Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is,

What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code,

Interface:

@interface myClass : NSObject {

    NSString *myClass_name;  // LINE 1
}

@property(nonatomic, retain) NSString *myClass_name;  // LINE 2

@end

Implementation:

@implementation myClass

@synthesize myClass_name  // LINE 3

@end

Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?
