iOS summary _ios7.0 after changing the status bar font face problem

First, add the view controller-based status bar appearance entry in the Info.plist file

If set to Yes, the view controller sets the priority of the status bar higher than the application setting; set to No to the setting of application.

Although 7.0SDK later in the Uiviewcontroller also joined the

-(uistatusbarstyle) Preferredstatusbarstyle Ns_available_ios (7_0); Defaults to Uistatusbarstyledefault

-(BOOL) Prefersstatusbarhiddenns_available_ios(7_0); //Defaults to NO

But I've set the View controller-based status bar appearance to Yes and I've rewritten these methods, and I don't know if I've got something wrong, We have a solution to this.

Ways to change font color:

Set view controller-based status bar appearance to No

Turn White

[[uiapplicationsharedapplication] setstatusbarstyle: Uistatusbarstylelightcontent];

into a black default

[[uiapplication sharedapplication] setstatusbarstyle: Uistatusbarstyledefault];
