我试图根据选择的行删除一组子视图，但是当调用该方法时，只有第一个if语句可以正常工作，if（firstRowSelected）
子视图在第一行中标记为10及以上，第二行标记为50及以上，第三行标记为100及以上。我不明白什么是错的，因为除了一些变量之外，if体内的代码是相同的。
- (void) resetLane{
if (firstRowSelected) {
for(UIView *subview in [self.view subviews]) {
if (subview.tag >= 10 && subview.tag < 50) {
currentCardL1 = 10;
sipLabel.text = [NSString stringWithFormat:@"Sips: %d", sipCount];
[UIView animateWithDuration:.4
delay:.1
options: UIViewAnimationOptionCurveEaseInOut
animations:^{
animationPlaying = YES;
CGRect f = CGRectMake(0, 180, 71, 96);
subview.frame = f;
}completion: ^(BOOL finished){
[subview removeFromSuperview];
sipCount += 1;
cDisplayedL1 = 0;
}];
}
}
[self dealNewCard];
}else if (secondRowSelected) {
for(UIView *subview in [self.view subviews]) {
if (subview.tag >= 50 && subview.tag < 100) {
currentCardL2 = 10;
sipLabel.text = [NSString stringWithFormat:@"Sips: %d", sipCount];
[UIView animateWithDuration:.4
delay:.1
options: UIViewAnimationOptionCurveEaseInOut
animations:^{
animationPlaying = YES;
CGRect f = CGRectMake(0, 180, 71, 96);
subview.frame = f;
}completion: ^(BOOL finished){
[subview removeFromSuperview];
sipCount += 1;
cDisplayedL2 = 0;
}];
}
}
[self dealNewCard];
}else if (thirdRowSelected) {
for(UIView *subview in [self.view subviews]) {
if (subview.tag >= 100 && subview.tag < 150) {
NSLog(@"imgage with tag %ld removed", (long)subview.tag);
currentCardL3 = 100;
sipCount += 1;
sipLabel.text = [NSString stringWithFormat:@"Sips: %d", sipCount];
[UIView animateWithDuration:.4
delay:.1
options: UIViewAnimationOptionCurveEaseInOut
animations:^{
animationPlaying = YES;
CGRect f = CGRectMake(0, 180, 71, 96);
subview.frame = f;
}completion: ^(BOOL finished){
[subview removeFromSuperview];
cDisplayedL3 = 0;
}];
}
}
[self dealNewCard];
}
