Show MKMapView in UITableViewCell without slow down UI

Question

i\'m trying to put a MKMapView in some UiTableViewCell but (on iPhone 5, so even in other devices), when the app load the cell with the map, the scroll become not too smooth

Answer 1

I ended up using MKMapSnapshotter for the devices that support this awesome and fast function and using Google Static Maps Api for the devices that run iOS6. I think is the best and fast solution that i can get.

Thanks to @Rob for the suggestion.

if ( IS_IOS7 ) {

    // Placeholder
    cell.objectImage.image = [UIImage imageNamed:@"mapPlaceholder"];

    // Cooridinate
    MKCoordinateRegion region;
    region.center = activity.object.location.coordinate;
    MKCoordinateSpan span;
    span.latitudeDelta = 0.055;
    span.longitudeDelta = 0.055;
    region.span = span;
    [self.mapViewForScreenshot setRegion:region animated:NO];

    MKMapSnapshotOptions *options = [[MKMapSnapshotOptions alloc] init];
    options.region = self.mapViewForScreenshot.region;
    options.scale = [UIScreen mainScreen].scale;
    options.size = CGSizeMake(300, 168);

    MKMapSnapshotter *snapshotter = [[MKMapSnapshotter alloc] initWithOptions:options];
    [snapshotter startWithCompletionHandler:^(MKMapSnapshot *snapshot, NSError *error) {

        UIImage *image = snapshot.image;
        [cell.objectImage setImage:image];
        cell.mapPinImageView.hidden = NO;

    }];

}else{

    cell.mapPinImageView.hidden = NO;
    [cell.objectImage setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/staticmap?center=%f,%f&zoom=14&size=600x338&maptype=roadmap&sensor=false&key=APIKEY",activity.object.location.coordinate.latitude, activity.object.location.coordinate.longitude]] placeholderImage:nil];

}
