macOS initWithObjects in Objective-C 1.0

[trey5498]

arrSelections1 = [[NSArray alloc] initWithObjects: cse211djq, wei408djq, arc118djq, cse211clq, arc118clq, hubatlabclq, nrng514clq, wei408clq, tur2215clq, arcatlabbwq, b105110bwq, cse211bwq, hscmdlbwq, hubatlabbwq, lawpclabbwq, lbw3radbwq, nrnatlabbwq, tur2215bwq, weiatlabbwq, nil];

Above is the code located in the awakeFromNib() and it works just fine 2.0, however it doesnt add to the array correctly in 1.0 I am converting intel to PPC

 

[kainjow]

I don't see an issue. The only thing I would say is make sure one of those objects isn't nil, because if it is then any object after it won't be inserted into the array.

 

[trey5498]

These objects are buttons. None of them are even added to the array under 1.0

 

[kainjow]

I'd say there is something else going on. Can't really help unless you post more code.

Edit: make sure you're not using features of NSButton that are 10.5 only.

	} else {

	}
	arrSelections1 = [[NSArray alloc] initWithObjects: cse211djq, wei408djq, arc118djq, cse211clq, arc118clq, hubatlabclq, nrng514clq, wei408clq, tur2215clq, arcatlabbwq, b105110bwq, cse211bwq, hscmdlbwq, hubatlabbwq, lawpclabbwq, lbw3radbwq, nrnatlabbwq, tur2215bwq, weiatlabbwq, nil];

       for(i=0; i<[arrSelections1 count]; i++) {
		button1 = [arrSelections1 objectAtIndex:i];
                NSLog(@"%@", button1);
        }

		
}

Here is the larger chunk, I have it printing the elements of the object array to the console.

 

[lee1210]

I would add a check like:

if(cse211djq == nil) {
  NSLog("First object to add is nil, add will fail\n");
}

to see if this is the problem.

Not directly related but you should should always [super dealloc] after releasing all other objects.

- (void)dealloc
{
	//releases the arrays from memory
	[arrPRN release];
	[arrPRNint release];
	[arrSelections release];
	[arrSelections1 release];
	[B][super dealloc];[/B]	
}

 

[trey5498]

Nope, Not nil. The array just doesnt seem to have anything in it


2008-08-14 11:45:02.119 Circa Printer Installer[8223:10b] <NSButton: 0x2348d0>

That is on the first line got 19 of these.

 

[lee1210]

So on 10.3 -count on your array is 0 after you do the -initWithObjects? What if you use a NSMutableArray and -addObject for each? What about trying -initWithObjects:count: with a C array literal to see if this behaves differently? Does +arrayWithObjects behave differently?

stupid questions, need the + sigh?

 

[lee1210]

+ Indicates a class method rather than an instance method. it is called on the class, like NSArray, instead of an instance of that class.

[trey5498]

I have changed the way it prints out to the console as I messed on that code:

NSLog(@"object at %d is %d \n", i, button1);

This is of course in a for loop that will run through the array, and for some reason the object cse211djq (this is the name of a button object) is changed to 2311104. What did I mess up?

For one, use the %p format specifier to print a pointer, not %d. On some systems pointers are wider than ints.

After you change that, when does the address of it change? What was it before (nil?)?

-Lee

 

[trey5498]

It is now 0x2343c0

NSLog(@" there are %d object in the array", [arrSelections1 count]);

that yields 19 and there is 19 objects.

The objects are checkbox NSButtons

So it's fixed, then?

 

[trey5498]

in the first spot :cse211djq should be there so in the later rounds I will be using a for loop to uncheck or check the checkboxes. It yields a number when I use %d and I assume %p just gives me the address?

 

[trey5498]

This is supposed to work to all me to use a for loop to uncheck all the checkboxes. The array is all the objects connected to the checkbox buttons. How the selectall can not use the array as it seems to contain number only.

arrSelections1 = [[NSArray alloc] initWithObjects: cse211djq, wei408djq, arc118djq, cse211clq, arc118clq, hubatlabclq, nrng514clq, wei408clq, tur2215clq, arcatlabbwq, b105110bwq, cse211bwq, hscmdlbwq, hubatlabbwq, lawpclabbwq, lbw3radbwq, nrnatlabbwq, tur2215bwq, weiatlabbwq, nil];

then tried this however it crashed the program.

//in the init function
arrSelections1 = [[NSArray alloc] init];

//awakeFromNib()
arrSelections1 = [NSArray arrayWithObjects: cse211djq, wei408djq, arc118djq, cse211clq, arc118clq, hubatlabclq, nrng514clq, wei408clq, tur2215clq, arcatlabbwq, b105110bwq, cse211bwq, hscmdlbwq, hubatlabbwq, lawpclabbwq, lbw3radbwq, nrnatlabbwq, tur2215bwq, weiatlabbwq, nil];

Neither work. Both show as having 19 objects in the array, however when I print out the objects to the console it shows up as numbers not the object name (cse211djq). It works fine in objective 2.0 however I need to scale it to work with 1.0 for power pc. Any ideas where I went wrong

I'm pretty lost, so I'm going to try to get you to break this down...

All of those variables are IBOutlet's that represent buttons? When you print them, the best you'll get is their memory address with the %p format specifier. Otherwise, you'd need to send a message to invoke some method that will return something a little more useful, like the state of the buttons, to print.

[trey5498]

arrSelections contains the of the IBOutlets of the checkboxes. I need the literal names of the objects, this works perfectly in 2.0


Here is the 2.0 code. So you see in the setting of the array and the cse211djq example is the name of a checkbox outlet. I will manipulate the checkboxes with the array so I do not have to set each one long way.

- (IBAction)selectall:(id)sender 
{
	//uses the Selections1 array to select check all the checkboxes
	for(NSButton *button1 in arrSelections1) [button1 setState:NSOnState];
        //unchecks the selectall button
	[selectall setState:NSOffState];
	
}

here is the 1.0 code I think

- (IBAction)selectall:(id)sender 
{
        NSButton *button1
	//uses the Selections1 array to select check all the checkboxes
	for(i=0; i<[arrSelections1 count]; i++) {
               button1=[arrSelections1 objectAtIndex:1];
               [button1 setState:NSOnState];
               //unchecks the selectall button
	       [selectall setState:NSOffState];
         }
	
}

The array does not contain the correct names of the outlets but some strange number. As the selectall button does not work in 1.0

If you post your project I will fix it

Also why are you using global variables? That is unnecessary and just further complicates things.

Third, for(X in X) loops are ObjC-2.0 only, so remove those if you are compiling for 10.4.

There are no global variables. I pass variables from one place to another and the outlets are contained in the header file.

@end

EDIT: I had to remove some of the redundancy items to keep it able to post Just in the printer areas that have different names but the rest of the code is the same.

These are global variables:

PrnInstall * prninstall;
PrnInstall104 * prninstall104;

int i;
int tmp;
int tmp1;
NSString *stTmp;
NSButton *button; //ppc
NSButton *button1; //ppc

They should be declared in your class @interface, not inside the @implementation. Very few reasons you would ever need to declare a variable here.

Also I meant your complete project folder, because your code is dependent on your NIBs.

that is the full one

any updates on the project?

 

[trey5498]

anyone have any ideas what I did wrong with the Array? or do I need to flat out add each item line by line?
