Given an object, and a method within, is there some way to get the name of the class of the object as an NSString?
For that matter, what I want to do is something like this:
Class MyClass
"MyClass.h"
#import <Foundation/Foundation.h>
@interface MyClass : NSObject
...
-(void)myMethod;
@end
"MyClass.m"
#import "MyClass.h"
@implementation MyClass
...
-(void)myMethod
{
NSString *myClassName = ???; // What can I put here besides a literal @"MyClass"?
NSString *fooText = [NSString stringWithFormat:@"<%@> -(void)myMethod", myClassName];
NSLog(fooText); // Yellow triangle on this line
}
...
@end
so that when the myMethod message is sent to an object of MyClass, the output should be:
<<timestamp>>: <MyClass> -(void)myMethod
on the output pane when debugging - "<<timestamp>>" just comes from the NSLog call.
Also, when I do this (using a literal NSString constant for myClassName above), Xcode marks the line with NSLog with a yellow triangle, and disclosing it says something about passing an NSString instance as being "unsecure". Can this warning be turned off? It seems silly to do:
NSLog(@"%@", fooText);
just to avoid this warning.
By using this strategy, if several classes implement the same message, I can tell which instance received the message during debugging; this is handy when iterating over containers (such as NSArray), and passing the same message to multiple objects, or when passing messages to objects of subclasses that override the behavior of their super.
TIA!
