How to get an int in decimal from a Hex NSString

I would like to get a dec value from a Hex-encoded string, for examples: A->10, B->11,etc. and I coded as the following

NSString *tempNumber;
tempNumber=number.text; 
NSScanner *scanner=[NSScanner scannerWithString:tempNumber];
unsigned int temp;
[scanner scanHexInt:temp];
NSLog(@"%@:%d",tempNumber,temp);

but the NSLog output isn't what I perfer..

You should use 

[scanner scanHexInt:&temp];

scanHexInt: expects a pointer, not a value.
