file exist in Document folder but not for Xcode - iphone

Question

I have a strange problem, this code check if a file exist inside document folder:
- (BOOL) checkIfFileExist:(NSString *)path {
NSArray *documentsPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [documentsPaths objectAtIndex:0];
NSString *fileDaControllere = [documentsDirectory stringByAppendingString:path];
if ([[NSFileManager defaultManager] fileExistsAtPath:fileDaControllere]) {
NSLog(#"exist");
return YES;
}
else {
NSLog(#"not exist");
return NO;
}
}
the problem is that I get alway file not exist while the file exist (in this case the path is Style.css)! where is the mistake?
The path seems to be correct:
Path: /Users/kikko/Library/Application Support/iPhone Simulator/6.0/Applications/38161AFA-2740-4BE2-9EC4-C5C6B317D270/Documents/Style.css
Here you can see the path on xcode and real path

Answer 1

The problem may be in the fact that you just append the file without with check if there is a path delimitor:
NSString *fileDaControllere = [documentsDirectory stringByAppendingString:path];
Thus you would become something like ../DocumentsStyle.css but it should be ../Documents/Style.css.
NSString has a special method for appending path components stringByAppendingPathComponent:
NSString *fileDaControllere = [documentsDirectory stringByAppendingPathComponent:path];

At the end I solved this issue, the strange think is that I don't know how I solved it,
the first problem is that I pass to checkIfFifFileExist the absolute path while I need to pass it relative path, and the the function trasform it to absolute path (my big big error), after this I think the problem is the use of "/", I delete all and rewrite all the code and I doing some test.
I copy folder from bundle:
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *folderPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"/icone"];
NSString *iconePath = [documentsDir stringByAppendingPathComponent:#"/icone"];
[[NSFileManager defaultManager] copyItemAtPath:folderPath toPath:iconePath error:nil];
Then I make the path of my image in this way:
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *imagePath = [documentsDir stringByAppendingPathComponent:self.objMateria.iconaMateria];
and now the file exist, a strange thing is that if:
self.objMateria.iconaMateria = /icona/Home/fisica.png
or
self.objMateria.iconaMateria = icona/Home/fisica.png
nothing change, I see the image, while I think that one of this has a wrong path...
