Question

I have defined a property in application delegate.h and synthesized it in delegate.m file to make it global and to assign and to get its value from entire application:

@property (strong, nonatomic) NSArray *accountsList;

In mainviewcontroller I am assigning NSArray *accounts value to this global value like this:

((VektorAppDelegate *)[UIApplication sharedApplication].delegate).accountsList = accounts;

And in pickerviewcontroller I am assigning its value to another array like:

 accountsArray = ((VektorAppDelegate *)[UIApplication sharedApplication].delegate).accountsList;

And then assign it to a picker view as:

- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {
    return [accounts count]; //Thread 1: Program received signal: "SIGABRT"
}

Now here at this point I point I get an error and my application is crashing, sometimes it works and sometimes it gives error. I am not getting what would be the issue.

I’ve got an idea… Make a method to check if both array’s are equal. So something like

if ([(Appdelegate*).....delegate.array isEqualToArray:Accountslist]) {NSLog:(@"equal")}

If it NSLog’s correctly, you’re screwed… But if it doesn’t, then it just means you aren’t correctly initializing your array.
