Resize UIImage for Instagram size [iOS]

Question

When I captured the screen and save it as UIImage, the size will be (640x1136) , What I need exactly to set that UIImage center of plain white UIImage to post it into instagram with no crop!

I used this code for resize the UIImage but it doesn't make what I need

UIImage+Resize

from that I used this code:

UIImage *thenew = [NewImg resizedImageWithContentMode:UIViewContentModeScaleAspectFit bounds:CGsizeMake(612,612) interpolationQuality:kCGInterpolationHigh];

Hope you help me with this one
