Rotation Transformation for UITextField, but text is displaced

I am trying to rotate UITex开发者_Go百科tField at 90 angle.It is rotationg perfectly..but text inside the UITextField, is displaced.I am unable to find out the reason behind it.

[InputField setTransform:CGAffineTransformMakeRotation(-M_PI / 2.0)];
    [InputField setContentVerticalAlignment:UIControlContentVerticalAlignmentTop];
    [InputField setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];

works for me!

What exactly is the problem? When I apply an CGAffineTransformation to an TextField, everything looks fine.

myTextField.transform = CGAffineTransformMakeRotation(M_PI_2);

Instead of setting the vertical and horizontal alignment (which produces the off-center edit window observed above), you could handle the editing rect manually. I overrided editingRectForBounds as follows. This centers the editing rect regardless of rotation:

-(CGRect)editingRectForBounds:(CGRect)bounds
{
    // how tall is the font?
    CGFloat fontHeight = [self.text sizeWithFont:self.font].height;

    // compute pad 
    CGFloat pad = (bounds.size.height - fontHeight) / 2.0f;

    // return rect with pad on top and bottom
    return CGRectMake(bounds.origin.x, bounds.origin.y + pad, bounds.size.width, fontHeight);
}
