我在使用 UIImagePickerController 时遇到问题。基本上，虽然选择器显示良好，但 UIImagePickerController didFinishPickingMediaWithInfo 方法拒绝被调用(我一直尝试 NSLogging，只是没有被调用)。这是我的代码(我已在 header 中将 imgPicker 定义为 UIImagePickerController):
-(IBAction)grabImage {
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsImageEditing = YES;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:self.imgPicker animated:YES];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
imgview.image = [info objectForKey:UIImagePickerControllerEditedImage];
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
}
有人知道为什么它没有被调用吗？
最佳答案
你是否设置了 UIImagePickerController 的 delegate 属性，如果没有设置如下
myImagePickerController.delegate = self;
同时确认 UIImagePickerControllerDelegate 协议(protocol)，
关于iphone - UIImagePickerController didFinishPickingMediaWithInfo 未被调用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5495729/
