利用苹果自带相机进行录像的代码

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];

}
