Я заполнил tableView
видом фона (градиент), к сожалению, заполнена только половина фона.
Есть идеи, как заполнить вторую половину?
Большое спасибо зазаранее!
код:
UIView* myView = [[GradientBackground alloc] initWithFrame:CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, self.view.bounds.size.width, self.view.bounds.size.height)];
myTableView.backgroundColor = [UIColor clearColor];
myTableView.backgroundView = myView;
и Gradientbackground.m
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
- (void)drawRect:(CGRect)rect
{
CGContextRef currentContext = UIGraphicsGetCurrentContext();
CGGradientRef glossGradient;
CGColorSpaceRef rgbColorspace;
size_t num_locations = 2;
CGFloat locations[2] = { 0.0, 1.0 };
CGFloat components[8] = { 25.0 / 255.0, 89.0 / 255.0, 140.0 / 255.0, 0.65, // Start color
25.0 / 255.0, 89.0 / 255.0, 140.0 / 255.0, 1.0 }; // End color
//( 25.0 / 255.0 ) green:( 89.0 / 255.0 ) blue:( 140.0 / 255.0 )
rgbColorspace = CGColorSpaceCreateDeviceRGB();
glossGradient = CGGradientCreateWithColorComponents(rgbColorspace, components, locations, num_locations);
CGRect currentBounds = self.bounds;
CGPoint topCenter = CGPointMake(CGRectGetMidX(currentBounds), 0.0f);
CGPoint midCenter = CGPointMake(CGRectGetMidX(currentBounds), CGRectGetMidY(currentBounds));
CGContextDrawLinearGradient(currentContext, glossGradient, topCenter, midCenter, 0);
CGGradientRelease(glossGradient);
CGColorSpaceRelease(rgbColorspace);
}
25.0 / 255.0, 89.0 / 255.0, 140.0 / 255.0, 1.0 }; // End color
//( 25.0 / 255.0 ) green:( 89.0 / 255.0 ) blue:( 140.0 / 255.0 )
rgbColorspace = CGColorSpaceCreateDeviceRGB();
glossGradient = CGGradientCreateWithColorComponents(rgbColorspace, components, locations, num_locations);
CGRect currentBounds = self.bounds;
CGPoint topCenter = CGPointMake(CGRectGetMidX(currentBounds), 0.0f);
CGPoint midCenter = CGPointMake(CGRectGetMidX(currentBounds), CGRectGetMidY(currentBounds));
CGContextDrawLinearGradient(currentContext, glossGradient, topCenter, midCenter, 0);
CGGradientRelease(glossGradient);
CGColorSpaceRelease(rgbColorspace);
