IPhone, you need a blue color, like UIColor (used in text tables) # 336699

Question

I am trying to assign blue text like this in the same way

I use my own text box.

In hex color # 336699

I need to access the color of this text, I would like to use UIColor, but it seems not one.

Answer 1

UIColorneeds values ​​in RGB / 255.0f. You can find the converter here . In your case, your color is R: 51, G: 102, B: 153.

So, the code to get UIColor:

UIColor *myColor = [UIColor colorWithRed:51.0f/255.0f green:102.0f/255.0f blue:153.0f/255.0f alpha:1.0f];

Answer 2

I wrote a category for UIColor to convert hexagon colors to UIColors

+ (UIColor *)colorWithHex:(UInt32)col {
    unsigned char r, g, b;
    b = col & 0xFF;
    g = (col >> 8) & 0xFF;
    r = (col >> 16) & 0xFF;
    return [UIColor colorWithRed:(double)r/255.0f green:(double)g/255.0f blue:(double)b/255.0f alpha:1];
}

UIColor *newColor = [UIColor colorWithHex:0x336699];
