I am getting this error and I tried to change 'UIAlertView' to 'UIAlertController'still getting different errors.
You can replace in xCode build with below UIAlertController:
UIAlertController *alert = [UIAlertController
alertControllerWithTitle:#"Error" message:#"Camera not available"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *ok = [UIAlertAction actionWithTitle:#"Ok" style: style:UIAlertActionStyleDefault handler:nil];
[alert addAction:ok];
[self presentViewController:alert animated:YES completion:nil];
self.infoView.hidden = NO;
self.infoView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.7];
i want to call thin in table view
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row==0) {
return;
}
NSMutableDictionary *Tag_Dic = [NSMutableDictionary dictionary];
[Tag_Dic setObject:[NSNumber numberWithInteger:indexPath.row] forKey:#"Tags"];
[[NSNotificationCenter defaultCenter] postNotificationName:#"MoveToNext" object:self userInfo:Tag_Dic];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setInteger:indexPath.row forKey:#"SenderTag"];
[defaults synchronize];
}
Try this. You have to show alertController when tapped on UITableViewCell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
[cell.button addTarget:self action:#selector(presentAlert) forControlEvents:UIControlEventTouchUpInside];
}
Then write your code for UIAlertController in presentAlert selector.
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"Title"
message:#"message"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction
actionWithTitle:#"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
}];
UIAlertAction* cancel = [UIAlertAction
actionWithTitle:#"Cancel"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[self presentViewController:alert animated:YES completion:nil];
If you want to show alert when tableview cell is clicked then do following in didSelectRowAtIndexPath method.
For iOS 9 and earlier,
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Title" message:#"Message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Button1",#"Button2", nil];
alertView.delegate = self;
[alertView show];
and user UIAlertView's delegate method to implement your logic when button is clicked
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
For iOS 9 and onwards (UIAlertView is deprecated.)
UIAlertAction *actionOK = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
//handel when OK button is pressed.
}];
UIAlertAction *actionCancel = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
//handel when Cancel button is pressed.
}];
UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:#"Title" message:#"Message" preferredStyle:UIAlertControllerStyleAlert];
[alertVC addAction:actionOK];
[alertVC addAction:actionCancel];
[self presentViewController:alertVC animated:true completion:nil];
In ios 8.3 and earlier work this code,
- (void)saveButton {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Title" message:#"Message" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
}
After 8.4 popup action used UIAlertController and i have create the UITextField in popup view and action is give below,
- (void)callAlert {
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:#"Enter Folder Name"
message:#"Keep it short and sweet"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction actionWithTitle:#"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action){
//Do Some action here
UITextField *textField = alert.textFields[0];
NSLog(#"text was %#", textField.text);
}];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:#"Cancel" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
NSLog(#"cancel btn");
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = #"folder name";
textField.keyboardType = UIKeyboardTypeDefault;
}];
[self presentViewController:alert animated:YES completion:nil];
}
Finally call this method where you want, hope its helpful.
i Create two buttons of UIAlertcontroller:
One Button - "OpenCamera"
Two button - "OpenGallery"
I just can not understand how I create action when I click on one of them.
- (IBAction)takePic:(id)sender {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil
message:nil
preferredStyle:UIAlertControllerStyleActionSheet]; // 1
UIAlertAction *openCamrea = [UIAlertAction actionWithTitle:#"open camrea"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
}];
UIAlertAction *openGallery = [UIAlertAction actionWithTitle:#"open gallery"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
}];
[alert addAction:openCamrea];
[alert addAction:openGallery];
[self presentViewController:alert animated:YES completion:nil];
}
The handler is the block to be executed on the selection of the item.
UIAlertAction *openGallery = [UIAlertAction
actionWithTitle:#"open gallery"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
// Code to run when the open gallery option is pressed.
}];
BTW I think the long unbroken lines in the question really don't help as they effectively hide the key parameter.
The complete code:
- (IBAction)takePic:(id)sender {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil
message:nil
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *openCamrea = [UIAlertAction actionWithTitle:#"open camrea"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action)
{
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Error"message:#"Device has no camera"delegate:nil cancelButtonTitle:#"OK"otherButtonTitles: nil];
[myAlertView show];
}
else
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
}];
UIAlertAction *openGallery = [UIAlertAction actionWithTitle:#"open gallery"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action)
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}];
[alert addAction:openCamrea];
[alert addAction:openGallery];
[self presentViewController:alert animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.img.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Put your code inside the handler blocks you are passing to [UIAlertAction actionWithTitle:style:handler:]
For example:
UIAlertAction *openCamrea = [UIAlertAction actionWithTitle:#"open camrea"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
// openCamera action code goes here
}];
UIAlertAction *openGallery = [UIAlertAction actionWithTitle:#"open gallery"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
// openGallery action code goes here
}];

I have two issues after usage of MFMailComposeViewController in my application:
After the MFMailComposeViewController is dismissed, the UITextField text on my initial ViewController is cleared
When attempting to display a UIAlertController to indicate a MFMailComposeResult, it fails to display giving a error in the log.
For issue 1: This is my MFMailComposeViewController code. It is an action of a UIAlertController (with UIAlertControllerStyleActionSheet).
UIAlertAction *email = [UIAlertAction
actionWithTitle:#"Email the link"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
// composes new mail message with link
NSString *messageBody = self.link.text;
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setMessageBody:messageBody isHTML:NO];
// customises UI to match application
[[mc navigationBar] setTintColor:[UIColor whiteColor]];
[self presentViewController:mc animated:YES completion:^{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
[self setNeedsStatusBarAppearanceUpdate];
}];
[view dismissViewControllerAnimated:YES completion:nil];
}];
For issue 2: this is my code for displaying an appropriate UIAlertController for each relevant MFMailComposeResult.
- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
case MFMailComposeResultCancelled:{
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:#"SearchMe"
message:#"The composition of this email has been cancelled."
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *done = [UIAlertAction
actionWithTitle:#"Done"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:done];
[self presentViewController:alert animated:YES completion:nil];
[alert dismissViewControllerAnimated:YES completion:nil];
}
break;
case MFMailComposeResultSaved:{
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:#"SearchMe"
message:#"The composition of this email has saved as a draft."
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *done = [UIAlertAction
actionWithTitle:#"Done"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:done];
[self presentViewController:alert animated:YES completion:nil];
[alert dismissViewControllerAnimated:YES completion:nil];
}
break;
case MFMailComposeResultSent:{
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:#"SearchMe"
message:#"The composition of this email has been sent."
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *done = [UIAlertAction
actionWithTitle:#"Done"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:done];
[self presentViewController:alert animated:YES completion:nil];
[alert dismissViewControllerAnimated:YES completion:nil];
}
break;
case MFMailComposeResultFailed:
{
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:#"SearchMe"
message:#"The composition of this email has failed. Please try again."
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *done = [UIAlertAction
actionWithTitle:#"Done"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:done];
[self presentViewController:alert animated:YES completion:nil];
[alert dismissViewControllerAnimated:YES completion:nil];
}
break;
default:
break;
}
[self dismissViewControllerAnimated:YES completion:NULL];
}
The error given in the log is this:
Warning: Attempt to present <UIAlertController: 0x14ed58b90> on <ViewController: 0x14ee1f7f0> whose view is not in the window hierarchy!
