我有一个只在 IOS 7 中发生的崩溃，我无法重现它，但它经常发生。有人有答案或至少知道问题出在哪里吗？ 我已经删除了所有关于 ios7 的警告，但崩溃仍然发生。 附上日志。

最佳答案
我遇到了同样的问题。奇怪的是它只出现在 3.5inch 设备(ip4，ip4S)，os7.x。在 ip5 上工作正常。
更新:我们的团队找到了根本原因。这是因为我们在代码中使用了这个动画。
[UIView animateWithDuration:0.4f delay:0 usingSpringWithDamping:0.5f initialSpringVelocity:0.3f options:UIViewAnimationOptionCurveEaseOut animations:^{
self.transform = CGAffineTransformMakeScale(sx,sy);
} completion:^(BOOL finished) {
self.hidden = !visible;
}];
为了修复错误，我们避免在 iOS <8.0 时运行动画
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1) {
[UIView animateWithDuration:0.4f delay:0 usingSpringWithDamping:0.5f initialSpringVelocity:0.3f options:UIViewAnimationOptionCurveEaseOut animations:^{
self.transform = CGAffineTransformMakeScale(sx,sy);
} completion:^(BOOL finished) {
if (finished) {
self.hidden = !visible;
}
}];
} else {
self.transform = CGAffineTransformMakeScale(sx,sy);
self.hidden = !visible;
}
希望对您有所帮助!
