问题 I am building an app in Xcode 9 (Swift 4) and it crashes before it even loads completely. I get an error: Thread 1: Signal SIGABRT and libc++abi.dylib: terminating with uncaught exception of type NSException . How do I know which line of code is causing the error using breakpoints and debugging? Any help would be appreciated. Thanks!

Swift - Adding long press gesture recognizer in custom cell

由 百般思念 提交于 2019-12-05 04:58:37
问题 So I have a custom cell class and a xib file for my cells in my tableview, and I want to add a long press recognition to the custom cell. I tried to drag and drop the long press recognizer to the cell in the xib-file, make the file's owner the gesture's delegate, and then "drag and add" it from the document outline to the custom class swift-file. I also added the UIGestureRecognizerDelegate to the custom cell class. Now when I run the app I get a Thread 1: signal SIGABRT error, and honestly I

Weird SIGABRT (unrecognized selector sent to instance) when using UIAlertView

由 半世苍凉 提交于 2019-12-04 21:31:15
I've been bashing my head in with this one for the past half hour, so I thought I'd ask my friends from Stack Overflow for some wisdom. I've got a tab bar application with a view controller at the root, and passing off the views to other xib s. I created a custom XIB and added its view controller class ( MoreViewController ) as an External Object in Interface Builder. When I link my methods, I get a SIGABRT error when calling the method with a UIButton : Method - (IBAction)showAbout { alert = [[[UIAlertView alloc] initWithTitle:@"About" message:@"yadda yadda yadda some message" delegate:self

Difference between raise(SIGABRT) and abort() methods

由 只愿长相守 提交于 2019-12-04 04:42:12
问题 I know that both raise(SIGABRT) and abort() methods will send a SIGABRT signal to itself. But there are some difference between those 2 functions. (e.g - abort() function unblocks the SIGABRT signal where as raise(SIGABRT) does not.) What are the other differences between raise(SIGABRT) and abort() methods 回答1: The main difference it that abort() even ends the process if SIGABRT is ignored. Verbatim from man abort: If the SIGABRT signal is ignored, or caught by a handler that returns, the
