#import <CoreData/CoreData.h>
@interface Adduser : NSManagedObject
@property (nonatomic, retain) NSString * name;
@property (nonatomic, retain) NSString * password;
@property (nonatomic, retain) NSString * email;
@property (nonatomic, retain) NSString * contact_no;
@property (nonatomic, retain) NSString * address;
@property (nonatomic, retain) NSString * response;
@end

Method 

-(IBAction)signup:(id)sender
{
Registration *adduser=[Registration new];//<-CoreData: error: Failed to call designated initializer on NSManagedObject class 'Registration'
adduser.name=txt1.text;
adduser.password=txt2.text;
adduser.email=txt3.text;
adduser.contact_no=txt5.text;

To create an instance of a managed object class you need to:

Registration *adduser = [NSEntityDescription insertNewObjectForEntityForName:@"Registration" inManagedObjectContext:context];
