Contents of UITextField and UITextView to NSString
I have a UITextView and 2 UITextField set up. UITextView resigns first responder status when empty part of the screen is tapped, the same for the 2 UITextField, plus for these 2, the return key also resigns first responder status. All 3 are declared in interface.
I would like to get the contents of all of these to individual NSString and/or learn how to enter them directly into something like:
NSString *urlstr = [[NSString alloc] initWithFormat:@"http://server.com/file.php?var1=%@&var2=%@&var3=%@", *content of UITextView*, *content of UITextField*, *content of UITextField*];
This is a very basic question, i know, but i'm pretty much a novice. If i learn how to do this i'll probably be able to pick up from there.
cheers

UITextField and UITextView both have a text property that you can use to retrieve the string values. For example,
NSString *string = [NSString stringWithFormat:@"%@, %@", textField.text, textView.text];
Keep in mind you'll probably want to examine the strings to make sure they're not empty or contain invalid characters before putting them into a URL.
The accepted answer is good, I just wanted to add the following for an expanded look at grabbing text in iOS.
See the textInRange: aspect of the below code that I devised to use one function to determine the text whether it's a UITextField, UITextView or any other class that complies with the UITextInput protocol.
//handle text container object length whether it's a UITextField, UITextView et al
NSUInteger LengthOfStringInTextInput(NSObject<UITextInput> *textContainer)
{
UITextPosition *beginningOfDocument = [textContainer beginningOfDocument];
UITextPosition *endOfDocument = [textContainer endOfDocument];
UITextRange *fullTextRange = [textContainer textRangeFromPosition:beginningOfDocument
toPosition:endOfDocument];
return [textContainer textInRange:fullTextRange].length;
}
By changing the return type to NSString and removing .length you could have the functionality of the text property on any class.
