ios 如何从应用商店 url 中提取 ID 号部分？

Question

我想从应用商店网址中提取 ID 号部分，例如，以下是两个应用商店网址: https://itunes.apple.com/app/apple-store/id882456583?pt=63826800&ct=%E5%AE%A3%E4%BC%A0%E8%B4%B4001&mt=8

https://itunes.apple.com/app/juan-pi-zhe-kou-shou-ji-shang/id639388447?mt=8&uo=4

我想提取“id”后面的数字，即 882456583 和 639388447。任何人都知道如何做到这一点？谢谢。

Answer 1

试试这个

swift :

let appStoreUrl = NSURL(string: "https://itunes.apple.com/app/juan-pi-zhe-kou-shou-ji-shang/id639388447?mt=8&uo=")
let appId = appStoreUrl?.lastPathComponent?.stringByReplacingOccurrencesOfString("id", withString: "")

objective-c :

NSURL *appStoreUrl = [NSURL URLWithString:@"https://itunes.apple.com/app/juan-pi-zhe-kou-shou-ji-shang/id639388447?mt=8&uo="];
NSString *appId = [appStoreUrl.lastPathComponent stringByReplacingOccurrencesOfString:@"id" withString:@""];

结果:
