ios - What will happen if my class conforms to two protocols having same property? -

let's have 2 protocols

@protocol playlist<nsobject> @property(nonatomic, copy) nsstring *title; @property(nonatomic, assign) nsuinteger trackcount; @end 

and as

@protocol album<nsobject> @property(nonatomic, copy) nsstring *name; @property(nonatomic, assign) nsuinteger trackcount; @end 

and there class conforms these protocols

.h file

@interface musiclibrary <playlist, album> @end 

.m file

@implementation musiclibrary @synthesize title; @synthesize name; @synthesize trackcount; @end 

which trackcount property refer to? can use trackcount twice?

it surely not give compile time error.

it looks me modeling data wrong. way have setup musiclibrary both playlist , album. think more correct model have musiclibrary containing many playlist , many albums. like:

@property (nonatomic, strong) nsarray<album>* albums; @property (nonatomic, strong) nsarray<playlist>* playlists;
