I am writing a little app to record multiple tracks and play them back over one another. I am using the PlaybackAndRecord mode and i am routing my output to the main speakers. Problem is that the bottom microphone is still being used for input as well so now I when I record I get the output from the other tracks really loud on the new track. Here is what I have so far: audioSession = [AVAudioSession sharedInstance]; [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; OSStatus propertySetError = 0; UInt32 allowMixing = true; propertySetError = AudioSessionSetProperty

Right now I'm just trying to test my app on my phone and not deploy to the store. How are all these things related? Since I'm not trying to upload to the store, can I ignore any of them? I'm on the University Developer program. I was able to get a certificate and install it in Xcode, but builds still fail. Is solving this problem just a matter of changing the application identifier? How do I know what to put in? One thing I noticed is that in the Developer Portal I see only one App ID but it's for someone with a different name. So I guess I don't have an App ID. Do I need one if I'm just

I am reading a XML file from google weather api and parsing it using NSXMLParser. The city in question is Paris. Here is a brief xml output I get <?xml version="1.0"?> <xml_api_reply version="1"> <weather module_id="0" tab_id="0" mobile_row="0" mobile_zipped="1" row="0" section="0" ><forecast_information> <city data="Paris, Île-de-France"/> <postal_code data="Paris"/> <latitude_e6 data=""/> <longitude_e6 data=""/> ... ...

I'm trying to create a simple data entry application for the Mac (not iPhone). It has an NSTableView (inside an NSScrollView) which contains an NSTextField into which the user keys data, line by line. What I have so far is working okay, except that in order to actually be able to type anything into the text field, you have to press the 'Enter' key first. Then when you press the 'Enter' key at the end, the field leaves 'edit' mode, but the highlight just sits on the same row. Having to press 'Enter', 'down arrow', 'Enter' between each row of data entered is not very efficient. What I would

I have this Error with calling NSMakeRange method. What I'm doing wrong? #import <Foundation/Foundation.h> // NSRange range1 = NSMakeRange(12, 5); yuji When you initialize a variable outside of a function or method, you can only use constant values: you can't execute any code. Here the problem is that you're trying to execute NSMakeRange . (See the answers to this question , which is similar). The solution is to declare range1 but not assign any value to it, and then implement an +initialize method that sets the value. initialize is a class method that is invoked before any other methods are
