Question

Im getting two warnings when i build and run my code. The App still works and it doesn’t crash but I don’t understand why I’m getting the two warnings. The first warning is listed in the title and the second warning states “Method ‘-checkForAndResolveCollisions’ not found.

-(id) init
{

if( (self=[super init]) ) {

    CCLayerColor *blueSky = [[CCLayerColor alloc] initWithColor:ccc4(100, 100, 250, 255)];
    [self addChild:blueSky];

    map = [[CCTMXTiledMap alloc] initWithTMXFile:@"level1.tmx"];
    [self addChild:map];

    player = [[Player alloc] initWithFile:@"koalio_stand.png"];
    player.position = ccp(100, 50);
    [map addChild:player z:15];

    [self schedule:@selector(update:)];

    walls = [map layerNamed:@"walls"]; *

}
return self;

}

-(void)update:(ccTime)dt
{
[player update:dt];

[self checkForAndResolveCollisions:player]; **
}

Title warning is shown on the line with *
The method not found warning is shown on the line with **

Looks like you simply need to add the method declaration for “checkForAndResolveCollisions:” to that class .h / @interface file.
