ios - How to convert UIColor RGB Color to uint32_t Value -

how convert uicolor object uint32_t value. please let me know if 1 aware of this?

here code:

const cgfloat *components = cgcolorgetcomponents([uicolor redcolor].cgcolor);    cgfloat r = components[0];    cgfloat g = components[1];    cgfloat b = components[2];   const  uint32_t rgb = ((uint32_t)r << 16 | (uint32_t)g << 8 | (uint32_t)b); 

how pass 0xffffffff value in uint32_t?

 const uint32_t white = 0xffffffff, black = 0xff000000, transp = 0x00ffffff; 

if want convert hex-string integer value, should try this:

unsigned int outval; nsscanner* scanner = [nsscanner scannerwithstring:@"0xff000000"]; [scanner scanhexint:&outval];
