viewController的生命周期

代码写下A、B控制器的打印事件

A的打印事件

- (void)viewDidLoad {

    [super viewDidLoad];

    NSLog(@"viewDidLoad");

}

+ (void)initialize{

    [super initialize];

    NSLog(@"initialize");

}

- (instancetype)init{

   self= [superinit];

    if(self) {

        NSLog(@"init");

    }

    return self;

}

- (void)loadView{

    [super loadView];

    NSLog(@"loadView");

}

- (void)viewWillAppear:(BOOL)animated{

    [superviewWillAppear:animated];

    NSLog(@"viewWillAppear");

}

- (void)viewWillLayoutSubviews{

    [super viewWillLayoutSubviews];

    NSLog(@"viewWillLayoutSubviews");

}

- (void)viewDidLayoutSubviews{

    [super viewDidLayoutSubviews];

    NSLog(@"viewDidLayoutSubviews");

}

- (void)viewDidAppear:(BOOL)animated{

    [superviewDidAppear:animated];

    NSLog(@"viewDidAppear");

}

-(void)viewWillDisappear:(BOOL)animated{

    [super viewWillDisappear:animated];

    NSLog(@"viewWillDisappear");

}

- (void)viewDidDisappear:(BOOL)animated{

    [superviewDidDisappear:animated];

    NSLog(@"viewDidDisappear");

}

- (void)dealloc{

    NSLog(@"dealloc");

}

B的打印事件

- (void)viewDidLoad {

    [super viewDidLoad];

    NSLog(@"viewDidLoad1");

  }

+ (void)initialize{

    [super initialize];

    NSLog(@"initialize1");

}

- (instancetype)init{

   self= [superinit];

    if(self) {

        NSLog(@"init1");

    }

    return self;

}

- (void)loadView{

    [super loadView];

    NSLog(@"loadView1");

}

- (void)viewWillAppear:(BOOL)animated{

    [superviewWillAppear:animated];

    NSLog(@"viewWillAppear1");

}

- (void)viewWillLayoutSubviews{

    [super viewWillLayoutSubviews];

    NSLog(@"viewWillLayoutSubviews1");

}

- (void)viewDidLayoutSubviews{

    [super viewDidLayoutSubviews];

    NSLog(@"viewDidLayoutSubviews1");

}

- (void)viewDidAppear:(BOOL)animated{

    [superviewDidAppear:animated];

    NSLog(@"viewDidAppear1");

}

-(void)viewWillDisappear:(BOOL)animated{

    [super viewWillDisappear:animated];

    NSLog(@"viewWillDisappear1");

}

- (void)viewDidDisappear:(BOOL)animated{

    [superviewDidDisappear:animated];

    NSLog(@"viewDidDisappear1");

}

- (void)dealloc{

    NSLog(@"dealloc1");

}
