uitableview

问题 I have to create a UITableView using the JSON response below ( Array ). I have no code for this yet but would love some direction to how i would split this array to accommodate categories and items on all levels. { "result":{ "products":[ { "id":"4", "product_code":"PR04", "title":"Product1", "franchisee_id":"118" } ], "categories":[ { "id":"8", "name":"Category1" }, { "id":"20", "name":"Category2", "products":[ { "id":"9", "product_code":"PR07", "title":Product2, "franchisee_id":"118" } ] }

问题 Basically I want to delete row on click event of a button which is a part of that row. I can not use commit editing style because i want to perform unsubscribe and delete with same button. On click on subscribe button i want to delete that particular row. so any idea, how can i do it. 回答1: It works with following code On button click event CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.table]; NSIndexPath *indexPath = [self.table indexPathForRowAtPoint:buttonPosition];

问题 I have a weird problem in a Swift + Objective-C problem. I'm implementing a UITableView and a custom cell with a delegate in swift, but as soon as my UITableViewController assign my cell delegate to self, it crash both my app and Xcode. Yeah each time I crash my app, Xcode crash too, no matter what, but this is another problem. Here is a part of my cell enum NewsCellActionType: Int { case Vote = 0 case Comments case Time } protocol NewsCellDelegate { func newsCellDidSelectButton(cell:

问题 I have searched for and found various q/a on this error, but have not been able to find any specific help for my issue (at least that my minimal experience allows me to understand). I am loading a UIView from the app's main menu, which in turn has several button options (call it submenu). One of these goes back to the main menu without issue ( [self dismissModalViewControllerAnimated:YES]; ). Another button loads a UITableView (separate view controller), which loads fine. However, I want a

问题 I am having the weirdest of problems with a today widget on iOS. I have a simple widget with a table view like this: https://grab.edr.io/2e557aa43a34b7460b1eac44cbcaf596.png The thing is, it only responds to touches (the rows only get highlighted) when I tap one of the labels, and not the rest of the row (which is blank). This happens on both device and simulator. I am detecting touches using tableView:didSelectRowAtIndexPath:, so I am not being able to see a problem there. Here is a

问题 I'm looking to implement the same technique used by atebits in the Twitter app to achieve very fast UITableView scrolling, http://blog.atebits.com/2008/12/fast-scrolling-in-tweetie-with-uitableview/ But, due to Tweetie being purchased by Twitter, atebits has ceased to exist and the sample code has gone, along with all of the css for the site. Does anybody have a copy of the sample code or a different resource on implementing this method of drawing UITableViewCell's into one view? 回答1:

问题 i have several table views in my app. I am familiar with the usual behaviour of tables, that when you select a row and progress to a pushed view, it turnes blue, then when you go back it stays blue for a split second then fades to white, in order to notify the user of what row was just selected. This worked perfectly up until recently when i noticed it no longer did the last bit of what I described: it didn't stay blue for that split second... I have no idea why, but after reading a few
