ios - Programmatically set UIButton action throws exception -


I removed the action defined buttons in a framework and set it in a custom method and it seems that throw exception is . Here is my expulsion and additional code: 

  [_ loginView.logInView.signUpButton removeTarget: no action: NULL forControlEvents: UIControlEventTouchUpInside]; [_loginView.logInView.signUpButton addTarget: Self-action: @selector for control (custom widget): EIControlEventTouchUpInside];

customViewMethod: 

  - (minus) Kstmwumpath {[_loginView.view Nikalnapromsepiwu]; [Self.view addSubview: _signUpView.view]; }

Here's an exception:

- [__ Anssifpshn Kstmwumisn]: unrecognized selector sent to instance 0x15691730

Given that you pass itself as a button target of another category There are, and given that button handler is trying to call the methodology at the wrong target (a NSDictionary ), it's a good bet that indicates error Himself was removed after making the goal of the button. And now some random objects are in the same storage space.

This is in your post which can be validated by implementing the dealloc method on self class code.

If so, then you know that itself is being canceled soon, then check that it has reached dealloc . You need to keep a strong context for this, so it will not be canceled too soon.

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.
