-(void)Open_Library

imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.delegate=self;
// Delegate is self
// Allow editing of image ?

// Show image picker

CGRect popoverRect = CGRectMake(10, 10, 200, 200);
[popover presentPopoverFromRect:popoverRect inView:self.imgview permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
else
{
[self presentViewController:imagePicker animated:YES completion:nil];
}
}

[picker dismissModalViewControllerAnimated:YES];
}在这里，图像是在画廊打开，但不选择。这里的"imgview“是IMAGEVIEW我为显示从画廊中选择的图像而拍摄的。我在这里做错了什么。我想显示从画廊中选择的图像。
