RACCommand's executionSignals's subscribeNext block or error's block execute more times?

[mdiep]

You only need to call the error's subscribeNext: once. It sounds like you're calling it multiple times. Can you share some code?

sure; the view like below picture;

if the server send error like 403(cause my app don't be verified so the server limit the interface call times). And the user can did this sendBtn more times, so the errors subscribeBlock can be executed more times, as same as the command be executed more times too; Here is my code, so can i have some solution to avoid this kind of problem?

[[_sendBtn rac_signalForControlEvents:UIControlEventTouchDown] subscribeNext:^(id x) {
            
            [weakSelf.sendViewModel.sendCommand.executionSignals.switchToLatest subscribeNext:^(id x) {
                MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
                hud.mode = MBProgressHUDModeText;
                hud.labelText = @"已发送";
                [hud hide:YES afterDelay:1.0];

                dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                    [self.view endEditing:YES];
                    [self dismissViewControllerAnimated:YES completion:nil];
                });
            }];
            
            
            [weakSelf.sendViewModel.sendCommand.errors subscribeNext:^(id x) {
                LJLog(@"()()()()"); // click more times the text will be loged more times
                MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
                hud.mode = MBProgressHUDModeText;
                hud.labelText = @"新浪服务器开小差了...";
                [hud hide:YES afterDelay:1.0];
            }];
            
            NSDictionary *dict = @{@"statusd":_textView.text};
            [self.sendViewModel.sendCommand execute:dict];
        }];

You shouldn't subscribe to errors or executionSignals every time the button is pressed. It should only happen once.

            [weakSelf.sendViewModel.sendCommand.executionSignals.switchToLatest subscribeNext:^(id x) {
                MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
                hud.mode = MBProgressHUDModeText;
                hud.labelText = @"已发送";
                [hud hide:YES afterDelay:1.0];

                dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                    [self.view endEditing:YES];
                    [self dismissViewControllerAnimated:YES completion:nil];
                });
            }];
            
            
            [weakSelf.sendViewModel.sendCommand.errors subscribeNext:^(id x) {
                LJLog(@"()()()()"); // click more times the text will be loged more times
                MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
                hud.mode = MBProgressHUDModeText;
                hud.labelText = @"新浪服务器开小差了...";
                [hud hide:YES afterDelay:1.0];
            }];

[[_sendBtn rac_signalForControlEvents:UIControlEventTouchDown] subscribeNext:^(id x) {
            NSDictionary *dict = @{@"statusd":_textView.text};
            [self.sendViewModel.sendCommand execute:dict];
        }];
