Question

我有这段代码：

    if (email.text == emailComfirm.text) {
        UIAlertView *emailAllertView = [[UIAlertView alloc] initWithTitle:@"Succes" message:@"Yaaay, je kan nu gebuik gaan maken van Vogelspotter." delegate:self cancelButtonTitle:@"Direct aanmelden" otherButtonTitles: nil];
        [emailAllertView show];
        // Doing some other code here
        [self dismissModalViewControllerAnimated:YES];
    }else{
        NSLog(@"email: %@", email.text);
        NSLog(@"email: %@", emailComfirm.text);

        UIAlertView *emailAllertView = [[UIAlertView alloc] initWithTitle:@"Foutmelding" message:@"De opgegeven email adressen komen niet met alkaar overeen" delegate:self cancelButtonTitle:@"Probeer het nog eens" otherButtonTitles: nil];
        [emailAllertView show];
    }

不知何故，如果我输入ee / ee或ee / ff，我就不会在textfiels中键入moather wath，如果我输入ee / ee或ee / ff，那么该语句总是会传给其他人。有人能告诉我我做错了吗？

提前tnx。

您想使用[email.text isEqualToString:emailComfirm.text]来比较2个NSString *对象的内容。使用==将比较2个对象的地址，而不是对象的内容。这就是指针的工作方式How do pointer to pointers work in C?

textfield文本内容比较不起作用
