Question

如何从此IBAction调用以下方法？我想调用prepareForSegue：方法而不是NSLog（@“clicked”）;

这是IBAction：

- (IBAction) annotationViewClick:(id) sender {
    NSLog(@"clicked");
}

以下是方法：

// Do some customisation of our new view when a table item has been selected
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Make sure we're referring to the correct segue
    if ([[segue identifier] isEqualToString:@"ShowMoreInfo"]) {

        // Get reference to the destination view controller
        MoreDetailViewController *mdvc = [segue destinationViewController];


        [mdvc setSelectedItemName:[NSString stringWithFormat:@"%@", placeName.text]];
        [mdvc setSelectedItemAddress:[NSString stringWithFormat:@"%@", placeFormattedAddress.text]];

        [mdvc setSelectedItemWeb:[NSString stringWithFormat:@"%@", placeWebsite.text]];
        [mdvc setSelectedItemRating:[NSString stringWithFormat:@"%@", placeRating.text]];
  //      [mdvc setSelectedItemDistance:[NSString stringWithFormat:@"%@", placeDistance.text]];

    }
}

感谢您的帮助！

Answer 1

执行segue时，

prepareForSegue:方法会自动调用。

要执行segue，您应该使用performSegueWithIdentifier:，对于前[self performSegueWithIdentifier:@"showGuide" sender:self];，

在这种情况下，您需要在Xcode Interface Builder中为segue分配标识符。

尝试类似

的内容

UIStoryBoardSegue *segue = ... setup the one you want
[self performSelector:@selector(prepareForSegue:) withObject:seque afterDelay:0];

我从未使用过故事板 - 但这就是你如何称呼选择器：）
