After importing entire paypal library use this code
#import "PayPal.h"
typedef enum PaymentStatuses {
PAYMENTSTATUS_SUCCESS,
PAYMENTSTATUS_FAILED,
PAYMENTSTATUS_CANCELED,
} PaymentStatus;
#interface Paybypal : UIViewController<PayPalPaymentDelegate>{
#private
CGFloat y;
BOOL resetScrollView;
PaymentStatus status;
}
#property(nonatomic,retain)NSString *details;
#property(nonatomic,retain)NSDecimalNumber *totalvaluemin;
in .m file

#import "PayPalInvoiceItem.h"
#import "SuccessViewController.h"
#define SPACING 3.
#interface Paybypal ()
#end
