customSlider = [[UISlider alloc] initWithFrame:frame];
[customSlider addTarget:self action:@selector(sliderAction:) forControlEvents:UIControlEventValueChanged];
// in case the parent view draws with a custom color or gradient, use a transparent color
customSlider.backgroundColor = [UIColor clearColor];    
UIImage *stetchLeftTrack = [[UIImage imageNamed:@"orangeslide.png"]
                            stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
UIImage *stetchRightTrack = [[UIImage imageNamed:@"yellowslide.png"]
                             stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
[customSlider setThumbImage: [UIImage imageNamed:@"slider_ball.png"] forState:UIControlStateNormal];
[customSlider setMinimumTrackImage:stetchLeftTrack forState:UIControlStateNormal];
[customSlider setMaximumTrackImage:stetchRightTrack forState:UIControlStateNormal];
customSlider.minimumValue = 0.0;
customSlider.maximumValue = 100.0;
customSlider.continuous = YES;
customSlider.value = 50.0;

// Add an accessibility label that describes the slider.
[customSlider setAccessibilityLabel:NSLocalizedString(@"CustomSlider", @"")];
[self.view addSubview:customSlider];
customSlider.tag = 1;

Try this

CGRect frame = *youe required frame*;
UISlider * customSlider = [[UISlider alloc] initWithFrame:frame];

// in case the parent view draws with a custom color or gradient, use a transparent color
customSlider.backgroundColor = [UIColor clearColor];    
UIImage *stetchLeftTrack = [[UIImage imageNamed:@"orangeslide.png"]
                                        stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
UIImage *stetchRightTrack = [[UIImage imageNamed:@"yellowslide.png"]
                                         stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
[customSlider setThumbImage: [UIImage imageNamed:@"slider_ball.png"] forState:UIControlStateNormal];
[customSlider setMinimumTrackImage:stetchLeftTrack forState:UIControlStateNormal];
[customSlider setMaximumTrackImage:stetchRightTrack forState:UIControlStateNormal];
customSlider.minimumValue = 0.0;
