我使用icarousel创建了coverflow效果，但是我没有在xib中以编程方式添加了两个按钮，并且我定义了出口和动作并为该按钮连接了..但是这些按钮显示为图像并且不起作用...这是我的代码.m 文件

@interface GoldViewController ()<UIActionSheetDelegate>

@property (nonatomic, assign) BOOL useButtons;

@end

@implementation GoldViewController

@synthesize carousel1;

-(IBAction)showhome:(id)sender{

ViewController *sec=[[ViewController alloc]initWithNibName:Nil bundle:Nil];
sec.modalTransitionStyle=UIModalTransitionStyleCoverVertical;
[self presentModalViewController:sec animated:YES];

} 

-(IBAction)showback:(id)sender{

CollectionsViewController *sec=[[CollectionsViewController alloc]initWithNibName:Nil bundle:Nil];
sec.modalTransitionStyle=UIModalTransitionStyleCoverVertical;
[self presentModalViewController:sec animated:YES];

}

{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
carousel1.type = iCarouselTypeCylinder;
}

{
[super viewDidUnload];
// Release any retained subviews of the main view.
}

                      [UIImage imageNamed:@"ear1.jpg"],

[button setImage:(UIImage*)[buttonImage objectAtIndex:index] forState:UIControlStateNormal];

确保 nib 文件的所有者肯定是 GoldViewController。检查您是否确实将按钮作为按钮而不是图像添加到笔尖。确保每个相关按钮上的 touchupinside 操作都连接到 nib 文件所有者中的 showhome 和 showback 操作。

如果所有这些都正常，那么当显示视图控制器视图时，iCarousel 的视图可能会覆盖您的按钮视图。（我似乎记得 iCarousel 没有在运行时将视图布置在与 nib 中定义的相同位置但不记得细节的一些问题）。要找出答案 - 在 vi​​ewWillAppear 方法中记录按钮和 iCarousel 视图的框架。
