将字符串转换为 url

Question

当我将字符串转换为 NSURL 时，我得到了一些东西。我的代码 id...

NSString *urlString = [[NSString alloc]initWithFormat:@"http://host name/index.php?id=%@&mob=%@&name=%@&mail=%@&m=23", self.deviceId, self.pnumber, self.name, self.email];
urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
NSURL *urlPattern = [NSURL URLWithString:urlString];
NSLog(@"%@", urlPattern);

如何将字符串转换为 NSURL

Answer 1

可能您正在将文本字段分配给 urlString。检查 self.pnumber 是文本字段还是字符串。如果 textField 然后设置为 self.pnumber.text 并类似地检查所有数据。

将self.pnumber, self.name, self.email更改为self.pnumber.text, self.name.text, self.email.text

像这样使用

NSString *urlString = [[NSString alloc]initWithFormat:@"http://host name/index.php?id=%@&mob=%@&name=%@&mail=%@&m=23", self.deviceId, self.pnumber.text, self.name.text, self.email.text];

Answer 2

试试这个

let NSHipster = URL(string: "http://nshipster.com/") //returns 一个有效的 URL

让无效URL = URL(string: "www.example.com/This is a sentence") //Returns nil
