macOS Working with NSThreads

[Samppaa]

Hey I am making application where the program constantly downloads webpage in background and compares it to the old one, so I need thread for this I did this to my function where it starts getting the webpage [self performSelectorInBackgroundselector(testFunction) withObject:nil];

Yes, it keeps running the function, but I get error in console

Here is the test function

-(void)testFunction
{
    int i = 0;
    while(true) {
         [statusText setIntValue:i];
         i++;
    }
}

I get this error

Did you read the Threading Programming Guide? Specifically the Writing Your Thread Entry Routine? The very first thing it tells you to do in a new thread (create an auto release pool) solves your issue.

I read the guide abit but I missed the autorelease pool part, thanks so much! Thread programming is so easy in cocoa I love this.

The second thing it'll tell you is: never change the UI from within a thread. Which is likely the next issue you'll run into
