使用iconfont時進行拼接字元圖示

    NSString *iconColorStr = [NSString stringWithFormat:@"0xff%@",childModel.color];

    unsigned long color = strtoul([iconColorStr UTF8String],0,16);//轉化為16進制

    self.iconLabel.textColor= UIColorFromRGB(color);

    NSString * iconStr     = [NSString stringWithFormat:@"0x%@",@"e601"];

    unichar    icon        = strtoul([iconStr UTF8String],0, 16);

    self.iconLabel.text    = [NSString stringWithCharacters:&icon length:1];
