The problem is probably that that _guideDescription string already is deallocated when you try to access it in -saveIntoExisted. You are now doing _guideDescription = [[NSString alloc] initWithString:[[notification userInfo] valueForKey:@”selected”]]; and that works, but I would recommend: [_guideDescription retain]; That makes sure the system doesn’t deallocate the string. solved Program crashing after trying to read … Read more

For each set of two columns, you can use sortrows. for idx=1:2:size(M,2) M(:,idx:idx+1)=sortrows(M(:,idx:idx+1),2) end 2 solved Matlab sort every other column
The underscore matches a single character, unless it is escaped. Try: select NODE_NAME from NODES where NODE_NAME like ‘%__SQL’ escape ‘_’ 3 solved How can I use underscores in “LIKE” conditions in Tivoli? [duplicate]
The first mistake is pushing all the characters on the stack outside of the if statement. Also you should check if stack is empty before removing items from it. Otherwise EmptyStackException is thrown. // stack1.push(S.charAt(i)); <– remove this line if (S.charAt(i)!=’#’) { stack1.push(S.charAt(i)); }else if (!stack1.isEmpty()) { // <– add this check stack1.pop(); } The … Read more
What you describe in the question is not consistent with reality. Is this “renaming” not a legal thing to do? Exporting the same function under multiple names is perfectly legal. The problems you describe do not happen. Can I debug DLL with FastMM4 without changing it into a console app? Yes you can. Specify a … Read more

Well, part of the problem is that this is illegal: [UIViewControllers1.view addSubview:UIViewControllers2.view]; You must never just wantonly add one view controller’s view to another view controller’s view. There is only one way in which that is allowed outside of a built-in parent-child structure that does it for you (UINavigationController, UITabBafController, UIPageViewController), and that is when … Read more
The advantages of a named function (expression) are: makes it more reliable to call the function recursively, since the name becomes a binding inside the function itself. can create a better call stack (by using the function name instead of <anonymous> Using a named function (expression) might not be possible if you care about IE6, … Read more
