表达式结果未使用（带有数组描述）

Question

Basically, I'm trying to print out an NSArray's description.

I'm getting 'Expression Result Unused' , even though I've tried everything I could find online!

Does anyone know?

 NSArray *WalletBalance= [responseDict objectForKey:@"balance"];

 NSString *wBalance = (@"This wallet currently has %@ dollars", [WalletBalance description]);

How could I append WalletBalance's description into a string?

Answer 1

You need to use:

NSString *someText = [NSString stringWithFormat:@"This wallet currently has %@ dollars", [WalletBalance description]];
