Question

How can i build a NSString variable consisting of string and float variables?

I assume i need to cast the floats to strings, but i cant see how this is done without creating alot of messy and ugly code.

I want to build something like this: String+ Float+ String+ Float

Thanks in advance.

That is not how Objective C works. In Java, you would use:

String yourString = string1 + " " + float1 + " " + string2 + " " + float2;

You cannot do the same in Objective C. To do something to the same effect, you would need:

NSString* yourString = [NSString stringWithFormat:@"%@ %f %@ %f", string1, float1, string2, float2];

This would result in the equivalent to the Java statement. %@ indicates you want to format an object into the string, and %f indicates a floating point value.

When formatting floats in an NSString, you can specify how many decimal places you want to truncate to by placing a value in between the % and f. For example, to round the first float to 2 decimal places and the second one to 5 decimal places:

NSString* yourString = [NSString stringWithFormat:@"%@ %.2f %@ %.5f", string1, float1, string2, float2];
