ios - 使用 UIImagePickerController 拍照后将我发送到详细 View

Question

我陷入了以下问题:当我使用 UIImagePickerController 拍照时，我想将用户发送到另一个 View ，其中所选图像可见，并且他/她可以填写更多信息。但是细节 View 没有显示，而不是当我拍照时应用程序挂起，即使照片保存在我的手机上。我能做什么？

我的代码:

@interface PhotoViewController : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate>

@property (nonatomic, strong) UIImagePickerController *imagePicker;
@property (nonatomic, strong) UIImage *image;

@end


#import "PhotoViewController.h"
#import "PostViewController.h"
#import <MobileCoreServices/UTCoreTypes.h>

@implementation PhotoViewController

- (void)viewDidLoad {
    // Do any additional setup after loading the view.
    [super viewDidLoad];
}

-(void) viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    if (self.image == nil) {
        self.imagePicker = [[UIImagePickerController alloc] init];
        self.imagePicker.delegate = self;
        self.imagePicker.allowsEditing = NO;
        self.imagePicker.videoMaximumDuration = 10;

        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
            self.imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        } else {
            self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        }

        self.imagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:self.imagePicker.sourceType];

        [self presentViewController:self.imagePicker animated:YES completion:nil];
    }
}

-(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [self dismissViewControllerAnimated:NO completion:nil];
    [self.tabBarController setSelectedIndex:0];
}

-(void) imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
        // A photo was taken/selected!
        self.image = [info objectForKey:UIImagePickerControllerOriginalImage];
        if (self.imagePicker.sourceType == UIImagePickerControllerSourceTypeCamera) {
            // Save the image!
            UIImageWriteToSavedPhotosAlbum(self.image, nil, nil, nil);
        }
    }
}

我还发布了我的 Storyboard 以澄清问题。

您的屏幕截图太小，无法辨认。发布指向其他网站上的文件的链接。

无论如何，在我看来，问题在于您没有忽略图像选择器。

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


    //--------------------------------------------------
    //This is the line you're missing
    picker.dismissViewControllerAnimated(true, completion: nil)
    //--------------------------------------------------
    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
        // A photo was taken/selected!
        self.image = [info objectForKey:UIImagePickerControllerOriginalImage];
        if (self.imagePicker.sourceType == UIImagePickerControllerSourceTypeCamera) {
            // Save the image!
            UIImageWriteToSavedPhotosAlbum(self.image, nil, nil, nil);
        }
    }
}
