iPhone代码泄漏,我不知道为什么

Question

这是一个众所周知的片段,如何从iPhone照片库中选择一张图片:

- (IBAction)selectExistingPicture {
  if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    [self presentModalViewController:picker animated:YES];
            [picker release];

  }
}

在这里,您可以看到仪器的屏幕截图(全屏).

它为什么泄漏？我不明白,因为选择器被正确释放,我想.

Answer 1

的UIImagePickerController是公知的泄漏.如果您打算多次使用它,建议您重复使用单个实例
