Using the Google Maps for iOS SDK, the \"My Location\" button is by default placed in the bottom right hand corner:
The easiest way to solve this is to change the frame and autoresizing mask of the button right after the map view is created.
UIButton* myLocationButton = (UIButton*)[[mapView_ subviews] lastObject];
myLocationButton.autoresizingMask = UIViewAutoresizingFlexibleRightMargin|UIViewAutoresizingFlexibleTopMargin;
CGRect frame = myLocationButton.frame;
frame.origin.x = 5;
myLocationButton.frame = frame;
EDIT: Sorry, I placed the button in the top right corner. Updated my code to place it in the bottom left hand corner.
Note: there is currently no API from Google to get the location button. The first line may not work in future releases of the SDK.
You also should create a feature request here.
Another option is to create the button yourself and add it as a subview to the map. The button handler code is fairly easy:
CLLocation *location = mapView_.myLocation;
if (location) {
[mapView_ animateToLocation:location.coordinate];
}
