In my code I want to know if a method is a class method or an instance method. The code I am currently using works, but I wonder if there is a beter way.
Current code to "detect" if it is a class method or instance:
Method method = class_getInstanceMethod(class, selector);
if (method) {
__strong Class object = [[class alloc] init];
objc_msgSend(object, selector);
}else {
method = class_getClassMethod(class, selector);
if (method) {
objc_msgSend(class, selector);
}
}
There's very little that you can improve beyond two if statements. You can use respondsToSelector: method instead, but since you do not have an object to start with, you will end up with an if inside an if rather than an a better-looking else if:
if ([class respondsToSelector:selector]) {
// Call class method
} else {
id object = [[class alloc] init];
if ([object respondsToSelector:selector]) {
// Call instance method
}
}
If you could modify your program flow to start with an object instead of a class, you coud do this instead:
if ([object respondsToSelector:selector]) {
// Call instance method
} else if ([[object class] respondsToSelector:selector]) {
// Call class method
}
object in the beginning. I edited the answer to start with a class method the same way that you did.
objc_msgSendtoperformSelector:if you really want but there is no real sense to do so.
