How to retrieve sequence<float> in ObjC?
Sorry for spamming the forum, I'm really new to this and need heavy help...
So I'm trying to return a sequence<float> from server (cpp) to client (objc), and I'm stuck in how to decode the returned NSData. What I'm trying to do is:
but the returned message is not what I am expecting. Can anyone help me look at it? Thanks a lot!

NSMutableArray someArray... //Initialize someArray for (int i = 0; i < seq.length; i+=(int)sizeof(float)) { float f; NSString * s = [NSString stringWithFormat: @"{%d, %d}", i, i+(int)sizeof(float)-1]; [seq getBytes:&f range:NSRangeFromString(s)]; NSNumber * num = [NSNumber numberWithFloat:f]; [someArray addObject:num]; }
but the returned message is not what I am expecting. Can anyone help me look at it? Thanks a lot!

Hi,
See the examples from the Ice manual here. For floats, it's the same thing as for ints:NSMutableArray someArray = [NSMutableArray array]; const ICEFloat *p = (const ICEFloat *)[seq bytes]; int limit = [is length] / sizeof(ICEFloat); int i; for(i = 0; i < limit; ++i) { [someArray addObject:[NSNumber numberWithFloat:p[i]]; }
