iOS模拟器是否能够模拟设备的相机？

Question

为了确保我拥有正确的所有代码,这是我的头文件:

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UIImagePickerControllerDelegate,UINavigationControllerDelegate> {

    IBOutlet UIImageView *imageView;
    IBOutlet UIButton *choosePhoto;
    IBOutlet UIButton *takePhoto;

}

@property(nonatomic, retain) UIButton *choosePhoto;

@property(nonatomic, retain) UIButton *takePhoto;

@property(nonatomic, retain) UIImageView *imageView;

-(IBAction)getPhoto:(id)sender;
-(IBAction)takePhoto:(id)sender;

@end

然后这是我的实现:

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize imageView,choosePhoto,takePhoto;

- (void)viewDidLoad
{
    [super viewDidLoad];

}

-(IBAction)getPhoto:(id)sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    [self presentViewController:picker animated:YES completion:nil];
}

-(IBAction)takePhoto:(id)sender {

    UIImagePickerController *picker2 = [[UIImagePickerController alloc] init];
    picker2.delegate = self;
    picker2.sourceType = UIImagePickerControllerSourceTypeCamera;
    [self presentViewController:picker2 animated:YES completion:nil];
}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    [picker dismissViewControllerAnimated:YES completion:nil];
    imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
}

-(void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];

}

@end

我的界面构建器中有两个UIButtons和一个UIIImageView.测试应用程序构建正常,没有任何问题,但当我按下选择照片或拍照片按钮应用程序崩溃.这只是因为模拟器技术上没有照片或相机库可供选择吗？这是它给我的错误: UIStatusBarStyleBlackTranslucent在此设备上不可用.

建议非常感谢!

硬件仿真支持

iOS模拟器不模拟加速度计或相机硬件.

此外,H2CO3是正确的,你有一个不同的问题,错误信息非常清楚:

'在iPad上,必须通过UIPopoverController呈现UIIMagePickerController'

快速谷歌搜索指向我下面的链接.查看Zubair的回复.我认为你需要在iPad上运行时在弹出窗口中呈现UIImagePickerController.
