iOS 11打开系统相册列表向上偏移问题

问题如图



该问题是因为设置了

if (@available(iOS 11, *)) {
UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
}

引起的。

解决方案

在弹出系统相册前加入

if (@available(iOS 11, *)) {
UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentAutomatic;
}

UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
ipc.delegate = self;
ipc.allowsEditing = YES;
if (@available(iOS 11, *)) {
UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentAutomatic;
}
[self presentViewController:ipc animated:YES completion:nil];

在 - (void)imagePickerController:(UIImagePickerController )picker didFinishPickingMediaWithInfo:(NSDictionary

if (@available(iOS 11, *)) {
UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
}

就解决了！！！
