我正在尝试将 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,它可以在 iOS 4 上运行,但在 3 上却没有。
有人知道吗?
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 = [[订阅 objectAtIndex:changeCode] title];
subscriptionNameField.autocorrectionType = UITextAutocorrectionTypeNo;
subscriptionNameField.autocapitalizationType = UITextAutocapitalizationTypeNone;
[subscriptionNameField setBackgroundColor:[UIColor whiteColor]];
[newSubscriptionAlertView addSubview:subscriptionNameField];
[订阅名称字段成为FirstResponder];
[订阅名称字段发布];
CGAffineTransform moveUp = CGAffineTransformTranslate(newSubscriptionAlertView.transform, 0.0, 0.0);
[newSubscriptionAlertView setTransform:moveUp];
[newSubscriptionAlertView 显示];
[newSubscriptionAlertView 发布];
