问题 When I try to run my project through the Xcode simulator, it keeps giving me the error "Software caused connection abort". Tried restarting the simulator & Xcode, and I recently deleted the DerivedData folder as suggested in this post about broken playgrounds so that also didn't help. 回答1: QUICK FIX This is happening because you have multiple versions of Xcode installed. MacOS unfortunately only supports running one version of Xcode at a time, and it needs to know the location of the

问题 I am importing a CSV file with a date format of month/day/year (e.g. 21/01/2007). I am looping through the CSV some are working but some are coming out with the date 1 day previous with a time of 23:00? One of the dates that are not working would look like this: NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"M/d/yyyy"]; NSDate *date = [dateFormatter dateFromString:@"10/7/2007"]; but when I output the date in an NSLog it has this: NSLog(@"Date:

问题 In the 3.1 SDk, Apple added support for associated objects. However, the simulator will not compile code that includes references to objc_setAssociatedObject, objc_getAssociatedObject, et al. (Undeclared errors) Is there away around this? Can I make the iPhone simulator compile this code? I would hate to have to do all testing on the device. Update Bug Filed: rdar://7477326 回答1: A quick and dirty workaround (largely untested, may be buggy): #if TARGET_IPHONE_SIMULATOR #import <objc/runtime.h>

问题 I am trying to monitor calls from an app to my server just like Firebug does. I could not find a way to see that in iOS Simulator or in xCode. Is there a way to do that without sniffing all the traffic? If no, what tool would you suggest? 回答1: Personally, I use Charles for that kind of stuff. When enabled, it will monitor every network request, displaying extended request details, including support for SSL and various request/reponse format, like JSON, etc... You can also configure it to

问题 I installed xcode beta as I wanted to push an app to my iphone on 10.1 beta, so needed xcode beta. The xcode beta is being super flakey and I wanted to go back to xcode 8 current build.
