我这样做是为了改变UIButton
图像,这里所有“开关”是UIButton
IBOutlets
,的Objective-C:UIButton的图像不改变
-(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;
}
但有些时候(通常先按下时时间)点击时按钮图像不会改变。
我不知道,这是怎么回事,PLZ。在此引导我,thanx提前。
