If you pan around the earth, markers disappear #20

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

Pan right around the earth when there's a marker on the map.

What is the expected output? What do you see instead?

Markers disappear. [overlay correctPositionOfAllSublayers] should be called
when the map wraps around.

Hi Joseph,

Can you figure this one out? As a backup I am applying the [overlay
correctPositionOfAllSublayers] but I imagine it is a very expensice operation as
markers increases in number.

Olivier

Multiple issues may be resolved by r231. Please do a checkout of 
/svn/branches/issue63 and test 
against that branch.

The RMProjection does the wrapping, but the contents never check when wrapping 
occurs.

The three move functions in RMMapContents are:

- (void)moveToLatLong: (CLLocationCoordinate2D)latlong
{
    RMXYPoint aPoint = [projection latLongToPoint:latlong];
    [self moveToXYPoint: aPoint];
}
- (void)moveToXYPoint: (RMXYPoint)aPoint
{
    [mercatorToScreenProjection setXYCenter:aPoint];
    [overlay correctPositionOfAllSublayers];
    [tileLoader reload];
    [renderer setNeedsDisplay];
}

- (void)moveBy: (CGSize) delta
{
    [mercatorToScreenProjection moveScreenBy:delta];
    [imagesOnScreen moveBy:delta];
    [tileLoader moveBy:delta];
    [overlay moveBy:delta];
    [renderer setNeedsDisplay];
}

I'm unsure why moveToXYPoint has a correctPositionOfAllSublayers but moveBy 
doesn't.

Incorrect results from RMMercatorToScreenProjection's projectXYPoint:withScale: 
method are the 
root cause of Issue 20, Issue 43, Issue 54, Issue 103.
