我正在創建一個iPad應用程序,我想打開媒體播放器播放視頻。爲此,我在ViewDidLoad()方法中創建一個按鈕。貝婁是我的代碼。視頻播放器給出錯誤(EXC_BAD_ACCESS)
- (void)viewDidLoad
{
[super viewDidLoad]
self.view.backgroundColor = [[[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"1.png"]] autorelease];
m_btn2000 = [[UIButton buttonWithType:UIButtonTypeCustom] autorelease];
m_btn2000.frame = CGRectMake(180, 330, 130, 200);
[m_btn2000 setImage:[UIImage imageNamed:@"2.png"] forState:UIControlStateNormal];
m_btn2000.clipsToBounds = YES;
[m_btn2000 addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:m_btn2000];
}
貝婁是我的按鈕點擊方法代碼:
- (void)btnClicked:(id)sender
{
NSString *filePath1 = [[NSBundle mainBundle] pathForResource:@"test_video" ofType:@"m4v"];
NSURL *fileURL = [NSURL fileURLWithPath:filePath1];
m_moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
m_moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
[m_moviePlayer.view setFrame:CGRectMake(0, 0, 1026, 748)];
[self.view addSubview:m_moviePlayer.view];
[m_moviePlayer play];
}
當我要去點擊按鈕,它給了我EXC_BAD_ACCESS錯誤。 但我注意到一件事,當我把上面的整個代碼按鈕點擊方法放在ViewDidLoad()方法它播放適當的方式播放視頻。
最好的之一......解決。你能否就此簡單闡述一下? – 2012-04-10 11:10:21
+1,它(按鈕對象)已經由工廠方法autoreleased了。 – Ilanchezhian 2012-04-10 11:11:35
