[ad_1] func pieChart(pieChart:XYPieChart!,index:Int!) ->CGFloat { let value:NSNumber = self.values[index] as NSNumber return value.doubleValue } 2 [ad_2] solved How do I re-write this code in Swift? [closed]
[ad_1] Basically, I’d say “don’t add Y if the statement is true”, but I may be misunderstanding your question, it seems quite simple. A ternary operator in the CGPointMake will take care of it: Bullets.center = CGPointMake(Airplane.center.x, Airplane.center.y + (CONDITION ? 0 : Y)); [ad_2] solved Stop an Increment [closed]

[ad_1] You need two formats. One to parse the original string. The second to generate the desired output. You are trying to parse the string with the output format. That won’t work. NSDateFormatter *formatterObj = [[NSDateFormatter alloc]init]; [formatterObj setDateFormat:@”yyyy-MM-dd HH:mm:ss ZZZ”]; NSDate *newDate = [formatterObj dateFromString:@”2013-03-04 19:12:55 +0000″]; [formatterObj setDateFormat:@”MMM dd, yyyy”]; NSString *stringDate = … Read more
[ad_1] Not the best naming convention but take a look at the following example. You declare a public property in the Questions object and access it from the controller after you initialised a new object there. You may consider declaring it readonly and set it to readwrite in the private interface extension. Questions.h #import <Foundation/Foundation.h> … Read more
[ad_1] You will need to calculate how many two-character pairs there are. From there, you can loop through the pairs and grab the substring from the original string, and start stitching together the new string with colons in between. You need to leave the colon off for the last pair. Here’s some code below, this … Read more
[ad_1] I would investigate ffmpeg, specifically libavcodec – this will allow you to convert static images in to a movie file (assuming you can get it to compile for iOS). As far as adding to the iPod library is concerned, you aint going to be able to do that – you can read from the … Read more
[ad_1] This is rough translation to Swift…no tested. // Define some colors. var darkGray: UIColor = UIColor.darkGrayColor() var lightGray: UIColor = UIColor.lightGrayColor() // Navigation bar background. UINavigationBar.appearance().barTintColor = darkGray UINavigationBar.appearance().tintColor = lightGray // Color of typed text in the search bar. var searchBarTextAttributes: [NSObject : AnyObject] = [NSForegroundColorAttributeName: lightGray, NSFontAttributeName: UIFont.systemFontOfSize(UIFont.systemFontSize())] UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).defaultTextAttributes = searchBarTextAttributes // … Read more
[ad_1] A switch statement is meant to be used in place of if else statements For example int a =4; if(a == 1) doSomething(); else if(a == 2) doSomethingElse(); else if(a == 3) BLAH(); else CaseUnaccountedFor(); Is equivalent to int a =4; switch(a) { case 1: doSomething(); break; case 2: doSomethingElse(); break; case 3: BLAH(); … Read more
[ad_1] You need to check if the key is really a string in your case. I doubt that. would have added as a comment.. but have lesser reputation, so please ignore. 2 [ad_2] solved NSString thinks it is null
[ad_1] Objective-C is very typeinsensitive, from the BOOL perspective 0, “0”, “NO”, “false, “false” and even nil is false, everything else is treated as true. That’s why NSString has a boolValue property. It just returns value != 0. Swift is a strong typed language. You have to check the type: let value : StringOrBool let … Read more
[ad_1] I assume, that you have at least some knowledge of computer programming in some other language then Objective-C. I will talk about this line, but the same problem occurs in several lines in your code if(NSInteger >= 4) You compare the type NSInteger with a number (4). I assume you want to compare a … Read more
