I have an application with In-App Purchase, that when the user buy something, download one html file into the Documents folder of my app.
Now I must check if this HTML file exists, so if true, load this HTML file, else load my default html page.
How I can do that? With NSFileManager i can't get outside of mainBundle..
Thanks to everyone can help me!

NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
ReplyDelete... gives you the path to the documents directory. The following checks if there's a file named foo.html:
NSString* foofile = [documentsPath stringByAppendingPathComponent:@"foo.html"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:foofile];
If you set up your file system differently or looking for a different way of setting up a file system and then checking if a file exists in the documents folder heres an another example. also show dynamic checking
ReplyDeletefor (int i = 0; i < numberHere; ++i){
NSFileManager* fileMgr = [NSFileManager defaultManager];
NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString* imageName = [NSString stringWithFormat:@"image-%@.png", i];
NSString* currentFile = [documentsDirectory stringByAppendingPathComponent:imageName];
BOOL fileExists = [fileMgr fileExistsAtPath:currentFile];
if (fileExists == NO){
cout << "DOESNT Exist!" << endl;
} else {
cout << "DOES Exist!" << endl;
}
}
