问题 Problem is to stop NSTimer, for some reason [Timer invalidate] just not working... Maybe my eyes are full of soap, but can't understand the reason why the timer didn't stop at 0, but go reverse counting -1, -2, -3 and so on...((( I'm using epoch numbers as destination date. One more thing - my button "IBAction stop" with [Timer invalidate] works just fine - when i push it in simulator timer stops... @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; Timer = [NSTimer

问题 I have this bug where the value of anImage.URL suddenly become nil. anImage is an object of class Image. There are 5 such values in an array. Somehow at least one of them have their URL turn into nil somehow. I have no idea where that thing is changed. So I set this up as categories for anImage.URL = something -(void) setURL:(NSString *)URL { [super setValue:URL forKey:NSStringFromSelector(@selector(URL))]; } And set breakpoint there. However, it becomes a problem because it simply

问题 I'm trying to set up a c++ unit testing library on my computer and figured that google's gtest would be a good fit. I am currently running mountain lion with the most recent release of xcode. I have been attempting to follow the instructions found here but am running into an intresting problem. I am opening the gtest project, building it, and even though xcode tells me that the build was successful, I cant seem to find the framework anywhere. any help on this subject would be highly

问题 Good Evening, I am trying to figure out how to count the number of days between date ranges by comparing the date ranges. For example, I have three given ranges: range_1 01/01/2001 to 01/01/2002 range_2 01/02/2002 to 01/01/2003 range_3 01/02/2003 to 01/01/2004 If I compare my_date_range 12/12/2001 to 01/05/2002 with the ranges above, the result should show that between range_1 and my_date_range there are 19 days, between range_2 and my_date_range there are 5 days, and between range_3 and my

问题 I'd like to be able to have specific code blocks such as #ifdef SOME_VARIABLE and the value of variable would be filled at project's build time if the project is being built on a specific user's machine. Is that possible? 回答1: You set the value in the "Preprocessor Macros" Build Settings. Setting "SOME_VARIABLE=${USER}" in the build settings is equivalent to #define SOME_VARIABLE "jappleseed" in your code. Then in your code you can do this: #define jappleseed 1 #define sjobs 2 #if DEV_USER ==

问题 I've discovered problem with svn tool after updating XCode to version 4.4. I receive "Abort trap: 6" message every time I try to execute any command like list, checkout, etc. For example: berec-Mac:~ berec$ /Applications/Xcode45-DP3.app/Contents/Developer/usr/bin/svn list https://source.com/mysource Abort trap: 6 Thank you in advance for advise. 回答1: Solution is here. The core of my problem was the Neon svn module. To resolve XCode's svn client I just replaced Xcode's svn binary by svn binary

问题 I am trying to add a new localization for my app for Mac OS X (Mountain Lion). I added the appropriate localizations to the project info panel and made all the .xib files localized. I also added and translated the .strings file and replaced the .xib files with the translated strings file. Then everything seemed to be working, and the interface builder showed appropriate translations for each localization xib file. However, when I actually run the app, it is shown in English, although the

问题 I'm quite confused about the new auto layout feature of xCode 4.5. Here is I want to do, By setting the storyboard, I have this portrait view set up. By using autolayout and constraints(and pins), how can I transform the layout when its flipped to landscape like this? I tried coding and changing the CGRect(size and coordinate location) of the views when its landscaped but to no avail. 回答1: NSLayoutConstraints replace the need for CGRects in Auto Layout. First, describe your layout in words.

问题 I've been happily compiling and going my merry way with Xcode 4.3.2 (IOS5.1). Now that I've taken the plunge and decided to move to Xcode 4.5 my App fails compilation in a most miserable manner. Now, I've not got past the issue with ARMV7 or anything like that yet. No. My issue is probably going to make many of you groan. But you can blame my basic ANSI C days for that. Everyone likes reusable code and I've created lots of it. BUT!!! I've not made any of this particular code into object(s)
