Bolts-iOS is a Manage task libary by Facebook and Parse.
To solved async callbacks problem like Promise Pattern.
When we need request batch use AFNetworking with bolts to manage request task.
Here is some sample code.
First use async BFTask to create request.
@property (nonatomic, strong) AFHTTPSessionManager *manager;
- (BFTask *) executeEndPointAsync :(NSString *)url parameters:(id)parameters {
BFTaskCompletionSource *BFTask = [BFTaskCompletionSource taskCompletionSource];
AFHTTPResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializer];
self.manager.responseSerializer = responseSerializer;
[self.manager GET:url parameters:parameters progress:^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//do something, save response
[BFTask setResult:responseObject];
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[BFTask setError:error];
}];
return BFTask.task;
}
And then run with executeEndPointAsync
- (void)runTask{
[[[BFTask taskWithResult:nil]continueWithBlock:^id _Nullable(BFTask * _Nonnull task) {
BFTask *subTask = [BFTask taskWithResult:nil];
for (int i = 0; i < 100; i++) {
subTask = [subTask continueWithBlock:^id(BFTask * subTask) {
if (subTask.isCancelled) {
}else if(subTask.error){
}else{
//do http request
return [self executeEndPointAsync:@"http://..." parameters:nil];
}
return nil;
}];
}
return subTask;
}]continueWithSuccessBlock:^id _Nullable(BFTask * _Nonnull task) {
NSLog(@"Success");
return nil;
}];
}
