Redundant If Statement¶

This rule reports instances of unnecessary if statements that can be simplified to a single assignment or return statement.

Examples¶

- (BOOL)foo:(int)bar {
  if (bar == 1) {
    return YES;
  }
  else {
    return NO;
  }

  // can be simplified to:
  // return bar == 1;
}

- (BOOL)foo:(int)bar {
  BOOL b;
  if (bar == 1) {
    b = NO;
  }
  else {
    b = YES;
  }

  // can be simplified to:
  // b = (bar != 1);
}
