iPhone dev Stupidity 126: private folder for images

Saving image directly to the folder: 

//I do this in the didFinishPickingImage:(UIImage *)img method

NSData* imageData = UIImageJPEGRepresentation(img, 1.0);


//save to the default 100Apple(Camera Roll) folder.   

[imageData writeToFile:@"/private/var/mobile/Media/DCIM/100APPLE/customImageFilename.jpg" atomically:NO]; 

The photos there are all named in IMG_####.JPG format.

There's also a .MISC folder which contains the thumbnail for each image.

To inspect the folder: 

NSArray *directoryContent = [[NSFileManager defaultManager] directoryContentsAtPath:@"/private/var/mobile/Media/DCIM/100APPLE/.MISC"];

for(NSString * dir in directoryContent){

NSLog(dir);

}
