UIWebView in multithread ViewController
- by Tao
I have a UIWebView in a viewcontroller, which has two methods as below. The question is if I pop out(tap back on navigation bar) this controller before the second thread is done, the app will crash after [super dealloc], because "Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread.". Any help would be really appreciated.
-(void)viewDidAppear:(BOOL)animated {
[super viewWillAppear:animated];
NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(load) object:nil];
[operationQueue addOperation:operation];
[operation release];
}
-(void)load {
[NSThread sleepForTimeInterval:5];
[self performSelectorOnMainThread:@selector(done) withObject:nil waitUntilDone:NO];
}
