Using NSNumber numberWithBool in Swift
Some Swift types (Int, Bool, String, ...) are automatically bridged to the corresponding Objective-C type, so you can simply write: let success = fileToExclude.setResourceValue(true, forKey: NSURLIsExcludedFromBackupKey, error: &error) (More details in Working with Cocoa Data Types.)...
NSURL returning nil for certain cases
objective-c,nsurl,nsurlsession

redirect uri causing issues when navigating to an oauth url

Swift NSURLSession App crashes on cellular data

How to pass an array in an url query parameter using nsurl in objective-c?
Create a collection and then use NSJSONSerialization to create JSON data representation. Use the resulting data as the POST data.

Can't urlencode deviceToken (Swift)
Can you pinpoint what variable is being unwrapped and returning nil? I can't see anything that would cause that, except the URL, so your error might be an invalid URL. Remember NSURL validates the string given according to a strict syntax (RFC 2396). Try this URL (without the deviceToken) and...

%2C in NSURLComponents turns to %2525252C - swift
Just do let bbox = "\(lat1),\(lat2),\(lon1),\(lon2)", so then when it gets turned into a URL, the comma converts to %2C. I removed the + because you don't need it at all, you can just string them together in one string.
How do I give inputs through NSURL [closed]
The likely answer is "You can't." There is no secret sauce that lets you generate a URL that fills in fields in a web page. If the website you are using isn't designed to prepopulate the search field with a parameter from an URL then you won't be able to...

How can I get failed URL from didFailProvisionalNavigation method
You can use NSURLErrorFailingURLStringErrorKey to replace NSErrorFailingURLStringKey. If you jump to its definition in Xcode, you will find the below discussion.

Both constants refer to the same value for backward-compatibility, but this symbol name has a better prefix....
Parsing JSON into a usable format

The trick is to declare the right type for the cast. For your data we are using [String: [[String: AnyObject]]]: a dictionary with a String as key and an array of dictionaries as value, these dictionaries have their value as AnyObject because there's several possible types. After a successful decoding,...
How do I get the data from an NSURLSession as a string?
If your problem is that it is empty outside of the task, that is because it is going out of scope after the completion block ends.

NSURLConnection and NSMutableURLRequest Authentication
A couple of thoughts: I'm surprised by the presence of reserved characters in __VIEWSTATE and __EVENTVALIDATION. Per the x-www-form-urlencoded spec, you should be percent escaping characters other than *, -, ., 0-9, A-Z, _ and a-z. My standard percent-escaping routine for POST values is: - (NSString *)percentEscapeString:(NSString *)string { NSString...

UIImageView image not returning nil but image not showing
uiimageview,uiimage,nsurl,nlog,nil
It must be that you didn't create the image view when the first time you access the view of UIViewController. Note that self.view will trigger viewDidLoad method if it is nil, but then the imageView is nil. So you'b better create the imageView in viewDidLoad method.

Remove port from NSURL
You can write code to perform normalisation. NSURL may do some for you, but I don't think it's documented to do so. Removing the port number won't necessarily work towards normalisation, but you can do it. In both cases NSURLComponents will help you to by deconstructing the URL and allowing...

Converting URL to String and back again
fileURLWithPath() is used to convert a plain file path (e.g. "/path/to/file") to an URL. Your urlString is a full URL string including the scheme, so you should use let url = NSURL(string: urlstring) to convert it back to NSURL. Example: let urlstring = "file:///Users/Me/Desktop/Doc.txt" let url = NSURL(string: urlstring) println("the...
NSURL breaking port string with colon
Actually the solution is pretty simple... just add the scheme. Something like this: NSURL *baseURL = [NSURL URLWithString:@"http://193.178.0.99:9000"]; NSString *absoluteString = [[NSURL URLWithString:@"api/whatever" relativeToURL:baseURL] absoluteString]; // Prints => http://193.178.0.99:9000/api/whatever ...

%20 is nothing but white space. Because of stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding you see space as %20. If you have whitespace at the end, use below code to remove it. NSString *string = @" this text has spaces before and after "; NSString *trimmedString = [string stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceCharacterSet]]; ...
NSURL encoding with special charecters
Refer to NSString stringByAddingPercentEscapesUsingEncoding: you should use CFURLCreateStringByAddingPercentEscapes to custom which character you want to escape. - (NSString *) urlencodeStr:(NSString *)str { return (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes( NULL, (__bridge CFStringRef) str, NULL, CFSTR("!*'();:@+$,/?%#[]"), kCFStringEncodingUTF8)); } CFSTR("!*'();:@+$,/?%#[]") contains the characters will be escaped....
