ios How to know which UIView when I click from xib? - ios

Question

Because some reasons, I create a UIView xib file to reuse.
How to know which UIView when I click from xib?
I create a xib file extends UIView(named with XibView).
Then I drag two UIView(leftView,rightView) in the storyboard, and set the custom class "XibView" in XCode inspector window.
When I compile the code, It will get correct result that show two UIViews.
XibView.m file part code below:
-(id) initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithCoder:aDecoder];
if( self )
{
UIView *containerView = [[[UINib nibWithNibName:#"XibView" bundle:nil] instantiateWithOwner:self options:nil] objectAtIndex:0];
CGRect newFrame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height);
containerView.frame = newFrame;
[self addSubview:containerView];
}
return self;
}
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(#"tap in xib");
......
}
But How can I know which UIView is my click?
// I add some detail description.
In the xib custom class, I will using post the notify to the uiviewcontroller and take some data when user click in xib(touchesBegan is in the xib custom class).
I have two uiview in the storyboard , these uiview will using the xib file.
so I want to know when I click which uiview, I can know which one user click.
// ------------- answer . please refer #Boyi Li answer. ---------
In the XibView.m had add the
[super touchesBegan:touches withEvent:event];
to override the touches begain method.
and add the XibView header file in the viewcontroller.
It can drag the refer to the viewcontroller.

Answer 1

As your said, you could assign different tag for these two views. Inside XibView, you could check self.tag == <tag>.
If you want to get specific view in parent view or controller, use viewWithTag: method. It will check hierarchy whose tag property matches the value in the tag parameter.
Update:
Create IBOutlet Reference in ViewController for left and right Views. In your controller, you have:
#property (nonatomic, weak) IBOutlet XibView *leftView;
#property (nonatomic, weak) IBOutlet XibView *rightView;`
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [[event allTouches] anyObject];
CGPoint leftTouchPoint = [touch locationInView:leftView];
CGPoint rightTouchPoint = [touch locationInView:rightView];
if ([self.leftView pointInside:leftTouchPoint withEvent:event]) {
// Do something for leftView
} else if ([self.rightView pointInside:rightTouchPoint withEvent:event]) {
// Do something for Right View
}
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[super touchesBegan:touches withEvent:event];
UITouch *touch = [touches anyObject];
if ([touch.view isKindOfClass: UIView.class])
{
UIView *view=touch.view;
if (view==YourView1)
{
//start editing
}else
if (view==YourView2)
{
//start editing
}
}
else
{
}
}
