Directory Paths on the iPhone and iPad

//The correct way to retrieve the path of the documents directory in iOS is, according to Apple Documentation:

NSArray *arrayPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [arrayPaths objectAtIndex:0];

//Objective-C class for the path of the documents directory

@interface Directories : NSObject {

}

+ (NSString*)documents;
+ (NSString*)home;
+ (NSString*)cache;
+ (NSString*)temporary;

@end


@implementation Directories

+ (NSString*)documents
{
    NSArray *arrayPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    
    NSString *docDir = [arrayPaths objectAtIndex:0];

    return docDir;
}

/* NSCachesDirectory */

+ (NSString*)temporary
{
    return NSTemporaryDirectory();
}

+ (NSString*)home
{
    return NSHomeDirectory();
}

+ (NSString*)cache
{
    NSArray *arrayPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
    
    NSString *cacheDir = [arrayPaths objectAtIndex:0];
    
    return cacheDir;
}


@end

//A simple usage example would be:

NSString* docs = [Directories documents];
NSString* filename = [docs stringByAppendingPathComponent:@"MyFileName.txt"];
