daanisotropicimage's Issues

Core Graphics Drawing

A suggestion: avoid images completely, and use https://github.com/galaxas0/Core-Graphics-Additions to draw the conical gradients required for the slider. Would this increase overhead?

thumbImage not aligned when UISlider is put in UIToolbar

The slider with DAAnisotrapicImage is working perfectly but when I put the slider in a UIToolbar the thumbImage appears a bit too low. You can see an example here: https://www.dropbox.com/s/f2d37xi2i54syae/Screen%20Shot%202012-09-02%20at%2019.09.03.png

I'm not really sure that this is an issue with DAAnisotropicImage but the previous default slider that I used did not have this problem.

The code that I use to customize the UISlider view inside a MPVolumeView:

-(void) customizeSlider{
MPVolumeView *volumeView = self.volumeView;
NSArray *tempArray = volumeView.subviews;

for (id current in tempArray){
    if ([current isKindOfClass:[UISlider class]]){
        self.tempSlider = (UISlider *) current;
        self.tempSlider.frame = CGRectMake(20.0f, 180.0f, 280.0f, 40.0f);

        UIImage *stretchableFillImage = [[UIImage imageNamed:@"slider-fill"] resizableImageWithCapInsets:UIEdgeInsetsMake(0.0f, 6.0f, 0.0f, 6.0f)];
        UIImage *stretchableTrackImage = [[UIImage imageNamed:@"slider-track"] resizableImageWithCapInsets:UIEdgeInsetsMake(0.0f, 6.0f, 0.0f, 6.0f)];
        [self.tempSlider setMinimumTrackImage:stretchableFillImage forState:UIControlStateNormal];
        [self.tempSlider setMaximumTrackImage:stretchableTrackImage forState:UIControlStateNormal];

        UIImage *initialImage = [DAAnisotropicImage imageFromAccelerometerData:nil];
        [self.tempSlider setThumbImage:initialImage forState:UIControlStateNormal];
        [self.tempSlider setThumbImage:initialImage forState:UIControlStateHighlighted];

        [self.tempSlider setThumbImage:[UIImage imageNamed:@"thumbImage.png"] forState:UIControlStateNormal];

    }
}

//start updating image
[DAAnisotropicImage startAnisotropicUpdatesWithHandler:^(UIImage *image) {
    [self.tempSlider setThumbImage:image forState:UIControlStateNormal];
    [self.tempSlider  setThumbImage:image forState:UIControlStateHighlighted];
}];

[self.volumeView removeFromSuperview];
[self.view addSubview:volumeView];

}
