我发现了这个bug,与iPad Air上的64位处理有关。我有一个UIImageView +类别文件来尝试并始终显示垂直滚动条。这个文件引发了这个问题,我将其删除以修复该错误。希望这可以帮助别人。谢谢
@implementation UIImageView (ForScrollView)
- (void) setAlpha:(float)alpha {
if (self.superview.tag == noDisableVerticalScrollTag) {
if (alpha == 0 && self.autoresizingMask == UIViewAutoresizingFlexibleLeftMargin) {
if (self.frame.size.width < 10 && self.frame.size.height > self.frame.size.width) {
UIScrollView *sc = (UIScrollView*)self.superview;
if (sc.frame.size.height < sc.contentSize.height) {
return;
}
}
}
}
if (self.superview.tag == noDisableHorizontalScrollTag) {
if (alpha == 0 && self.autoresizingMask == UIViewAutoresizingFlexibleTopMargin) {
if (self.frame.size.height < 10 && self.frame.size.height < self.frame.size.width) {
UIScrollView *sc = (UIScrollView*)self.superview;
if (sc.frame.size.width < sc.contentSize.width) {
return;
}
}
}
}
[super setAlpha:alpha];
}
@end
你做了我的一天,非常感谢。 – ViruMax 2015-02-06 07:05:36
