You want setContentOffset:. It takes a CGPoint as and argument that you can set to what ever you want using CGPointMake, but if you wish to return to the very beginning of the collection, you can simply use CGPointZero. [collectionView setContentOffset:CGPointZero animated:YES];
Are you sure you’re not accidentally overriding – (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath? “Select” vs. “deselect” has tripped me up in the past with Xcode’s code completion.
You did an impressive amount of work in your question and were so close on your own. The problem you were having comes from this line of code where you position the bounding boxes for each frame: _characterFrames[ic].origin = CGPointMake(startOffset, lineOrigin.y); The problem with it is that you are overriding whatever offset the frame already … Read more
Starting from iOS 7 you can use textContainerInset property: Objective-C textView.textContainerInset = UIEdgeInsetsMake(0, 20, 0, 20); Swift textView.textContainerInset = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 20)
Info.plist can have your own information and if you write a value with $(AppIdentifierPrefix), it is replaced to the real app identifier prefix at building phase. So, try this: In your Info.plist, add an info about app identifier prefix. <key>AppIdentifierPrefix</key> <string>$(AppIdentifierPrefix)</string> You can then retrieve it programmatically with Objective-C: NSString *appIdentifierPrefix = [[NSBundle mainBundle] objectForInfoDictionaryKey:@”AppIdentifierPrefix”]; … Read more
As some other users here, I also had the problem that the origin of the modal view controller was not correct. After some experiments, I found a solution that worked for me: – (void)viewWillLayoutSubviews{ [super viewWillLayoutSubviews]; self.view.superview.bounds = CGRectMake(0, 0, <width>, <height>); }
I think this is because in iOS 8, alert views and action sheets are actually presented view controllers (UIAlertController). So, if you’re presenting a new view controller in response to an action from the UIAlertView, it’s being presented while the UIAlertController is being dismissed. I worked around this by delaying the presentation of the UIImagePickerController … Read more
Try this searchBar.layer.borderWidth = 1; searchBar.layer.borderColor = [[UIColor lightGrayColor] CGColor];
The mobile Safari browser doesn’t support downloading files. If Safari can display it, it will display. If you have installed other apps that can open the file, Safari will detect it for you.
I found a new solution. As of iOS 8, mobile Safari renders the PDF as an image within an HTML document inside the frame. You can then adjust the width after the PDF loads: <iframe id=”theFrame” src=”https://stackoverflow.com/questions/15480804/some.pdf” style=”height:1000px; width:100%;”></iframe> <script> document.getElementById(“theFrame”).contentWindow.onload = function() { this.document.getElementsByTagName(“img”)[0].style.width=”100%”; }; </script>
