当你在App里点击分享链接时,是否见过类似「%E4%BD%A0%E5%A5%BD」的乱码?这些神秘符号其实是经过编码的URL!今天就带你揭开iOS开发中URL解码的神秘面纱。
URL中不能直接使用以下特殊字符:
假设遇到已编码字符串:”https%3A%2F%2Fexample.com%3Fq%3D咖啡”
let encoded = "https%3A%2F%2Fexample.com%3Fq%3D%E5%92%96%E5%95%A1" if let decoded = encoded.removingPercentEncoding { print(decoded) // 输出完整URL }
extension String { func safeUrlDecode() -> String? { let preprocessed = self.replacingOccurrences(of: "+", with: "%20") return preprocessed.removingPercentEncoding } }
在Xcode中使用快速检测:
po encodedString.removingPercentEncoding? ?? "解码失败"
小编观点:URL解码就像拆快递包裹,用对工具才能安全取出内容。下次看到%符号别慌张,用对方法就能让乱码现原形!记得处理特殊字符时戴上「防护手套」(异常处理),你的App就能完美消化各种链接啦~
