本文介绍了按下时切换 UIButton 状态,如开关的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
-(void)setState:(id)sender
{
UIButton* button = (UIButton*)sender;
BOOL buttonBool = ([button state]==selected : YES ? NO);
[sender setSelected:buttonBool++];
}
这是我的想法,但我无法弄清楚调用功能的按钮的实际状态.任何调用此功能的按钮都应在默认状态和选定状态之间切换,以便它像开关一样工作.我只需要拥有自己的背景图形,否则我使用了开关.
this is my idea, but i cant figure out the actual state of the button calling the funktion. any button, that calls this funktion, should be toggled between default and selected-state, so that it works like a switch. i just need to have own background-graphics, else i had used a switch.
那么,谁能纠正我的想法?
so, can anyone please correct my idea ?
推荐答案
试试这个方法:
-(void)setState:(id)sender
{
UIButton* button = (UIButton*)sender;
button.selected = !button.selected;
}
