Objective-C convention to prevent “local declaration hides instance variable” warning

Question

I am using the following code ...

-(id) initWithVariableName:(NSString*)variableName withComparisonValue:(NSString*)comparisonValue {

    // super init
             


        

Answer 1

_varName = varName;

You can use just this but without the @synthesize - whenever you want to use that variable you just write _*variable name* and it eliminates the error
