如何在Carousel中选择图像并转到iPhone中的下一个视图

Question

我正在制作一个由旋转木马组成的iPhone应用程序。请任何人都可以告诉我们如何对所选的Carousel图像执行操作。

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

我正在努力实现这一点，但它没有给出正确的结果，请任何人都能说出正确的实施

感谢

一旦尝试这样，

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index
{

        UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"%@",[menuViews objectAtIndex:index]]];
        _reflectionView =[[[ReflectionView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, image.size.width, image.size.height)] autorelease];
        UIButton *button = [[[UIButton alloc] initWithFrame:CGRectMake(0, 0, image.size.width, image.size.height)] autorelease];
        [button setBackgroundImage:image forState:UIControlStateNormal];
        [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        button.titleLabel.font = [button.titleLabel.font fontWithSize:14];
        [button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
        button.tag = index;
        [_reflectionView addSubview:button];

    return _reflectionView;
}

在上面的代码中，menuViews是图像数组。

- (void)buttonTapped:(UIButton *)sender
{   
    NSLog(@"%d",sender.tag);//based on tag value you can do whatever you want
}

像这样设置iCarousel的DataSource和Delegate

而在.h文件中为您的iCarousel设置ViewController代理

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

@interface iCarouselViewController : UIViewController<iCarouselDataSource, iCarouselDelegate>

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

@end

在.m文件中，像这样编写委托方法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];

}
