所以我的UIActivityViewController应用程序中有一个。如何更改背景颜色。而且我还有一个快速如何将 Facebook 和 twitter 添加到我的UIActivityViewController.
编码：
- (IBAction)Social:(id)sender {
UIActivityViewController *social = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:@"Travel+ Rocks",nil] applicationActivities:nil];
social.excludedActivityTypes = @[UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypePostToWeibo,UIActivityTypePrint];
[self presentViewController:social animated:YES completion:nil];
[social setCompletionHandler:^(NSString *activityType, BOOL completed)
{
NSLog(@"Activity = %@",activityType);
NSLog(@"Completed Status = %d",completed);
if (completed)
{
// UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Your Posts were sucessful" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
// [objalert show];
// objalert = nil;
}else
{
// UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Your Posts weren't sucessful" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
// [objalert show];
// objalert = nil;
}
}];
}
这些代码修复了背景错误：
NSString *message = [NSString stringWithFormat:@""];
NSString *textToShare = message;
UIImage *imageToShare = [UIImage imageNamed:@""];
NSArray *activityItems = [[NSArray alloc] initWithObjects:textToShare, imageToShare,nil];
UIActivity *activity = [[UIActivity alloc] init];
NSArray *applicationActivities = [[NSArray alloc] initWithObjects:activity, nil];
UIActivityViewController *activityVC =
[[UIActivityViewController alloc] initWithActivityItems:activityItems
applicationActivities:applicationActivities];
[self presentViewController:activityVC animated:YES completion:nil];
