Question

I am trying to display an NSNumber from an array with keys into an UILabel. Here is my current code: marblesNeeded.text = [[[records objectAtIndex:0] valueForKey: @"marblesneeded"] intValue];

I also get the error:
warning: Semantic Issue: Incompatible integer to pointer conversion assigning to 'NSString *' from 'int'


Thanks

You need to create an NSString to set the text of a UILabel.

marblesNeeded.text = [NSString stringWithFormat:@"%i",[[[records objectAtIndex:0] valueForKey: @"marblesneeded"] intValue]];

In the format %i denotes that you will be providing an integer value after the format.

Edit:

As some comments have noted NSNumber does have a stringValue, it does work but is not my personal preference because it gives you little control as to the format of the string. Consider this example.

NSNumber *number = [NSNumber numberWithFloat:3.25];
NSLog(@"%@",number.stringValue);  // Will print 3.25
NSLog(@"%@",[NSString stringWithFormat:@"%i",number.intValue]); // Will print 3

Since the question envolved printing an intValue this more explicit format may be necessary.
