问题
So the new iOS 7 has come out and I'm trying to add multiple textFields and labels to the UIAlertviews. I need three. I've been trying to add them as subviews and that doesn't work anymore. I have also tried to add multiple lines with the UIAlertViewStylePlainTextInput but it only seems to return one text field.
I need to add in labels to show them what to enter as well. Is there a way to accomplish this task with the new iOS 7?
回答1:
The only solution i found using UIAlertView with more than one text field in iOS7 is for login only.
use this line to initialize your alertView
[alert setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];
and this to grab the users input:
user = [alert textFieldAtIndex:0].text;
pw = [alert textFieldAtIndex:1].text
For other purposes than login view the other threads like this on: UIAlertView addSubview in iOS7

You can change accessoryView to any own customContentView in a standard alert view in iOS7
[alertView setValue:customContentView forKey:@"accessoryView"];
Note that you must call this before [alertView show].
Simplest illustrating example:
UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"TEST" message:@"subview" delegate:nil cancelButtonTitle:@"NO" otherButtonTitles:@"YES", nil];
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 50)];
v.backgroundColor = [UIColor yellowColor];
[av setValue:v forKey:@"accessoryView"];
[av show];

If you want to add just two textfields to your UIAlertView, you can use UIAlertViewStyleLoginAndPasswordInput and modify the textfields as follows:
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Some Title" message:@"Some Message." delegate:self cancelButtonTitle:@"Okay" otherButtonTitles:@"No, thanks", nil];
alert.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
[alert textFieldAtIndex:1].secureTextEntry = NO; //Will disable secure text entry for second textfield.
[alert textFieldAtIndex:0].placeholder = @"First Placeholder"; //Will replace "Username"
[alert textFieldAtIndex:1].placeholder = @"Second Placeholder"; //Will replace "Password"
[alert show];
Afterwards, in the UIAlertView delegate, you can simply get the text using:
text1 = [alert textFieldAtIndex:0].text;
text2 = [alert textFieldAtIndex:1].text;
