Question

I need to return a specific UIColor for a given index.
I am trying to basically store the UIColors as NSArrays

TypeColors = [[NSDictionary alloc] initWithObjectsAndKeys:

@”1″, [NSArray arrayWithObjects:[NSNumber numberWithFloat:0.5],[NSNumber numberWithFloat:0.5],[NSNumber
numberWithFloat:0.5],[NSNumber numberWithFloat:1.0], nil],

@”5″, [NSArray arrayWithObjects:[NSNumber numberWithFloat:1.0],[NSNumber
numberWithFloat:0.5],[NSNumber numberWithFloat:0.1],[NSNumber
numberWithFloat:1.0], nil]
, nil]; //nil to signify end of objects and keys.

And here I want to retrieve the UIColor back from that dictionary:

a = 5;
NSArray* colorArray = [TypeColors objectForKey:a];
UIColor* color = [UIColor colorWithRed:[colorArray objectAtIndex:0]
green:[colorArray objectAtIndex:1] blue:[colorArray objectAtIndex:2] 
alpha:[colorArray objectAtIndex:3]];

It always returns me a zero, anyone knows why?
Thanks!

Answer 1

Change it to

UIColor* color = [UIColor colorWithRed:[[colorArray objectAtIndex:0] floatValue]
green:[[colorArray objectAtIndex:1] floatValue] blue:[[colorArray objectAtIndex:2] floatValue] 
alpha:[[colorArray objectAtIndex:3] floatValue]];

The parameter to be sent there is cgfloat and not NSNumber
