Problem Description:

In case of a situation, on a controller (hide the navigation bar), after opening the photo selector Uiimagepickercontroller, the photo selector head Blank, and slide album, the information will have a confusion effect.

Cause Analysis:

By looking at the hierarchy, you can see that the navigation bar is actually there, so the problem is that the navigation bar is transparent.

Workaround:

uiimagepickercontroller *picker = [[uiimagepickercontroller alloc] init];

Picker. delegate = self;

Picker. sourcetype = uiimagepickercontrollersourcetypephotolibrary;

[uiapplication sharedapplication].   Statusbarstyle = Uistatusbarstyledefault; This sentence to see personal needs, I need to change the status bar color

Picker. Navigationbar.   Translucent = NO;  This sentence sets the navigation bar opaque (!!!!!!!!!!!!!!!!!!!!!!!!! Solve the problem)

[Picker.    navigationbar setbartintcolor: [uicolor redcolor]]; If you need to set the background color of the custom navigation bar, use this setting

Please leave a message if you have questions.
