Question

我已经实现了一个PickerController让用户选择一个图像，但我希望用户选择的图像显示在我拥有的UIImageView上。

我使用以下内容进入相机胶卷：

- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;

picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

[picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];


[self presentModalViewController: picker animated: YES];


[self presentModalViewController: picker animated: YES];

}

它会调出相机胶卷，用户可以在其中点击照片。但是，点击后，它会返回到主视图，这很明显......但是如何为按钮或用户选择的图像指定动作。像UIOKButton这样的东西？

类似的东西：

if ([UIImagePickerController presentModalViewController:nil image:nil] == UIOKButton ) {

NSArray *images = [UIImagePickerController images];

for(UIImage* pickerImage in [UIImagePickerController images])

{

myUIImage.image setImage pickerImage;
//^in the view

}

我不确定该怎么做。

所有回复都表示赞赏。

谢谢！

Answer 1

- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {

     UIImagePickerController *picker = [[UIImagePickerController alloc] init];
     picker.delegate = self;
     picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

     [picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];

     [self presentModalViewController: picker animated: YES];
}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    // Dismiss the picker
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];

    // Get the image from the result
    UIImage* image = [info valueForKey:@"UIImagePickerControllerOriginalImage"];

    myUIImage.image = image;
}

Answer 2

使用委托方法：– imagePickerController:didFinishPickingMediaWithInfo:。

将图像从相机胶卷设置为UIImageView
