我正在通过电子邮件正文发送 NSMutableString。它不起作用,因为它说 senderString 不能静态定位。帮助?
NSMutableString *senderString = [[NSMutableString alloc] init];
NSURL *mailURL = [NSURL URLWithString: @"mailto:email@address.com?cc=another@email.com&subject=My%20Subject%20Line&body=%@"], senderString;
[[UIApplication sharedApplication] openURL: mailURL];
