Programmatic controls appearing at different times

Question

Here's a weird one. I'm playing around with programmatic controls (as opposed to those created and connected in IB), and in my viewDidLoad function, I create a textbox and button as below.
I animate into this view using a spin motion, based on the sample utility template, that all works great.
The weird part is that the text box is visible during the spin, and the button doesn't appear until just after the spin is complete.
Is there something different about those controls, or am I forgetting an important property of the button that affects when it becomes visible?
Thanks in advance for any thoughts...
-(void)viewDidLoad
[super viewDidLoad];
CGRect frame = CGRectMake(20.0, 68.0, 280.0, 31.0);
UITextField *aTextField = [[UITextField alloc] initWithFrame:frame];
aTextField.textAlignment = UITextAlignmentCenter;
aTextField.borderStyle = UITextBorderStyleRoundedRect;
aTextField.autocapitalizationType = UITextAutocapitalizationTypeWords;
aTextField.keyboardType = UIKeyboardTypeNamePhonePad;
aTextField.returnKeyType = UIReturnKeyDone;
[self.view addSubview:aTextField];
CGRect frame2 = CGRectMake(20.0, 100.0, 100.0, 31.0);
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = frame2;
[self.view addSubview:btn];

I pasted your code into FlipsideViewController.m and it seems to work fine. I can't reproduce the delayed visibility you reported. Are you seeing this behavior on both the Simulator and the Device? Is your code in that same file? What changes have you made to the template, especially RootViewController.m?
