nsstring

I would like to search for an NSString in another NSString, such that the result is found even if the second one does not start with the first one, for example: eg: I have a search string "st". I look in the following records to see if any of the below contains this search string, all of them should return a good result, because all of them have "st". Restaurant stable Kirsten At the moment I am doing the following: NSComparisonResult result = [selectedString compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; This works

I am having an issue with an NSNumber variable "num" that is currently containing 0.522000003606 I looked up several other issues on stackoverflow with others having the same issue but nothing. My project is currently using ARC so I think some features are unavailable, that is, unless I disallow ARC within the class I am currently wanting to set the precision of the NSNumber. I understand NSNumberFormatter is the basic setPrecision class function I must use but I am having issues.... Everytime i use NSNumberFormatter, it spits back NULL!!! nowValue = [now objectForKey:@"value"]; // This is

Currently I'm troubled with a small understanding issue on Objective-C. As example following Aaron Hillegass's book, I'm wondering about assigning an NSString in the init method of a class a value like in this example (For people who know the book, this is used in the Person class of RaiseMan): - (id)init { if(![super init]) return nil; myString = @"New entry"; return self; } This string isn't allocated by me, so normally I shouldn't bother about releasing it. BUT! What happens in a setter-method of this string? Following the memory management rules the method should look like: - (void

I would like to compare two NSString s. If the user types "Stonehhengge", should get a "border on answer"="almost equals", because the right answer is: "Stonhenge". I would like a percentage of how much one string equals another. If "Stonhenge" is 9 letters, and the typed text contain 8 letters from "Stonhenge", but it's not equal to "Stonhenge", for example: "Stonehange" is not equal to "Stonhenge", but it's near - I'd like to know how near a match the strings are. I only know isEqual: . If you type "Stonehenge", you match and will get the right symbol. If text field's text is not equal, you

I'm having some problems with this. I want to take an NSString and convert it to an integer array of only 0,1 values that would represent the binary equivalent of an ascii string. So for example say I have the following NSString *string = @"A"; // Decimal value 65 I want to end up with the array int binary[8] = {0,1,0,0,0,0,0,1}; then given that I have the binary integer array, how do I go back to an NSString? I know that NSString stores characters as multiple bytes but I only want to use ASCII. I tried using, NSData *data = [myString dataUsingEncoding:NSASCIIStringEncoding
