Displaying the contents of an NSMutableArray in a UITextView

I have this array, NSSMutableArray *myarray, which has five objects in it, and I am using a loop like this: 

for( className *myObject in myarray)
{
    myTextview.text = [NSString stringWithFormat:@"the name is %@", myObject];
}

When I build and run, only the last name shows in my UITextView *myTextview. I logged it, and my loop is working fine -- it's showing all five objects.

The problem seems to be that each time an object is sent to the myTextView, the next object replaces it; is there a way I can hold all of them, so the whole array can be shown?

Each time you pass the loop you are replacing myTextview.text. What you want is to add to the string each time. Try this:

NSMutableString *string = [NSMutableString string];
for( className *myObject in myarray) {
    [string appendString:[NSString stringWithFormat:@"the name is %@\n", myObject]];
}
myTextview.text = string;
