在控制器中加上这段话就好了。
- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
if ([UIDevice currentDevice].systemVersion.floatValue < 11) {
return;
}
if ([viewController isKindOfClass:NSClassFromString(@"PUPhotoPickerHostViewController")]) {
[viewController.view.subviews enumerateObjectsUsingBlock:^(__kindof UIView * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
if (obj.frame.size.width < 42) {
[viewController.view sendSubviewToBack:obj];
*stop = YES;
}
}];
}
}
