【问题描述】:
我正在尝试使用以下代码将 iCarousel 添加到现有项目,但出现此错误:MemberCatalog[14990:1a903] -[MainViewController carousel:viewForItemAtIndex:reusingView:]: unrecognized selector sent to instance 0xa0589b0.
iCarousel.m 中抛出错误的行是:view = [_dataSource carousel:self viewForItemAtIndex:index reusingView:[self dequeueItemView]];
任何帮助将不胜感激。
carouselItems = [NSArray arrayWithObjects:
[UIImage imageNamed:@"iLibrary+Featured_AM-RAH.png"],
[UIImage imageNamed:@"iLibrary+Featured_CCA.png"],
[UIImage imageNamed:@"iLibrary+Featured_GI-PA.png"],
nil];
// Initialize and configure the carousel
carousel = [[iCarousel alloc] initWithFrame:self.view.bounds];
carousel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
carousel.type = iCarouselTypeCoverFlow2;
carousel.delegate = self;
carousel.dataSource = self;
[self.view addSubview:carousel];
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index
{
UIImage *image = [carouselItems objectAtIndex:index];
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:50];
button.tag=index;
return button;
}
【问题讨论】:
-
您是否正在实施
-carousel:viewForItemAtIndex:reusingView:?? -
是的。我做了:- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index { UIImage *image = [carouselItems objectAtIndex:index]; UIButton *button = [[[UIButton alloc] initWithFrame:CGRectMake(0, 0, image.size.width, image.size.height)] autorelease]; [按钮 setBackgroundImage:image forState:UIControlStateNormal]; [按钮 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; button.titleLabel.font = [button.titleLabel.font fontWithSize:50]; button.tag=索引;返回按钮; }
-
嗯,这个方法显然缺少
reusingView:部分 -
谢谢你们,你们是最棒的。我正在实施 - (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index 而不是 - (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view跨度>
-
我会发布一个答案,以便您关闭此问题。 ;)
