How make a Rect for tiles from a Tiled Map - cocos2d-iphone

Question

For my collision detection I need to check of the ball rect intersects any of the wall rects. Right now I have it working but its checking to see if the ball's position is at one of the tile's GID, using this.
-(void) checkHits:(CGPoint)position {
CGPoint tileCoord = [self tileCoordForPosition:position];
int tileGid = [levelLayer tileGIDAt:tileCoord];
//NSLog(#"%g",tileRect.origin);
if (tileGid) {
NSDictionary *properties = [level propertiesForGID:tileGid];
if (properties) {
NSString *collision = [properties valueForKey:#"break"];
if (collision && [collision compare:#"True"] == NSOrderedSame) {
//for blocks
//[[SimpleAudioEngine sharedEngine] playEffect:#"hit.caf"];
[levelLayer removeTileAt:tileCoord];
velocity.y *= -1;
}
if (collision && [collision compare:#"False"] == NSOrderedSame) {
//for edges
//[[SimpleAudioEngine sharedEngine] playEffect:#"hit.caf"];
velocity.y *= -1;
}
}
}
}
I need to know how to change this to checking to see if the balls rect/boundingbox intersects with any of the tiles rects/boundingboxex(and how to get the tiles rect/boundingbox in the first place) that have the property break.
P.S. I'm using the Tiled map editor.

Answer 1

Figured this out a little while ago:
CCSprite *tile;
for (int i = 0; i < level.contentSize.width/level.tileSize.width; i ++)
for (int j = 0; j < level.contentSize.height/level.tileSize.height; j ++){
tile = [levelLayer tileAt:ccp(i,j)];
if (CGRectIntersectsRect(ball.boundingBox, tile.boundingBox)) {
//Do whatever...
}
}
}
I recommend having a collide layer to make map making easier.
