MFMessageComposeViewController显示黑屏/白屏 [英] MFMessageComposeViewController shows blank/white screen

问题描述

if([MFMessageComposeViewController canSendText])
{
    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

    controller.body = @"This is a test!";

    controller.recipients = [NSArray arrayWithObject:phones];

    controller.messageComposeDelegate = self;

    [self presentViewController:controller animated:YES completion:nil];
}

此代码使整个屏幕变白/变黑。有建议吗？

This code makes the entire screen white/blank. Any suggestions?

推荐答案

问题出在这一行：

controller.recipients = [NSArray arrayWithObject:phones];

这是一个格式错误的电话＃阵列。不确定格式错误的电话＃为何没有引发错误，但是将其过滤掉可以解决问题。

It was a malformed phone # array. Not sure why the malformed phone # didn't raise an error, but filtering it out fixed the problem.
