Ios 如何将用户输入到弹出文本字段中的文本存储到NSString中？

我的一些

ViewController.h

NSString *title1;
NSString *sub1;
@interface MapMain : UIViewController
{
    IBOutlet UIButton *setter;
}

都在同一

ViewController.m

-(IBAction)Write:(id)sender
{
    [self alertView];
}

-(void)alertView
{
    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@""
                                                 message:@"Your Info"
                                                 delegate:self
                                                 cancelButtonTitle:@"Cancel"
                                                 otherButtonTitles:@"Done", nil];


    alert.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
    UITextField * alertTextField1 = [alert textFieldAtIndex:0];
    alertTextField1.keyboardType = UIKeyboardTypeDefault;
    alertTextField1.placeholder = @"Name";

    UITextField * alertTextField2 = [alert textFieldAtIndex:1];
    alertTextField2.keyboardType = UIKeyboardTypeDefault;
    alertTextField2.placeholder = @"Username";
    alertTextField2.secureTextEntry = NO;

    [alert show];
}

因此，当我点击一个特定的按钮时，这段代码正确地使一个带有两个文本字段的弹出窗口出现。我如何将用户按下“完成”按钮时输入的文本分别存储到我的

NSString*title1

和

NSString*sub1

中，以便在以后按下其他按钮时使用字符串值。当用户按下“取消”按钮时，如何使我的程序不存储文本？

使您的

MapMain

类符合

UIAlertViewDelegate

协议

@interface MapMain : UIViewController <UIAlertViewDelegate>

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 1) //only if cancel is not clicked (done is clicked)
    {
         UITextField * alertTextField1 = [alertView textFieldAtIndex:0];
         UITextField * alertTextField2 = [alertView textFieldAtIndex:1];
         //... do whatever else you need to here like
         title1 = alertTextField1.text;
    }
}
