我的 iPhone 应用程序由于僵尸或内存泄漏而崩溃。我已将其缩小到 3 行代码,并且可以通过注释/取消注释代码可靠地实现这两件事之一。当在结果列表(tableView)和包含地图和一些标签的详细信息页面之间导航时会出现错误,当我第一次从地图导航回结果列表时发生内存泄漏,僵尸可能在 5/ 之后发生6 次导航到不同的结果并返回。

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

#define METERS_PER_MILE 1609.344

@interface ResDetailsPageVC : UIViewController <MKMapViewDelegate, UIAlertViewDelegate>  {

UISegmentedControl *mapTypeSwitcher;
MKMapView *mapView;      

UILabel *nameLabel;
UIButton *addressLabel;
UILabel *telephoneLabel;

NSString *address;

}

@property (nonatomic, retain) IBOutlet UISegmentedControl *mapTypeSwitcher;
@property (nonatomic, retain) IBOutlet MKMapView *mapView;

@property (nonatomic, retain) IBOutlet UILabel *nameLabel;
@property (nonatomic, retain) IBOutlet UIButton *addressLabel;
@property (nonatomic, retain) IBOutlet UILabel *telephoneLabel;


- (IBAction)segmentedControlIndexChanged;
- (IBAction)callButtonClick;
- (IBAction)addressClick;

- (void) callNumber;

@end






@synthesize mapView;
@synthesize mapTypeSwitcher;

@synthesize nameLabel, addressLabel, telephoneLabel;

- (void)dealloc {

// if these lines are commented out - memory leak
// if not - zombie?!
/*self.telephoneLabel = nil;
self.addressLabel = nil;
self.nameLabel = nil;*/
self.mapView = nil;
self.mapTypeSwitcher = nil;

[super dealloc];

}

某处其他一些代码正在使用相同的对象,其地址存储在这三个属性之一中,但其他代码没有正确保留该对象。

我向你推荐这个:

- (void)dealloc {
[telephoneLabel release]; telephoneLabel = nil;
[addressLabel release]; addressLabel = nil;
....

[super dealloc];
}
