问题 I've looked at a ton of posts on similar things, but none of them quite match or fix this issue. Since iOS 7, whenever I add a UIButton to a UITableViewCell or even to the footerview it works "fine", meaning it receives the target action, but it doesn't show the little highlight that normally happens as you tap a UIButton . It makes the UI look funky not showing the button react to touch. I'm pretty sure this counts as a bug in iOS7, but has anyone found a solution or could help me find one :

问题 iOS 7.1 UPDATE : Looks like the workaround for modifying the alpha channel in the UINavigationBar has been ignored in this update. Right now, the best solution seems to be to just 'deal with it' and hope that whatever color you choose can render a translucent effect. I am still looking into ways of getting around this. iOS 7.0.3 UPDATE : The GitHub library we created has been updated to slightly work around this issue when using iOS 7.0.3. Unfortunately, there is no magic formula to support

问题 I noticed that in iOS 7, UITableViewCells have a line break in the separator of the cell that iOS 6 does not have. Is there a way to get rid of this line break? Changing the separator to none and then making UIViews with the color of the separator still causes the white separator to occur regardless. 回答1: For iOS7: if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) { [self.tableView setSeparatorInset:UIEdgeInsetsZero]; } For iOS8: First configure your table view as follows

问题 I'm using auto layout constraints programmatically to layout my custom UITableView cells and I'm correctly defining the cell sizes in tableView:heightForRowAtIndexPath: It's working just fine on iOS6 and it does look fine in iOS7 as well BUT when I run the app on iOS7, here's the kind of message I see in the console: Break on objc_exception_throw to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful

问题 I'm starting new project in Xcode 5. I want to develop application using iOS SDK 7 but with deployment target iOS 5.0 . As soon as I create new project in Xcode and try to change deployment target to 5.0, I've got this message: Applications including an arm64 slice are not compatible with versions of iOS prior to 6.0 Adjust your Architectures build setting to not include arm64 in order to deploy to releases prior to iOS 6.0. So changed architectures to Standard (no 64bit). I compiles, runs

问题 I am working on an iPad app, using AutoLayout, where if the user enables a certain mode ("heads-up" mode), I want to support only portrait (or portrait upside down) orientation, and furthermore, if the device is in landscape, I'd like to automatically switch to portrait mode. In the top view controller, I have the following: - (NSUInteger) supportedInterfaceOrientations { if (self.modeHeadsUp) { return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown; } else {

问题 In my app, I am using a navigation controller. Later on in some view I am using presentViewController for showing a zoomed image. Also I am not using a Storyboard or nib. I am getting this error in iOS 7 only. It works fine in iOS 6 and earlier: Presenting view controllers on detached view controllers is discouraged 回答1: To avoid getting the warning in a push navigation, you can directly use : [self.view.window.rootViewController presentViewController:viewController animated:YES completion
