ios8

问题 I have had a simple UIView block animation that handles animating a group of text fields into view when the keyboard will show (and animate them back when the keyboard hides). This has worked fine in iOS 6 & 7, but now I'm getting incorrect behavior, and it all points to some change in UIKeyboardWillShowNotification . I set up an isolated project to test this further on a single text field, with two buttons that call exactly the same methods that are fired for the keyboard's WillShow and

问题 When I am running my project in Xcode 6, I am having many weird errors. Parse Issue - Unknown type name 'NSString' Format argument not an NSString Could not build module Foundation Could not build module QuartzCore All of these errors occur in Apple's header files such as: CAMediaTiming.h, NSObjCRuntime.h,NSZone.h,NSObject.h, CALayer.h, etc. Unfortunately, the answers in here: ios - Parse Issues in NSObjCRuntime, NSZone, and NSObject did not work for me. How do you recommend I fix these

问题 OK team, this is weird. [NSDecimalNumber integerValue] is behaving strangely. I'm sat at a breakpoint, trying to figure out why some parts of my app are broken in iOS8, and I'm looking at a variable called "timeSeconds". It appears like this in the Xcode Variables View: _timeSeconds (NSDecimalNumber *) 344.514533996581994496 But when I query it in the debugger, I see this: (lldb) p [self.timeSeconds doubleValue] (double) $14 = 344.51453399658192 (lldb) p [self.timeSeconds intValue] (int) $15

问题 I am trying to run application using xcode 6 on ios8 simulator but I am getting error "The runtime for selected device is not installed ". I have set the command line tool in preferences but no luck. Please help. 回答1: This just happened to me right after a beta update to Yosemite 10.10 and Xcode 6.6.

问题 I have been making an app in Swift but I keep getting an error in my TableViewController class. I could not find any way to fix this and kept getting this error : override func tableView(tableView: UITableView?, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { let cell : TextTableViewCell = tableView!.dequeueReusableCellWithIdentifier("Cell", forIndexPath : indexPath!) as TextTableViewCell let madan : PFObject = self.timeLineData.objectAtIndex(indexPath!.row) as PFObject

问题 With the release of iOS8 I have designed my table view with cells taking advantage of self sizing cells. But I need my tables to work in iOS7 as well. How do I do that? Is there a way to check whether self sizing cells is supported or not in runtime, or can I implement some table delegate methods in my controller which will not be called in iOS7? If I try my table with self sizing cells in iOS7 I get errors on the console like this: Unable to simultaneously satisfy constraints. Probably at

问题 We have a video streaming platform where users can broadcast a live video stream and synchronise it with a set of presentation slides. To display the broadcast on iOS we are using HTTP Live Streaming. In order to show the slide at the correct time in the stream on iOS we were listening for the qt_timedmetadataupdated event provided by Apple's Quicktime Javascript API.
