I am using UILexicon for the suggestions in custom keyboard. Following is code:
-(void) keyTapped:(UIButton*)button {
[self requestSupplementaryLexiconWithCompletion:^(UILexicon *lexicon){
// self.lexicon = lexicon;
NSLog(#"%#",lexicon.entries);
for (UILexiconEntry* entry in lexicon.entries) {
NSLog(#"%#=%#",entry.userInput,entry.documentText);
}
int i=0;
}];
}
But it is returning always same array of entries. Can anyone suggest me how to use it. I will mark correct your answer if it works. Thanks.
It's working but you should implement your own function to compare the UILexiconEntry list with the entered string as stated by apple :
UILexiconEntry
A lexicon entry specifies a read-only term pair, available within a UILexicon object, for use by a custom keyboard.
You can employ a lexicon entry by matching user input against the entry’s userInput value, and then inserting into the current text input object the corresponding documentText value. For example, if the user typed the string “iphone”, the lexicon entry with that exact, case-sensitive string in the userInput property has the string “iPhone” in the corresponding documentText property.
In some cases, the documentText string is in a different text script than the userInput string.

I want create an iOS app for my school.
This App will show Week schledule and when I tap on Cell with Subject, it will show me detail info about subject...
My problem:
Our teachers use shotcuts for their names, but I want show their full name... I created the file "ucitele.h" with definitions of their names, but I don't know, how to use it 😕.
This is how that file looks:
//
// ucitele.h
//
#define Li #"RNDr. Dan---vá"
#define He #"Mgr. Ja---hl"
#define Sm #"Ing. Mich---rek"
#define Ks #"Mgr. Svat---á"
I get the shortcut of Teacher from previous view from "self.ucitel" and I maybe want compare the contents of the "self.ucitel" with definitions and set the "ucitelFull" string from the definitions? I don't know how to say it 😕.
when the content of the self.ucitel will be #"Sm", than I want parse "ucitelFull" as #"Ing. Mich---rek"
Answers in Objective-C only please
Okay, sounds like your trying to map a short identifier to a full name:
-(NSString*)fullNameFromShortName:(NSString*)short {
NSDictionary * names = #{#"Li" : #"RNDr. Dan---vá",
#"He" : #"Mgr. Ja---hl", ... };
return [names objectForKey:short];
}
Use like:
self.ucitelFull = [self fullNameFromShortName:self.ucitel];
This is a dictionary that has the short name as a key and the full name as the value.
Some further suggestions:
try using lowercase keys and comparing lowercaseString's, incase the user doesn't enter the value with the correct case.
You can move the dictionary definition into a json file and read it from your bundle, to eliminate the hardcoding
lets say we have some grammar like this.
Model:
greeting+=Greeting*;
Greeting:
'Hello' name=ID '!';
I would like to check whether the text written text in name is a valid text.
All the valid words are saved in an array.
Also the array should be filled with words from a given file.
So is it possible to check this at runtime and maybe also use this words as suggestions.
Thanks
For this purpose you can use a validator.
A simple video tutorial about it can be found here
In your case the function in the validator could look like this:
public static val INVALID_NAME = "greeting_InvalidName"
#Check
def nameIsValid(Greeting grt) {
val name = grt.getName() //or just grt.Name
val validNames = NewArrayList
//add all valid names to this list
if (!validNames.contains(name)) {
val errorMsg = "Name is not valid"
error(errorMsg, GreetingsPackage.eINSTANCE.Greeting_name, INVALID_NAME)
}
}
You might have to replace the "GreetingsPackage" if your DSL isn't named Greetings.
The static String passed to the error-method serves for identification of the error. This gets important when you want to implement Quickfixes which is the second thing you have asked for as they provide the possibility to give the programmer a few ideas how to actually fix this particular problem.
Because I don't have any experience with implementing quickfixes myself I can just give you this as a reference.
In my Grails project I have a Domain Class with a double field as follows:
double totalAmount;
the value of this field are calculated by a sum done after selecting values in a multiple select. the function for sum values is in the controller, as follows:
def sumReceiptItems(){
params.list("receiptItemsSelected").each {i-> println("element "+i)}
def appList = params.list("receiptItemsSelected")
List<ReceiptItem> allSelectedIds = ReceiptItem.findAllByIdInList(params.receiptItemsSelected.split(',')*.toLong())
def totalAmount = allSelectedIds.amount.sum()
println("totalAmount is = "+totalAmount)
render totalAmount as Double
}
the function works well. After function calling, to update the field in GSP page, I use a javascript method as follows:
function updateTotalAmount(name, data, presentNullAsThis){
if(data !=null)
document.getElementById(name).value= data;
else
document.getElementById(name).value=presentNullAsThis;
}
The javascript works and I see the updating of the field at runtime, but the double value is shown with a dot, and not with comma to separate decimal values. Infact, after clicking by save button to save the instance of the domain class, the value is saved without separating decimals, for example:
if the value into the fiels is 10.50 it is stored as 1050
In this discussion how can save a double type correctly in grails? I've read a similar problem, but solution is not good for my issue.
Anybody can help me?
Values with decimal separator depends on the current Locale of the user. Normally you use g.formatNumber in the view to display correctly the value.
You can check this topic on how to discover the decimal separator for a Locale.
To get the user's Locale use:
Locale locale = RequestContextUtils.getLocale(request)
I have solved the problem in this way:
I've updated my Javascript as follows:
function updateTotalAmount(name, data, presentNullAsThis)
{
var data2 = data.toString().replace(/\./g, ',');
if(data2 != null) document.getElementById(name).value= data2;
else document.getElementById(name).value= presentNullAsThis;
}
I've removed "type="number"" in the gsp related field
I'm currently teaching myself the Dart language, and my first app doesn't seem to be working right. Here's the code that's causing trouble:
usrLoc = int.parse(query("#txtLoc").text);
When I try to run the app, it opens fine, but when I click the button that triggers this (and three other similar parses), the debugger stops and tells me "Source not found" for int._native_parse(), int._parse(), and int.parse().
Any help would be greatly appreciated.
The text property for the specified element #txtLoc returns an empty string.
The parse method requires that:
The source must be a non-empty sequence of base- radix digits, optionally prefixed with a minus or plus sign ('-' or '+').
You can specify an onError named argument in your call to parse, which takes a callback that handles the invalid input. E.g., if you want the parse call to return the value 42 for all invalid input, you can do this:
usrLoc = int.parse(query("#txtLoc").text, onError: (val) => 42);
If you really expect the element to have some text, you can store the result of query("#txtLoc").text into a separate variable and verify the value. It would also be interesting to check what the real element type is or which tag is marked with id #txtLoc.
If you want to get the content of an input element, you should use the value property instead of text:
query("#txtLoc").value
I have created a domain with a Double field. When the validation occurs it throws the error message with size value showing the number with commas. Following are the detials
Groovy Class
class Quote {
String content;
Double size;
static constraints = {
content(maxSize:1000, blank:false)
size(min: 0.00D, max:999.99D)
}
}
Value entered "11111", error obtained "Size 11,111 is exceeded the limit". I have added the property key/value pair in messages.properties.
Here, I would like to get the message back without the commas. My main aim is to take the key and format the message returned based on my requirements. I require this as I have other fields that need conversion. For example, a date is validated but when showing the error the Gregorian date needs to be converted to an Islamic date and shown to user.
Does anyone know if I can do something to make this work.
I have tried the solution provided in http://ishanf.tumblr.com/post/434379583/custom-property-editor-for-grails but this did not work.
I have also tried modifying the messages values, but this is not flexible in case of my date issue. Example, for a key value pair, instead of using {2} as a place holder I could use {2, date, mm/dd/yyyy}, but for Islamic dates I want to format and show things differently.
Also, please note I have created a separate key for default date formatting for my application.
Would appreciate the help.
In grails, the return of a constrain is an already translated string.
You can create a taglib to format that, or enhance the
Another option would be custom validators. A custom validator can return false or a key when failing.
For example in your domain class, to vaildate a field:
myDateField validator: {val, obj -> obj.myShinyDateValidatorMethod(val) }
private myShinyDateValidatorMethod() {
if (isNotValidDate(val) {
return [the_message_key, val.formatedAsYouWand]
}
}
and, in your properties file you have to have defined the key:
the_message_key=This date: {3} is not valid
The trick here is that in the return from the validator, first string is the key and the rest are parameters for that key, but grails already uses {0}, {1}, {2} placeholders for className, fieldName and value, and the first parameter that you pass will be used as {3} placeholder.
Hope this helps
