iphone - 当 URL 字符串带有空格参数时，找不到 NSURL？

Question

我使用了 UserName=raj 和 pwd=space，但是 NSURL 中没有使用该 url 字符串。

NSString *urlstr = [NSString stringWithFormat:@"http://www.test.com/data/image/sd.php?Uname=raj&password=Space"];

NSURL *Url =  [NSURL URLWithString:urlstr];

Answer 1

如果您从文本字段中获取值，请尝试以下操作：

NSString *urlstr = [NSString stringWithFormat:@"http://www.test.com/data/image/sd.php?Uname=%@&password=%@",[usernameField.text stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding],[passwordField.text stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];

Answer 2

尝试这个 ：-

NSString *urlstr = [NSString stringWithFormat:@"http://www.test.com/data/image/sd.php?Uname=raj&password=Space"];
NSURL *url = [[NSURL alloc] initWithString:
[urlstr stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];

Answer 3

NSURL *url = [NSURL URLWithString:@"http://www.test.com/data/image/sd.php?Uname=raj&password=Space"];
