    <p>I am trying to load data.plist string array polygons under NSDictionary(ex. +40.48675,-60.434543) to building. I have 6 index in array. I keep getting warning "Passing argument 7 of initWithID:name:code:number:location:description:polygons from incompatible pointer type." Also the draw polygon doesnt show on map. What ami I missing?</p> <pre><code>NSString *path = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"]; NSArray *array = [[[NSArray alloc] initWithContentsOfFile:path] objectAtIndex:0]; buildings = [[NSMutableArray alloc] init]; for(int i = 0; i &lt; [array count]; i++) { NSMutableDictionary *dic = [array objectAtIndex:i]; NSString *buildingID = [dic objectForKey:@"buildingID"]; NSString *name = [dic objectForKey:@"name"]; NSString *code = [dic objectForKey:@"code"]; NSString *number = [dic objectForKey:@"number"]; //NSString *location = [dic objectForKey:@"location"]; NSString *description = [dic objectForKey:@"description"]; //NSArray *components = [location componentsSeparatedByString:@","]; //NSString *latitude = [components objectAtIndex:0]; //NSString *longitude = [components objectAtIndex:1]; NSArray *polygons = [[NSArray alloc] init]; polygons = [dic objectForKey:@"polygons"]; int countPoints = [self.polygons count]; CLLocationCoordinate2D buildingPoly[countPoints]; for (int i = 0; i &lt; countPoints; i++) { NSArray *splitArrayPoly = [[polygons objectAtIndex:i] componentsSeparatedByString:@","]; buildingPoly[i] = CLLocationCoordinate2DMake([[splitArrayPoly objectAtIndex:0] floatValue], [[splitArrayPoly objectAtIndex:1] floatValue]); } NSArray *splitArray = [ [dic objectForKey:@"location"] componentsSeparatedByString:@","]; float latitude = [[splitArray objectAtIndex:0]floatValue]; float longitude = [[splitArray objectAtIndex:1]floatValue]; CLLocation *tempLocation = [[[CLLocation alloc] initWithLatitude:latitude longitude:longitude]autorelease]; Building *building = [[[Building alloc] initWithID:[buildingID intValue] name:name code:code number:number location:tempLocation description:description polygons:buildingPoly]autorelease]; //This is where I got warning //building.polygons = polygons; // delete this when ure done with init //NSLog(@"building.polygons = %@", building.polygons); // ask teacher about this [buildings addObject:building]; [dic release]; [building release]; } </code></pre> <p>Then in different class "Building.m" it pass polygons to here</p> <pre><code>- (id)initWithID:(int)b_id name:(NSString *)b_name code:(NSString *)b_code number:(NSString *)b_number location:(CLLocation *)b_location description:(NSString *)b_description polygons:(NSArray *)b_polygons { self = [super init]; if (self != nil) { self.buildingID = b_id; self.name = b_name; self.location = b_location; self.code = b_code; self.number = b_number; self.description = b_description; self.polygons = b_polygons; } return self; } </code></pre> <p>Then this method should get all polygons and make it on map. However it doesn't show anything.</p> <pre><code>- (MKPolygon *)getPolygons{ int countPoints = [self.polygons count]; CLLocationCoordinate2D building[countPoints]; for (int i = 0; i &lt; countPoints; i++) { NSArray *splitArray = [[polygons objectAtIndex:i] componentsSeparatedByString:@","]; building[i] = CLLocationCoordinate2DMake([[splitArray objectAtIndex:0] floatValue], [[splitArray objectAtIndex:1] floatValue]); } return [MKPolygon polygonWithCoordinates:building count:countPoints]; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
