Upadated: with leaks problems
I am also checking the possibility with memory leaks and using instrument tool I am getting 100% leaks at the time of launching the application. Its NSPlaceholderString leaks on following code...
CLLocationCoordinate2D location;
NSString *url = [NSString stringWithFormat:#"..myurl......lat=%f&lng=%f&radius=5",locationManager.location.coordinate.latitude,locationManager.location.coordinate.longitude];
radiusinurl.text = #"5km";
NSURL *URL = [NSURL URLWithString:url];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:URL];
//Initialize the delegate.
**XMLParser *parser = [[XMLParser alloc] initXMLParser];** //5.3% leaks
//Set delegate
[xmlParser setDelegate:parser];
//Start parsing the XML file.
**BOOL success = [xmlParser parse];** //0.2% leaks
[xmlParser release];
[parser release];
if(success)
{
NSLog(#"show me [appDelegate.markers count] %d",[appDelegate.markers count]);
annobjs = [[NSMutableArray array] retain];
if([appDelegate.markers count] == 0)
{ //99% leaks on below line where I am calling another method
**[self performSelector:#selector(showingThreeResultsOnCurrentLocation) withObject:nil];** //99% leaks
}
else
{//some logic
}
}
else
{
//logic
}}}}
I have commented leaks at the end of line. Can you correct my code. Thanks in advance...

Initialize view controller first
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; //This is for autoresize when in phone call mode(which does not work yet)
[dict setObject:#"trigger" forKey:#"frame"];
[[NSNotificationCenter defaultCenter] postNotificationName:#"trigger"
object:self
userInfo:dict];
arrayNo = [[NSMutableArray alloc] init]; //pickerview radius array
[arrayNo addObject:#"5km"];
[arrayNo addObject:#"10km"];
[arrayNo addObject:#"15km"];
viewController = [[UIViewController alloc] initWithNibName:#"UIViewController" bundle:nil];
UINavigationController *nav = [[UINavigaitonController alloc] initWithRootViewController:nav];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
return YES;
}
