转场的方法
- push方法转场
- modal方法转场
- 自定义转场
//push方法转场
[self.navigationController pushViewController:[ZCResultViewController new] animated:YES];//push
[self.navigationController popViewControllerAnimated:YES];//返回
//modal方法转场
[self presentViewController:[ZCResultViewController new] animated:YES completion:nil];//present
[self dismissViewControllerAnimated:YES completion:nil];//返回
UIViewController状态
- (void)loadView {
[super loadView];
}
- (void)viewDidLoad {
[super viewDidLoad];
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidDisappear:animated];
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
}
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
注意 : (loadView方法) If you use Interface Builder to create your views and initialize the view controller, you must not override this method.
转场过程对状态的影响
- 从firstVC转场到resultVC的过程，依次调用
- viewWillDisappear（firstVC）
- viewWillAppear （resultVC）
- viewDidDisappear （firstVC）
- viewDidAppear （resultVC）
- 从resultVC转场到firstVC的过程，依次调用
- viewWillDisappear（resultVC）
- viewWillAppear （firstVC）
- viewDidDisappear （resultVC）
- viewDidAppear （firstVC）
说明 : Disappear（Appear）过程无转场动画的情况下，Will和Did方法之间几乎是同时调用。在有转场动画的情况下，Will和Did方法的调用时间相差0.6秒左右
