What is the correct string specifier for _cmd?

Question

I use %s for _cmd, the latest XCode will generate an error "Format specifies type char * but the argument has type SEL". Checked documentation and couldn't find a clue. Anyone know the correct string specifier to use?

Answer 1

I've never done Apple programming in my life, so bear with me, but a little Googling revealed easily that:

• to convert SEL to NSString use NSStringFromSelector
• Then use the %@ format specifier on that.
