原因分析：
原因是由于：UIPageControl在
ios 14之后有了变化导致按照框架中的计算宽度方法计算不准确导致的。解决方法需要在SDCycleScrollView.m文件中的layoutSubviews方法中在对UIPageControl进行宽度计算的时候加入对ios 14及以上系统版本的适配代码，大致位置为第513行代码的地方。
解决方法：
- 需要适配的代码如下：
if (@available(iOS 14.0, *)) {
if ([self.pageControl isKindOfClass:[UIPageControl class]]) {
UIPageControl *pageControl = (UIPageControl *)_pageControl;
size.width = [pageControl sizeForNumberOfPages:self.imagePathsGroup.count].width;
}
}
-
pod导入的话就直接更新到最新版本即可。
-
手动拖入项目中解决方案：不好找的话就把下边的
layoutSubviews方法和SDCycleScrollView.m文件中的layoutSubviews方法进行替换。
- (void)layoutSubviews
{
self.delegate = self.delegate;
[super layoutSubviews];
_flowLayout.itemSize = self.frame.size;
_mainView.frame = self.bounds;
if (_mainView.contentOffset.x == 0 && _totalItemsCount) {
int targetIndex = 0;
if (self.infiniteLoop) {
targetIndex = _totalItemsCount * 0.5;
}else{
targetIndex = 0;
}
[_mainView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:targetIndex inSection:0] atScrollPosition:UICollectionViewScrollPositionNone animated:NO];
}
CGSize size = CGSizeZero;
if ([self.pageControl isKindOfClass:[TAPageControl class]]) {
TAPageControl *pageControl = (TAPageControl *)_pageControl;
if (!(self.pageDotImage && self.currentPageDotImage && CGSizeEqualToSize(kCycleScrollViewInitialPageControlDotSize, self.pageControlDotSize))) {
pageControl.dotSize = self.pageControlDotSize;
}
size = [pageControl sizeForNumberOfPages:self.imagePathsGroup.count];
} else {
size = CGSizeMake(self.imagePathsGroup.count * self.pageControlDotSize.width * 1.5, self.pageControlDotSize.height);
// ios14 需要按照系统规则适配pageControl size
if (@available(iOS 14.0, *)) {
if ([self.pageControl isKindOfClass:[UIPageControl class]]) {
UIPageControl *pageControl = (UIPageControl *)_pageControl;
size.width = [pageControl sizeForNumberOfPages:self.imagePathsGroup.count].width;
}
}
}
CGFloat x = (self.sd_width - size.width) * 0.5;
if (self.pageControlAliment == SDCycleScrollViewPageContolAlimentRight) {
x = self.mainView.sd_width - size.width - 10;
}
CGFloat y = self.mainView.sd_height - size.height - 10;
if ([self.pageControl isKindOfClass:[TAPageControl class]]) {
TAPageControl *pageControl = (TAPageControl *)_pageControl;
[pageControl sizeToFit];
}
CGRect pageControlFrame = CGRectMake(x, y, size.width, size.height);
pageControlFrame.origin.y -= self.pageControlBottomOffset;
pageControlFrame.origin.x -= self.pageControlRightOffset;
self.pageControl.frame = pageControlFrame;
self.pageControl.hidden = !_showPageControl;
if (self.backgroundImageView) {
self.backgroundImageView.frame = self.bounds;
}
}
