Java string type-convert the hexadecimal literal value to the nominal value byte data tool class private static byte hexValueOf(String hex) {byte result = 0;if (hex.charAt(0) == '0' (hex.charAt(1) == 'X' || hex.charAt(1) == 'x')) {for (int i = 2; i System.out.println("

The following is a simple method that will convert a hexadecimal color (e.g. # ffcc88) into an equivalent uicolor object. - (UIColor *) colorForHex:(NSString *)hexColor {hexColor = [[hexColor stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] uppercaseString];// String should be 6 or 7 characters if it includes '#'if ([hexColor length] Notice that we had to first separate o

// Convert the hexadecimal color (HTML color value) string to uicolor + (Uicolor *) hexstringtocolor: (nsstring *) stringtoconvert { Nsstring * cstring = [[stringtoconvert stringbytrimmingcharactersinset: [nscharacterset whitespaceandnewlinecharacterset] uppercasestring]; // String shocould be 6 or 8 characters If ([cstring length] // Strip 0x if it appears If ([cstring hasprefix: @ "0x"]) cstring =

hexadecimal string to a GB character string (e.g. convert "ced2c3c741" to "we a") private string Hexstr2str (String hexstring) { System.Text.Encoding encode=system.text.encoding.getencoding ("GB2312"); Byte[] B=new byte[hexstring. LENGTH/2]; for (int i=0;i{ B[i]=convert.tobyte ("0x" + hexstring). Substring (i*2,2), 16); } return encode. GetString (b); }
