Precautions:(1) If the image is in PNG format, you can omit the suffix in the code.(2) You can give the control a tag value, and then use Viewwithtag to get the control.(3) The upper and lower left and right movement of the transform is in accordance with the vertical direction of its upper and lower border movement, that is, if you rotate the control, then the upper and lower left and right is not the traditional up and down, but oblique up and down around.(4) The transform can achieve the effe

OverviewIn the normal usage scenario, we have handled more of the intra-rectangular touch events, such as UIButton, Uicontrol. In general, the shapes of these controls, as well as the touch areas, are rectangular or rounded rectangles. But in some special scenarios we sometimes have to deal with a more demanding requirement, such as requiring the program to process only the click events of an unconventional area, such as a circle or a five-point shape

Including font color, alignment, and placeho
