16進位制轉化為顏色

16進位制轉化為相應的顏色的巨集

#define UIColorFromRGB(rgbValue,A) [UIColor colorWithRed:((float)((rgbValue &0xFF0000) >> 16))/255.0 green:((float)((rgbValue &0xFF00) >> 8))/255.0 blue:((float)(rgbValue &0xFF))/255.0 alpha:A]

使用方法如下

    view.backgroundColorUIColorFromRGB(0x000000,0.2);


// color

NSMutableAttributedString

*muString = [[NSMutableAttributedStringalloc]init];

NSDictionary *oneDict = @{NSFontAttributeName:[UIFontsystemFontOfSize:11],NSForegroundColorAttributeName:UIColorFromRGB(0xff316b,1)};

NSAttributedString *textString = [[NSAttributedStringalloc]initWithString:@"改變文字後插入圖片"attributes:oneDict];

    [muString

appendAttributedString:textString];
