我正在使用 NSSharingService 在邮件应用程序中打开电子邮件撰写窗口:
NSSharingService* sharingService = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail];
[sharingService setRecipients:@[@"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d9adbcaaad99bbb5b8b1bbb5b8b1f7bab6b4" rel="noreferrer noopener nofollow">[email protected]</a>"]];
[sharingService setSubject:@"Test"];
sharingService.delegate = self;
它可以很好地打开撰写电子邮件窗口,当我输入一些文本并实际发送电子邮件时,我什至会收到对委托(delegate)的回调:
- (void)sharingService:(NSSharingService *)sharingService didShareItems:(NSArray *)items {
NSLog(@"sharingService didShareItems - %@", sharingService.messageBody);
}
问题是它返回的messageBody总是nil。我期望它包含已发送的电子邮件的文本。我检查了 NSSharingService 的头文件:
/* These read-only properties allow for querying of the shared content:
*/
// Message body as string
@property (readonly, copy) NSString *messageBody NS_AVAILABLE_MAC(10_9);
// URL to access the post on Facebook, Twitter, Sina Weibo, etc. (also known as permalink)
@property (readonly, copy) NSURL *permanentLink NS_AVAILABLE_MAC(10_9);
// Account name used for sending on Twitter or Sina Weibo
@property (readonly, copy) NSString *accountName NS_AVAILABLE_MAC(10_9);
// NSArray of NSURL objects representing the file that were shared
@property (readonly, copy) NSArray *attachmentFileURLs NS_AVAILABLE_MAC(10_9);
知道为什么这可能不起作用吗?如果我使用 NSSharingServiceNameComposeMessage
而不是电子邮件,似乎工作正常,但那是为了发送 iMessage。
最佳答案
不确定为什么它在您的情况下不起作用,但这应该或多或少是要遵循的标准模式:
@interface sharingServiceDelegate : NSObject <NSSharingServiceDelegate>
@end
@interface sharingServiceDelegate ()
@property NSString *recipientString;
@property NSString *subjectString;
@property NSString *bodyString;
@property NSURL <NSPasteboardWriting> *attachmentURL;
@property NSSharingService *emailSharingService;
@end
@implementation sharingServiceDelegate
- (id)init {
self = [super init];
if (self) {
NSSharingService *emailSharingService = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail];
emailSharingService.delegate = self;
self.emailSharingService = emailSharingService;
}
return self;
}
- (BOOL)shareUsingEmail
{
NSArray *shareItems =@[_bodyString, _attachmentURL];
self.emailSharingService.recipients = @[_recipientString];
self.emailSharingService.subject = _subjectString;
if([self.emailSharingService canPerformWithItems:shareItems]){
[self.emailSharingService performWithItems:shareItems];
return TRUE;
} else {
// handle failure ...
}
return FALSE;
}
@end
然后,您实际上可以在任何需要的地方执行这样的共享服务:
sharingServiceDelegate * shareDelegate = [[sharingServiceDelegate alloc] init];
shareDelegate.recipientString = @"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b0c2d5d3d9c0d9d5dec4f0d1d4d4c2d5c3c39ed3dfdd" rel="noreferrer noopener nofollow">[email protected]</a>";
shareDelegate.subjectString = @"a subject";
shareDelegate.bodyString = @"A message body";
shareDelegate.attachmentURL = [NSURL fileURLWithPath:[NSString stringWithCString:file_to_share_path encoding:NSUTF8StringEncoding]];
if([shareDelegate shareUsingEmail]==FALSE)
NSLog(@"Email Sharing Service failed.\n");
}
