来自 UIImagePicker 的 Iphone 图片不显示

Question

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;
}

但是当调用这个方法时，图像并没有显示在ImageView中。

有什么想法吗？

谢谢

(我已经在单独的 View 中尝试过并且它有效所以我不知道发生了什么)

首先，你首先要关闭你的选择器，你可以尝试:

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

或者你可以试试这个委托(delegate):

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

    NSData *chosenImage = UIImageJPEGRepresentation(image, 1.0);

    yourImage.image = [UIImage imageWithData:chosenImage];

}
