ios点击按钮隐藏状态栏详解

前言：

最近学习ios的基础知识，实现隐藏状态栏的功能，这里就记录下来，希望对大家有所帮助

实例代码：

@interface secondviewcontroller ()
@property (nonatomic, assign,getter=ishidestatus) bool hidestatus;
@end

@implementation secondviewcontroller

- (void)viewdidload {
  [super viewdidload];
  self.view.backgroundcolor = [uicolor whitecolor];

  uibutton *button = [[uibutton alloc] initwithframe:cgrectmake(0, 0, 300, 200)];
  button.center = self.view.center;
  button.backgroundcolor = [uicolor bluecolor];
  [button settitle:@"隐藏导航栏" forstate:uicontrolstatenormal];
  [button addtarget:self action:@selector(hideframe) forcontrolevents:uicontroleventtouchupinside];
  [self.view addsubview:button];

  self.hidestatus = [uiapplication sharedapplication].statusbarhidden;

  // do any additional setup after loading the view, typically from a nib.
}


- (void)hideframe {

  [self setneedsstatusbarappearanceupdate];//调用该方法后系统会调用prefersstatusbarhidden方法
  self.hidestatus = !self.hidestatus;

}
- (bool)prefersstatusbarhidden
{
  return self.hidestatus;
}
