Text in UITextField moves up after editing (center while editing)

I have a strange problem. I have an UITextField in which the user should write the amount of something, so the field is called "amountField". Everything looks fine, when the user starts editing the textfield the text is in the vertical and horizontal center - that's great.

However, when the user ends editing the text moves up a little bit. I tried many things, nothing helped...

I am adding screenshots below, so you can see what is the problem.

This is what it looks like while editing the field - that's ok.

This is while editing the field - that's ok.

And this is how it looks when done editing - that is the problem!

This is the problem.

Please, if anybody know what could cause this I would be very grateful! :)

Here is some of my code related to the amountField.

amountField.keyboardType = UIKeyboardTypeNumberPad;
amountField.returnKeyType = UIReturnKeyDone;
amountField.delegate = self;

[amountField setFont:[UIFont fontWithName:@"Nuptial Script LT Std" size:30]];
amountField.borderStyle = UITextBorderStyleNone;
UIImage *amountBg = [UIImage imageNamed:@"skin2_ipad_amountField.png"];
[amountField setBackground:amountBg];

amountField.rightView = nil;
//amountField.backgroundColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:0.2];

amountField.textAlignment = UITextAlignmentCenter;
amountField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
amountField.adjustsFontSizeToFitWidth = YES;
amountLabel.textColor = UIColorFromARGB(0x313030); //Using my own macro

amountField.frame = CGRectMake(300, 480, 136, 32); = CGPointMake(605, 439);

PS: Those white corners are there because I set the background to white with 0.2 alpha, that's ok.

After many hours of trying many things - I have found the problem. In my case the problem is the font. I really don't know why, but the author of the font made the font weird (leading etc.), it has a blank space on the bottom. I don't know why, but when you are editing the text all of the text properties are ignored, but after you finish editing, they are applied.

So, if you have a similar problem, try changing the font to Arial or something similar.

For a full explanation, please consult these following links: link 1 and link 2. The solution recommended in these links can avoid you a lot of headaches and can even be applied to fix problem like text moving to the top when you start editing an UITextField (using System font or other particular fonts).
