如何使用自定义相机视图拍摄照片？
我想在用户在屏幕上标签时立即释放快门。 我有工作代码以全屏模式显示相机。 我怎样才能触摸快门？
- (IBAction) takePicture
{
if (!self.imgPicker) {
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsEditing = NO;
self.imgPicker.delegate = self;
}
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
self.imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.imgPicker.showsCameraControls = NO;
self.imgPicker.wantsFullScreenLayout = YES;
CGAffineTransform cameraTransform = CGAffineTransformMakeScale(1.132, 1.132);
self.imgPicker.cameraViewTransform = cameraTransform;
UIView *headsUpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 480, 320)];
[self.imgPicker setCameraOverlayView:headsUpView];
} else {
NSLog(@"Camera not available.");
self.imgPicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
}
[self presentModalViewController:self.imgPicker animated:YES];
}
您应该使用takePicutre方法，然后检测屏幕上的任何触摸。

像这样的东西
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [[event allTouches] anyObject];
self.imgPicker.takePicture;
}
