Would like to know whether a directory exist or not inside my Xcode project using objective c?

Question

I have created a directory inside my project using this code

NSError * error = nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/createDirectory1"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]) 
{
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
    NSLog(@"Create a new Dir");
}
else 
{
    NSLog(@"Dir already exist");
}

now I want to check whether the directory exist or not? how can I get that through objective c code ?

Answer 1

    NSString *docPath = [NSSearchPathForDirectoriesInDomains (NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
    NSString *filePath=[NSString stringWithFormat:@"%@/createDirectory1", docPath];
    BOOL fileExists=[[NSFileManager defaultManager] fileExistsAtPath:filePath];
    if (!fileExists)
    {

    }
    else
    {
       // Your Code
    }

Answer 2

firstly,you should get the project path .you can do it like the codes bellow

NSString *getProjectPath(){
    NSString *projectPath = [NSString stringWithFormat:@"%s,__FILE__]; // your project path may have some same  prefix  to the macro __FILE__. 
    // do something 
    return projectPath;
}

then you use [[NSFileManager defaultManager] fileExistsAtPath:dataPath] check if it exist

Answer 3

BOOL fileOrDirectoryExists = [[NSFileManager defaultManager] fileExistsAtPath:dataPath];

fileExistsAtPath:dataPath method returns a Boolean value that indicates whether a file or directory exists at a specified path. you are already doing it, as remus said.
