Question

I am trying to call a method from another class which is in another source file.

Example:

1. I have a file named Source1.h/Source1.m (both are objective C class files)
2. I have another file names Source2.h/Source2.m (both are objective C class files)
3. Source1 contains 2 methods eg: method1 and method2.
4. From Source2 file, I need to call the method1 from source1 file.

I know how to do that in objective C. But in my source2 file, the method names in Source1 will be retrieved dynamically. I am not going to hard code it some thing similar to this.

Source1 *a = [[Source1 alloc]init];

[a method1];

The method1 text will taken from a text file. I can use Selector to invoke a method from same class. But I can’t use selector to call method from another class.

Please help to solve this issue….

Many Thanks……

This answer seems to be relevant: How can I dynamically create a selector at runtime with Objective-C?

Basically you can use NSSelectorFromString to make a selector from an UTF8 string in an NSString.
