我正在创建自定义Container ViewController类,并且能够使用以下API创建5个子视图控制器并能够从一个子视图控制器移动到其他子视图:
transitionFromViewController:fromViewController
toViewController:toViewController
duration:1.0
options:0
animations:^{
}
completion:^(BOOL finished) {
}];
子视图控制器占用父视图控制器的一部分。每次用户滑动时,我都会使之前的控制器熄灭,并且控制器出现在可显示区域。
现在我在子视图控制器上有按钮,当我点击它们时,我没有获得事件或触发子视图控制器的Action方法。但是父视图控制器正在获取其按钮的回调,即使当前正在显示子视图。请问有人请尽快帮忙。添加下面的代码片段(虽然它稍微大一点,这将帮助您分析我是否在做任何错误)。它真的很紧急的请求.. plz plz帮助我..
父ViewController:
- (void) handleSwipeGestureLeft:(UISwipeGestureRecognizer *)gesture
{
if (showPopupValue) {
return;
}
NSInteger index = [arrayOfChildVCs indexOfObject:selectedViewController];
index = MIN(index+1, [arrayOfChildVCs count]-1);
UIViewController *newSubViewController = [arrayOfChildVCs objectAtIndex:index];
endFrame.origin.x = -1024;
startOfNewVCFrame.origin.x = 1024;
[self transitionFromViewController:selectedViewController toViewController:newSubViewController];
selectedViewController = newSubViewController;
}
- (void) handleSwipeGestureRight:(UISwipeGestureRecognizer *)gesture
{
if (showPopupValue) {
return;
}
NSInteger index = [arrayOfChildVCs indexOfObject:selectedViewController];
index = MAX(index-1, 0);
UIViewController *newSubViewController = [arrayOfChildVCs objectAtIndex:index];
