MFMessageComposeViewController在iOS7中顯示空白屏幕

Question

當我嘗試使用MFMessageComposeViewController發送大型收件人列表（例如超過40個）時出現問題。 在iOS7中，在顯示SMS撰寫視圖之前，它將顯示20秒或更長時間的空白屏幕。 iOS5和iOS6不會發生這種情況。

以下是我正在使用的現有代碼，

NSArray * recipients;

for (NSIndexPath * index in selectedRows) 
{ 
   NSDictionary *dictionary = [data objectAtIndex:index.row];
   NSString *phoneNum =  [dictionary objectForKey:@"contactNum"];
   recipients = [NSArray arrayWithObjects:phoneNum, nil]];
}

MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

if([MFMessageComposeViewController canSendText])
{
    controller.body = bodyOfMessage;
    controller.recipients = recipients;
    controller.messageComposeDelegate = self ;
    controller.wantsFullScreenLayout = NO;
    [(id)_delegate presentModalViewController:controller animated:YES];
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

以下是我嘗試發送給許多人時收到的輸出消息。

Answer 1

我有一個類似的問題，我在控制台中收到消息“

從com.apple.mobilesms.compose等待籬笆障礙超時

問題是我在我的應用程序中嘗試將數字添加為字符串，但由於本地化請求，我將其放在一個表單中： NSArray *recipents = @[NSLocalizedString(@"numberForRegistrationViaSms", @"")];

和

[messageController setRecipients:@[recipents]];

由於某些原因，這不起作用，但是，當我簡單地說， [messageController setRecipients:@[@"123456789"]]; ，SMS編輯器出現沒有任何問題。

我想到了同樣的問題

controller.recipients = //應該始終是一個字符串數組。

確保發送給controller.recipients的電話號碼是NSString。

Answer 3

我想我可能會解決這個問題：

//必須啟動新的NSString對象

NSString *phoneStr = [NSString stringWithFormat:@"%@",... ];                                                     

MFMessageComposeViewController *aCtrl = [[MFMessageComposeViewController alloc] init];
aCtrl.recipients                      = @[phoneStr];
...

Then OK.

Answer 4

我有同樣的問題。

• 從com.apple.mobilesms.compose等待籬笆障礙超時

• 消息已取消

而不是這個：

    NSString *phoneNumber = @"888888888";
    [picker setRecipients:@[phoneNumber]];

試試這個：

    NSString *phoneNumber = person.phoneNumber;
    [picker setRecipients:@[[NSString stringWithFormat:@"%@", phoneNumber]]];

這對我有用。

該問題已在iOS 7.0.3中得到解決。
