IOS/Objective-C:在 SLComposer 消息后关闭视图控制器
IOS/Objective-C: Dismiss view controller after SLComposer message
我正在尝试在 SLComposer 发送消息后关闭视图控制器。
为此,我在 SLComposer 方法中使用完成块,如下所示:
[myPostSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
switch (result) {
case SLComposeViewControllerResultCancelled:
NSLog(@"Post Canceled");
[self alertPostFail];
break;
case SLComposeViewControllerResultDone:
NSLog(@"Post Successful");
success = 1;
[self dismissUnderlyingVC ];
break;
default:
break;
}
}];
-(void)dismissUnderlyingVC {
LogDebug(@"trying to dismiss Underlying VC");
[self dismissViewControllerAnimated:YES completion:nil];
}
然而,尽管我将解雇放在完成块中,它在 SLComposer 实际被解雇之前触发,并没有解雇下一个 VC 并给出以下错误:
-[myVC dismissUnderlyingVC][Line 227] [DEBUG]
trying to dismiss Underlying VC
2018-08-28 20:23:59.579416-0400 idaru[1772:662392]
[core] SLComposeViewController skipping explicit
dismiss because isBeingDismissed is already 1
2018-08-28 20:23:59.588142-0400
idaru[1772:662392] [core] SLComposeViewController dealloc
我了解到 SLComposer 没有委托,所以想知道如何确定它实际上已被解雇,以便我可以解雇它下面的下一个 VC。
提前感谢您的任何建议。
您的视图控制器当前正在呈现 SLComposeViewController
。
因此,当您在 self
上调用 dismissViewControllerAnimated:completion:
时,您实际上是在要求关闭 SLComposeViewController
(它已经在被关闭的过程中)。
尝试让 presentingViewController
关闭:
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil];
