I have created a UIResponder extension with a recursive method that you can use in any UIView (which inherits from UIResponder) to find a parent view of a specific type. import UIKit extension UIResponder { /** * Returns the next responder in the responder chain cast to the given type, or * if nil, recurses … Read more
As of iOS 5 you can just use isEqual: (see comments) Try [indexPath1 compare: indexPath2] == NSOrderedSame. Maybe you found a bug in NSIndexPath. If you try to create a new NSIndexPath with a path that already exists you should get that one instead. So isEqual: probably just compares the pointers and not the actual … Read more
Almost all Objective-C objects can be compared using the isEqual: method. So, to test equality, you just need [itemCategoryIndexPath isEqual:indexPath], and you’re good to go. Now, this works because NSObject implements isEqual:, so all objects automatically have that method, but if a certain class doesn’t override it, isEqual: will just compare object pointers. In the … Read more
For an int index: NSIndexPath *path = [NSIndexPath indexPathWithIndex:index]; Creates Index of the item in node 0 to point to as per the reference. To use the indexPath in a UITableView, the more appropriate method is NSIndexPath *path = [NSIndexPath indexPathForRow:row inSection:section];
I found an answer in the console output. Use this code in the header function: func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? Do not return your headerCell, or your reusable identifier. Return the reuseIdentifier.contentView. For me it’s: return headerCell!.contentView.
You could check – numberOfSections – numberOfItemsInSection: of your UICollectionViewDataSource to see if your indexPath is a valid one. E.g. extension UICollectionView { func isValid(indexPath: IndexPath) -> Bool { guard indexPath.section < numberOfSections, indexPath.row < numberOfItems(inSection: indexPath.section) else { return false } return true } }
[(UITableViewCell *)[(UITableView *)self cellForRowAtIndexPath:nowIndex] will give you uitableviewcell. But I am not sure what exactly you are asking for! Because you have this code and still you asking how to get uitableviewcell. Some more information will help to answer you 🙂 ADD: Here is an alternate syntax that achieves the same thing without the cast. … Read more
You have implemented didDeselectRowAtIndexPath. It will be fired when the row is no longer selected. When you touch the second row, the first row is no longer selected, so [0, 1] will be shown. When you touch the first row again, the second row is now no longer selected, so [0, 0] will be shown. … Read more
Okay, nobody has given a good answer here. Inside NSIndexPath, the indexes are stored in a simple c array called “_indexes” defined as NSUInteger* and the length of the array is stored in “_length” defined as NSUInteger. The accessor “section” is an alias to “_indexes[0]” and both “item” and “row” are aliases to “_indexes[1]”. Thus … Read more
You can create an NSIndexPath using the row and section number then reload it like so: let indexPath = NSIndexPath(forRow: rowNumber, inSection: 0) tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Top) In this example, I’ve assumed that your table only has one section (i.e. 0) but you may change that value accordingly. Update for Swift 3.0: let indexPath = IndexPath(item: … Read more
