C validating text box of christian dating sites
To overcome this problem I have created an inherited class of “UIText Field” called “Text Field Validator” in which you just need to give them all the regex string that you want to validate in a particular textfield, no matter how many types of validation you want to perform you just need to give them in sequence.
I’m sure this will save your lot of time in development and good news is that you can easily integrate “Text Field Validator” into your previous application without putting much effort. Either you can drag UIText Field in the view, change their class name to “Text Field Validator” and create outlet or create instance programmatically. You need to assign a view to “present In View” data member of “Text Field Validator” class on which you want to show error popup.
If you are managing text field from storyboard/xib then you can directly assign outlet of “present In View” to any view. You can assign delegate in the similar way as you do for UIText Field. Now you need to assign all your validation regex in sequence as per below code 5.
Now on form submission event you need to check whether all textfields validations get successfully executed or not, for this you just need to call “validate” method and this method will return YES if all the validations you provided is successfully executed and if they return NO then textfield will automatically show error icon at the right side of textfield and when user will tap on that icon a popup will show with message corresponding to the validation that get failed.
This is very important, since this code WILL be reached if the clientside validation is not used, for some reason.
In the app I am working with I do have a pop-up window that shows a html version of all the errors in the input (not only textboxes and intboxes but also in listboxes, radiogroups and so on), but it would also be nice to get the error message to show up on the respective component, at least for text- and intboxes. @Rico You can try to give the component a constraint, just like checkbox Constraint(No Empty Constraint), and customize the constraint by your own.
I'm sure that all the attributes of the controls makes sense by now, so I won't go into details about them. You should see something like this: If your browser supports Java Script, which most modern browers do, then you will notice that the page is not being posted back to the server - the validation is performed clientside! To see how it feels, you can add enableclientscript="false" to the Required Field Validator and try again.
Now you will see the browser posting back to the server, but the result will be the same - the validator still works!
As you see, it's very simple - just check the Page. Try to run the website again, and notice how the text of the button is changed if you submit a valid form.
I'm just trying to solve this little problem for hours now and I don't get the solution, so perhaps someone can help?
