The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
First add the long press gesture recognizer to the table view:
ReplyDeleteUILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc]
initWithTarget:self action:@selector(handleLongPress:)];
lpgr.minimumPressDuration = 2.0; //seconds
lpgr.delegate = self;
[self.myTableView addGestureRecognizer:lpgr];
[lpgr release];
Then in the gesture handler:
-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
CGPoint p = [gestureRecognizer locationInView:self.myTableView];
NSIndexPath *indexPath = [self.myTableView indexPathForRowAtPoint:p];
if (indexPath == nil)
NSLog(@"long press on table view but not on a row");
else
NSLog(@"long press on table view at row %d", indexPath.row);
}
You have to be careful with this so that it doesn't interfere with the user's normal tapping of the cell and also note that handleLongPress may fire multiple times before user lifts their finger.
Use the UITouch timestamp property in touchesBegan to launch a timer or stop it when touchesEnded got fired
ReplyDeleteLooks to be more efficient to add the recognizer directly to the cell as shown here:
