I'm trying to develop a 'passwordless' registration form using a QRCode. The background processing works (can authenticate user), but noting happens visually until the registration is complete and the user is redirected to the apps main ViewController, however, A progress dialog with spinner is supposed to appear during the registration process but it doesn't. If, I manually input the credentials and press 'authenticate', everything works as expected, Just not after scanning the QR code.
Please see code below:
#interface ViewControllerRegister (){
JGProgressHUD *HUD;
NSString *regid;
NSString *regpin;
NSMutableDictionary *dicto;
}
//OPEN QRCODE READER VC
- (IBAction)scanAction:(id)sender
{
if ([QRCodeReader supportsMetadataObjectTypes:#[AVMetadataObjectTypeQRCode]]) {
static QRCodeReaderViewController *vc = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
QRCodeReader *reader = [QRCodeReader readerWithMetadataObjectTypes:#[AVMetadataObjectTypeQRCode]];
vc = [QRCodeReaderViewController readerWithCancelButtonTitle:#"Cancel" codeReader:reader startScanningAtLoad:YES];
vc.modalPresentationStyle = UIModalPresentationFormSheet;
});
vc.delegate = self;
[vc setCompletionWithBlock:^(NSString *resultAsString) {
// NSLog(#"Completion with result: %#", resultAsString);
}];
[self presentViewController:vc animated:YES completion:NULL];
}
else {
[self showAlert:#"Reader not supported by the current device"];
}

It seems you don't use dependency manager like CocoaPods. Probably you add AFNetworking library manually. You must check your target name in
Show the File in inspector for the .m file of AFHTTPSessionManager.
I wrote an iOS app in Objective-C. Xcode version is 8. It works fine on all devices and iOS versions but when I tried to test this in the iOS device running iOS 11. The “Profile Page” stopped working in the sense that once we navigate to that screen, it becomes touch unresponsive and nothing happens. This page works well with all iOS versions and all device except for those running iOS 11.
Code for Profile page is:
#import "ProfileViewController.h"
#interface ProfileViewController ()
#end

Here is my code
I am adding uitextfield to alertview , what I need is to get the data from the array to uitextfield with multiple lines and should be editable.
NSString *selected = [lineItemsArray objectAtIndex:indexPath.row];
UIAlertController *controller = [UIAlertController alertControllerWithTitle:#"Notice" message:#"Selected" preferredStyle:UIAlertControllerStyleAlert];
[controller addTextFieldWithConfigurationHandler:^(UITextField *linetextField)
{
linetextField.text=selected;
}];
UIAlertAction *alertAction = [UIAlertAction actionWithTitle:#"Okay"
style:UIAlertActionStyleDestructive
handler:^(UIAlertAction *action) {
[self.navigationController popViewControllerAnimated:YES];
NSLog(#"Dismiss button tapped!");
}];
[controller addAction:alertAction];
[self presentViewController:controller animated:YES completion:nil];
PackageLineItemViewController *pLineVC = [[PackageLineItemViewController alloc]init];
pLineVC.view.backgroundColor = [UIColor whiteColor];
[self.navigationController pushViewController:pLineVC animated:YES];
[self.view endEditing:YES];
I tried the solution for your question.If you use alertViewController with textField you can't set multiple line.For label you can set multiple line but for textfield you can't set.

The printed output results are
The textField text is - iOS, Android, Windows
UITextFIeld is specific to one line. you cannot have multi-line textfeild. IF you need multi line , you should go for UITextView. Again you cannot add UITextView to the alert controller. You need to build a custom alert view.
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:#[message] applicationActivities:nil];
activityVC.excludedActivityTypes = nil;
[activityVC setCompletionHandler:^(NSString *activityType, BOOL completed)
{
activityVC.completionHandler = nil;
// if (completed)
// [Utils alertMessage:kNSLocalizedString(#"TITLE20_KEY#0", nil) title:nil delegate:nil cancelButton:kNSLocalizedString(#"OK_KEY#0", nil) otherButton:nil hiden:nil];
[activityVC dismissViewControllerAnimated:YES completion:^{
_isSharing = NO;
}];
}];
if ([self respondsToSelector:#selector(popoverPresentationController)]) {
activityVC.popoverPresentationController.sourceView = self.view;
}
[self presentViewController:activityVC animated:YES completion:^{
_isSharing = YES;
}];
I am getting the below warning.

Check for your Viewcontroller as its giving self as null.
