なぜこのエラーが発生し、困惑したのか理解できないようです。

クラスPlaceMarkのインスタンス0x7c763e0は、キー値オブザーバーがまだ登録されている間に割り当てが解除されました。観測情報が漏洩し、他の物体に誤って付着する可能性もあります。NSKVODeallocateBreakにブレークポイントを設定して、デバッガーでここで停止します。現在の観測情報は次のとおりです。<NSKeyValueObservationInfo 0x7c77220> ( <NSKeyValueObservance 0x7c77070: Observer: 0x7ba10c0, Key path: coordinate, Options: <New: NO, Old: NO, Prior: YES> Context: 0x0, Property: 0x7c76b00>)

これが私のviewForAnnotationとCallOutAccessoryです：

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation: (id <MKAnnotation>)annotation {
MKPinAnnotationView *pinView = nil;
if(annotation != mapview.userLocation)
{
    static NSString *defaultPinID = @"pin";
    pinView = (MKPinAnnotationView *)[mapview dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
    if ( pinView == nil ) pinView = [[[MKPinAnnotationView alloc]
                                      initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
    pinView.pinColor = MKPinAnnotationColorGreen;
    pinView.canShowCallout = YES;
    pinView.animatesDrop = YES;
    pinView.rightCalloutAccessoryView = [[UIButton buttonWithType:UIButtonTypeDetailDisclosure] retain];
    pinView.backgroundColor = [UIColor clearColor];


} else {

    CLLocationCoordinate2D userLoc;
    userLoc.latitude = mapview.userLocation.location.coordinate.latitude;
    userLoc.longitude = mapview.userLocation.location.coordinate.longitude;

    int degrees = userLoc.latitude;
    double decimal = fabs(userLoc.latitude - degrees);
    int minutes = decimal * 60;
    double seconds = decimal * 3600 - minutes * 60;
    NSString *lat = [NSString stringWithFormat:@"%d° %d' %1.4f\"", degrees, minutes, seconds];

    degrees = userLoc.longitude;
    decimal = fabs(userLoc.longitude - degrees);
    minutes = decimal * 60;

    NSString *coordinate_l = [NSString stringWithFormat:@"%@ %@ %@",lat,@", ",longt];

    [mapview.userLocation setSubtitle:coordinate_l];
    [mapview.userLocation setTitle:@"Coordinates:"];
}
return pinView;
}

- (void)mapView:(MKMapView *)mapView pinView:(MKAnnotationView *)pinView calloutAccessoryControlTapped:(UIControl *)control {
dViewController = [[detailViewController alloc] initWithNibName:@"detailViewController" bundle:nil];

PlaceMark *theAnnotation = (PlaceMark *) pinView.annotation;

dViewController.descriptiontext = theAnnotation.description;
dViewController.titletext = theAnnotation.title;
dViewController.icontext = theAnnotation.text;

[self presentModalViewController:dViewController animated:true];
[dViewController release];
}

これが私のPlaceMarkクラスです。

@interface PlaceMark : NSObject <MKAnnotation> {
CLLocationCoordinate2D coordinate;

NSString *currentSubTitle;
NSString *currentTitle;
NSString *currentDescription;
NSString *currentText;
}

@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
@property (nonatomic, copy) NSString *currentTitle;
@property (nonatomic, copy) NSString *currentSubTitle;
@property (nonatomic, copy) NSString *currentDescription;
@property (nonatomic, copy) NSString *currentText;

- (NSString *)title;
- (NSString *)subtitle;
- (NSString *)description;
- (NSString *)text;

-(id)initWithCoordinate:(CLLocationCoordinate2D) c;

@end

@implementation PlaceMark
@synthesize coordinate,currentTitle,currentSubTitle,currentDescription,currentText;

- (NSString *)subtitle{
return currentSubTitle;
}
- (NSString *)title{
return currentTitle;
}
- (NSString *)description{
return currentDescription;
}
- (NSString *)text{
return currentText;
}

-(id)initWithCoordinate:(CLLocationCoordinate2D) c{
coordinate=c;
NSLog(@"%f,%f",c.latitude,c.longitude);
return self;
}

- (void)dealloc
{
self.currentDescription=nil;
self.currentText=nil;
self.currentSubTitle=nil;
self.currentTitle=nil;

[super dealloc];
}

@end

注釈のカスタムロード関数：

- (void)loadLeeAnnotations{
//retrieve path of plist file and populate relevant types with its information
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"Coordinates" ofType:@"plist"];
NSDictionary *rootPlistDict = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
NSMutableArray *arboAnnotations = [[NSMutableArray alloc] init];

//NSMutableDictionary *arboDict = [rootPlistDict objectForKey:key];

このエラーは通常、座標が無効であることを意味します。
緯度は-90から90で、経度は-180から180である必要があります。

おそらく、コードは緯度に経度の値を使用しており、その逆もあります（または、plistの値が逆になっている可能性があります）。

私はそれを修正しましたありがとうアンナ！削除に関するコメント

[addAnn release];

カスタムアノテーションの読み込みクラスから、問題が修正されたようです。次に、注釈ポップアップを表示して、クリックできないように見え、クリックしても何もしないことを示す必要があります。
