool) -> Void) {
    
currentCount+=1

    if currentCount == totalCount {
        
        done(true)
    }
    else {
        myEscapingRecursiveFunction("xyz") { done in
        // what should I do here????
    } 
}

通话中

 // (Initially called here)
myEscapingRecursiveFunction("xyz") { done in 
    if done {
        print("completed") // I want to get response here after the recursion is finished
    }
}

我希望我的函数仅在当前计数等于总计数时转义,否则它应该递归,问题是我想在它所在的地方得到响应最初被称为,但它总是会在上次调用它的地方执行完成处理程序代码。这里:

您只需将相同的转义块传递给递归函数即可。

所以这样调用你的函数。

myEscapingRecursiveFunction("xyz", done: done)
