发送消息后 MFMessageComposeViewController 未返回到应用程序 ios9

MFMessageComposeViewController not returning to application after send message ios9

之前在 iOS7,我测试了我的 SMS 模块,它运行良好。更新iOS版本后,发现短信模块有问题

在我的 .h 文件中

#import <MessageUI/MFMessageComposeViewController.h>

@interface ViewController : UIViewController<UITextFieldDelegate,MFMessageComposeViewControllerDelegate>

在我的 .m 文件中

- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{
    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
    if([MFMessageComposeViewController canSendText])
    {
        controller.body = bodyOfMessage;
        controller.recipients = recipients;
        controller.messageComposeDelegate = self;
        [self presentModalViewController:controller animated:YES];
    }
}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    if (result == MessageComposeResultCancelled){
        NSLog(@"Message cancelled");
    }
    else if (result == MessageComposeResultSent){
        NSLog(@"Message sent");
    }
    else{
        NSLog(@"Message failed");
    }
}

按发送后,日志中显示"Message sent",但视图仍在消息屏幕上。我不知道为什么它不会返回到我的应用程序。

需要帮助找出为什么它不会返回到我的应用程序的问题。

提前致谢。

看来您并没有在 mailcomposer 出现后将其忽略。您将不得不通过以下方法关闭显示的 MFMessageComposeViewController

-(void)mailComposeController:(MFMailComposeViewController *)controller
         didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error 
{
    if (result == MessageComposeResultCancelled){
        NSLog(@"Message cancelled");
    }
    else if (result == MessageComposeResultSent){
        NSLog(@"Message sent");
    }
    else{
        NSLog(@"Message failed");
    }
    [self dismissViewControllerAnimated:YES completion:nil]; //<---- This line
}

此外,- (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated 已弃用,因为 iOS 6. 像这样使用 - (void)presentViewController:(UIViewController *)viewControllerToPresent animated: (BOOL)flag completion:(void (^)(void))completion

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