iPhone SDK - 如何使用自定义相机视图拍照？

Question

我想在用户点击屏幕时立即释放快门。我有用于以全屏模式显示相机的工作代码。如何通过触摸触发快门？

- (IBAction) 拍照 { 如果（！self.imgPicker）{ self.imgPicker = [[UIImagePickerController alloc] init]; self.imgPicker.allowsEditing = 否； self.imgPicker.delegate = self; } if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { self.imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera; self.imgPicker.showsCameraControls = 否； 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]; } 别的 { NSLog(@"相机不可用。"); self.imgPicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; } [自我presentModalViewController：self.imgPicker动画：YES]； }

您应该使用 takePicutre 方法，然后检测屏幕上的任何触摸。

http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIImagePickerController_Class/UIImagePickerController/UIImagePickerController.html#//apple_ref/occ/instm/UIImagePickerController/takePicture

类似的东西

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