UIActivityViewController中缺少共享服务

Question

我正在使用UIActivityViewController在我的项目*享和邮寄。

但只有邮件服务和消息服务显示，但不是脸谱，微博和其他服务。显示UIActivityviewController

NSURL *shareUrl = [NSURL URLWithString:@"http://www.captechconsulting.com"]; 
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil]; 
activityViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical; 


[self presentViewController:activityViewController animated:YES completion:nil]; 

OS

NSArray *activityItems = [NSArray arrayWithObjects: shareUrl, nil]; 

//代码：ios7

是否依赖于iPhone设置？ 我已经启用权限和我尝试过，但结果是一样的....

Answer 1

你必须在你的设备设置添加帐户，

Setting > Facebook
Setting > Twitter

设置它比尝试，

NSURL *shareUrl = [NSURL URLWithString:@"http://www.captechconsulting.com"]; 
NSArray *activityItems = [NSArray arrayWithObjects: shareUrl, nil]; 
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil]; 
activityViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical; 

[self presentViewController:activityViewController animated:YES completion:nil]; 

如果您分享的图像也比相关的活动将显示。
