ios - How to check for True or False on Objective C BOOL variable -

i have nsobject contains several objects couple of bool variables set either "t" or "f"

i know how use them in if statement looks this.

if (mynsobject.firstbool == t) {     // stuff here } 

i cannot , not sure why, can ask if true or yes not t have looked answers on other sites struggling find hoping might able offer insight.

any appreciated.

with bool variables , properties, comparisons yes/no or true/false unnecessary. bool valid boolean expression, can go if, ternary ? :, or loop construct without additional comparisons.

you can write this:

// use bool in if if (myobj.boolpropertyone) {     // execute if boolpropertyone set true } // use bool in loop while (!myobj.boolpropertytwo) {     // execute while boolpropertytwo set false } // use bool in conditional expression int res = myobj.boolpropertythree ? 18 : 42;
