PayPal SDK for iOS Another day another dollar. After spending half a day, well I should say wasting half a day I've finally figured out how to add  PayPal's   SDK  for  iOS . 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.) "Adding the Files" - Control Click on your project.xcode file and chose "Add files to project" (or chose File->"Add files to Project"). - Navigate to where you had saved your downloaded  PayPal   SDK  on disk. - You will find a folder named "Library" which contains 11 header files, as well as a static library named " libPayPalMPL .a". - Select all of these files and check the "Copy items into destination group's folder (if needed)  check box . - Now before you build your project you have to add additional libraries. 

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 ); }
