• Validate NSString

  - by Chris

  I am validating an NSString to ensure that the string does not contain apostrophes. The code I'm using to do this is NSCharacterSet * invalidNumberSet = [NSCharacterSet characterSetWithCharactersInString:@"'"]; NSScanner * scanner = [NSScanner scannerWithString:string]; NSString * scannerResult; [scanner setCharactersToBeSkipped:nil]; [scanner scanUpToCharactersFromSet:invalidNumberSet intoString:&scannerResult]; if(![string isEqualToString:scannerResult]) { return 2; } Returning 2 represents an error. This code works, except for the case where the string is an apostrophe. To get around this issue, I added the following code above the preceding block. if([string isEqualToString:@"'"]); { return 2; } This code is evaluating to true, regardless of the input. I need to either prevent the first block from crashing with the input of ', or get the second block to work. What am I missing?

• memory management question -- releasing an object which has to be returned

  - by ulag

  Hi, I have an NSMutableArray called playlist. This is in a method called getAllPlaylists. The code is something like this: -(NSMutableArray *)getAllPlaylists { //playlist is an instance variable playlist = [[NSMutableArray alloc] init]; //memory leak here . . //some code here which populates the playlist array [playlist addObject: object1]; . . return playlist; } The array allocation step of playlist is causing a memory leak. In such a scenario where can i release this array? Or can i avoid allocation n initialization of playlist here by doing something else?

• How to create a NSPredicate to find entries with leading numerical value?

  - by Toastor

  Hello, I'm using NSPredicates to fetch entities based on a name attribute. Creating a predicate for names beginning with letters was easy (@"name BEGINSWITH %@", searchLetter), however now I'd like to fetch all entities with a name that begins with a numerical value, or rather a non-alphabetical number. What would be the appropriate predicate expression here? Right now I don't want to get too deep into predicate programming, as this is all I need right now and time flies. So, please, don't point me to the Predicate Programming Guide, I just need that expression.. :) Thanks alot guys!

• Xcode save image to camera roll

  - by user1470914

  I am new to Xcode (using 4.3) and am not sure how to save an image to the device's camera roll. All that I have done so far is an IBAction for the button to save the image (the button resides in the top right of the navigation bar. This tutorial (http://www.youtube.com/watch?v=sSdwjQUXA2Y) is EXACTLY what I would like to be able to do but the code is too blurry to read properly. Any help would be greatly appreciated.

• Setting up an independent delegate?

  - by fuzzygoat

  Its common for the dataSource and delegate to be the same object, its also common for this object to be the viewController. In all the info/tutorials that I have seen online delegates are always setup as above. If I wanted to create my own class instead can anyone give me any pointers as to how I might do that. Where does that object get instantiated, how do you connect the dataSource and delegate items etc. I am using UITableView to test this.

• What kind of data type is this?

  - by mystify

  In an class header I have seen something like this: enum { kAudioSessionProperty_PreferredHardwareSampleRate = 'hwsr', // Float64 kAudioSessionProperty_PreferredHardwareIOBufferDuration = 'iobd' // Float32 }; Now I wonder what data type such an kAudioSessionProperty_PreferredHardwareSampleRate actually is? I mean this looks like plain old C, but in Objective-C I would write @"hwsr" if I wanted to make it a string. I want to pass such an "constant" or "enum thing" as argument to an method.

Afree both of these steps, I have to reload my scrollview. Can I do the same task by adding observer, so that it will automatically reload when any action done on button, and if yes then how?

• Configure UIDatePicker with current locations time

  - by Telkitty

  I am using UIDatePicker in my current app, here is how I set a UILabel with the date time string obtained from the UIDatePicker. -(IBAction)AddTimeEnd:(id)sender { NSDate * date = [m_DateTimePicker date]; m_DateTimeLabel.text = [date description]; } Somehow the time I have entered (EST) kept on getting converted to US time in the UILabel. Does anyone know how to fix it? I would like the time entered in UIDatePicker to be consistent with the text in the label (probably the simplest way is set the locale for the UIDatePicker to be the local timezone)?
