UIImagePicker 中的 iPhone 图像不显示

发布于 2024-10-09 15:40:13 字数 546 浏览 0 评论 0原文

我有一个 TabBarController，其中一个选项卡有一个 ImageView。此外，我有一个按钮来显示 ImagePicker 和以下代码：

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

    [self dismissModalViewControllerAnimated:YES];
    [picker release];
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    imageView.image = image;
}

但是当调用此方法时，图像不会显示在 ImageView 中。

有什么想法吗？

谢谢

（我已经在单独的视图中尝试过了，它有效，所以我不知道发生了什么）

i have a TabBarController in which one tab has an ImageView. Besides, i have a button to display the ImagePicker and the following code:

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

    [self dismissModalViewControllerAnimated:YES];
    [picker release];
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    imageView.image = image;
}

But the image doesn't show in the ImageView when this method is called.

Any idea?

Thanks

(I have tried in a separately view and it works so i don't know what is happening)

首先，你首先要解雇你的选择器，你可以尝试：

UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
[self dismissModalViewControllerAnimated:YES];

或者你可以尝试这个委托：

-(void)imagePickerController:(UIImagePickerController *)picker 
       didFinishPickingImage:(UIImage *)image 
                 editingInfo:(NSDictionary *)editingInfo {

    NSData *chosenImage = UIImageJPEGRepresentation(image, 1.0);

    yourImage.image = [UIImage imageWithData:chosenImage];

}

First of all, you are dismissing your picker first thing, you can try:

UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
[self dismissModalViewControllerAnimated:YES];

or you can try this delegate:

-(void)imagePickerController:(UIImagePickerController *)picker 
       didFinishPickingImage:(UIImage *)image 
                 editingInfo:(NSDictionary *)editingInfo {

    NSData *chosenImage = UIImageJPEGRepresentation(image, 1.0);

    yourImage.image = [UIImage imageWithData:chosenImage];

}
