我们在用UIButton的时候,想要两张图片,一张时正常显示的,一张是在点击时显示的,这个该怎么实现呢?
下面时我的实现方式,如有别的方式,请大家一起分享出来,共同学习....
NSString *path = nil;
UIImage *image = nil;
path = [[NSBundle mainBundle] pathForResource:@"menubtn1" ofType:@"png"];
image = [UIImage imageWithContentsOfFile:path];
_gameBtn = [UIButton buttonWithType:UIButtonTypeCustom];
_gameBtn.frame = CGRectMake(180, 670, image.size.width, image.size.height);
[_gameBtn setImage:image forState:UIControlStateNormal];//这个图片是在布点击时响应
path = nil;
image = nil;
path = [[NSBundle mainBundle] pathForResource:@"menubtn1_1" ofType:@"png"];
image = [UIImage imageWithContentsOfFile:path];
[_gameBtn setImage:image forState:UIControlStateHighlighted];//图片在点击的时候响应
[_gameBtn addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:_gameBtn];
path = nil;
image = nil;
下面还有响应事件的代码:
-(IBAction)ButtonClick:(id)sender{
UIButton *whichOne = (UIButton *)sender;
if (_gameBtn == whichOne) {
NSLog(@"You Clicked _gameBtn");
}
}
