模拟器上的 MFMessageComposeViewController - canSendText? [英] MFMessageComposeViewController on Simulator - canSendText?
问题描述
following situation: I want to send in app SMS. This is my code creating the MFMessageComposeViewController:
-(void) showMessageComposerWithText:(NSString*)messageText telNumber:(NSString*)telNumber composeDelegate:(id)delegate
{
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if([MFMessageComposeViewController canSendText])
{
controller.body = messageText;
controller.recipients = [NSArray arrayWithObject:telNumber];
controller.messageComposeDelegate = delegate;
[delegate presentModalViewController:controller animated:YES];
}
}
So I think this is straight forward. When testing in Simulator I get following exception: Application tried to push a nil view controller on target <MFMessageComposeViewController: 0x8a4e090>
. I'm also wondering myself why [MFMessageComposeViewController canSendText]
returns YES
when running the app in the simulator.
When running on the device, everything is working correctly.
I couldn't find anything in the docs/web concerning this strange behavior.
I'm running Xcode 4.3 on OS 10.7.3, Deployment Target is iOS 5.0.
Thanks in advance, tubtub
This problem occurs when you install Messages beta on OS X Lion.
Edit: It also occurs on Mountain Lion when there is an iMessage account configured and enabled. If the account is disabled, it works correctly (canSendText returns NO).
Tip: If you use controller.modalTransitionStyle = UIModalTransitionStylePartialCurl
, you can go back in Simulator by clicking on the curled "page" in the upper left corner.
