format not a string literal and no format arguments (not involving NSLog)

(I am new to objective c so apologies if this seems to be a simple question)

I researched the following message here

format not a string literal and no format arguments

and most of the responses involve an NSLog statement. However, my error shows up with this line 

NSString *path = [[self applicationDocumentsDirectory] stringByAppendingFormat:[NSString stringWithFormat:@"/%@", [managedObject Name]]];

I am troubleshooting a set of code and don't seem to understand why the error is occuring here. any assistance on this would be appreciated.

Solution

  • The below should fix it.

    NSString *path = [[self applicationDocumentsDirectory] stringByAppendingFormat:[NSString stringWithFormat:@"/%@", [managedObject Name]], nil];

    Alternatively 

    NSString *path = [[self applicationDocumentsDirectory] stringByAppendingFormat:@"/%@", [managedObject Name]];

    Should also do it.

    You were calling two methods that expected a format parameter, you were passing one into the [NSString stringWithFormat] but not the stringByAppendingFormat method.
