Question

I’m developing an iPhone 4 application and I having problems with the class:

    @interface Pattern : NSObject {

        int maxNumShapes;
        NSMutableArray* shapes;
        NSMutableArray* shapeMatched;
        CGSize bounds;
    }
    @property (nonatomic, retain, readonly) NSMutableArray* shapes;
    @property (nonatomic, retain, readonly) NSMutableArray* shapeMatched;

    ...
    - (void) setShapeMatched:(ShapeType)type;

@end

And its implementation:

- (void) setShapeMatched:(ShapeType)type {
    int index = 0;
    if (shapes != nil)
    {
        for(Object2D* obj in shapes)
        {
            if (obj.figure == type)
            {
                [shapeMatched replaceObjectAtIndex:index 
                                        withObject:[NSNumber numberWithBool:YES]];
                obj.withFillColor = YES;
                break;
            }
            else
                index++;
        }
    }
}

I get the following warning:

Type of property 'shapeMatched' does not match type of accessor 'setShapeMatched:'

How can I fix this warning?

You need to rename your custom setShapeMatched: to something else (like setMyShapeMatched). setShapeMatched: is already in use as the setter for your declared property.
