Question

这是我的代码  if（[UIImagePickerController isSourceTypeAvailable：UIImagePickerControllerSourceTypeCamera]）     {         UIImagePickerController * imagePicker = [[UIImagePickerController alloc] init];

    imagePicker.delegate = self;
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
    imagePicker.allowsEditing = NO;
[self presentViewController:imagePicker animated:YES completion:nil];
