NSURL length]: unrecognized selector sent to instance 0x89dac30

问题是:

NSString *url = [NSURL URLWithString:@"http://www.mypath.co.uk/ifo.xml"];
NSMutableURLRequest *Request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];

URLWithString 是一个 NSURL 类方法，它返回一个 NSURL 而不是 NSString。更改它并在请求中使用生成的 NSURL 对象，错误将消失。

像这样:

NSURL *url = [NSURL URLWithString:@"http://www.mypath.co.uk/ifo.xml"];
NSMutableURLRequest *Request = [NSMutableURLRequest requestWithURL:url];
