Displaying plist based on variable - ios

Question

I am currently displaying my plist using the code below, which works, however this seems inefficient to me and I presume there is a cleaner approach.
if ([self.title isEqual: #"How to wear a Kilt"]){
NSString *path = [[NSBundle mainBundle] pathForResource:#"wearAKilt" ofType:#"plist"];
// Load the file content and read the data into arrays
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
thumbImg = [dict objectForKey:#"thumbImg"];
stepLabel = [dict objectForKey:#"stepLabel"];
descLabel = [dict objectForKey:#"descLabel"];
}
// Find out the path of recipes.plist
else if ([self.title isEqual: #"How to tie a cravat"]){
NSString *path = [[NSBundle mainBundle] pathForResource:#"wearACravat" ofType:#"plist"];
// Load the file content and read the data into arrays
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
thumbImg = [dict objectForKey:#"thumbImg"];
stepLabel = [dict objectForKey:#"stepLabel"];
descLabel = [dict objectForKey:#"descLabel"];
}
else if ([self.title isEqual: #"How to wear a sporran"]){
NSString *path = [[NSBundle mainBundle] pathForResource:#"wearASporran" ofType:#"plist"];
// Load the file content and read the data into arrays
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
thumbImg = [dict objectForKey:#"thumbImg"];
stepLabel = [dict objectForKey:#"stepLabel"];
descLabel = [dict objectForKey:#"descLabel"];
}
I have tried using a if statement just on the *path but this (as expected) produces a undeclared identifier path error.
if ([self.title isEqual: #"How to wear a Kilt"]){
NSString *path = [[NSBundle mainBundle] pathForResource:#"wearAKilt" ofType:#"plist"];
} else if ([self.title isEqual: #"How to tie a cravat"]) {
NSString *path = [[NSBundle mainBundle] pathForResource:#"wearACravat" ofType:#"plist"];
}
Any suggestions?

You second bit of code, just do:
NSString *path;
if ([self.title isEqual: #"How to wear a Kilt"]){
path = [[NSBundle mainBundle] pathForResource:#"wearAKilt" ofType:#"plist"];
} else if ([self.title isEqual: #"How to tie a cravat"]) {
path = [[NSBundle mainBundle] pathForResource:#"wearACravat" ofType:#"plist"];
}
You could also use a dictionary to map from the incoming string to the associated file name...
e.g.
NSDicttionary *mapping = #{
#"How to wear a Kilt" : #"wearAKilt",
#"How to tie a cravat" : #"wearACravat",
};
Which could be a static definition, and should probably consider localisation. Then:
NSString *name = [mapping objectForKey:self.title];
NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:#"plist"];
