I'm using ARC and getting a warning saying Capturing 'request' strongly in this block is likely to a retain cycle.
__block ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:url];
[request setCompletionBlock:^{
NSString *responseString = [request responseString];
self.appointmentArray = [responseString JSONValue];
}];
[request setFailedBlock:^{
NSError *error = [request error];
NSLog(@"%@", error.description);
}];
I'm assuming request
is declared somewhere before the blocks. You need to declare it as __weak
, or set a second, weakly-declared variable to it.
This question is similar. Try this:
__block ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:url];
__weak ASIHTTPRequest *request_b = request;
[request setCompletionBlock:^{
NSString *responseString = [request_b responseString];
self.appointmentArray = [responseString JSONValue];
}];
[request setFailedBlock:^{
NSError *error = [request_b error];
NSLog(@"%@", error.description);
}];
Simply replacing:
__block ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:url];
with:
__weak ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:url];
will suffice.
