Question

我有一个应用程序可以加载相机并覆盖按钮以进行点火，重新加载和返回，以及在点击点火和重新加载按钮时动画的png。在相机视图加载时，如何将带有按钮和图像的.xib加载视图控制器作为叠加层？

当点击主屏幕上的按钮时，我会加载摄像机视图，用于打开另一个带有按钮和喷枪图像的视图。

以下是我到目前为止所做的，即加载相机。我有一个名为PlayViewController的独立视图控制器，接口有一个xib：

-(IBAction)getCameraPicture:(id)sender {


UIImagePickerController *picker = [[UIImagePickerController alloc] init];

picker.sourceType = UIImagePickerControllerSourceTypeCamera;

PlayViewController* overlay = [[PlayViewController alloc] initWithNibName:@"PlayViewController" bundle:nil];
picker.cameraOverlayView = overlay.view;
[picker setDelegate:overlay];
[self presentModalViewController:picker animated:YES];

} 这是在PlayViewController.m中：code

   #import "PlayViewController.h"
   #import "SoundViewController.h"

@interface PlayViewController ()

@end

@implementation PlayViewControlleriPad...

`

PlayViewController.h：

@interface PlayViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
{

two array declarations...

}

@property (weak, nonatomic) IBOutlet UIButton *reloadButton;
@property (weak, nonatomic) IBOutlet UIButton *fireButton;
@property (weak, nonatomic) IBOutlet UITextField *ammoField;
@property (weak, nonatomic) IBOutlet UIImageView *type;

@end

Answer 1

像往常一样创建视图控制器和xib，然后将其添加到您的代码中：

YourOverlay* overlay = [[YourOverlay alloc] initWithNibName:@"YourOverlayView" bundle:nil];
picker.cameraOverlayView = overlay.view;
[picker setDelegate:overlay];
[self presentModalViewController:picker animated:YES];

叠加层必须实施UIImagePickerControllerDelegate和UINavigationControllerDelegate

Answer 2

picker.cameraOverlayView = someViewController.view;

使用View Controller作为相机覆盖？
