    <p>I create a custom button, because I want a gradient button. so I use this code to implement it.</p> <pre><code> @implementation CustomButton - (id)initWithFrame:(CGRect)frame { if((self = [super initWithFrame:frame])){ [self setupView]; } //[self addObserver:self forKeyPath:@"highlighted" options:0 context:nil]; return self; } - (void)awakeFromNib { [self setupView]; } # pragma mark - main - (void)setupView { self.layer.cornerRadius = 10; self.layer.borderWidth = 1.0; self.layer.borderColor = [UIColor colorWithRed:167.0/255.0 green:140.0/255.0 blue:98.0/255.0 alpha:0.25].CGColor; self.layer.shadowColor = [UIColor blackColor].CGColor; self.layer.shadowRadius = 1; [self clearHighlightView]; CAGradientLayer *gradient = [CAGradientLayer layer]; gradient.frame = self.layer.bounds; gradient.cornerRadius = 10; gradient.colors = [NSArray arrayWithObjects: (id)[UIColor colorWithWhite:1.0f alpha:0.4f].CGColor, (id)[UIColor colorWithWhite:1.0f alpha:0.2f].CGColor, (id)[UIColor colorWithWhite:0.75f alpha:0.2f].CGColor, (id)[UIColor colorWithWhite:0.4f alpha:0.2f].CGColor, (id)[UIColor colorWithWhite:1.0f alpha:0.4f].CGColor, nil]; // float height = gradient.frame.size.height; gradient.locations = [NSArray arrayWithObjects: [NSNumber numberWithFloat:0.0f], [NSNumber numberWithFloat:0.5f], [NSNumber numberWithFloat:0.5f], [NSNumber numberWithFloat:0.8f], [NSNumber numberWithFloat:1.0f], nil]; [gradient setBackgroundColor:[UIColor redColor].CGColor]; [self.layer insertSublayer:gradient atIndex:0]; } </code></pre> <p>Now the gradient has been completed. But when I press this button , there is no highlighted status on it.</p> <p>I just want when pressed its color has been deepen. Does anyone know how to implement this? Thanks</p>

    2. COI add the subclass code here. I just want when pressed the button's color can be deepen. Do I have to change the color myself. Like if the button is red, when pressed, it should be deepen. if so I have to know the components of the deepen color. Eh, I don't know how to get the RGB color. Thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
