Question

我已经使用icarousel创建了coverflow效果，但我添加了两个按钮，而不是通过编程方式在xib中我定义了插座和动作并连接了那些按钮..但这些按钮显示为图像而不工作......这是我在.m文件中的代码

@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];

}

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

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

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{ 
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);

return NUMBER_OF_ITEMS;
}

UIImage *buttonImage=[NSArray arrayWithObjects:[UIImage imageNamed:@"ban.jpg"],
                      [UIImage imageNamed:@"pen.jpg"],
                      [UIImage imageNamed:@"ear1.jpg"],

                      [UIImage imageNamed:@"brac.jpg"],
                      [UIImage imageNamed:@"rings.jpg"],nil];

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 250.0f, 320.0f);

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

[button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
return button;



}

{
return ITEM_SPACING;
}



- (BOOL)carousel:(iCarousel *)_carousel shouldSelectItemAtIndex:(NSInteger)index
{
if (index == carousel1.currentItemIndex)
{
    NSLog(@"Should select current item");
}
else
{
    NSLog(@"Should select item number %i", index);
}
return YES;
 }

- (void)carousel:(iCarousel *)_carousel didSelectItemAtIndex:(NSInteger)index
{
if (index == carousel1.currentItemIndex)
{
    //note, this will only ever happen if useButtons == NO
    //otherwise the button intercepts the tap event
    NSLog(@"Did select current item");
}
else
{
    NSLog(@"Did select item number %i", index);
}
 }

确保nib文件所有者绝对是GoldViewController。检查您是否已将按钮添加到笔尖作为按钮而不是图像。确保每个相关按钮上的touchupinside操作连接到nib文件所有者中的showhome和showback操作。

如果所有这些都没问题，则可能在显示视图控制器视图时，iCarousel的视图覆盖了按钮视图。（我似乎回想起iCarousel的一些问题，而不是在运行时将视图布置在与nib中定义的相同的位置，但不记得细节）。要找出 - 在viewWillAppear方法中记录按钮框架和iCarousel视图。

xib中定义的方法不能正常工作
