Position UILabel when app is opened in iPad - iphone

Question

I have a universal iPhone/iPad app. On the main menu I have a UIImage and UILabel that show the current weather conditions outside; the UILabel shows the current temperature.
I am using the same XIB for both versions, I made all of the graphics I am using a high resolution so they scale good for the iPad.
On the iPhone version, right under the UIImage the label is centered, which is what I want it to do. When it loads in the iPad, the UIImage gets a big bigger, but the label stays in the same position, to the left of the screen, not centered under the bigger image. I have tried many different things in IB to get it to center, and I cannot get it to.
Would it also be possible to make the text size bigger when loaded on the iPad?
Here are some images to portray what I am talking about:

Not sure about your label issue, but to vary text size for iPad create a function to test if you're on an iPad and then use that to vary your code as required. Here's a function to to do the job.
BOOL isIPad()
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
{
return YES;
}
return NO;
}
And then just write some conditional code. For example:
UIButton *infoCircle;
if (isIPad())
{
infoCircle = [UIButton buttonWithType:UIButtonTypeInfoDark];
}
else
{
infoCircle = [UIButton buttonWithType:UIButtonTypeInfoLight];
}
In your case, you'll want to adjust the label font size with something like:
if (isIPad())
{
[[self mainLabel] setFont: [UIFont systemFontOfSize: 18.0]];
}
else
{
[[self mainLabel] setFont: [UIFont systemFontOfSize: 14.0]];
}
If Interface Builder is giving you grief, you can also use the same approach to reposition the UILabel programmatically. Sometimes this is quicker, especially once your interface has settled down.
