UIButton忽略内容模式突出显示(adjustImageWhenHighlighted)

概述我使用[myButton set Image：forState：]为UIButton设置了一个UIImage; 我设置它的contentMode使用[[myButton imageView] setContentMode：UIViewContentModeScaleAspectFit]; 但是当您点击按钮时,它将返回到UIViewContentModeScaleToFill并将我的图像拉出. 使用 我使用[mybutton set Image：forState：]为UIbutton设置了一个UIImage; @H_301_2@我设置它的contentMode使用[[mybutton imageVIEw] setContentMode：UIVIEwContentModeScaleAspectFit]; @H_301_2@但是当您点击按钮时,它将返回到UIVIEwContentModeScaletoFill并将我的图像拉出.

使用adjustimageWhenHighlighted修复这个,但是然后我放宽了变暗的效果,我想保留.

有什么建议如何应付这个？
