int value not passing, unrecognized selector sent to instance Terminating app due to uncaught exception 'NSInvalidArgumentException' - objective-c

Question

I'm trying to pass two integer values between different files but getting a error as mentioned in title.
Error at this line: - (NSString *) lookup: (NSString *)in get:(int)dictio get1:(int)dictio1;
Error File:

}
From file to pass:
int d=0;
int d1=0;
File passed to:
#interface MaisOuiDictionary : NSObject
- (NSString *) lookup: (NSString *) in;
- (int) dic : (int) dictio;
- (int) dic1 : (int ) dictio1;
#end
- (NSString *) lookup: (NSString *)in get:(int)dictio get1:(int)dictio1;
{
// if(dictio==10 && dictio1==10)
{
NSString *rv = [self.wordsE_S objectForKey: in];
if ( !rv )
return #"*** no translation ***";
return rv;
}
// return #"**nothing**";
}
Can someone tell me where I wrong. I have tried changing all values to int * and NSInteger *, but still getting the same error.

Answer 1

You've implemented this method
- (NSString*)lookup:(NSString*)in get:(int)dictio get1:(int)diction;
...but it looks like you're trying to call this method (that has been defined in your interface)
- (NSString*)lookup:(NSString*)in;
Because the implementation of lookup: doesn't exist, you're getting an exception thrown. You need to either:
Declare lookup:get:get1: in your interface, and call that in textFieldShouldReturn: instead of lookup:
Implement lookup: in your implementation
It all boils down to you calling a method that doesn't exist. Clarification on method naming in Objective C can be found here: Method Syntax in Objective C
