调用系统UIImagePickerController相册时候出现UIImagePickerController Frame不对的问题如图所示。

没有适配IOS11效果[图片上传中)]

我们怎么解决Frame不对导致系统UIImagePickerController被导航栏遮挡的问题呢？

第一步

我们需要在进入到UIImagePickerController

/*适配ios11 导航栏*/
        UIImagePickerController *pc = [[UIImagePickerController alloc]init];
        pc.delegate = self;
        [pc setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
        [pc setModalPresentationStyle:UIModalPresentationFullScreen];
        [pc setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
        /*适配ios11 导航栏*/
        if (@available(iOS 11, *)) {
            UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentAutomatic;
        }
        [pc setAllowsEditing:YES];
        [self presentViewController:pc animated:YES completion:nil];

第二步我们需要在退出UIImagePickerController时候填写

/*UIImagePickerController 解决导航栏问题*/
    if (@available(iOS 11, *)) {
        [UIScrollView appearance].contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever; //iOS11 解决SafeArea的问题，同时能解决pop时上级页面scrollView抖动的问题
    }

适配IOS11效果

希望能帮到您～
