I have two UITextFields in my storyboard that are meant to take in a number that the user inputs, a minPrice and maxPrice. When I click submit in the simulator, the app crashes and I receive the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[3]'

Cloud Code:
Parse.Cloud.define("userCategorySave", function(request, response) {
var userCategory = Parse.Object.extend("userCategory");
var newUserCategory = new userCategory();
newUserCategory.set("categoryId", request.params.categoryId);
newUserCategory.set("minPrice", request.params.minPrice);
newUserCategory.set("maxPrice", request.params.maxPrice);
newUserCategory.set("itemCondition", request.params.itemCondition);
newUserCategory.set("itemLocation", request.params.itemLocation);
newUserCategory.set("parent", Parse.User.current());
newUserCategory.save({
success: function (){
console.log ('userCategory successfully created!');
response.success('userCategory successfully created!');
},
error: function (){
console.log('error!!!');
response.error('Request failed');
}
});
});
I assume the issue is that the UITextFields are sending the numbers in a format my cloud code doesn't like. In addition to this error, I would like to set it so that only numbers are allowed when inputting a value in this field.
How can I programmatically create these two fields in a way that will send the data in a format thats compatible with the cloud code, and that only allows numbers?
