原因分析：
原因是由于：UIPageControl在
ios 14之后有了變化導(dǎo)致按照框架中的計(jì)算寬度方法計(jì)算不準(zhǔn)確導(dǎo)致的店乐。解決方法需要在SDCycleScrollView.m文件中的layoutSubviews方法中在對(duì)UIPageControl進(jìn)行寬度計(jì)算的時(shí)候加入對(duì)ios 14及以上系統(tǒng)版本的適配代碼丹诀，大致位置為第513行代碼的地方著拭。
解決方法：
- 需要適配的代碼如下：
if (@available(iOS 14.0, *)) {
if ([self.pageControl isKindOfClass:[UIPageControl class]]) {
UIPageControl *pageControl = (UIPageControl *)_pageControl;
size.width = [pageControl sizeForNumberOfPages:self.imagePathsGroup.count].width;
}
}
pod導(dǎo)入的話就直接更新到最新版本即可成黄。
手動(dòng)拖入項(xiàng)目中解決方案：不好找的話就把下邊的
layoutSubviews方法和SDCycleScrollView.m文件中的layoutSubviews方法進(jìn)行替換凡恍。
- (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 需要按照系統(tǒng)規(guī)則適配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;
}
}
