NSAssert undeclared first use why?

i used the code below in the levelManager.m to read values from a plist but when I am making an Archive to upload to itunes (AppStore) I get an error. why ?

the code :

- (float)floatForProp:(NSString *)prop {
NSNumber * retval = (NSNumber *) [_curStage objectForKey:prop];
NSAssert (retval != nil, @"Couldn't find prop %@", prop);
return retval.floatValue;
}

the error:

NSAssert undeclared first use

Note I notice that xcode is thinking that I am giving NSAssert 3 parameters instead of 2

Solution

  • You could use one of the NSAssert variants, in your case NSAssert1:

    #define NSAssert1(condition, desc, arg1)

    So:

    #import <Foundation/Foundation.h>

- (float)floatForProp:(NSString *)prop
{
  NSNumber * retval = (NSNumber *) [_curStage objectForKey:prop];
  NSAssert1 (retval != nil, @"Couldn't find prop %@", prop);
  return retval.floatValue;
}
