What is the Objective-C equivalent for "toString()", for use with NSLog?
nslog, objective-c, tostring
Solution
It is the `description` instance method, declared as:
- (NSString *)description
Here's an example implementation (thanks to grahamparks):
- (NSString *)description {
return [NSString stringWithFormat: @"Photo: Name=%@ Author=%@", name, author];
}
Problem
Is there a method that I can override in my custom classes so that when ``` NSLog(@"%@", myObject) ``` is called, it will print the fields (or whatever I deem important) of my object? I guess I'm looking for the Objective-C equivalent of Java's `toString()`.
