IOS modifies app's status bar color to white __ios

After IOS7, the system provides two ways to manage the status bar:

1. Through UIApplication management (the entire application's status bar is managed by it)

2. Through Uiviewcontroller management (each uiviewcontroller can have the unused status bar)

Mode one:

1. Code:

    UIApplication *myapplication = [uiapplication sharedapplication];
    Do not hide
    [MyApplication setstatusbarhidden:no];
    Set to White
    [MyApplication setstatusbarstyle:uistatusbarstylelightcontent Animated:yes];

2. Modify the properties of the Info.plist file: View controller-based status bar appearance = NO (meaning that the status bar is assigned to uiapplication Management) to achieve the entire app as white status bar effect

Mode two:

Individually modify the status bar color inside the Uiviewcontroller

/** Modify the current Uiviewcontroller status bar color is white * * *
-(Uistatusbarstyle) Preferredstatusbarstyle
{return
    uistatusbarstylelightcontent;
}
