@interface MemberModel : NSObject
@property(nonatomic,copy)NSString *name; //名字
@property(nonatomic,copy)NSString *code; //编码
@property(nonatomic,copy)NSString *avatarUrl; //头像
@end

MemberModel *model1 = [MemberModel New];
MemberModel *model2 = [MemberModel New];
MemberModel *model3 = [MemberModel New];
model1.name = @"J";
model2.name = @"JJ"
model2.name = @"JJJ"
NSArray *array1 = @[model1,model2,model3];

MemberModel *model4 = [MemberModel New];
MemberModel *model5 = [MemberModel New];
MemberModel *model6 = [MemberModel New];
model4.name = @"Jj";
model5.name = @"JJ"
model6.name = @"JJ11J"
NSArray *array2 = @[model4,model5,model6];

I want to filter of the same model's name in the two array this is my code:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"NOT (self.name IN %@)", [array2 valueForKey:@"name"]];
NSArray *source = [array1 filteredArrayUsingPredicate:predicate];

but not use , please tell me how to solve ， thanks

It is hard for people to understand what you want. All you said is "I want to filter of the same model's name in the two array this is my code but not use" –  Mar 02 '17 at 01:54
