I am trying to develop a application by using Cocos2d. I can't getting value from textfield . How can get the value of text field (in a alert view) by using Cocos2d ?
-(void)timed1: (id)sender
{
UIAlertView* dialog = [[[UIAlertView alloc] init] retain];
[dialog setDelegate:self];
[dialog setTitle:@"Enter Time:"];
[dialog setMessage:@" "];
UITextField * nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
[dialog addSubview:nameField];
[nameField setBackgroundColor:[UIColor whiteColor]];
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 70.0);
[dialog setTransform: moveUp];
[dialog setBackgroundColor:[UIColor clearColor]];
[dialog addButtonWithTitle:@"Done"];
[dialog show];
nameField.clearButtonMode = UITextFieldViewModeWhileEditing;
nameField.keyboardType = UIKeyboardTypeNumbersAndPunctuation;
nameField.keyboardAppearance = UIKeyboardAppearanceAlert;
nameField.autocapitalizationType = UITextAutocapitalizationTypeWords;
// timeStatus is a int type global variable
timeStatus =[nameField.text intValue]; // this line not working i can't getting value namefield
[dialog release];
[nameField release];
}
Action sheets and alerts are handled asynchronously. In your case, the message [dialog show] merely schedules the show event for some later execution (handled by the main run loop). If you put in a few NSLog()s, you'll see that the [show] message returns almost immediately, at which point your user hasn't entered any data, nameField's text is blank, and this converts to an int of 0.
You want a blocking, modal dialog with input -- action sheets and alerts are not designed for user input beyond yes/no/cancel button pushes. You'll have to cook up a view of your own: not too hard, but it will require more work than using an action sheet/alert.
