ios - Comparing two arrays with NSPredicate -

i've 2 array, 1 represents list of full-size images , other 1 represents images' thumbnail. there way, using nspredicate, check if full-size image has thumbnail?

the thumb called img{number}_thumb.jpg , full-size image called img{number}.jpg.

using arrays, strings , loop :

nsarray *thumbs=@[@"img1_thumb.jpg",@"img2_thumb.jpg",@"img3_thumb.jpg",@"img4_thumb.jpg",@"img5_thumb.jpg",]; nsarray *images=@[@"img1",@"img2",@"img3",@"img41",@"img5"];  bool issame=yes; (nsstring *name in images) {     if (![thumbs containsobject:[nsstring stringwithformat:@"%@_thumb.jpg",name]]) {         issame=no;         nslog(@"%@ doesn't has thumb image",name);         break; //if first not found not enough remove break     } } nslog(@"%@",issame?@"all thumb has image":@"all thumb not have image");

using nspredicate:

for (nsstring *image in images) {     nspredicate *predicate=[nspredicate predicatewithformat:@"self [c]%@",[nsstring stringwithformat:@"%@_thumb.jpg",image]];     nsarray *filtered=[thumbs filteredarrayusingpredicate:predicate];     if (filtered.count==0) {         nslog(@"%@ not found",image);     } }
