ios - How to toggle the visibility of buttons with a timer? -


Ive added an NSTimer that shows my rate button by setting a hidden action 

  NSMethodSignature * sgn = [Self-method sign-in selector: @Selector (Ontik :)); NSIVWocation * INV = [NSINVON orientation orientation method: sign: sgn]; [Inv setTarget: self]; [Inv setSelector: @selector (onTick :)); NSTimer * t = [NSTimer timer-defined time interval: 10.0 orientation: inv repeats: yes]; NSRunLoop * Runner = [NSRunLoop currentRunLoop]; [Runner addTimer: T-Fold mode: NSDFastRarLopPoids];

then 

  - tick on (zero): (NSTimer *) timer {_Rateapp1.hidden = NO; _ratebomb.hidden = NO; _ratelab1.hidden = NO; }

But how can I reveal the button again with yes?

Below your goal that toggle the display of the button every time the timer is off, just you Do this: 

  - Tick on (zero): (nstimer *) timer {_Rateapp1} = hidden! _Rateapp1.hidden; _ratebomb.hidden =! _ratebomb.hidden; _ratelab1.hidden =! _ratelab1.hidden; }

And you can change all your timer creation codes in the following way: 

  NSTimer * t = [NSTimer Scheduled timer with time interval: target 10.0 : Self Selector: @Selector (OnTick :) userInfo: Zero repeats: Yes];

There is no need to invite or runlop code. I also suggest that you stay in the context of the timer so that you can cancel the timer if necessary.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
