How to send two float in one package OSC - ios

Question

i need to send in one package two float numbers. I use CocoaOSC project https://github.com/danieldickison/CocoaOSC
how i call function to send:
[delegate sendPacket:#"/ShotHappends" value:[NSString stringWithFormat:#"%.3f %.3f", myXRound, myYRound] type:2];
my function
- (void)sendPacket:(NSString*)address value:(NSString*)sendValue type:(int)type
{
defaults = [NSUserDefaults standardUserDefaults];
remoteHost = [defaults stringForKey:#"host"];
remotePort = [defaults stringForKey:#"port"];
NSLog(#"Value: %#", sendValue);
OSCMutableMessage *message = [[OSCMutableMessage alloc] init];
message.address = address;
sendType = type;
switch (sendType)
{
case 0: [message addString:sendValue]; break;
case 1: [message addInt:[sendValue intValue]]; break;
case 2: [message addFloat:[sendValue floatValue]]; break;
case 3: [message addBlob:[sendValue dataUsingEncoding:NSUTF8StringEncoding]]; break;
case 4: [message addTimeTag:[NSDate date]]; break;
case 5: [message addBool:YES]; break;
case 6: [message addBool:NO]; break;
case 7: [message addImpulse]; break;
case 8: [message addNull]; break;
}
[connection sendPacket:message toHost:remoteHost port:[remotePort intValue]];
}
so as you see i create a string and say in my function what is in these string, if i say that string #"0,22 0,45" is float my server will get only first number, so how can i send two floats to my server? Thank you.

I haven't tested this, or even read the API, but I would imagine you would have to create a version of your method that accepts arrays of type/values:
- (void)sendPacket:(NSString*)address
values:(NSArray*)values
types:(NSArray*)types
{
NSAssert([values count] == [types count], #"Values/types array are different sizes!");
defaults = [NSUserDefaults standardUserDefaults];
remoteHost = [defaults stringForKey:#"host"];
remotePort = [defaults stringForKey:#"port"];
OSCMutableMessage *message = [[OSCMutableMessage alloc] init];
message.address = address;
for (NSUInteger i = 0; i < [values count]; i++)
{
int sendType = [[types objectAtIndex:i] intValue];
id sendValue = [values objectAtIndex:i];
switch (sendType)
{
case 0: [message addString:sendValue]; break;
case 1: [message addInt:[sendValue intValue]]; break;
case 2: [message addFloat:[sendValue floatValue]]; break;
case 3: [message addBlob:[sendValue dataUsingEncoding:NSUTF8StringEncoding]]; break;
case 4: [message addTimeTag:[NSDate date]]; break;
case 5: [message addBool:YES]; break;
case 6: [message addBool:NO]; break;
case 7: [message addImpulse]; break;
case 8: [message addNull]; break;
}
}
[connection sendPacket:message toHost:remoteHost port:[remotePort intValue]];
}
Note: as you are passing the types (int) in an Objective-C collection class, they must be wrapped in NSNumber objects:
[delegate sendPacket:#"/ShotHappends"
values:#[[NSString stringWithFormat:#"%.3f", myXRound],
[NSString stringWithFormat:#"%.3f", myYRound]
]
types:#[ #(2), #(2) ]
];
Note 2: An improvement to your method would be to pass strings as NSString, numbers/bools as NSNumber and data as NSData rather than using NSString all the time. Up to you, though.
