我没有使用LaunchScreen.xib。我正在使用故事板进行启动画面。我正在调用API来获取启动图像。我在app delegate中这样做。我可以在视图控制器上显示图像,但是一旦显示图像,我就无法转到另一个控制器。
以下是AppDelegate中的内容:
-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
self.window.frame=CGRectMake(0, 200, 100,30);
[self.window addSubview:[self convertImage: image]];
//upto here everything is fine
//now i am trying to wait for 3 seconds and call another view controller
sleep(3);
ViewController *login=[[ViewController alloc]initWithNibName:@"Login" bundle:nil];
[self presentviewcontroller:....]; // not able to present another controller
}

您可以使用:
[[self window].rootViewController presentViewController:login animated:YES completion:nil];
