Question

trying to convert from java to objective-c. im havin a hard time finding anything on this subject.i get error “semantic issue” cant figure it out.
here’s the code:

-(void) createColorPalatte{
for (int i=0; i<4; i++) {
    colorPalatte[i] = [self getRandomColor];
}}
-(BOOL) checkColorPalatte {
for (int i=0; i<4; i++) {
    for (int j=i+1; j<4; j++) {
        if ([getColorFroemPalatte[i]]==[getColorFromPalatte[j]] ) {
            return YES;
        }
    }
}
return NO;

}

-(void) redoColorPalatte {
while (YES==[checkColorPalatte];) {
    [createColorPalatte];
}

}

-(char) getColorFromPalatte: (int) index{
return colorPalatte[index];

}

Answer 1

You need to give the target for your method as well, i.e. which instance it is called on. And of course use : instead of [] for the arguments.

[self checkColorPalette] and [self getColorFromPalette:i]
