我想将NSArray添加到我的NSMutable(appdelegate中的init)
这是我的代码,每次按下按钮(男性,女性,情侣)时都会调用该方法,因此必须将NSArray添加到MutableArray中,但我不知道我尝试过但不起作用。 :
- (void) sexChoosen:(NSString *) sexe
{
NSError *err;
NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Boxes" inManagedObjectContext:context];
[request setEntity:entity];
NSArray *arrayForPredicate = [context executeFetchRequest:request error:&err];
NSPredicate *sex;
sex = [NSPredicate predicateWithFormat:@"sexe = %@", sexe];
NSArray *BoxWithSex = [arrayForPredicate filteredArrayUsingPredicate:sex];
//NSMutableArray* tmp = [self createMutableArray:BoxWithSex];
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSLog(@"FIRST %@", appDelegate.myArray);
// HERE IS THE CODE TO ADD THE ARRAY TO MY NSMUTABLE ARRAY = AppDelegate *appDelegate
NSLog(@"SECOND %@", appDelegate.myArray);
}

来自NSMutableArray documentation:
“addObjectsFromArray:添加另一个给定数组中包含的对象 到接收数组内容的末尾。“
