当我制作自定义滑块时，一切正常。因为我有一个宽度和高度为 30x70 的拇指图像。但是当我实现图像时，它会自行改变方向并以 70x30 显示。
I tried changing the image also but the Thumb slider comes in 70x30. I want to show image in vertical but it displays in horizontal in UISlider.

If you want change UISlider appearance then use below method
[[UISlider appearance] setThumbImage:[UIImage imageNamed:@"slider.png"]
forState:UIControlStateNormal];
