我看過所以不能找到答案。我從呈現模式的看法:模態視圖模態視圖不顯示
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
ICObservationEditController *controller = [[ICObservationEditController alloc] initWithObservation:[self.observations objectAtIndex:indexPath.row]];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
navController.navigationBar.barStyle = UIBarStyleBlackOpaque;
navController.navigationBar.tintColor = [UIColor grayColor];
[self.editController presentModalViewController:navController animated:YES];
}
一旦提出,作爲一個選項,我想在上面從MessageUI
框架提出了一條短信:
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if([MFMessageComposeViewController canSendText]) {
NSLog(@"presented");
//code here for text body
controller.recipients = [NSArray arrayWithObjects:@"", nil];
controller.messageComposeDelegate = self;
[self.editController presentModalViewController:controller animated:YES];
}
調試器證實了我接收事件,但未提供視圖。代碼是正確的,因爲我已經在其他應用程序中使用完全相同的代碼,但尚未在模態視圖中使用。
從已經以模態方式呈現的視圖呈現模態視圖不是一種好的做法。 http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/ModalViewControllers/ModalViewControllers.html – satheeshwaran 2013-05-02 17:46:32
