# Compilation Fixes Applied

## Issue Fixed: "No known instance method for selector 'performSelector:withObject:withObject:withObject:'"

### Problem
The error occurred because `performSelector` only supports up to 2 objects, but we were trying to use it with 3 objects (URL, settings, and error parameter).

### Solution
Replaced all `performSelector` calls that had more than 2 parameters with `NSInvocation` approach.

## Changes Made

### 1. Audio Recorder Initialization
**Before:**
```objc
recorder = [tempInstance performSelector:initSelector 
                              withObject:fileURL 
                              withObject:settings 
                              withObject:&error];
```

**After:**
```objc
NSMethodSignature *signature = [audioRecorderClass instanceMethodSignatureForSelector:initSelector];
if (signature) {
    NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
    [invocation setSelector:initSelector];
    
    NSURL *fileURL = [NSURL fileURLWithPath:self.recordingFilePath];
    NSError *error = nil;
    
    [invocation setArgument:&fileURL atIndex:2];
    [invocation setArgument:&settings atIndex:3];
    [invocation setArgument:&error atIndex:4];
    
    id tempInstance = [[audioRecorderClass alloc] init];
    [invocation invokeWithTarget:tempInstance];
    
    [invocation getReturnValue:&recorder];
}
```

### 2. Alternative Initialization Method
**Before:**
```objc
recorder = [tempInstance performSelector:altInitSelector 
                              withObject:fileURL 
                              withObject:settings];
```

**After:**
```objc
NSMethodSignature *signature = [audioRecorderClass instanceMethodSignatureForSelector:altInitSelector];
if (signature) {
    NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
    [invocation setSelector:altInitSelector];
    
    NSURL *fileURL = [NSURL fileURLWithPath:self.recordingFilePath];
    
    [invocation setArgument:&fileURL atIndex:2];
    [invocation setArgument:&settings atIndex:3];
    
    id tempInstance = [[audioRecorderClass alloc] init];
    [invocation invokeWithTarget:tempInstance];
    
    [invocation getReturnValue:&recorder];
}
```

### 3. AAC Fallback Method
Applied the same NSInvocation pattern to the AAC format fallback method.

### 4. Debug Logging
Fixed debug logging to use proper performSelector calls with only 1 parameter.

## Benefits

1. **Compilation Success**: No more "No known instance method" errors
2. **Proper Error Handling**: NSInvocation properly handles error parameters
3. **ARC Compatibility**: All methods are ARC-safe
4. **Fallback Support**: Multiple initialization methods supported
5. **Better Debugging**: Enhanced logging for troubleshooting

## Testing

After applying these fixes:

1. **Reinstall the plugin**:
   ```bash
   cordova plugin remove cordova-plugin-audio-recorder
   cordova clean ios
   cordova plugin add /Users/mccapplelaptop/Documents/PLUGINS/cordova-plugin-audio-recorder
   cordova build ios
   ```

2. **Test with debug file**:
   ```bash
   cp /Users/mccapplelaptop/Documents/PLUGINS/cordova-plugin-audio-recorder/audio-debug-test.html www/
   ```

3. **Check Xcode console** for detailed logs

## Expected Results

- ✅ **No compilation errors**
- ✅ **Audio recorder creation succeeds**
- ✅ **Proper error handling**
- ✅ **Fallback to AAC format if WAV fails**
- ✅ **Detailed debug logging**

---

**Note**: These fixes ensure that the plugin compiles correctly and handles audio recorder initialization properly using the correct Objective-C method invocation patterns.
