Question

我正在从像这样的照片库中选择一张图片

 UIImagePickerController *pickerLibrary = [[UIImagePickerController alloc] init];
pickerLibrary.delegate = self;
pickerLibrary.allowsEditing = YES;
pickerLibrary.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:pickerLibrary animated:YES completion:NULL];

并加载图像我这样做

- (void) imagePickerController:(UIImagePickerController *)pickerLibrary didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
{
    NSLog(@"picked image: %@", image);
    self.img = image;
}

会导致以下错误

Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [160 nan]'

我一直在寻找，但找不到任何解决我问题的方法。想法？可能很简单？

Answer 1

好吧，问题似乎是我忘了删除旧的

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

来自我拍摄照片代码的早期版本。现在看起来它正常工作

Answer 2

试试这个

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissViewControllerAnimated:YES completion:^{
    UIImage *image=[info objectForKey:UIImagePickerControllerEditedImage];
    self.img = image;
}];
}

从照片库中挑选的空（零）uiimage
