Here’s what I use: NSString * timestamp = [NSString stringWithFormat:@”%f”,[[NSDate date] timeIntervalSince1970] * 1000]; (times 1000 for milliseconds, otherwise, take that out) If You’re using it all the time, it might be nice to declare a macro #define TimeStamp [NSString stringWithFormat:@”%f”,[[NSDate date] timeIntervalSince1970] * 1000] Then Call it like this: NSString * timestamp = TimeStamp; … Read more
Are “EXC_BREAKPOINT (SIGTRAP)” exceptions caused by debugging breakpoints? No. Other way around, actually: A SIGTRAP (trace trap) will cause the debugger to break (interrupt) your program, the same way an actual breakpoint would. But that’s because the debugger always breaks on a crash, and a SIGTRAP (like several other signals) is one type of crash. … Read more
This should work: NSBundle.mainBundle().infoDictionary![“CFBundleName”] as! String infoDictionary is declared as a var infoDictionary: [NSObject : AnyObject]! so you have to unwrap it, access it as a Swift dictionary (rather than use objectForKey), and, as the result is an AnyObject, cast it. Update Swift 3 (Xcode 8 beta 2) Always better to use constants (and optionals) … Read more
If you like your code to look as good as it runs, you’ve undoubtedly used #pragma mark – and #pragma mark <name> to provide a nice visual grouping in the Xcode class dropdown list. Xcode 4 now combines these into a single #pragma mark – <name>. More on pragma mark.
NSArray * stuff = /* … */; NSString * combinedStuff = [stuff componentsJoinedByString:@”separator”]; This is the inverse of -[NSString componentsSeparatedByString:].
this is what i used: NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; [dateFormat setDateFormat:@”yyyy-MM-dd”]; NSDateFormatter *timeFormat = [[NSDateFormatter alloc] init]; [timeFormat setDateFormat:@”HH:mm:ss”]; NSDate *now = [[NSDate alloc] init]; NSString *theDate = [dateFormat stringFromDate:now]; NSString *theTime = [timeFormat stringFromDate:now]; NSLog(@”\n” “theDate: |%@| \n” “theTime: |%@| \n” , theDate, theTime); [dateFormat release]; [timeFormat release]; [now release];
setStringValue: is the way to do it. You should make sure your outlet is being set properly. (In the debugger, make sure your textfield variable is not null.)
NSString and CFStringRef are “Toll free bridged”, meaning that you can simply typecast between them. For example: CFStringRef aCFString = (CFStringRef)aNSString; works perfectly and transparently. Likewise: NSString *aNSString = (NSString *)aCFString; The previous syntax was for MRC. If you’re using ARC, the new casting syntax is as follows: NSString *aNSString = (__bridge NSString *)aCFString; works … Read more
You are needlessly complicating things. Why are you converting the date to a time interval (then the time interval to a different primitive)? Just [sharedDefaults setObject:theDate forKey:@”theDateKey”] and be done with it. NSDate is one of the “main types” supported by the PLIST format (dates, numbers, strings, data, dictionaries, and arrays), so you can just … Read more
When the unit test harness runs your code, your unit test bundle is NOT the main bundle. Even though you are running tests, not your application, your application bundle is still the main bundle. (Presumably, this prevents the code you are testing from searching the wrong bundle.) Thus, if you add a resource file to … Read more
