问题 hi i am migrating my app from ios 6.1 to 7, the app contains a tabbar controller, works perfectly fine on ios6, but when i run this on ios 7, 4 among the 5 tabbar items dont show the selected image, its being pretty weird as one is showing correctly while the others are not, am using storyboard, am not able to use "imageWithRenderingMode:" as i am still doing this on xcode 4.6, so i would like to rectify it in xcode 4.6 only and be able to run it on ios7, the code for the tabbarcontroller is

问题 I'm definitely missing something here. This should not be that hard. I am trying to implement the basic swipe to delete function on a list of items in a UITableView on an iPad. Everything seems to work except when the cell slides to the left there is NO delete button just empty white space. Below is what I have in the appropriate functions. - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { if (self.state == AMListMenu && [indexPath row] > 1) { return

问题 I've looked through countless SO answers on this subject and cannot find what I am looking for. I have a view I created in a xib file. It has a UITableView as a subview. I hooked up the delegate and data delegates to the controller and it works. Now, I want to load a custom cell in the UITableView - the cell needs to have a UILabel a UITextField and three UIButtons that are only visible when a condition is met. My question is simply this: Can I create a custom cell in a separate xib file with

问题 I've read through like 10 posts, but haven't found what's wrong with my implementation. This app was written in iOS 6 but updated to iOS7, so I want to offer support for both iOS6 and iOS7. But if I run an iOS7-only method on an iOS6 device, it breaks. So I thought of adding respondsToSelector, to check it has iOS7 on it, but for some reason, the if always returns false. AppDelegate.m: if ([[UINavigationBar appearance] respondsToSelector:@selector(shadowImage)]) if ([[UINavigationBar

问题 I have an UINavigationController with UINavigationBar hidden = YES. I want full screen bg for view that embedded in UINavigationController. But I get only that: http://cs616618.vk.me/v616618797/1bf0d/FEdIn0Nn4x8.jpg Is it possible to make it full screen under status bar? I achieved that with standalone view controller, but while using it in UINavigationController it becomes like on image. 回答1: Check that all your view controllers are correctly configured: The UINavigationController : The

问题 I'm dealing with an odd error around an UISplitViewController I created a library in order to deal with ViewControllers presentation and reuse code as much as possible. Within this code I instantiate ViewControllers using their storyboard IDs and I'm using to switch a ViewController with a SplitViewController. Despite it works fine in iOS 8, it crashes in iOS 7 with this error. Storyboard (<UIStoryboard: 0x7f94bb52ccd0>) doesn't contain a view controller with identifier

问题 is there a possibility to send Push Notifications to iOS Clients without the use of Apple´s Server´s?! And on the other Hand is it possible to push a whole file?! like a XML-File for example, or can you just push text messages?! Another Question, is there any way to push an xml-file to an iOS Client remotely?! 回答1: You can just push text message, sound (actually tell the system to play specific sound on a push, not the actual sound file). All these info are transferred in json format (push

问题 I'm using autolayout to correctly lay out some views inside a UICollectionViewCell. It works fine with iOS 8, but when I try to run it on iOS 7 or iOS 6, the cells appearance varies widely everytime they are laid out (sometimes I see small changes in size and positions - one or two pixels - and sometimes big changes, resulting in some pretty messed up cells). I swear I tried hard to find anyone with the same problem, but I couldn't. I didn't find any answer that could help me solve or even

问题 This worked before, unless it's been so long I'm overlooking something. When the table first shows everything looks great but if I scroll up and and down labels get duplicate content. -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ static NSString *CellIdentifier = @"CellIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ cell = [[UITableViewCell alloc] initWithStyle
