iOS Hidden status bar

It is not easy to operate the top status bar after iOS, the following steps:

First add the View controller-based status bar appearance item in the Info.plist file,

One. The view controller-based status bar appearance item is set to Yes, the view controller has a priority setting of status bar higher than the application setting.

When the view Controller has a priority setting of status bar higher than the application setting, the status bar is hidden in the following way:

1. Call Setneedsstatusbarappearanceupdate in the View controller to update the display of the status bar.

-(void) Viewdidappear: (BOOL) animated{

[Super viewdidappear:animated];

if ([Self respondstoselector: @selector (setneedsstatusbarappearanceupdate)]) {

[Self Prefersstatusbarhidden];

[Self performselector: @selector (setneedsstatusbarappearanceupdate)];

}

}

2. The implementation of the Prefersstatusbarhidden of the view controller will be returned to Yes.

-(BOOL) Prefersstatusbarhidden

{

return YES;

}

Two. If the view controller-based status bar appearance is set to No, the Prefersstatusbarhidden method of the view controller is not valid, whichever is the application setting. is not to be called at all.

1. Use [[UIApplication sharedapplication] Setstatusbarhidden:yes Withanimation:no] to hide the status bar.

Because to be compatible with multiple system versions, I generally use method two
