。
因此,当我按下拍摄按钮时,它正在拍照并且我可以将图像保存在相机胶卷中。但是当我想在另一个视图中看到图像时,我看不到它。
这是我的代码:
UIViewController
这是对segue方法的准备。
- (IBAction)captureButton:(id)sender
{
[self.cameraViewController captureImageWithCompletionHander:^(id data) {
self.image = ([data isKindOfClass:[NSData class]]) ? [UIImage imageWithData:data] : data;
UIImageWriteToSavedPhotosAlbum(self.image, nil, nil, nil);
[self performSegueWithIdentifier:@"savingSegue" sender:self];
}];
}
答案 0 :(得分:2)
如果您的第二个视图是prepareForSeque
,请将- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"savingSegue"]) {
PhotoSaveViewController *pvc = (PhotoSaveViewController *)segue.destinationViewController;
if (pvc)
[pvc.imageView setImage:self.image];
}
}
方法替换为:
UIViewController
事实上,实例化目的地UINavigationController
不是你的工作,你的/// <reference path="../../../typings/tsd.d.ts" />
import {Mediator} from '../../../services/remoting/Mediator';
describe('Mediator', () =>
{
let mediator: Mediator;
beforeEach(() =>
{
mediator = new Mediator();
});
it('blah blah', () =>
{
expect(mediator.TEST).toBeDefined();
});
});
已经做到了。

我猜imageView
PhotoSaveViewController
@property (nonatomic, retain) UIImage *inputImage;
它是出口而且此刻未设置。你应该声明一些其他属性,如
prepareForSegue
并指定- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"savingSegue"]) {
PhotoSaveViewController *pvc = segue.destinationViewController;
pvc.inputImage = self.image;
}
}
中的内容:
PhotoSaveViewController
然后在- (void)viewDidLoad {
[super viewDidLoad];
self.imageView.image = self.inputImage;
}
:
Storyboard ID
您可以完全从代码创建它的另一种方法。将PhotoSaveViewController
分配给- (IBAction)captureButton:(id)sender {
[self.cameraViewController captureImageWithCompletionHander:^(id data) {
self.image = ([data isKindOfClass:[NSData class]]) ? [UIImage imageWithData:data] : data;
UIImageWriteToSavedPhotosAlbum(self.image, nil, nil, nil);
PhotoSaveViewController *dvc = [self.storyboard instantiateViewControllerWithIdentifier:@"PhotoSaveViewControllerID"];
dvc.inputImage = self.image;
[self.navigationController pushViewController:dvc animated:YES];
}];
}
,然后执行以下操作:
