Question

My application is freezing with a reason that I could not figure out, it does not crash but it freezes.

basically what I did was having another view inside my view that is hidden at first place, after when I click a button this view will be appeared and it includes a UItextfield and a UIPickerView. the pickerview data is updating while I edt the UItextfield and I select one of the values from picker view then basically press addButton, when I add thi whole view will be hidden again and the selected value of the pickerview will be added another UITextfield in the main view.

when I do this first time it works fine. it sets the value of the UI textfield which is on the main view to the correct value. but when I try to change it, get that view unhidden and select another value in the pcikerview and press on addButton again the application freezes. No crash appears.

I want to inform you about this the value of the UITextfield on the main view is changing I checked it on the logs. and the method that do the clicking action completely works. But it freezes.

I couldnt figure it out, I need some help 🙂

EDIT:

I figure out that the UITextField on the main view cause this freeze, when I set the text

[myTextfield setText:@"somethng"];

the UI freeze. when I comment this out it works pretty fine. But It works fine at first time. does not work on the second time.

Any help will be appreciated.

EDIT 2 (I added some code):

-(IBAction)addButtonClicked:(id)sender
{
    leftBarButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStylePlain target:self action:@selector(pickerViewDoneClicked:)];

    [[self.navigationController.navigationBar.items objectAtIndex:0] setLeftBarButtonItem:leftBarButton];

    [self.pickerContainer setHidden:NO];
}

-(IBAction)pickerViewDoneClicked:(id)sender
{

    [[self.navigationController.navigationBar.items objectAtIndex:0] setLeftBarButtonItem:nil];
    NSLog(@"%@", self.myTextField);
    NSLog(@"old val %@", self.myTextField.text);


    // the text field on the main view.
    [self.myTextField setText: selectedText];

    NSLog(@"new val %@", self.myTextField.text);

    [self.pickerContainer setHidden:YES];
}

//in picker view source
selectedText = [pickerData objectAtIndex:row];

As I told the first time I add it works fine I can see the value on the textfield
but when I do the same action again and click done the app freezes.

I checked the reference of the textfield before after and no reference missing
I can see the new value and old value as well. but the UI freezes.

Answer 1

I was using this piece of code for padding for my text field,

UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 15, 20)];
self.myTextField.leftView = paddingView;
self.myTextField.leftViewMode = UITextFieldViewModeAlways;

I am not sure how it effects it but second time I change the text into the textfield I was getting my screen freezed.

Thanks again for any effort to help me.
