Textview Help!!!

[atothendrew]

I'm trying to display my array "main_array" into a textview. but when i do, i only get the number in the last array slot.

Code: (Objective-C)

for(x=0;x<=size_int;x++)
	{
		main_array[x] = (rand() % max_int) + 1;
		textview.text =[NSString stringWithFormat:@"myNumber: %i\n", main_array[x]];
	}

for some reason it erases itself each time the loop is processed.

could i do something like:

Code: (Objective-C)

textview.text = textview.text[NSString stringWithFormat:@"myNumber: %i\n", main_array[x]];

any ideas? suggestions? i really need help...

How do you declare main_array?  Is it a C-style array of type double or is it an NSMutableArray?

It seems like you're  overwriting the text field each time through the loop with the next array element.  So by the end of the for loop, all you have is the last entry in the entry to display.  Perhaps you want to build up a single string by using the stringByAppendingString: method so that you concatenate each successive element to the end of a string each time through the loop.  Then once the loop is over you can display the resulting string.

Anyway, that's just my take on what I think you're trying to accomplish.
