Question

我在侧边栏中使用SWRealViewController。我的moviePlayer工作正常，全屏，但当我点击全屏moviePlayer崩溃，我得到一个错误：

2014-01-01 19：23：00.860 Chingfong [56193：70b]警告：尝试从视图控制器中解雇正在进行陈述或解雇！

这是我在movieVC.h中的代码

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

@interface movieVC : UIViewController
{
    NSString *link;
}

@property(nonatomic,retain) NSString *link;
@property(nonatomic, strong)UIActivityIndicatorView *activityIndicator;
@property (strong, nonatomic) MPMoviePlayerController *moviePlayer;

@end

这里是movieVC.m

#import "movieVC.h"
#import "SWRevealViewController.h"
#import <MediaPlayer/MediaPlayer.h>

@interface movieVC ()

@end

@implementation movieVC
@synthesize link;
@synthesize activityIndicator;
