ios8 – UIAlertController错误更改其他UIImageViews的tintcolor

我有我认为是一个奇怪的iOS8错误.每当我启动UIAlertControllerI时,我发现它正在将使用UI ImageRenderingModeAlwaystemplate图像渲染模式的UIImageViews的所有色调颜色更改为深灰色.无论我是否调整UIAlertController的色调颜色,都会发生这种情况.下面找到一个截图(查看气泡角),它们是显示UIAlertController之前的正确颜色,并在解除后返回正确的颜色.

有谁知道在iOS8中如何防止这种情况？

UIAlertController *alertController = [UIAlertController
                                      alertControllerWithTitle:[Nsstring stringWithFormat:@"Question ended %@",[endDateFormat stringFromDate:[NSDate dateWithTimeIntervalSince1970:selectedActivity.utc]]]
                                      message:messageText
                                      preferredStyle:UIAlertControllerStyleActionSheet];
[alertController.view setTintColor:[UIColor colorWithHue:240.0/360 saturation:.03 brightness:.58 alpha:1]];

//...Add some actions and then
[self presentViewController:alertController animated:YES completion:nil];
