为了确保所有代码都正确,下面是我的头文件:
#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
下面是我的实现:
#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
。测试应用程序构建良好,没有任何问题,但当我按下选择照片或拍照按钮时,应用程序崩溃。这仅仅是因为模拟器在技术上没有相机或照片库可供选择吗?这是它给我的错误:UIStatusBarStyleBlackTranslucent
在这个设备上不可用。

非常感谢您的建议!

硬件模拟支持
iOS模拟器不模拟加速度计或相机硬件。
此外,H2CO3是对的,你有一个不同的问题,错误消息非常清楚:
‘在iPad上,UIIMagePickerController必须通过UIPopoverController呈现’
我在谷歌上快速搜索一下,找到了下面的链接。看看Zubair对此的回应。我认为当在iPad上运行时,你需要在弹出窗口中显示UIImagePickerController。
UIStatusBarStyleBlackTranslucent is not available on this device

没有模拟器不支持模拟摄像头。对于相机,你必须在设备上运行应用程序
