iOS从URL字符串中删除特殊字符[关闭]

Question

我想使用 NSURLRequest 调用这个 URL：

http://www.test.com/query={"tag1":"üğişi","tag2":"çöçödd"}

这些字符是“üğişi”和“çöçödd”UTF8 字符。我需要转换此 URL 以获得响应。你能帮帮我吗？

使用NSString 类的-(NSString*)stringByAddingPercentEscapesUsingEncoding:(NSStringEncoding)encoding; 例程。像这样：

NSString* url = @"http://www.test.com/query={\"tag1\":\"üğişi\",\"tag2\":\"çöçödd\"}"; 
NSString* urlEncoded = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
