針對UI給的標注圖上,色值給的都是16進制的,如#ED145B,#000000等等, 那么我們在代碼中應該怎么使用這一色值呢?下面給出幾種方案以供參考!
1. 寫一個宏定義:
#define UGUColorFromRGB_0x(rgbValue) [UIColor /colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 /green:((float)((rgbValue & 0xFF00) >> 8))/255.0 /blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]使用:
moreLabel.textColor = UGUColorFromRGB_0x(0x666666);這樣就可以為該控件設置字體顏色了
2.自己寫一個轉換方法 調用
#PRagma mark - 16進制轉RGB+ (UIColor *)getColorWithHexStr:(NSString *)hexColor { if([hexColor containsString:@"#"]){ //去掉# hexColor = [hexColor substringFromIndex:1]; } unsigned int red, green, blue; NSRange range; range.length =2; range.location =0; [[NSScanner scannerWithString:[hexColor substringWithRange:range]]scanHexInt:&red]; range.location =2; [[NSScanner scannerWithString:[hexColor substringWithRange:range]]scanHexInt:&green]; range.location =4; [[NSScanner scannerWithString:[hexColor substringWithRange:range]]scanHexInt:&blue]; return [UIColor colorWithRed:(red)/255.f green:(green)/255.f blue:(blue)/255.f alpha:1.f];}調用方法:
[_protocolBtn setTitleColor:[BSDTools getColorWithHexStr:@"000000"] forState:UIControlStateNormal];這樣也是可以設置相應控件顏色的!
