是否可以同时为多个项找到rangeOfString

Question

我想为多个项找到rangeOfString，并尝试使用带有for-in循环的数组，但是这只是循环到数组的最后一个项并将其用于rangeOfString。是否可以使用带有rangeOfString的数组，以便它同时搜索所有术语，或者我是否必须为每个术语单独编写rangeOfString。

while true {
    let attempts = ["goodmorning","goodbye", "hello", "hi"]
    for attempt in attempts{

         tru = attempt




    let range = text.rangeOfString(tru, options: [], range: searchRange)

Answer 1

试试这个：

let attempts = ["goodmorning","goodbye", "hello", "hi"]
for attempt in attempts {
    if text.rangeOfString(attempt) != nil {
        print("found \(attempt)")
    }
}
