IOS off Image rendering

When you set a background picture for a button, you will find that the displayed effect is not the same as the picture given by the UI, and tends to show the picture as blue, because the image is automatically rendered in the new version of iOS.

All we have to do is turn the picture off.

-(UIImage *) Imagewithrenderingmode: (Uiimagerenderingmode) Renderingmode

This method is used to set the rendering mode of the image.

Uiimagerenderingmodealwaysoriginal This enumeration value is to declare that the picture is to be displayed as it was originally, and that it does not need to be rendered into another color

UIImage *playimage = [UIImage imagenamed:@ "Luzhi"];
Playimage = [Playimage imagewithrenderingmode:uiimagerenderingmodealwaysoriginal];
[_playbtn setimage:playimage Forstate:uicontrolstatenormal];
