unity3D用のiOSプラグインを作成しています。以下はコードです。ただし、[regionMonitorstartMonitor]関数がEXC_BAD_EXCESSで呼び出されたときに爆破されます。インターネットの投稿によると、メモリ管理エラーのようです。誰もがここで問題が何であるかを見ることができますか？ありがとう。

「RegionMonitoringPlugin.h」

 #import <Foundation/Foundation.h>
 #import <CoreLocation/CoreLocation.h>


@interface RegionMonitoringPlugin : NSObject <CLLocationManagerDelegate>
{
    CLLocationManager *locationManager; 
}

-(void)leavingHomeNotify;
-(void)startMonitor:(float)latitude longitude:(float)longitude radius:(float)raduis;

@end

「RegionMonitoringPlugin.mm」

#import "RegionMonitoringPlugin.h"

@implementation RegionMonitoringPlugin

- (id) init
{
    if (self = [super init])
   {
      locationManager = [[[CLLocationManager alloc] init] autorelease];
      locationManager.delegate = self;
      [locationManager setDistanceFilter:kCLDistanceFilterNone];
      [locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
   }
return self;
}

-(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region
{
    [self leavingHomeNotify];
}

-(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region
{
    [self leavingHomeNotify];
}

 - (void)locationManager:(CLLocationManager *)manager monitoringDidFailForRegion:(CLRegion *)regionwithError:(NSError *)error
{
    NSLog(@"Location error %@, %@", error, @"Fill in the reason here");
}

-(void)leavingHomeNotify
{
UILocalNotification *note = [[UILocalNotification alloc] init];
note.alertBody= @"Region Left";
[[UIApplication sharedApplication] presentLocalNotificationNow:note];
[note release];
 }

 -(void)startMonitor:(float)latitude longitude:(float)longitude radius:(float)radius
 {
  CLLocationCoordinate2D home;
  home.latitude = latitude;
  home.longitude = longitude;
  CLRegion* region = [[CLRegion alloc] initCircularRegionWithCenter:home radius:radius identifier:@"home"];
  [locationManager startMonitoringForRegion:region desiredAccuracy:kCLLocationAccuracyBest];
  [region release];    
 }

@end

extern "C" {

    static RegionMonitoringPlugin *regionMonitor;

    // Unity callable function to start region monitoring
    BOOL _startRegionMonitoring(float m_latitude,float m_longitude, float m_radius)
    {
        if (![CLLocationManager regionMonitoringAvailable] || ![CLLocationManager regionMonitoringEnabled] )
            return NO;
        if (regionMonitor == nil){
            regionMonitor = [[[RegionMonitoringPlugin alloc]init ] autorelease];
        }
        [regionMonitor startMonitor:m_latitude longitude:m_longitude radius:m_radius];
        return YES;

    }
}

私がそれを正しく見れば、あなたはすべきではなくautorelease locationManager、どちらでもありませんregionMonitor。

代わりにdeallocメソッドを追加してください。位置監視を停止したら、を解放する必要がありますrelease locationManager。regionMonitor
