iOS - custom image for UISlider
提问by soleil
I want to use an image for the UISlider track. I don't want one color on the left of the thumb, and another color on the right. I just want one static image across the whole track. Possible?
我想为 UISlider 轨道使用图像。我不希望拇指左侧有一种颜色，而右侧有另一种颜色。我只想要一张贯穿整个赛道的静态图像。可能的？

For setting the image to your slider you can use the setMinimumTrackImage, setMaximumTrackImagemethods. For your requirement set both to same image.
要将图像设置为滑块，您可以使用setMinimumTrackImage、setMaximumTrackImage方法。根据您的要求，将两者设置为相同的图像。
iOS 5 and Below
iOS 5 及以下
UIImage *sliderTrackImage = [[UIImage imageNamed: @"Slider.png"] stretchableImageWithLeftCapWidth: 7 topCapHeight: 0];
[mySlider setMinimumTrackImage: sliderTrackImage forState: UIControlStateNormal];
[mySlider setMaximumTrackImage: sliderTrackImage forState: UIControlStateNormal];

[[UISlider appearance] setThumbImage:[UIImage imageNamed:@"ball.png"] forState:UIControlStateNormal];
[slider setMinimumTrackImage:[[UIImage imageNamed:@"volume_slider_oragne.png"] stretchableImageWithLeftCapWidth:0.3 topCapHeight:0.0] forState:UIControlStateNormal];
[slider setMaximumTrackImage:[[UIImage imageNamed:@"volume_strap_gry.png"] stretchableImageWithLeftCapWidth:0.3 topCapHeight:0.0] forState:UIControlStateNormal];

Just set both sides to the same image. You might want to make two separate images with the same color/pattern if you want the rounded corners on the ends.
只需将两侧设置为相同的图像。如果您想要两端的圆角，您可能需要制作两个具有相同颜色/图案的单独图像。
