NSLog doesnt work with float?

Question

I am trying to do nslog on a float value using :

NSLog(@"THE LOG SCORE : %@", x);

and I have also tried :

NSLog(@"THE LOG SCORE : %@", [NSString stringWithFormat:@"%@", x]);

but it doesnt work! any thoughts why it wouldnt work? the error I get is EXC_BAD_ACCESS

thanks

Solution

The %@ is intended to work on an object, a float is not an object. To do a float try:

NSLog(@"THE LOG SCORE : %f", x);

Here's a helpful article

You must be confusing NSFloat with CGFloat, which is just defined as 'float' and not an object.. Unless there's an NSFloat object i'm not aware of?

There is nothing like NSFloat. stackoverflow.com/questions/6702923/…

For information on other specifiers, see Apple's String Format Specifiers Guide.

And NSInteger and NSUInteger aren't objects neither.

CGFloat is actually a double on 64 bit and a float on 32 bit architectures.

In xcode4, Edit Scheme->Arguments->Environment variables,add NSZombieEnabled,set it to YES.U will locate the mistake.
