Objective-C "miscasting" a string/int using stringWithFormat and %d
- by user141146
Hi, I think this is a relatively simple question, but I don't precisely know what's happening.
I have a method that tries to build a string using NSString's stringWithFormat
It looks like this:
NSString *line1 = [NSString stringWithFormat:@"the car is %d miles away", self.ma];
In the above line "self.ma" should be an int, but in my case, I made an error and "self.ma" actually points to a NSString.
So, I understand that the line should read
NSString *line1 = [NSString stringWithFormat:@"the car is %@ miles away", self.ma];
but my question is what is the %d in the first example doing to my NSString?
If I use the debugger, I can see that in once case, "self.ma" equals "32444", but somehow the %d converts it to 1255296.
I would've guessed that the conversion of 32444 = 1255296 is some type of base-numbering conversion (hex to dec or something), but that doesn't appear to be the case.
Any idea as to what %d is doing to my string?
TIA
