RMMapView setCenterCoordinate function is not normally - iphone

I want to set center of RMMapView with position that's _tempCoordinated2D (CLLocationCoordinate2D)
Normally, It should be
// _rmMapView is RMMapView Class
[_rmMapView setCenterCoordinate:_tempCoordinated2D];
// I try [_rmMapView setCenterCoordinate:_tempCoordinated2D animated:YES];
// I try [_rmMapView setCenterCoordinate:_tempCoordinated2D animated:NO];
Result's wrong.
Because Center of the rmMapView move to _tempCoordinated2D and move back to Current Location.
I have checked my code. It doesn't have a code that's setCenterCoordinate to Current Location.
The problem is not just that.
BUT This's a problem hasn't occurred ,
If I touch the map and move map before run statement setCenterCoordinate of RMMapView.
I don't know why.
Sorry for my bad English.

Do you have a userTrackingMode set on the RMMapView that is causing it to center on the user? Try setting that to RMUserTrackingModeNone.

userLocation.coordinate gave me wrong value

when i try to get the current location using
CLLocationCoordinate2D CurrentLocation;
CurrentLocation = map.userLocation.coordinate;
i get the follwoing values:
CurrentLocation.latitude= -180.000000;
CurrentLocation.longitude= -180.000000;
and it is not my location at all.
do you know what is missing in this?
Firstly, make sure that you have set the mapView's showUserLocation to TRUE.
Secondly, check that the value is not nil, as the mapView needs to locate the user first, and that takes a few seconds.

FlowCoverView How to force the view to move to a given image programmatically?

I'm using FlowCoverView, an open source (and AppStore compliant) alternative to Apple's cover flow (you can find it here http://chaosinmotion.com/flowcover.m)
I'd like to modify the code so that you can force the view to start from (or to move to) a specific image programmatically, given its index.
I'm not being successful though :(
Solution:
-(void)goToIndex:(NSUInteger)index
{
if (index<[self numTiles])
{
offset = index;
[self draw];
//[delegate flowCover:self highlighted:index];
}
}
Set the mid image in draw method in flowcover class.

Simulate mouse on Mac

I have a virtual trackpad on my iPhone and to move my mouse I'm using :
CGDisplayMoveCursorToPoint(kCGDirectMainDisplay, CGPointMake(((float)aD.msg)+location.x, ((float)aD.msg2)+location.y));
It's working well but this not a real mouse because when I put my mouse on my hidden dock, this one doesn't display it self. I don't understand why.
More over I tried to simulate mouse click with :
case MOUSECLICK:
[self postMouseEventWithButton:0 withType:kCGEventLeftMouseDown andPoint:CGEventGetLocation(CGEventCreate(NULL))];
[self postMouseEventWithButton:0 withType:kCGEventLeftMouseUp andPoint:CGEventGetLocation(CGEventCreate(NULL))];
// *********************
-(void)postMouseEventWithButton:(CGMouseButton)b withType:(CGEventType)t andPoint:(CGPoint)p
{
CGEventRef theEvent = CGEventCreateMouseEvent(NULL, t, p, b);
CGEventSetType(theEvent, t);
CGEventPost(kCGHIDEventTap, theEvent);
CFRelease(theEvent);
}
Is it the good method? Thanks for your help !
CGDisplayMoveCursorToPoint() only moves the image of the cursor, it does not generate any events. You should create and post mouse events of type kCGEventMouseMoved to simulate moving the mouse. Your own method would do it:
[self postMouseEventWithButton:0 withType:kCGEventMouseMoved andPoint:point];
For clicks, you are already doing it the right way, I think. One thing you should also do is set the click count properly on both the mouse down and mouse up events, like so:
CGEventSetIntegerValueField(event, kCGMouseEventClickState, 1);
... because some applications need it.
(See also Simulating mouse clicks on Mac OS X does not work for some applications)
If your code doesn't work, I'm not sure why; it looks OK to me. Try posting to kCGSessionEventTap instead of kCGHIDEventTap and see if it helps. Also, you don't need the CGEventSetType() call since the type is already set in the creation call.

How to simulate a user driving a route in a MKMapView?

I need to simulate how my application will look when a user is driving around for a demo. I have a MKMapView, how can I simulate the look of a user driving around which will use the map.userLocation functionality, which obviously will not be available in the demo.
Thanks!
No way to simulate in iPhone simulator. You'll need to load it onto your device and move around.
Well I got something going, I just did essentially this
- (void)moveIcon:(MKAnnotationView*)locationView toLocation:(CLLocation*)newLoc
{
LocationAnnotation* annotation = [[[LocationAnnotation alloc] initWithCoordinate:newLoc.coordinate] autorelease];
[locationView setAnnotation:annotation];
[map setCenterCoordinate:newLoc.coordinate animated:YES];
}
Then I call this guy in a loop between all of my vertices with a slight delay. Works quite qell.
I'm not an iPhone dev expert, but how does the map view receive the coordinates? If it's through a function that calls the CoreLocation API, could you possibly just write a function that randomly generates longitude and latitude values at a certain time interval and have your map view pull the coordinates from there instead? Just a thought.
You could also check out iSimulate which claims to be able to simulate several features only available on the iPhone in the iPhone simulator include CoreLocation. I have not tried this myself so your mileage may vary.
In order to simulate driving you'll need to establish 2 basic functionalities:
Reading CLLocations from an archive (which you'd log during the drive test with a device). Ideally you'll do this based on the timestamps on the locations, i.e. reproducing the exact same location updates which were received during the drive test.
Updating your MKAnnotationView's position on the map based on the locations read from log.
For part 1, take a look at CLLocationDispatch, a handy class which provides archiving/unarchiving of CLLocations and dispatches them to one or more listeners (using CLLocationManagerDelegate protocol).
For part 2, take a look at Moving-MKAnnotationView.
I found a better way would be to subclass MKUserLocation:
class SimulatedUserLocation: MKUserLocation {
private var simulatedCoordinate = CLLocationCoordinate2D(latitude: 39, longitude: -76)
override dynamic var coordinate: CLLocationCoordinate2D {
get {
return simulatedCoordinate
}
set {
simulatedCoordinate = newValue
}
}
}
Then add it as an annotation mapView.addAnnotation(SimulatedUserLocation()). (You might also want to hide the real location first mapView.showsUserLocation = false)
iOS would render the annotation exactly like the real user location.
dynamic is used on the property so that changing coordinate triggers KVO and moves it on the map.
The answer is NO. Then, how about adding an abstraction layer between your code and MKMapKit? You can do xUnit tests for your objective.

Heeelp! Debugger says "out of scope"!

I just cannot imagine what the hell the problem could be.
I made a pretty app, and decided to use only CALayers to "render".
When I saw that the changes in the position property gets animated, decided to implement a custom getter-setter "abstract" property called tanCenter to set the position without animating.
-(void) setTanCenter: (CGPoint) sentCenter
{
//Remove any transactions.
[CATransaction begin];
[CATransaction setValue:(id)kCFBooleanTrue forKey:kCATransactionDisableActions];
//Set position.
self.position = sentCenter;
[CATransaction commit];
//Set value.
tanCenter = sentCenter;
}
-(CGPoint) tanCenter { return tanCenter; }
Since I merged this into the project, it crashes without any "understandable" (for me) error message. I can see only those "out of scope"-s. I cant even get this tanCenter property NSLog-ged without crash.
Help me, Obi-Wan Kenobi; you're my only hope.
If you run in the debugger (Command-Y) and make sure you have global breakpoints enabled, the debugger should stop at the place where the crash occurred giving you an idea of what is nil or over-released.
hey I had the same problem till now. Finally I have found my bug after investigating 2 weeks of bug tracking (it really sucks)
maybe my problem helps you:
I started with a TableView that opens on click another view. So I created in:
-(void)tableView:didSelectRowAtIndexPath:
first the controller for the other view and set the value for a global variable:
SomeView *dtview = [[SomeView alloc] initWithNibName:#"SomeView" bundle:nil];
dtview.lblTitle = cl.textLabel.text; // cl is the cell
[self presentModalViewController:dtview animated:NO];
[dtview release];
So opened the other view and done much functions with much memory usage :)
When I after that close the other view and go back to the table and scroll some times the App terminates with the message "out of scope"
I searched really, really long to find out what was the effect. It seems that when the other view is released also the text of the first table is released.
After putting a copy to the call it worked for me:
dtview.lblTitle = [cl.textLabel.text copy];
For int and bool the first solutions works fine, because these aren't objects but for NSObject's you should copy the values to another view.
