• iphone setting UITextView delegate breaks auto completion

  - by Tristan

  Hi there! I have a UITextField that I would like to enable auto completion on by: [self.textView setAutocorrectionType:UITextAutocorrectionTypeYes]; This works normally, except when I give the UITextView a delegate. When a delegate is set, auto complete just stops working. The delegate has only the following method: - (void)textViewDidChange:(UITextView *)textView { self.textView.text = [self.textView.text stringByReplacingOccurrencesOfString:@"\n" withString:@""]; int left = LENGTH_MAX -[self.textView.text length]; self.characterCountLabel.text = [NSString stringWithFormat:@"%i",abs(left)]; } Does anyone know how to have both auto complete enabled and a delegate set? Thanks!Tristan

• Hiding/ Showing UIPickerView

  - by aahrens

  I Have an a touchesEnded event that checks for when a UITextField is pressed. What I would like it to do is is hide/show a UIPickerView. How can this be done? - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; if (CGRectContainsPoint([self.textField frame], [touch locationInView:self.view])) { NSString * error = @"Touched the TextField"; UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:@"Selection!" message:error delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [errorAlert show]; //Want to show or hide UIPickerView } } I already have an allocated UIPickerView when touches occur @interface ThirdViewController : UIViewController <UITextFieldDelegate,UIPickerViewDelegate> { IBOutlet UIPickerView *pickerView; }

• MKMapView doesn't want to call didAddAnnotationViews method

  - by TheLearner

  I am writing a little map kit app but it doesn't want to call the delegate method didaddannotationviews: (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views { //Get the first MKAnnotationView from the views returned MKAnnotationView *annotationView = [views objectAtIndex:0]; //Get the annotation from the first annotation view and save it in a variable which can hold any object as long as it implements mkannotation id <MKAnnotation> mp = [annotationView annotation]; //Create a region MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance([mp coordinate], 250, 250); //As the mapview to animate i.e. display the region [mv setRegion:region animated:YES]; } @interface WhereAmIAppDelegate : NSObject { UIWindow *window; CLLocationManager *locationManager; IBOutlet MKMapView *mapView; IBOutlet UIActivityIndicatorView *activityIndicator; IBOutlet UITextField *locationTitleField; }

• Core data and special characters (UTF-8)

  - by MW

  I have an iPhone application using Core Data with an SQLite database in the bottom. I'm writing some text content from the database to a file, but special characters such as Å, Ä and Ö are corrupted in the file (they show up just fine in the application). When creating and inserting data, I am not using any special encoding. I'm just taking the NSString (entered by the user in a UITextField) and putting it in my persistent objects. When saving the file, I use the following code: [csvString writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:&error]; I tried adding a BOM to the beginning of the text ("\xef\xbb\xbf") but it is still corrupted. Anyone has any ideas where the problem might be? Examples of corrupted characters: å becomes ö, ä becomes ä

• UITextInput setMarkedText:selectedRange not working? (Can't be!)

  - by nacho4d

  I want to set the marked text programmatically and since iOS5 UITextView and UITextField conform to UITextInput this should be possible but for some reason I always get the markedText to be nil. :( What am I missing here? This is what I've tried without success: (While the textview is firstResponder) 1.- When the text view contains no text: text: "", selectedRange : {0,0}, markedText: nil. [_textView setMarkedText:@"?" selectedRange:NSMakeRange(0, 1)]; Result: text : "", selectedRange: {0,0}, markedText: nil. (Nothing changed) 2.- When the text view contains text + some marked text: text : "AAA", selectedRange = {0,3}, marked text at the end : "??" then I do: [_textView setMarkedText:@"?" selectedRangeNSMakeRange(0,3)]; Result : text :"AAA", selectedRange: {0,3}, markedText: nil; (the marked text became nil) In both cases is like setMarkedText:selectedRange: would be setting the current marked text (if some) to nil. Any help would be highly appreciated :)

• iPad popover - resignFirstResponder issue

  - by mosdev

  I have two text fields email and password. The following code works fine when the fields are presented on a regular view but when they are on a popover, the resignFirstResponder does not work (becomeFirstResponder works). textFieldsShouldReturn was called for both fields. Any idea if I am missing something? Thanks! - (BOOL)textFieldShouldReturn:(UITextField *)theTextField { if (theTextField == email) { [password becomeFirstResponder]; return NO; } [theTextField resignFirstResponder]; return NO; }

• NSNumberFormatter weirdness with NSNumberFormatterPercentStyle

  - by rein

  Hi, I need to parse some text in a UITextField and turn it into a percentage. Ideally, I'd like the user to either type something like 12 or 12% into the text field and have that be parsed into a number as a percentage. Here's what's weird. The number formatter seems to not like 12 and seems to divide 12% by 10000 instead of 100: NSNumberFormatter *formatter = [[[NSNumberFormatter alloc] init] autorelease]; [formatter setNumberStyle:NSNumberFormatterPercentStyle]; NSNumber *n1 = [formatter numberFromString:@"12"]; NSNumber *n2 = [formatter numberFromString:@"12%"]; NSLog(@"n1 = %@", n1); // n1 = (null) NSLog(@"n2 = %@", n2); // n2 = 0.0012 How do I get the formatter to return 0.12 as expected? EDIT: it seems to only happen if the formatter fails first. If the formatter does not fail it returns 0.12 as expected. Strange.

• iphone - UIViewController header view errors

  - by Fiona

  Hi there, So to give a little background: I've an app that has a UITableViewController- (ContactDetailViewController) In this view at the top, I require a few labels and buttons, followed by a group style tableview. So I've created a nib file containing these elements. (ContactHeaderView.xib) Then in the viewDidLoad of ContactDetailViewController I've loaded this nib as the headerView.

In IB I've hooked up the labels/buttons/textbox to the File's Owner (set the File's Owner Class to: ContactDetailViewController) Anyone any idea what I'm doing wrong? Regards, Fiona

• URL Encoding of Characters in a password field

  - by Alavoil

  I am trying to pass login credentials to a PHP script that I have in my iPhone app. When I pull a password with special characters the password is missing certain characters especially the percent sign. I am trying to encode the text but even before I send it, the percent sign is missing. //password_field is a UITextField holding the password: !@#$%^&*() NSString *tmpPass = [password_field.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(p_field.text); NSLog(tmpPass); This is what appears in the console: !@#$^&*() [email protected]&*() Is there any reason why it would be dropping the percent sign?

• UITableView with Core Data and fetchedResultsController - don't want to call it at start up

  - by zebulon

  Hi all, I started with the Navigation-based application. I have a UITableView that shows the content fetched from CoreData - using the - (NSFetchedResultsController *)fetchedResultsController from the template. The thing is that I don't want to fill the TableView with the results at the start-up, instead I want to fill the TableView with the results from a search. In my app I have an UITextField, where the user can type a string. And from that string, using predicate, I want to fill the UITableView with the results. In other words, at start-up, the UITableView should be empty and later filled with the search-results. Does anyone have an idea on how to accomplish this? Thanks in advance! EDIT: Solved it by moving out if (![fetchedResultsController_ performFetch:&error]) { and calling it later. I feel a bit stupid ;)

• Why can't I save changes to application settings with NSUserDefaults?

  I am using the following code to save values from a settings view that takes values from a UITextField and stores them with NSUserDefaults. The code below even calls synchronize yet it is not saving the changes. What am I doing wrong here? - (IBAction)save { NSLog(@"save"); NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; if (self.usernameTextField.text != nil) { NSLog(@"username: %@", self.usernameTextField.text); [defaults setObject:kTwitterUsernameKey forKey:self.usernameTextField.text]; } if (self.passwordTextField.text != nil) { NSLog(@"password: %@", self.passwordTextField.text); [defaults setObject:kTwitterPasswordKey forKey:self.passwordTextField.text]; } [defaults synchronize]; [self dismissModalViewControllerAnimated:TRUE]; }

• iPhone/ObjC - How to create a custom keyboard

  - by HM1

  Hi, iPhone/objC question: How do I go about creating a custom keyboard/keypad that will show up when some one taps on a UITextField? I would like to display a keypad with a, b, c, 1, 2, 3 and an enter button, nothing else. The keypad should work and behave like the standard keyboard does (in behavior) but it will definitely look different. I can't find any example and the best I've found is to filter characters with existing keyboard which is an unacceptable solution. Thanks in advance, Hiren.

• Where I should call [object release] ?

  - by mongeta

  Hello, I've subclassed some UITextField and added some custom properties. In a UITableViewController, in the ViewDiDLoad I init them, and in the cellForRowAtIndexPath I add them to the cell with [cell.contentView addSubview:customTextField]; Each cell has a different customTextField as all of them are very different. Where I should call the [customTextField release] ? After I add them to the cell view ? If for example I call [self.tableView reloadData] my customTextField are going to be added again to the cell, so maybe I should change my approach in doing this ? thanks for the orientation ... regards, r.

• Ensure User has entered string in correct format?

  - by Daniel Granger

  Hi, Whats the best way to ensure the user has entered a valid time string such as: 5:24 5.4 102:30 102.5 It will be entered into a UITextField therefore will be in a NSString. I want to allow the user to enter the time in either hours and minutes (hh:mm) or hours and decimal minutes (hh.m). In the hours minutes example they should be able to enter as many hours as the like but only between 0 - 59 minutes. With the hours decimal minutes I want them to only be able to enter again as many hours as the like but decimal minutes can only be 0 - 9. Many Thanks

• In-App review feature in iPhone App

  - by boreas

  I have recently seen in some Apps that review and rating (with 5 stars) can be integrated into the app. Does anyone have an idea how this is done? e.g. with a http request? More specific: Can I create a view in my App with a UITextField and a Button, so that when the user writes his review in the textfield and click send, the review should be posted to the "Customer Reviews" in the App Store? and the rating should also be done inside the App similarly.

• Check if NSString "000001XX"is a number with intValue

  - by Kenny

  Now I am trying to add a front end check on my app to detect if user input only number in the textfield. I use: - (IBAction)checkID:(UITextField *)sender { if ([sender.text isEqualToString:@""]) { sender.text = @"This information is required"; sender.backgroundColor =[UIColor redColor]; }else if (![sender.text intValue]) { sender.text = [sender.text stringByAppendingString:@" is not valid number"]; sender.backgroundColor =[UIColor redColor]; } NSLog(@"send.text is %@, intValue is %d",sender.text,[sender.text intValue]); } But I found it text begins with number and ends with string, its intValue is still the number. In my text, text is "00001aa", but the intValue is 1. Is there any other way to filter out this "00001aa" text? Thanks in advance.

• How should I set up UITableViewCell subclasses with UIControls in them?

  - by GeneralMike

  I have a dynamically generated UITableView (so I have to use prototype cells, not static cells) with many cells on it. Each cell will have a UILabel on it. Additionally, each cell will also have at least one UIControl (as of right now, it could be a UITextfield or a UISegmentedControl, but I want to keep it flexible in case I add something else in the future). I'm going to need to be able to send the text in that label, and get either the text in the textfield, or the title of the selected segment index, etc. For the cells with multiple controls, I'm going to have to also let it know what control I'm interested in for that call. What would be the best way to set this up?

• iPhone nextResponder switching keyboards

  - by Steve

  iPhone SDK 3.2 Beta 4 (I am downloading B5 to see if this clears this up) To me this seems like a bug, but maybe I am missing something. The linked test program illustrates this problem. I have several UITextFields that I am linking together using the Tag property. In textFieldShouldReturn I get the next UITextField and set it as the active responder. The problem arises with the IB settings for the keyboard type. In the test program I have the first two text fields set to default. The next three text fields are set to numeric and symbols. As you move into the set (bottom three) that use the numeric/symbol keyboard the keyboard will toggle between numeric/symbol and the default. What I mean is the third field will display the numeric/symbol. The second Default. The third numeric/symbol. If you add more text fields setup as numeric/symbol this will continue on. Now if you tab into the forth field (it should bring up the default) and then manually select the numeric/symbol. The problem will disappear. I have tried various things to track down why the problem disappears. No luck so far. Sample Project

• How do I locate the CGRect for a substring of text in a UILabel?

  - by bryanjclark

  For a given NSRange, I'd like to find a CGRect in a UILabel that corresponds to the glyphs of that NSRange. For example, I'd like to find the CGRect that contains the word "dog" in the sentence "The quick brown fox jumps over the lazy dog." The trick is, the UILabel has multiple lines, and the text is really attributedText, so it's a bit tough to find the exact position of the string. The method that I'd like to write on my UILabel subclass would look something like this: - (CGRect)rectForSubstringWithRange:(NSRange)range; Details, for those who are interested: My goal with this is to be able to create a new UILabel with the exact appearance and position of the UILabel, that I can then animate. I've got the rest figured out, but it's this step in particular that's holding me back at the moment. What I've done to try and solve the issue so far: I'd hoped that with iOS 7, there'd be a bit of Text Kit that would solve this problem, but most every example I've seen with Text Kit focuses on UITextView and UITextField, rather than UILabel. I've seen another question on Stack Overflow here that promises to solve the problem, but the accepted answer is over two years old, and the code doesn't perform well with attributed text. I'd bet that the right answer to this involves one of the following: Using a standard Text Kit method to solve this problem in a single line of code. I'd bet it would involve NSLayoutManager and textContainerForGlyphAtIndex:effectiveRange Writing a complex method that breaks the UILabel into lines, and finds the rect of a glyph within a line, likely using Core Text methods. My current best bet is to take apart @mattt's excellent TTTAttributedLabel, which has a method that finds a glyph at a point - if I invert that, and find the point for a glyph, that might work. Update: Here's a github gist with the three things I've tried so far to solve this issue: https://gist.github.com/bryanjclark/7036101

• Only last row in method execute (Objective-C)

  - by Emil

  First I want to apologize for my lack of knowledge in programming in general. I am in the way of learning and have discovered that this site is a huge compliment for me of doing so. I have created a program with three UITextField(thePlace,theVerb,theOutput) and two UITextView where one of the textviews(theOutput) take the text from the other textview(theTemplate) and replaces some strings with the text entered in the textfields. When I click a button it triggers the method createStory that is listed below. This works fine with one exception. The text in the output only changes the string 'number' to the text in the textfield. However if I change the order in the method to replace 'place','number','verb' only the verb is changed, not the number. Im sure this is some sort of easy fix but I can't find it. Can some of you help me with my troubleshooting? - (IBAction)createStory:(id)sender { theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<place>" withString:thePlace.text]; theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<verb>" withString:theVerb.text]; theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<number>" withString:theNumber.text]; } Many thanks // Emil

• UIPickerView crashing when switching segemented control

  - by Mattog1456

  Hello, I have four NSDictionaries that I would like to use to populate a pickerview depending on a segemented control. With the code I have, the first segmented control/pickerview works fine but when I switch to the second segment the picker view only loads part of the second dictionary, that is it loads the same number of rows as it counted in the first dictionary. When I change the segmented control to the third or fourth segment it simply crashes with a sigabrt error indicating that it cannot index item43 when only 27 exist. This I suspect stems from a UItextfield population based on the upickerview row and object. I think the problem is with the way I have the data source and delegate set up. #pragma mark - #pragma mark UIPickerViewDelegate - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { if ([wine selectedSegmentIndex] == 0) { return [robskeys objectAtIndex:row]; } if ([wine selectedSegmentIndex] == 1) { return [esabskeys objectAtIndex:row]; } if ([wine selectedSegmentIndex] == 2) { return [lebskeys objectAtIndex:row]; } else if ([wine selectedSegmentIndex] == 3) { return [sbskeys objectAtIndex:row]; } return @"Unknown title"; } #pragma mark - #pragma mark UIPickerViewDataSource - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; } - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { if ([wine selectedSegmentIndex] == 0) { return robskeys.count; } if ([wine selectedSegmentIndex] == 1) { return esabskeys.count; } if ([wine selectedSegmentIndex] == 2) { return lebskeys.count; } else if ([wine selectedSegmentIndex] == 3) { return sbskeys.count; } return 1; } #pragma mark - Any help would be much appreciated Thank you
