I tried the solution for your question.If you use alertViewController with textField you can't set multiple line.For label you can set multiple line but for textfield you can't set.
#import "ViewController.h"
#interface ViewController ()<UITextFieldDelegate>
{
NSArray *arr;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
arr = [NSArray arrayWithObjects:#"iOS",#"Android",#"Windows",nil];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)actionShowClickTextField:(id)sender
{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
message:#"Enter your text"
preferredStyle:UIAlertControllerStyleAlert];
[alertController addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.delegate = self;
textField.text = #"";
for(int i=0;i<[arr count];i++)
{
textField.text = [textField.text stringByAppendingString:[NSString stringWithFormat:#"%#,\n",[arr objectAtIndex:i]]];
}
NSLog(#"The textField text is - %#",textField.text);
}];
[self presentViewController:alertController animated:YES completion:nil];
UIAlertAction *actionAlert = [UIAlertAction actionWithTitle:#"Save"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
// access text from text field
NSString *text = ((UITextField *)[alertController.textFields objectAtIndex:0]).text;
NSLog(#"The text is- %#",text);
}];
actionAlert.enabled = YES;
[alertController addAction:actionAlert];
}
#end
The printed output results are
The textField text is - iOS, Android, Windows

UITextFIeld is specific to one line. you cannot have multi-line textfeild. IF you need multi line , you should go for UITextView. Again you cannot add UITextView to the alert controller. You need to build a custom alert view.
