iOS Warning Error with init override

[JLB-UK]

Hi,

I get the following warning when calling the initWithNumberOfSides from the init method, which is in a init override in a custom class I have created.

 'PolygonShape' may not respond to '-initWithNumberOfSides:minimumNumberOfSides:maximumNumberOfSides:'

The code is as follows

- (id)init { 
	if (self = [super init]) {
		[self initWithNumberOfSides:4 minimumNumberOfSides:3 maximumNumberOfSides:10];
	}
	return self;
}


- (id)initWithNumberOfSides:(int)sides minimumNumberOfSides:(int)min maximumNumberOfSides:(int)max; { 
	if (self = [super init]) {
		[self setMinimumNumberOfSides:min];
		[self setMaximumNumberOfSides:max];
		[self setNumberOfSides:sides];
	}
	return self;
}

The warning error appears however, the code still runs and completes correctly. Could anyone provide any advice on resolving the warning message?

Thanks for the help

Did you declare -initWithNumberOfSides:minimumNumberOfSides:maximumNumberOfSides: in the .h file?

Thank you! Thought I had, but misspelt it! Problem solved! Thanks for your help

Your init override will end up calling super init twice. This is inadvised.

chown's comment is correct.

You should read up on the concept of the designated initializer in the Objective-C 2.0 programming language guide.

You should probably fix it like this

- (id)init { 
	if ((self = [self initWithNumberOfSides:4 minimumNumberOfSides:3 maximumNumberOfSides:10])) {
	}
	return self;
}
