iOS download,parse xml in background thread

[mraheel]

Hey,

I was trying to load XML in background, but its throwing these things in console. I am using TBXML library to load/parse a file from URL.
ANd if i dont use that, theres a lag, the UI stucks up and until the file is downloaded and parsed, nothing happens. Reminded me of windows.

-(void)LoadinBack{
	
	[self performSelectorInBackground:@selector(GetData) withObject:nil];	
}

//GetData is the method that fills the array. -(void):GetData;

anyway way around this..

Most likely if you create your own autorelease pool at the start of the background method and release it at the end that will go away but without the code we can't tell for sure.

You could also do a detached thread that would allow it to run in the background, however make sure you lock the variables used so the main thread does not release the variables before they are finished in the thread.
