我这样做是为了改变UIButton图像,这里所有的“开关”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;
}
但有时(通常在第一次按下时)按钮图像在点击时不会改变.
我不知道,这里发生了什么,PLZ.在此提前指导我,而不是提前.

最佳答案 如果(btnimgflag1 == 1)改为简单的else语句,你能改变这个条件.因为在if部分你将btnimgflag1指定为1 btnimgflag1 = 1;.只是我的猜测,我有完全相同的问题!如果那没有帮助!! IBOutlet连接应该是问题!!
