iOS开发应用 录像录音实例

iOS开发应用 录像录音实例是本文要介绍的内容。这段利用苹果自带相机进行录像的代码由 CocoaChina 会员 “1056975026” 分享，对开发的应用中用到拍照、摄像功能的开发者应该有所帮助。

(void) choosePhotoBySourceType: (UIImagePickerControllerCameraCaptureMode) sourceType    
{    
    m_imagePickerController = [[[UIImagePickerController alloc] init] autorelease];    
    m_imagePickerController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;    
    m_imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;    
    m_imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceFront;    
    //m_imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;     
        
        
    NSArray *sourceTypes = [UIImagePickerController availableMediaTypesForSourceType:m_imagePickerController.sourceType];    
    if ([sourceTypes containsObject:(NSString *)kUTTypeMovie ])    
    {    
        m_imagePickerController.mediaTypes= [NSArray arrayWithObjects:(NSString *)kUTTypeMovie,(NSString *)kUTTypeImage,nil];    
    }        
        
        
   // m_imagePickerController.cameraCaptureMode = sourceType;     
    //m_imagePickerController.mediaTypes     
    //imagePickerController.allowsEditing = YES;     
        
    [self presentModalViewController: m_imagePickerController animated:YES];    
}    
-(void) takePhoto    
{    
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])     
    {    
                
            
        [self choosePhotoBySourceType:nil];    
    }    
}    
    
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.     
- (void)viewDidLoad {    
    [super viewDidLoad];    
        
    UIButton *takePhoto = [UIButton buttonWithType:UIButtonTypeRoundedRect];    
    [takePhoto setTitle:@"录像" forState:UIControlStateNormal];    
    [takePhoto addTarget:self action:@selector(takePhoto) forControlEvents:UIControlEventTouchUpInside];    
    takePhoto.frame = CGRectMake(50,100,100,30);    
    [self.view addSubview:takePhoto];
