objective-C不支持16进制的颜色表示，需要转换成rgb表示法

iphone应用变成中，不识别16进制的表示法，需要转化成rgb表示法

-(UIColor *) getColor:(NSString *)hexColor

{

unsigned int red, green, blue;

NSRange range;

range.length =2;

range.location =0;

[[NSScannerscannerWithString:[hexColor substringWithRange:range]]scanHexInt:&red];

range.location =2;

[[NSScannerscannerWithString:[hexColor substringWithRange:range]]scanHexInt:&green];

range.location =4;

[[NSScannerscannerWithString:[hexColor substringWithRange:range]]scanHexInt:&blue];

return [UIColor colorWithRed:(float)(red/255.0f)green:(float)(green/255.0f)blue:(float)(blue/255.0f)alpha:1.0f];

}

使用方法：

[nameLabelsetTextColor:[selfgetColor:@"5E4333"]];

或者直接到网上查找颜色相对应的rgb值
