当单击电子邮件选项时，崩溃发生在 UIActivityController 中。这仅在首次启动时发生。我堆栈跟踪我没有找到与我的应用程序相关的任何内容。整个跟踪显示在 ios 框架中。有人遇到过这样的问题吗？请帮忙。
这是代码
if(NSClassFromString(@"UIActivityViewController")) {
// iOS 6
NSMutableArray *activityItems = [[NSMutableArray alloc] init];
NSMutableArray *applicationActivities = [[NSMutableArray alloc] init];
if ([UIPrintInteractionController isPrintingAvailable])
{
UIViewPrintFormatter *formatter = [self.descriptionWebview viewPrintFormatter];
[activityItems addObject:formatter];
}
if (pdfLink)
{
[activityItems addObject:pdfLink];
PDFActivity *pdfActivity = [[PDFActivity alloc] init];
[applicationActivities addObject:pdfActivity];
}
MailActivityItemSource *mailItemSource = [[MailActivityItemSource alloc] initWithInsightsObject:insightsObj];
[activityItems addObject:mailItemSource];
UIActivityViewController* shareMenu = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:applicationActivities];
[shareMenu setCompletionHandler:^(NSString *activityType, BOOL completed) {
[self dismissActivityController];
[self LoadPage];
}];
shareMenu.excludedActivityTypes = @[UIActivityTypePostToFacebook, UIActivityTypePostToWeibo];
// [self presentModalViewController:shareMenu animated:YES];
[self presentViewController:shareMenu animated:YES completion:Nil];
}
else {
这是日志：
