app hang due to alert view &ActionSheet in iOS sdk

Question

I have a textView & on TextViewDidEndEditing , i show a alert with two buttons save? Yes No.

I have also the image Button, when it is clicked i resignFirstResponder for textview, so the alert will be shown & also shows the action sheet.

But the action sheet buttons are not clickable & app got hang. Nothing is happen....

My code is as follows:

-(void)textViewDidEndEditing:(UITextView *)textView
{
UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"" message:@"Do you want to save this note?" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
    [alt setTag:1];
    [alt show];
}

-(IBAction)image_button:(id)sender
{
[MYTextView resignFirstResponder];
UIActionSheet *ac=[[UIActionSheet alloc]initWithTitle:@"Select the Option" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Photo Library",@"Camera Capture", nil];
    ac.tag=4;
    ac.delegate = self;
    ac.backgroundColor=[UIColor blackColor];
    [ac showInView:self.view];
}

Answer 1

ResignFirstResponder triggers textViewDidiEndEditing. So basically you are showing the UIAlertVIew and the ActionSheet at the same time, I guess that is the problem.

Please define your UI flow and try to seperate these 2.

Answer 2

hear i wrote code for implementing this hops this helps

  #import "ViewController.h"

 @interface ViewController ()<UITextViewDelegate,UIAlertViewDelegate,UIActionSheetDelegate>

 @end

 @implementation ViewController
 @synthesize aTextView;
 @synthesize aButton;

- (void)viewDidLoad
{
    [super viewDidLoad];
     self.aTextView.delegate = self;

// Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
 {
     [super didReceiveMemoryWarning];
     // Dispose of any resources that can be recreated.
 }

 - (void)dealloc {
     [self.aTextView release];
     [self.aButton release];
     [super dealloc];
   }
 -(void)textViewDidEndEditing:(UITextView *)textView
 {



  }
  -(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
 {
      if(buttonIndex == alertView.cancelButtonIndex)
      {
           NSLog(@"cancel");
      }
       else
      {
          NSLog(@"save hear");


          UIActionSheet *aActionSheet = [[UIActionSheet alloc]initWithTitle:@"option" delegate:self cancelButtonTitle:@"cancel" destructiveButtonTitle:nil otherButtonTitles:@"photo lib",@"camara lib", nil];
          [aActionSheet showInView:self.view];
          [aActionSheet release];

      }

   }




  - (IBAction)whenButtonTapped:(id)sender {
      [self.aTextView resignFirstResponder];

      UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"save" message:@"" delegate:self cancelButtonTitle:@"NO" otherButtonTitles:@"YES",nil];
      [alertView show];
      [alertView release];



   }

  -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
   {
     if(buttonIndex == actionSheet.cancelButtonIndex)
       {
           NSLog(@"cancel");
       }
     else if (buttonIndex == 0)
       {
           NSLog(@"save to photo lib");
        }
      else
       {
           NSLog(@"camara lib");
       }
   }

   @end
