iphone - 如何捕捉视频

Question

我怎样才能录制视频

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.allowsEditing = YES;
imagePickerController.mediaTypes =  [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
imagePickerController.delegate = self;
[self presentModalViewController:imagePickerController animated:YES];
[imagePickerController release];

我试过这个，但我正在捕捉图像，但我没有捕捉到视频。

Answer 1

#import <MobileCoreServices/UTCoreTypes.h>


-(void)actionStartVideoRecord:(id)sender  {
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
    return;
}
UIImagePickerController* imagePicker = [[[UIImagePickerController alloc] init] autorelease];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.videoQuality = UIImagePickerControllerQualityTypeHigh;
imagePicker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
imagePicker.delegate = self;

[self presentModalViewController:imagePicker animated:YES];
}






- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mType = [info valueForKey:UIImagePickerControllerMediaType];
if([mType isEqualToString:@"public.movie"]){
[NSData dataWithContentsOfURL:[info objectForKey:@"UIImagePickerControllerMediaURL"]]
}
}

出现imagePickerController后，启动设备的 videoCapture。

有关更多信息，请参阅UIImagePickerController的文档

你可以创建一个子类UIImagePickerController。在那里你可以有一个UIButton. 点击它，您可以开始捕捉视频。
