改变表格视图使用＃iphone

Question

我试图改变文本颜色为我的单元格使用＃像你在Android的XML例如：cell.textLabel.textColor = [UIColor #E01B4C];这样我可以得到我想要的任何颜色。

干杯

Answer 1

的UIColor有没有这样的方法来转换十六进制颜色，你应该转换自己：

[UIColor colorWithRed:(float)0xe0/0xff green:(float)0x1b/0xff blue:(float)0x4c/0xff alpha:1.0]; 

Answer 2

我使用这个的getColor方法，并把hexdecimal值作为参数

cell.textLabel.textColor = [self getColor:E01B4C]; 

然后做出这个方法。

- (UIColor *) getColor: (NSString *) hexColor//method for converting hexadecimal into colors. 
    { 
     unsigned int red, green, blue;//declaring colors of unsigned int type. 

     NSRange range;//range 

     range.length = 2;//length of range. 

     range.location = 0; //location of range. 

     [[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&red];//scannig red color. 

     range.location = 2;//location of red. 

     [[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&green];//scanning green color. 

     range.location = 4;//location of green. 

     [[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&blue];//scanning blue color. 

     return [UIColor colorWithRed:(float)(red/255.0f) green:(float)(green/255.0f) blue:(float)(blue/255.0f) alpha:1.0f];//returning customized colors. 
    }
