view页面跳转

当一个View将要展现时触发该方法,可在该方法中准备将要展现到VIEW中的数据,比如重连数据库读取数据到NSMutableArray中然后通过[tableView reloadData]刷新tableView的显示内容!

View A 跳转方法
addStudentViewController *add; //View B
-(IBAction)addClicked:(id)sender{
       add=[[addStudentViewController alloc]initWithNibName:@"addStudent" bundle:nil];
      [self.view addSubview:add.view]; 
}
//View B 中的退出方法
-(IBAction)doneBtnClicked:(id)sender{
       [self.view removeFromSuperview];
}

以下方法实现View跳转则触发!
-------------------------------------
View A 跳转方法
addStudentViewController *add; //View B
-(IBAction)addClicked:(id)sender{
      add=[[addStudentViewController alloc]initWithNibName:@"addStudent" bundle:nil];
      [self presentModalViewController:add animated:YES];
}
View B 中的退出方法
-(IBAction)doneBtnClicked:(id)sender{
     [self.parentViewController dismissModalViewControllerAnimated:YES];
}
