我正在尝试更改
UIButton
的图片,这里的所有"switches"都是UIButton
的IBOutlets
。-(IBAction)userselect:(id)sender
{
UIButton *btnTagcatcher =(UIButton * )sender;
if(btnTagcatcher.tag == 1)
{
if(btnimgflag1 == 0)
{
NSString* path = [[NSBundle mainBundle] pathForResource:@"check-box-withtick-1n1"
ofType:@"png"];
UIImage *image = [[UIImage alloc] initWithContentsOfFile:path];
[switch1 setImage:image forState:UIControlStateNormal];
NSString* path1 = [[NSBundle mainBundle] pathForResource:@"check-box-withouttickn1"
ofType:@"png"];
UIImage *image1 = [[UIImage alloc] initWithContentsOfFile:path1];
[switch2 setImage:image1 forState:UIControlStateNormal];
[switch3 setImage:image1 forState:UIControlStateNormal];
[switch4 setImage:image1 forState:UIControlStateNormal];
btnimgflag2 = 0;
btnimgflag3 = 0;
btnimgflag4 = 0;
btnimgflag1 = 1;
}
else if(btnimgflag1 == 1)
{
NSString* path = [[NSBundle mainBundle] pathForResource:@"check-box-withouttickn1"
ofType:@"png"];
UIImage *image = [[UIImage alloc] initWithContentsOfFile:path];
//[switch1 setImage: image];
[switch1 setImage:image forState:UIControlStateNormal];
btnimgflag1 = 0;
}
有时候(通常是第一次按下时),按钮图像在被轻触后不会改变。
我不知道发生了什么,请指导我,谢谢。
敬礼,Saad。
