Question

我已经实现了2个带有图像和tapGestures的ImageViews，这很好用，现在我想要根据我点击的图像来转换到另一个ViewController。我不知道如何声明我的ImageView应该调用哪个ViewController。

所以我的代码是：

-(void) initImageViews{
self.navigationItem.title = @"Menu";
UIImage *serviceImage = [UIImage imageNamed:@"Service.png"];
self.serviceImageView = [[UIImageView alloc] initWithImage:serviceImage];
[self.serviceImageView setFrame:CGRectMake(20, 20, 48,48 )];
[self.view addSubview:self.serviceImageView];
[self.view setBackgroundColor:[UIColor blackColor]];

UIImage *industryImage = [UIImage imageNamed:@"Industry.png"];
self.industryImageView = [[UIImageView alloc] initWithImage:industryImage];
[self.industryImageView setFrame:CGRectMake(73,20,48,48)];
[self.view addSubview:industryImageView];
   UITapGestureRecognizer *singleTap =
    [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];

    [self.industryImageView setUserInteractionEnabled:TRUE];
    [self.serviceImageView setUserInteractionEnabled:TRUE];
    [self.serviceImageView addGestureRecognizer:singleTap];
    [self.industryImageView addGestureRecognizer:singleTap];

 }

    - (void)handleSingleTap:(UITapGestureRecognizer *)gestureRecognizer {

NSLog(@"Tapped!");

 }

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
 {
if ([segue.identifier isEqualToString:@"Service"]) {
    SelectOptionViewController *controller = (SelectOptionViewController*)segue.destinationViewController;
}if ([segue.identifier isEqualToString:@"Industry"]) {
    SelectOptionViewController *controller = (SelectOptionViewController*)segue.destinationViewController;
}
}

}

Answer 1

[self performSegueWithIdentifier:IdentifierForTheSegueiFromStoryBoard sender:nil];

编辑：seque必须存在于故事板中，并且必须具有标识符。

Answer 2

如果您不想/需要使用segues，您可以使用：

if (i want controller A) {
    [self presentViewController:ControllerA animated:YES completion:nil];
} else if (i want controller B) 
    [self presentViewController:ControllerB animated:YES completion:nil];
}

Answer 3

使用标识符在故事板中创建一个segue。然后以编程方式调用这样的segue

[self performSegueWithIdentifier: @"myidentifier" sender: self];

如何通过点击图像以编程方式进行segue？
