导航控制器用来管理一组具有层级关系的视图控制器,进入下一个界面的方式是push,返回是pop. (层级关系:后一个界面显示的内容依赖于前一个界面)
当没有层级关系的视图控制器之间切换时(比如:前一个界面显示的内容依赖于后一个界面).要使用模态视图,进入下一个界面的方式是present,返回是dismiss.
模态视图:
- (IBAction)pressButton:(UIButton *)btn
{
FirstDetailViewController *firstDetailVC = [[FirstDetailViewController alloc] init];
firstDetailVC.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:firstDetailVC animated:YES completion:^{
NSLog(@"Tsummer");
}];
}
- (IBAction)pressDetailButton:(UIButton *)sender
{
[self dismissViewControllerAnimated:YES completion:^{
NSLog(@"Tsummer");
}];
}
系统提供的页面切换的效果:
typedef NS_ENUM(NSInteger, UIModalTransitionStyle) {
UIModalTransitionStyleCoverVertical = 0, //从底部划入
UIModalTransitionStyleFlipHorizontal, //水平翻转
UIModalTransitionStyleCrossDissolve, //交叉溶解
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_3_2
UIModalTransitionStylePartialCurl, //翻页效果
#endif
};
push推出
- (IBAction)pressButton:(UIButton *)btn
{
FirstDetailViewController *firstDetailVC = [[FirstDetailViewController alloc] init];
[self.navigationController pushViewController:firstDetailVC animated:YES];
}
- (IBAction)pressDetailButton:(UIButton *)sender
{
[self.navigationController popViewControllerAnimated:YES];//pop上一界面
// [self.navigationController popToRootViewControllerAnimated:YES];//pop主视图控制器界面
// [self.navigationController popToViewController:(UIViewController *) animated:YES];//当存在多个页面时,自定义pop到哪一个页面
}
