NSArray add objects from other array

Question

I have three NSArray objects. I need to add all objects for this array to NSArray that is called allMyObjects.

Have NSArray standard solution to make it for example via initialization method or do I need make custom method to retrieve all objects from other arrays and put all retrieved objects to my allMyObjects array?

Answer 1

once see this one ,

NSArray *newArray=[[NSArray alloc]initWithObjects:@"hi",@"how",@"are",@"you",nil];
    NSArray *newArray1=[[NSArray alloc]initWithObjects:@"hello",nil];
    NSArray *newArray2=[[NSArray alloc]initWithObjects:newArray,newArray1,nil];
    NSString *str=[newArray2 componentsJoinedByString:@","];
    NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"()\n "];
    str = [[str componentsSeparatedByCharactersInSet:doNotWant] componentsJoinedByString: @""];
     NSArray *resultArray=[str componentsSeparatedByString:@","];
    NSLog(@"%@",resultArray);

O/P:-

(
    hi,
    how,
    are,
    you,
    hello
)
