Convert NSNumber to NSString and use it in other View

Question

So I have an Array "myArray" with NSNumbers and NSStrings. I need them in another View so i go like this:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

DetailViewController *details = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:nil];
details.subjectText = [[myArray objectAtIndex:indexPath.row] objectForKey:@"subject"];

The subjectText works. But how can I get the Numbers out of it? (I actually need them as strings...) I would convert a String out of a Number like this: NSString *blah = [NSNumber intValue]. But I don't know how to set it up in the code above..

Answer 1

try NSString *myString = [NSNumber stringValue];

Answer 2

[NSString stringWithFormat:@"%i",[NSNumber intValue]];

If you have other numbers than integers, you can replace intValue by floatValue, doubleValue, ... Note that in the format string you need to replace %i by the correct format specifier (%f for double, ..., full list here).

This guide is going to show you how to format NSStrings.

Answer 3

or try NSString *string = [NSString stringWithFormat:@"%d", [NSNumber intValue]];
