How can i convert int64_t to NSInteger in Objective-C ?
This method returns into score an int64_t* and I need to convert it to NSInteger:
[OFHighScoreService getPreviousHighScoreLocal:score forLeaderboard:leaderboardId];
Thank you.
They should be directly compatible on a 64-bit machine (or if you build with NS_BUILD_32_LIKE_64
):
NSInteger i = *score;
The documentation indicates that the definition of NSInteger
looks like this:
#if __LP64__ || TARGET_OS_EMBEDDED || TARGET_OS_IPHONE || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64
typedef long NSInteger;
#else
typedef int NSInteger;
#endif
So on a 32-bit machine you might have some truncation issues to deal with. On my machine here, this statement:
NSLog(@"%d %d", sizeof(int64_t), sizeof(NSInteger));
gives this output:
