iphone - 如何在单击按钮时立即打开视图控制器

Question

我正在为 iPhone 开发一个电子商务应用程序，当用户单击即将到来的视图的按钮时，我需要立即打开一个视图，数据从服务器加载大图像，以加载我正在使用后台线程的图像。

谢谢你

Answer 1

很简单，以下是如何UIViewController从IBAction.

- (IBAction)goToNextView:(id)sender
    {
     //if you are using xibs use this line
        UIViewController *controller = [[UIViewController alloc] initWithNibName:@"myXib" bundle:[NSBundle mainBundle]];
    //if you are using storyboards use this line
        UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"myViewControllersID"];

    //to present the controller modally use this
        [self presentViewController:controller animated:NO completion:nil];
    //or if you are pushing to this controller using a navigation controller use this
        [self.navigationController pushViewController:controller animated:NO];
    }

一定要传递动画NO，以便立即显示视图。

您可以为此使用模态视图控制器

- (IBAction)showController:(id)sender {
    SampleViewController *sampleView = [[SampleViewController alloc] init];
    [self presentModalViewController:sampleView animated:YES];
}

您需要制作一个按钮，然后添加其操作，例如

-(IBAction)ButtonAction:(id)sender{

CalController *calculateView=[[CalController alloc] initWithNibName:@"CalController" bundle:nil];
[self.navigationController presentModalViewController:calculateView animated:NO];  

}
