UITextField attributedPlaceholder has no effect

I'm trying to format the placeholder text of a UITextField using an NSAttributedString. This code works successfully for the foreground color and kerning attributes. However, it won't change the font or the font size. What am I doing wrong? Thanks!
NSAttributedString *aString = [[NSAttributedString alloc] initWithString:
#"USER NAME"
attributes:#{
NSForegroundColorAttributeName: [UIColor redColor],
NSFontAttributeName : [UIFont fontWithName:#"Georgia" size:8.0f],
NSKernAttributeName : [NSNumber numberWithFloat:3.0f]
}];
self.userNameTextField.attributedPlaceholder = [aString copy];

Answer 1

For me it works when I set custom font for UITextField, and then set other attributes for placeholder. My example that works:
_searchField.font = [UIFont fontWithName:fontRokkitRegular size:20];
UIColor *color = [UIColor colorWithRed:150.0f/255 green:150.0f/255 blue:150.0f/255 alpha:1];
_searchField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:#"Keyword search" attributes:#{NSForegroundColorAttributeName:color}];

It looks like the placeholder font size is governed by the UITextField's font so I think you will have to subclass UITextField and add:
-(void)drawPlaceholderInRect:(CGRect)rect
{
NSString *aString = #"USER NAME";
[aString drawInRect:rect withAttributes:#{NSForegroundColorAttributeName: [UIColor redColor], NSFontAttributeName : [UIFont fontWithName:#"Georgia" size:8.0f], NSKernAttributeName : [NSNumber numberWithFloat:3.0f]}];
}
