uitextfield

I have a UITextField on my aplication that receives only numeric input from the user. This numeric input represents currency and have the default value of 0.00. I would like to create something like a mask to format the UITextField as the user enter the numbers. For example: 9 becomes $0,09 99 becomes $0,99 999 becomes $999,99 The code below works great, but as I'm using integer and float values the app will eventually display wrong values afeter a certain point. For example: 999999999 becomes 100000000 That happens because flot and integer aren't precise enough and NSDEcimalNumber should be

I found an annoying problem. I have a textfield with the numeric decimal keyboard, but the simulator has the point, the device has the comma (both 6.1). How can I do, if you insert a comma, this is replaced by a point? Thanks EDIT: this process, must take place in this method, in real time - (BOOL) textField: (UITextField *) theTextField shouldChangeCharactersInRange: (NSRange) range ReplacementString: (NSString *) string otherwise the comma is written, and at the next character, it is replaced HDdeveloper You can use - (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target

I know that there is a lot of info on the Internet about that question but I am stuck. I have app in which I need to customise my UITextFields . For example I need change border colour when edit starts or I need limitation of how many characters I can set in different text fields. I also need an image in several text fields which has to be indented on the left. To do all this I decided to make custom UITextField class (to subclass UITextField). I created new class from UITextField (which implements <UITextFieldDelegate> ). In that class I use self.delegate = self (this is widely used on the

I am making this kind of password to skip levels in a game. But I dont know what code I need to make a button change View Controller... - (IBAction)button:(id)sender { if ([txt.text isEqualToString:@"passwordToSkipLevel1"]) { // Code to change View Controller??? } } I am not sure if I have done it correct to far, and I am not sure how I can make it change View Controller either... Any ideas? Extra: Is there any method to make the password not case sensetive? What you have seems fine as far as it goes. To make the comparison case-insensitive, you can use if ([txt.txt

I have a tableView with custom cells. One of the objects in the cell is a textField. The tableViewController is the textFieldDelegate. The datasource for the table is an array of objects. When the user tap on the textField, the tableViewController implements textField delegates methods controlling this way the data entry. To use the data entered by user, the tableViewController implements the following: - (BOOL)textFieldShouldEndEditing:(UITextField *)textField { CGPoint point = [textField center]; point = [self.tableView convertPoint:point fromView:textField]; NSIndexPath *indexPath = [self
