Do something in the same thread of AFNetworking - ios

Question

I'm using Objective-C. We know AFNetworking is working in another thread, but what if I want to do something after internet request.
For example:
- (BOOL)checkPassword
{
self.loginPermit = NO;
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
NSDictionary *parameters = #{#"username": self.username, #"password": self.password};
[manager POST:self.URL parameters:parameters progress:nil
success:^(NSURLSessionDataTask *task, id responseObject)
{
NSDictionary *dict = (NSDictionary *)responseObject;
if ([[dict objectForKey:#"msg"] isEqualToString:#"00001"]){
self.loginPermit = YES
}
else {
self.loginPermit = NO;
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"Error: %#", error);
}];
return self.loginPermit;
}
But it will return NO every time. How can I return the value after Internet request.

Answer 1

You should use block for this.
[self checkPassword:^(BOOL loginPermit) {
if(loginPermit){
// do your stuff
}
}];
- (void)checkPassword:(void(^)(BOOL loginPermit))completion
{
BOOL loginPermit = NO;
// show indicator
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
NSDictionary *parameters = #{#"username": self.username, #"password": self.password};
[manager POST:self.URL parameters:parameters progress:nil
success:^(NSURLSessionDataTask *task, id responseObject)
{
//hide indicator
NSDictionary *dict = (NSDictionary *)responseObject;
if ([[dict objectForKey:#"msg"] isEqualToString:#"00001"]){
loginPermit = YES;
}
else {
loginPermit = NO;
}
completion (loginPermit);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"Error: %#", error);
//hide indicator
completion (loginPermit);
}];
}
