如何使用iphone摄像头拍摄视频

我正在开发一个应用程序。因为我需要用相机拍摄视频。所以请告诉我怎么做。

仔细阅读。它将告诉您如何解决问题。

我假设您知道如何使用

UIImagePickerController

#import <MediaPlayer/MediaPlayer.h> // add MediaPlayer.framework

- (IBAction) startCamera
{
    UIImagePickerController * startCamera;
    startCamera = [[UIImagePickerController alloc] init];
    startCamera.delegate = self;

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) 
    {           
        NSArray *mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
        startCamera.mediaTypes = mediaTypes ;
        startCamera.sourceType = UIImagePickerControllerSourceTypeCamera;
        startCamera.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo ;
        startCamera.allowsEditing = YES ;

    } 
    else
    {
        startCamera.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    }

        [self presentModalViewController:startCamera animated:YES]; 
        [startCamera release];
}

#导入//添加MediaPlayer.framework
-（IBAction）startCamera
{
UIImagePickerController*startCamera；
startCamera=[[UIImagePickerController alloc]init]；
startCamera.delegate=self；
如果（[UIImagePickerController IsSourceType可用：UIImagePickerController SourceType相机]）
{           
NSArray*mediaTypes=[NSArray arrayWithObject:（NSString*）kUTTypeMovie]；
startCamera.mediaTypes=媒体类型；
startCamera.sourceType=UIImagePickerControllerSourceTypeCamera；
startCamera.cameraCaptureMode=UIImagePickerControllerCameraCaptureModeVideo；
startCamera.allowsEditing=是；
} 
其他的
{
startCamera.sourceType=UIImagePickerControllerSourceTypePhotoLibrary；
}
[自我呈现ModalViewController:startCamera动画：是]；
[startCamera发布]；
}

试试这个代码片段。仅在设备中测试此代码。使用UIImagePickerDelegate方法处理录制的视频

UIImagePickerController *picker = [[UIImagePickerController alloc] init]; 
picker.delegate = self; 
picker.allowsEditing = YES;
if (([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])) 
{
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    [self presentModalViewController: picker animated:YES]; 
}
else
{
    NSLog(@"Put alert no camer found");
        // Put alert no camer found
}
[picker release];
