我正在制作一个包含旋转木马的 iPhone 应用程序。请任何人告诉我们如何对 Carousel 的选定图像执行操作。

- (void)carousel:(iCarousel *)crsl didSelectItemAtIndex:(NSInteger)index { }

我正在尝试实现这个但它没有给出正确的结果请任何人告诉这个正确的实现

Answer 1

像这样设置iCarousel的DataSource和Delegate

然后在 .h 文件中为 iCarousel 设置 ViewController Delegate

#import <UIKit/UIKit.h>
#import "iCarousel.h"

@interface iCarouselViewController : UIViewController<iCarouselDataSource, iCarouselDelegate>

@property (strong, nonatomic) NSMutableArray *images;
@property (nonatomic, retain) IBOutlet iCarousel *carousel;

@end

然后在 .m 文件中像这样编写委托(delegate)方法 didSelectItemAtIndex

    -(void)carousel:(iCarousel *)carousel didSelectItemAtIndex:(NSInteger)index
{

    UIImage * img = [images objectAtIndex:index];

    ImageViewController *aImageViewController = [[ImageViewController alloc] initWithNibName:@"ImageViewController" bundle:nil];

    aImageViewController.image = img;   //this code is used to send image to another view not tested

    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:aImageViewController];
    navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;

//this code used for present second-view controller that display selected image
    navigationController.topViewController.title = @"Greeting's";
    [self presentModalViewController:navigationController               animated:YES];
    [navigationController release];

}
