我有一个应用程序可以加载相机并覆盖用于触发、重新加载和返回的按钮，以及一个在点击触发和重新加载按钮时动画的 png。当相机视图加载时，我将如何加载具有按钮和图像的 .xib 的视图控制器作为覆盖？

当点击主屏幕上的按钮时，我会加载相机视图，该按钮用于打开带有按钮和枪图像的另一个视图。

以下是我到目前为止所做的，正在加载相机。我有一个名为 PlayViewController 的单独视图控制器，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

像往常一样创建您的视图控制器和 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];

覆盖必须实现UIImagePickerControllerDelegate和UINavigationControllerDelegate
