iOS7 Safari to swipe to the right from the left edge of the screen in the browser's back function is performed.
(Safari screen)

* Knack is screen start swipe from the left side as much as possible.

And the music app, is this well presented at various sites, but in fact this feature Safari as well as standard apps, notes app, select details from the list, are displayed scenes also work.
(If you screen)

In fact this feature is on iOS7 SDK UINavigationController class standard implementation features. So the app in the app was built using the iOS7 SDK, using the Uinavigationhontroller,(Unless you don't change the touch action)Automatically equipped with this feature.
For example, mail app I have patronized "ibisMail" also responded to iOS7 flat GUI image that this app even swipe back feature is enabled.
(ibisMail screen)

It is expected to swipe back features become effective as well as walking Player is currently developing iOS7 flat GUI image-enabled version is.
(Developing Walking Player screen)

Not just now, a little Walking Player version release has been delayed, but simple, iOS7-friendly flat GUI image corresponds to, has carried out some iOS7/iOS6 common user interface improvements. I think there is value in the continued use of the iOS6 to update. Released until now please wait for a while.

It is currently developing a flat Walking Player iOS7 GUI version, in that standard if you bug found, leave together.
If you have any problem in the special conditions, but need help with the strange behavior of this article becomes a reference.

[Problem description]
My music library contains the following BJ Special Track album.

Is that that this album has changed little and other mixed multiple genres in the album. Usually, all songs in the album one of the songs in the same genre. Problems can occur if you like this album in one in multiple genres.
(This album is certainly old, something PCs what app in free as a sample what was going on, maybe quite many people unwittingly may have)

Problem generating operation
After you restart / stop once[Genre]-[Ethnic]And shown in the following screen[BJ Special Track]Ethnic genres in the album said that during[BJ Special-Ethnic-]That song just narrow down the displayed. This is the correct view.("5 songs, one minute" and overlook the playback time song yet song number 5 songs on the entire album is funny and I think, this is not matter, talk of the problem so that the.)

Followed by the[Album]-[BJ Special Track]In the following screen and choose[BJ Special-Ethnic-]Said song only appear, do not appear in other songs.

5 songs from this screen is not focused in the genre of this album, all the songs in the album will become sure don't show everything, and this is.

After the next, again if you stop / restart[Album]-[BJ Special Track]Pick and now displayed 5 songs all are shown in the following screen. Is this the correct view.

However, following the[Genre]-[Ethnic]Will be displayed 5 songs all pick and shown in the following screen without being squeezed in the genre.

Actually this happens the same problem even iOS7 on Walking Player v1.02.(in the iOS6.1 standard if you are Walking Player does not occur this problem.)

[Workaround]
Access to either after you restart the app now correctly displayed.

[Future response plans]
Is the above phenomena were investigated in Walking Player tested to iOS7 music library access API know until that problem because you bug report otherwise Apple will. Just a problem in the special conditions, so may not again soon.
