iphone - Why doesn't [obj selectorNotDefined] cause a warning? -

-

i want this:

[myobject selectornotdefined];

will cause warning. there option make happen?

to more specific, when add code existing project:

nsobject *myobject = [[nsobject alloc] init]; [myobject selectornotdefined];

the compiler not invoke warning.

if create new project , add these lines invokes warning.

what's wrong existing project?

if write:

nsobject *myobject = [[nsobject alloc] init]; [myobject selectornotdefined];

you warning: myobject might not respond selector selectornotdefined

or can check: i

f([myobject respondsto:selector(selectornotdefined)]{  [myobject selectornotdefined]; //or [myobject performselector:(selectornotdefined) withobject:nil afterdelay:0];  }
