I'm new to gesture recognizers so maybe this question sounds silly: I'm assigning tap gesture recognizers to a bunch of UIViews. In the method is it possible to find out which of them was tapped somehow or do I need to find it out using the point that was tapped on screen?
for (NSUInteger i=0; i<42; i++) {
float xMultiplier=(i)%6;
float yMultiplier= (i)/6;
float xPos=xMultiplier*imageWidth;
float yPos=1+UA_TOP_WHITE+UA_TOP_BAR_HEIGHT+yMultiplier*imageHeight;
UIView *greyRect=[[UIView alloc]initWithFrame:CGRectMake(xPos, yPos, imageWidth, imageHeight)];
[greyRect setBackgroundColor:UA_NAV_CTRL_COLOR];
greyRect.layer.borderColor=[UA_NAV_BAR_COLOR CGColor];
greyRect.layer.borderWidth=1.0f;
greyRect.userInteractionEnabled=YES;
[greyGridArray addObject:greyRect];
[self.view addSubview:greyRect];
NSLog(@"greyGrid: %i: %@", i, greyRect);
//make them touchable
UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter)];
letterTapRecognizer.numberOfTapsRequired = 1;
[greyRect addGestureRecognizer:letterTapRecognizer];
}
Define your target selector(highlightLetter:
) with argument as
UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter:)];
Then you can get view by
- (void)highlightLetter:(UITapGestureRecognizer*)sender {
UIView *view = sender.view;
NSLog(@"%d", view.tag);//By tag, you can find out where you had tapped.
}
