我有两个视图：登录页面和注册页面。如果在用户导航到另一个视图时显示键盘，我希望程序自行关闭键盘。但是从注册页面导航回登录页面后，键盘会自动显示。另一件事是，当我从显示键盘的注册页面切换回登录页面时，它会关闭登录键盘而不是注册键盘。
这是我的代码。
-(void) viewWillDisappear:(BOOL)animated {
[currentTextField resignFirstResponder];
}
-(IBAction) registerButton:(id)sender {
Registers *registerview = [[Registers alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:registerview animated:NO];
}
-(IBAction)back:(id)sender {
[self dismissModalViewControllerAnimated:YES];
}
当我使用登录视图上显示的键盘导航以注册视图时的控制台日志。
