ios – UIActivityViewController有一个奇怪的大小和形状

我只是为我提供了这个错误报告…活动视图控制器突然出现这种奇怪的狭窄形状,无论我是在实际的手机还是视图控制器上.

这种情况发生在一些普通的香草代码中,这些代码几个月没有被触及：

UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[message] applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];

怎么可能出错？我甚至无法想到从哪里开始排除故障.

解决方法

在某些情况下可能会发生.试试这个

NSArray *Items   = [NSArray arrayWithObjects:
                    @"Checking Test App",nil];
UIActivityViewController *activity=[[UIActivityViewController alloc]initWithActivityItems:Items applicationActivities:nil];
[self presentViewController:activity animated:YES completion:nil];

要么

NSString *string = NSLocalizedString(@"shareString",nil);
UIActivityViewController *activityViewController = [[UIActivityViewController alloc]
                                                    initWithActivityItems:@[string] applicationActivities:nil];

[activityViewController setCompletionWithItemsHandler:
 ^(NSString *activityType,BOOL completed,NSArray *returnedItems,NSError *error)
 {
     if ( completed ) {
         NSLog(@"sharing complete");
     } else
     {
         NSLog(@"cancelled");
     }
 }];

[self presentViewController:activityViewController animated:YES completion:^{
}];
