Question

我现在用一些alertViews进行实验。现在尝试使用两个textField来设置AlertView。当我点击“完成”时，它应该显示一个日志。

目前，代码看起来像这样：

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Titel" message:@"Message" delegate:self cancelButtonTitle:@"Done" otherButtonTitles:@"Cancel", nil];

TextField应该有占位符。我该如何设置？

试试这个：它应该有效：

 UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Your_Title" message:@"Your_message" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
[av setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];

// Alert style customization 
[[av textFieldAtIndex:1] setSecureTextEntry:NO];
[[av textFieldAtIndex:0] setPlaceholder:@"First_Placeholder"];
[[av textFieldAtIndex:1] setPlaceholder:@"Second_Placeholder"];
[av show];

您可以访问alertView:clickedButtonAtIndex: UIAlertViewDelegate上文本字段的值。

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
     NSLog(@"1 %@", [alertView textFieldAtIndex:0].text);
     NSLog(@"2 %@", [alertView textFieldAtIndex:1].text);
}

带有textField的UIAlertView
