在UIPageControl的索引0处自定义带有UIPageControl图像的点 [英] Customize dot with image of UIPageControl at index 0 of UIPageControl

问题描述

我是ios编程的新学习者。我试图在stackoverflow上搜索另一个示例和更多问题，但这不是我的目标。我想在UIPageControl的索引0处设置一个点的图像，类似于iPhone搜索主屏幕。有办法吗？请用一些代码或其他有用的链接向我解释。

您可能需要进行更多自定义

You might have to do some more customization as

-(void) updateDots
{
    for (int i = 0; i < [self.subviews count]; i++)
    {
        UIImageView* dot = [self.subviews objectAtIndex:i];

        if (i == self.currentPage) {
            if(i==0) {
                dot.image = [UIImage imageNamed:@"activesearch.png"];
            } else {
                dot.image = activeImage;
            }        
        } else {
            if(i==0) {
                dot.image = [UIImage imageNamed:@"inactivesearch.png"];
            } else {
                dot.image = inactiveImage;
            }
        }
    }
}
