Im using this constant to convert rgb to a UIColor
#define UIColorFromRGB(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]
As i use this within my
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
like so
cell.textLabel.textColor = UIColorFromRGB(colours[indexPath.row]);`
And colours is defines as :
colours = [[NSArray alloc]
initWithObjects: @[@0x808000,@0x008080,@0x9999FF,@0x008080,@0x993366,@0xFFFF99,@0xFF8080,@0x0066CC,@0x008080,@0xFF99CC,@0x3366FF,@0x99CC00,@0x969696,@0xFF9900,@0x993300] , nil ];
i get an error Invalid operands to binary expression ('id' and int) and a warning bitsmasking for introspection of Objective-C object pointers is Strongly discouraged
Any help?
i found the solution in this way:
First Intitalize array of color code in the following way:
colors = [[NSArray alloc]
initWithObjects: @"0x808000",@"0x008080",@"0x9999FF",@"0x008080",@"0x993366",@"0xFFFF99",@"0xFF8080",@"0x0066CC",@"0x008080",@"0xFF99CC",@"0x3366FF",@"0x99CC00",@"0x969696",@"0xFF9900",@"0x993300", nil ];
Second in the UITableView's CellForRowAtIndexPath method. write the following code:
NSString *colorCode = [colors objectAtIndex:indexPath.row];
// Convert Color to RGB
NSScanner *scanner2 = [NSScanner scannerWithString:colorCode];
unsigned baseColor1;
[scanner2 scanHexInt:&baseColor1];
CGFloat listviewred = ((baseColor1 & 0xFF0000) >> 16) / 255.0f;
CGFloat listviewgreen = ((baseColor1 & 0x00FF00) >> 8) / 255.0f;
CGFloat listviewblue = (baseColor1 & 0x0000FF) / 255.0f;
Give ColorCode to cell text color like below method:
Cell.textLable.textColor = [UIColor colorWithRed:listviewred green:listviewgreen blue:listviewblue alpha:1.0];
please check and let me know.
