我试图将UIAlertView从屏幕中心的默认位置移动到顶部。我正在使用下面的代码,它适用于iOS 4,但它不会继续。3.
任何人有任何想法?CGAffineTransformTranslate无法在iOS 3.1.3中工作
UIAlertView *newSubscriptionAlertView = [[UIAlertView alloc] initWithTitle:@"Ndrysho abonimin" message:@" " delegate:self cancelButtonTitle:@"Anullo" otherButtonTitles:@"Ruaj", nil]; subscriptionNameField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 22.0)]; subscriptionNameField.text = [[subscriptions objectAtIndex:changeCode] title]; subscriptionNameField.autocorrectionType = UITextAutocorrectionTypeNo; subscriptionNameField.autocapitalizationType = UITextAutocapitalizationTypeNone; [subscriptionNameField setBackgroundColor:[UIColor whiteColor]]; [newSubscriptionAlertView addSubview:subscriptionNameField]; [subscriptionNameField becomeFirstResponder]; [subscriptionNameField release]; CGAffineTransform moveUp = CGAffineTransformTranslate(newSubscriptionAlertView.transform, 0.0, 0.0); [newSubscriptionAlertView setTransform:moveUp]; [newSubscriptionAlertView show]; [newSubscriptionAlertView release];
我不知道你期待发生什么,但'CGAffineTransformTranslate(someTransform,0,0)'只是要返回'someTransform'回您。 –
,这就是为什么setTransform方法在下面一行使用。我认为语法是好的,因为它可以在iOS 4.0+上工作。 – Olsi
即使我这样做:newSubscriptionAlertView.transform = CGAffineTransformTranslate(newSubscriptionAlertView.transform,0.0,0.0);我也有同样的问题。这意味着它在4上工作,但不在3上。:( – Olsi
