Sms 在iOS 7中发送短信它不工作

}

}

当我单击按钮1时，它不工作，并且没有arlet错误

但当点击下面的按钮时，它在iOS 7上正常工作，但我无法分配消息内容。 请指导我如何将消息内容分配给此按钮编号2

- (IBAction)button_number1:(id)sender {


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

[textComposer setMessageComposeDelegate:self];

if ([MFMessageComposeViewController canSendText]) {

    [textComposer setRecipients:@[string_numberphone]];

    [textComposer setBody:@"ABC"];

    [self presentViewController:textComposer animated:YES completion:NULL];

} else {

    NSLog(@"Can't Open Text");

}

}

非常感谢
