目标C短信选项崩溃整个应用程序？

Question

我正在开发一个发送短信的iPhone应用程序，我正在使用XCode 4.2

基本上我需要它来生成一个正文并为收件人添加一个电话号码。

我在iPad上运行该应用程序，它崩溃了应用程序，当我查看代码并发现当我删除此行时，接收行正在解决问题，它完全正常并且它指向消息应用程序。

任何线索如何避免这个问题？

这是我正在使用的代码

MFMessageComposeViewController *sms = [[MFMessageComposeViewController alloc] init];
    if ([MFMessageComposeViewController canSendText]) {
        sms.recipients=[NSArray arrayWithObjects:@"1111111111"];
        sms.body= @"test";
        sms.messageComposeDelegate = self;
        [self presentModalViewController:sms animated:YES];
    }

我收到以下绿色错误：

Tread1 : Program Received signal :"EXC_BAD_ACCESS"

和以下警告（黄色）

Missing sentinel dispatch

Answer 1

sms.receipients=[NSArrayWithObjects:@"1111111111"];

不会起作用。 也不是

sms.recipients=[NSArray arrayWithObjects:@"1111111111"]

尝试

sms.recipients=[NSArray arrayWithObject:@"1111111111"];

arrayWithObjects需要一个nil终止的对象列表。 arrayWithObject只需要一个对象。

Answer 2

写这个作为答案，因为我没有权利发表评论。
我认为问题在于

sms.receipients=[NSArrayWithObjects:@"1111111111"];

应该是

 sms.receipients=[NSArray arrayWithObjects:@"1111111111"];

编辑：

  sms.receipients=[NSArray arrayWithObjects:@"1111111111",nil]; 

要么

  sms.receipients = [NSArray arrayWithObject:@"1111111111"];

Answer 3

现在您已根据收到的错误编辑了问题：

sms.recipients = [ NSArray arrayWithObjects: @"1111111111" ];

需要是：

sms.recipients = [ NSArray arrayWithObjects: @"1111111111", nil ];

你错过了nil sentinel，用于检测arrayWithObjects方法的变量参数的结尾。
