I'm currently using  XCode  4. I will break it down into steps so hopefully this will help others! 1.)  SDK  Download. - First you have to download the  PayPal   iOS   SDK  from  here . 2.)

Crop the image //Croping start from x=0; y=0; and till width=125 and height=128; UIImage * image = imageView . image ; CGRect cropRect = CGRectMake ( 0 , 0 , 125 , 128 ); CGImageRef imageRef = CGImageCreateWithImageInRect ([ image CGImage ], cropRect ); [ imageView setImage :[ UIImage imageWithCGImage : imageRef ]];   CGImageRelease ( imageRef ); Mask Image - ( UIImage * ) maskImage : ( UIImage * ) image withMask : ( UIImage * ) maskImage {   CGImageRef maskRef = maskImage.CGImage;   CGImageRef mask = CGImageMaskCreate ( CGImageGetWidth ( maskRef ) , CGImageGetHeight ( maskRef ) , CGImageGetBitsPerComponent ( maskRef ) , CGImageGetBitsPerPixel ( maskRef ) , CGImageGetBytesPerRow ( maskRef ) , CGImageGetDataProvider ( maskRef ) , NULL , false ) ;   CGImageRef masked = CGImageCreateWithMask ( [ image CGImage ] , mask ) ; return [ UIImage imageWithCGImage : masked ] ;   }

When you want user to enter only number (like in case of mobile number) then you can restrict using this 1. Put a macro before @implementation        #define NUMERIC @"1234567890" 2. textField DelegateMethod       - ( BOOL ) textField :( UITextField *) textField shouldChangeCharactersInRange :( NSRange ) range replacementString :( NSString *) string { NSCharacterSet * unacceptedInput = nil ; if ( textField == self . phoneTextField ) { unacceptedInput = [[ NSCharacterSet characterSetWithCharactersInString : NUMERIC ] invertedSet ]; } return ([[ string componentsSeparatedByCharactersInSet : unacceptedInput ] count ] <= 1 ); }
