UINavigationBar Back Button does not respond to UIViewController

Hi All,
I am using Three UIViewController in My Application, which has two Buttons at the bottom.
1.On load The FirstViewController loads data from an XML feed into an UITableView. When i Click on this cell, i call the SecondViewController inside didSelectRowAtIndexPath. For this i use the Pushviewcontroller and popviewController methods.
2.Then i click on Back button to go back to previous Controller (i.e. FirstViewController).
3. When i click on the second Button on the bottom it takes to ThirdViewController, After viewing the data of it i click on another bottom button which loads the FirstViewController.
4. Now i am repeating step:1 . This time the FirstViewController calls the secondViewController using pushviewController method. but it does not respond to step:2 i.e. the popviewcontroller method does not respond.
is there any other method for using back functionality of UINavigationBar. Please help me in solving out this issue. Thanks For your help in Advance.

If I turn off the "Use a secure HTTPS connection when available." setting in the google search settings, then the problem goes away...

Iphone 5 home button does not respond, brightness reduces by itself, wont charge and its one week since i got it!

one week since i got the iphone 5: screen blacks out, when i finally get it to light up the light brightness turns low.
problems charging phone, just doesnt want to charge unless i reset the phone.
the main home button does not respond at times, approx 3-5 times a day this occurs
phones touch screen does not respond at times...whole touch screen, no response!
signal always drops out, this could be a network issue though i doubt it.
speaking to quite a few peopl i know, they are havng the same issues with there 5 but not as often as myself.
if i knew the 5 had so many issues i would not have chosen it, the 4s was fine!

Then take it back! If you've only had it for a week, you still have 51 weeks of warranty. If you are in the USA, you are also within your 14 day unconditional return for full refund period. If it has that many problems, just return it and get another one, or get your money back and buy something else. There is no reason to live with a faulty device after just one week.

I have 2 people in my contacts that I'm unable to text. The SEND button does not respond

I Have 2 contacts that I'm unable to text to. The SEND button does not respond. Other contacts will send message.

Hi Gaylene1949,
So the issue is isolated to two contacts only.
There are a couple sections in this article for troubleshooting contact specific issues.
iOS: Troubleshooting Messages
If you still can't send or receive an iMessage, follow these steps
Make sure that the contact trying to message you isn't blocked in Settings > Messages > Blocked.
Make sure that the contact you're trying to send a message to is registered with iMessage.
If the issue occurs with a specific contact or contacts, back up or forward important messages and delete your current messaging threads with the contact. Create a new message to the contact and try again.
If the issue occurs with a specific contact or contacts, delete and recreate the contact in the Contacts app. Create a new message to the newly created contact and try again.
and
If you still can't send or receive SMS, follow these steps
Make sure that the contact who's trying to message you isn't blocked in Settings > Messages > Blocked.
Make sure that you're using the area code with the contact's phone number. When sending messages internationally, you also need to use the contact's international code.
If you're using a "Pay as you go" SMS plan, make sure it has enough available balance. Contact your carrier if you're unsure of your SMS plan or the available balance.
If the issue occurs with a specific contact or contacts, back up or forward important messages and delete your current messaging threads with the contact. Create a new message to the contact and try again.
If the issue occurs with a specific contact or contacts, delete and recreate the contact from the Contacts app. Send a new message to the contact.

Button does not respond (with attachment)

Hi,
I'm trying to develop a LV program for a psychology experiment to record a participants mouse movements whilst drawing or tracing a picture using the mouse.
My program uses an event structure to generate an event each time the mouse is moved or the mouse button is pressed or released. Upon each of these events the coordinates and button position is recorded to an array.
When they have finished drawing there is a button "Stop & Save" that allows the user to save the coordinate data to a file. This can then be opened by a sister program I'm developing that allows the movements to be replayed and shows where the mouse button was down and up.
At the start of the program there is the option of loading a background jpeg picture to trace over on the screen.
The program then waits for a 'Record' button to be pressed before moving on to record all coordinates there after until the 'Stop & Save' button is pressed.
The problem I have is that the record button does not respond. It doesn't even change state when pressed, even though at that stage it's just sat in a while loop waiting for it to be pressed before moving on to the event structure.
I attach the program for you to look at.
Any help/hints much appreciated.
Thanks,
Dave.

Your overall program design is higly flawed. This calls for a single state machine with an event structure that handles all FP events. All your locals can be handled by shift regsters. Get rid of that useless stacked sequence!
Frame 0: Initialization belongs to the left of the state machine. CoordinatesArray should initialize a shift register (no locals needed). Use a boolean shift register to set state to either recording or not. Event for "record, value changed" will switch the boolean to be used on the other states.
Frame 1: "Clear" and "stop" need to be inside their own events. Running it parallel to the event structure is a no-no! Do you really want to record mouse movements on the entire FP or only on the picture area?
Frame 2: Why waste an entire frame on this? Here you clear it and in the next frame you prepend the cleared string to your data. Makes no sense.
Frame 3: An autoindexing FOR loop would be the right choice. A single formating operation can handle multiple values.
Frame 4: Writing the "coordinate string" seems useless, since you just cleared it two frame earlier. You are writing an empty string to a file! Right? Why invert the "canceled?" output, just swap the cases instead.
Frame 5: Unecessary! Once the VI runs out of code, the VI will stop automatically. The "stop" function also does not "close the program window" as you seem to indicate with a diagram comment. Check the online help.

Hi, thanks for your reply.
The reason for the main stacked sequence was to get some order to the program, my programming background's text based and as such I like to think of a program running in a list/sequence order. LabView seems strange when you've been used to programming in asm or C. Does anyone know of any books or online documentation for people migrating from text languages to LV? - I haven't found any.
"Frame 2: Why waste an entire frame on this? Here you clear it and in the next frame you prepend the cleared string to your data. Makes sense."
- The string 'CoordsArray' is cleared to make sure it's empty before chars concatanated to it in the next frame. Call me old fashioned but is it not good practice to clear out any junk in a variable rather than just assuming it's empty?
"Frame 3: An autoindexing FOR loop would be the right choice. A single formating operation can handle multiple values." - not sure what you mean by that?
"Frame 4: Writing the "coordinate string" seems useless, since you just cleared it two frame earlier. You are writing an empty string to a file! Right? Why invert the "canceled?" output, just swap the cases instead."
- No, it's not an empty string since in the previous frame the coordinates array is converted to numbers and concatanated to it. Trust me, it generates a file with lots of data in so no way is it an empty string!!
- Yes, you could just swap the cases instead of inverting the 'canceled' output but sometimes it reads better to say 'if NOT cancelled then DO theTask, ELSE DO nothing' rather than 'if cancelled DO nothing ELSE DO theTask'. Not sure if that makes sense but I guess it's just personal prefference there.
"Frame 5: Unecessary! Once the VI runs out of code, the VI will stop automatically. The "stop" function also does not "close the program window" as you seem to indicate with a diagram comment. Check the online help."
- I wasn't sure how that one would work. I wanted the final exe version to close the program window when the program comes to the end, what's the best way to do that? In the past I think I used the 'Exit' function but this would annoyingly quit LabView at the end of each trial run whilst still in the development stage.
Thanks,
Dave.

I open a new webpage in a new tab. I then go to a link and the back button does not allow me to go back to the original webpage. Any suggestions?

I open a new webpage in a new tab. I then go to a link and the back button does not allow me to go back to the original webpage. Any suggestions?

I don't think you understood the question. I am having the exact same issue. I open a link in a new tab or window, for example: https://addons.mozilla.org/firefox/addon/backforedrop/
When the new tab opens, I click on "reviews" to open the link: https://addons.mozilla.org/en-US/firefox/addon/backforedrop/#reviews in the existing tab because I want to see the reviews for this feature. After I read the reviews, I want to go back to the main link, but the back button on my browser is greyed out, as though I was never even on the previous page. So my options are 1) Open every link I ever click on in a new tab or window, or 2) Hope the website is user friendly and attempt to navigate back to the previous page using links inserted on the current page.
You never realize how frustrating not having back button is until it happens.

The back button does not work consistently, and rarely works if I open an attachment...any ideas on fixing this?

== This happened ==
Not sure how often
== I installed firefox

Same problem here: I never had a problem with the previous versions and now I don't even get my homepage when I click Firefox. Instead, I am getting a blank screen that says "New Tab", only after I click the "Home" symbol I get my Homepage (Yahoo). The browser - back and browser forward button don't work anymore, very annoying. Normally a newer version should be an improvement but it looks like Mozilla really messed up with this "improvement". probably I am going to use Google chrome from now on.

Back button does not work and homepage does not show on startup

My back and forward buttons do not work anymore. they just show grey and I can not click on them.
Also my home page does not show when i start firefox.
I reinstalled firefox 4 and then went back to firefox 3.6.16 and have the same problem in both versions.
Not sure what to do anymore
I just found out that when I open a second window everything works fine in the second window, but it still does not work in the first window.
When I close both windows the same thing happens. The first window my home page does not show up and the back button does not work, but the second window works normal. Including my home page.

Yeah, I am having the same problem (with 4.0 and earlier versions). It is really frustrating to say the least. I never thought I'd say this, but I might have to go back to IE if FF is going to be this useless. I noticed that you have to right click (instead of left click like it works in the real world) on the backwards/forwards buttons, and that is no less frustrating since my mouses backwards/forwards buttons no longer work with this new asinine button set up.

Options OK button does not respond

Firefox 5. Tools/Options window OK button does not respond. (I changed from FF4 for same reason, among others!).
