我正在使用 iCarousel 来显示信息。每个索引(共 7 个)都有一个唯一的图像,上面有一个标签。每个都用 if 语句设置 if (index == 0){...}
etc.
但是,当我加载页面(和轮播)时,最初只加载前三个图像。系统使用延迟加载等到轮播转来抓取下一张图片。我可以通过打印语句证明索引确实增加超过 2 一直到 6 [0..6]。但由于某种原因,我的轮播图片在第三张之后重复出现。
示例:周一、周二、周三、周一、周二、周三、周一 应该是:周一、周二、周三、周四、周五、周六、周日
任何想法如何解决这个问题?
更多测试 对于索引 0-2, View 为 nil,但对于索引 3+, View 不是 nil,并且 if 被跳过。知道如何解决这个问题吗?

}
} else if (index == 1) {
label.backgroundColor = [UIColor colorWithPatternImage:[self resizeForCarousel:[UIImage imageNamed"Tuesday_Hours.jpg"]]];
} else if (index == 2){
label.backgroundColor = [UIColor colorWithPatternImage:[self resizeForCarousel:[UIImage imageNamed"Wednesday_Hours.jpg"]]];
} else if (index == 3){
label.backgroundColor = [UIColor colorWithPatternImage:[self resizeForCarousel:[UIImage imageNamed"Thursday_Hours.jpg"]]];
} else if (index == 4){
label.backgroundColor = [UIColor colorWithPatternImage:[self resizeForCarousel:[UIImage imageNamed"Friday_Hours.jpg"]]];
} else if (index == 5){
label.backgroundColor = [UIColor colorWithPatternImage:[self resizeForCarousel:[UIImage imageNamed"Saturday_Hours.jpg"]]];
} else if (index == 6){
label.backgroundColor = [UIColor colorWithPatternImage:[self resizeForCarousel:[UIImage imageNamed"Sunday_Hours.jpg"]]];
}
label.textAlignment = NSTextAlignmentCenter;
//label.textAlignment = UITextAlignmentCenter;
label.font = [label.font fontWithSize:50];
label.tag = 1;
[view addSubview:label];
}
else
{
label = (UILabel *)[view viewWithTag:1];
}
return view;
}
关键是去掉if(view == nil)
前 3 个索引点是有效的,但之后它们被启动并且不再为 nil
关于ios - iCarousel - viewForItemAtIndex 在启动时加载所有索引,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/24771931/
