every one i create custom keyboard and i have problem
iam using my keyboard as textview.inputView = myKeyboardView;
my keyboard buttons have this code :
NSMutableString *text = [textPad.text mutableCopy];
NSRange selectedRange = textPad.selectedRange;
[text replaceCharactersInRange:selectedRange withString:#"A"];
textPad.text = text;
[text release];
so the problem is when i want edit a word from middle of my sentence if i select a word and add some letters to that my button write only ONE Character and if i write some other letters that begin end of sentence ! what can i do to solve this problem ?

PROBLEM SOLVED
My first guess is that you need to set selectedRange. Also consider using convenience constructors rather than explicitly creating mutable copies — you only mutate it once so it's not likely to be any more efficient.
NSString *text = textPad.text;
NSRange selectedRange = textPad.selectedRange;
NSString *replacement = #"A";
text = [text stringByReplacingCharactersInRange:selectedRange withString:replacement];
selectedRange = (NSRange){selectedRange.location + replacement.length, 0};
textPad.text = text;
textPad.selectedRange = selectedRange;

I am trying to get the first sentence of a text view. I have the following code but am getting an out of bounds error. Thank You. Or are there any ways that aren't really complex.
-(IBAction)next:(id)sender
{
NSRange ran = [[tv.text substringFromIndex:lastLocation] rangeOfString:#". "];
if(ran.location != NSNotFound)
{
NSString * getRidOfFirstHalfString = [[tv.text substringFromIndex:lastLocation] substringToIndex:ran.location];
NSLog(#"%#",getRidOfFirstHalfString);
lastLocation+=getRidOfFirstHalfString.length;
}
How about:
NSString *finalString = [[tv.text componentsSeparatedByString:#"."] objectAtIndex:0] // Get the 1st part (left part) of the separated string
Go through the textview's text and divide the text into separate components where you find a period by calling componentsSeperatedByString on tv.text. You want the first sentence, which would be the 0th object in the array.
I know you've already accepted an answer to this question, but you might want to consider using the text view's tokenizer instead of just searching for the string ". " The tokenizer will automatically handle punctuation like !, ?, and closing quotes. You can use it like this:
id<UITextInputTokenizer> tokenizer = textView.tokenizer;
UITextRange *range = [tokenizer rangeEnclosingPosition:textView.beginningOfDocument
withGranularity:UITextGranularitySentence
inDirection:UITextStorageDirectionForward];
NSString *firstSentence = [textView textInRange:range];
If you want to enumerate all of the sentences, you can do it like this:
id<UITextInputTokenizer> tokenizer = textView.tokenizer;
UITextPosition *start = textView.beginningOfDocument;
while (![start isEqual:textView.endOfDocument]) {
UITextPosition *end = [tokenizer positionFromPosition:start toBoundary:UITextGranularitySentence inDirection:UITextStorageDirectionForward];
NSString *sentence = [textView textInRange:[textView textRangeFromPosition:start toPosition:end]];
NSLog(#"sentence=%#", sentence);
start = end;
}
Try checking that the substring was actually found.
NSRange ran = [tv.text rangeOfString:#". "];
if(ran.location != NSNotFound)
{
NSString * selectedString = [tv.text substringToIndex:ran.location];
NSLog(#"%#",selectedString);
}
You could alternatively try using NSScanner like this:
NSString *firstSentence = [[NSString alloc] init];
NSScanner *scanner = [NSScanner scannerWithString:tv.text];
NSCharacterSet *set = [NSCharacterSet characterSetWithCharactersInString:#"."];
[scanner scanUpToCharactersFromSet:set intoString:&firstSentence];
I'm not sure if you want this, but since you want the first sentence, you could append a period (you probably know how to do this, but it doesn't hurt to show it anyway):
firstSentence = [firstSentence stringByAppendingFormat:#"."];
Hope this helps!
PS: If it didn't work for you, maybe the text view doesn't actually contain any text.
i have this code to show some texts in a UITextview..i just want to add a UILabel between these strings.i am getting text in this formate, 1 this is first text 2 this is second text 3 this is third text,,i want to add or append UILabel between numeric character and text.my code for showing text is
NSMutableString *combined = [NSMutableString string];
for(NSUInteger idx = 0; idx < [delegatee.allSelectedVerseEnglish count]; idx++) {
[combined appendFormat:#" %d %#",
idx + 1,
[delegatee.allSelectedVerseEnglish objectAtIndex:idx]];
}
NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
NSNumber * n = [f numberFromString:combined];
NSLog(#"N: %#", n);
maintextview.text =combined;
combined is the text in the above formate ,and maintextview is the UITextview.
am also getting the string range between two sentence
- (void)textViewDidEndEditing:(UITextView *)textView
{
if (textView == maintextview) {
mainpopupview.frame =CGRectMake(0, 0, 768, 1004) ;
[self.view addSubview:mainpopupview];
NSRange selectedRange = [textView selectedRange];
NSString *backString = [maintextview.text substringToIndex:selectedRange.location];
NSRange backRange = [backString rangeOfString:#" " options:NSBackwardsSearch];
NSRange backRangee = [backString rangeOfString:#" " options:NSBackwardsSearch];
int myRangeLenght = backRangee.location - backRange.location;
NSRange myStringRange = NSMakeRange (backRange.location, myRangeLenght);
NSString *forwardString = [maintextview.text substringFromIndex:backRange.location];
NSLog(#"%#",[[forwardString componentsSeparatedByString:#" "] objectAtIndex:1]);
NSLog (#"%#", [maintextview.text substringWithRange:myStringRange]);
NSString * myStringTxt = [[forwardString componentsSeparatedByString:#" "] objectAtIndex:1];
NSLog(#"1 %#", myStringTxt);
// maintextview.textColor = [UIColor yellowColor];
NSRange myStringRangee = [maintextview.text rangeOfString:myStringTxt];
[maintextview select:self];
maintextview.selectedRange = myStringRangee;
is there any way to do this.
Thanks in advance.
I don't know what user interaction you need here, but if you're just displaying the text for the user, but could you replace your UITextView with a UIWebView (loading static text via loadHTMLString:baseURL:, using html markup to set the color of the text)? I refer to the UITextView documentation:
This class does not support multiple styles for text. The font, color,
and text alignment attributes you specify always apply to the entire
contents of the text view. To display more complex styling in your
application, you need to use a UIWebView object and render your
content using HTML.
If you really need to do this with separate UI controls (much more complicated than just using a UIWebView) you don't "insert" the UILabel in the text, but rather you'd probably have one control for the text up to the point of the color change, another control for the text of a different color or what have you, another control for the rest of the text. It would get hairly pretty quickly (unless it was laid out like a grid, and even then it's a hassle compared to a UIWebView).
I have a paragraph (4 sentences) of text in an .plist array that loads into a UITextView.
By default, it presents the text how it is, as one big lump of text in a paragraph. I want to know if it is possible to split this up?
Such as Line 1: sdfafasfsafsa, then line 2: asfdsafs, line 3: adfsfsdfsdfa, etc.
Is there a way I can search for a . and then separate the lines accordingly? I would just edit the plist manually but there are hundreds of entries so it isn't easy to do.
NSString* tidiedString = [sourceString stringByReplacingOccurrencesOfString:#"." withString:#"\n"];
Update: OK, so more detail is coming through. You could use a regular expression - but if you're not familiar, the learning curve is a bit steep. Otherwise, as with other answers, crank through the list. You need to take care of whitespaces, empty lines etc. The following snippet isn't pretty, but will do the job.
NSString* sourceString = #"Hyperlinks can be great. They can also dilute your focus and tempt you into putting off what you most want to do. Here I chose to place links at the foot of the page to help you to make an active choice as to whether to surf or refocus your attention elsewhere.";
NSArray* arrayOfStrings = [sourceString componentsSeparatedByString:#"."];
NSMutableString* superString = [NSMutableString stringWithString:#""];
int lineCount = 1;
for (NSString* string in arrayOfStrings)
{
if ([string length] < 1) continue;
[superString appendFormat:#"Line %d: %#.\n", lineCount++, [string stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]]];
}
[superString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
[[self userEntry] setText:superString];
NSArray *array = [sourceString componentsSeparatedByString:#"."];
NSMutableString *resultString= [[NSMutableString alloc] init];
int linecount=1;
for(NSString *lines in array)
{
[resultString appendString:[NSString stringWithFormat:#"Line%i:%#\n",linecount++,lines]];
}
NSLog(#"resultString:%#",resultString);
this may help..!!
Try making a loop that runs through the array and that adds every line to the UITextView plus #"\n".
So something like...:
NSString *curText = txtView.text;
NSString *lineBreak = #"\n";
txtView.text=[NSString stringWithFormat:#"%# + %#", curText, lineBreak];
Or just replace the dots by #"\n".
i have problem with the custom backspace and enter buttons on custom iPhone keyboard ,
The Backspace : my codes just remove characters at the end of the line not from the cursor location .
if ([textView.text length]>0) textView.text = [textView.text substringToIndex:([textView.text length]-1)];
and read this question Custom keyboard iphone , having problem with backspace button in UITextView but didn't solve my problem .
The Enter : i have same problem like backspace the enter button just the inserts new line at the end of sentence not not from the cursor location .
textView.text = [NSString stringWithFormat:#"%#\n", textView.text];
how should i change my codes to work fine ? thank you
EDIT :
//BACKSPACE BUTTON CODE :
NSRange deleteRange = textPad.selectedRange;
deleteRange.length -= 1;
if ([textPad.text length]>0) textPad.text = [textPad.text stringByReplacingCharactersInRange:deleteRange withString:#""];
here is the best iphone custom backspace code :D :
NSRange deleteRange = textPad.selectedRange;
if (deleteRange.length >0)
textPad.text = [textPad.text stringByReplacingCharactersInRange:deleteRange withString:#""];
else
if (deleteRange.location > 0)
textPad.text = [textPad.text stringByReplacingCharactersInRange:NSMakeRange(deleteRange.location-1,1)
withString:#""];
deleteRange.location--;
deleteRange.length = 0;
textPad.selectedRange = deleteRange;
textView.text = [textView.text stringByReplacingCharactersInRange:textview.selectedRange withString:#"\n"]; // Replace the selected characters with a new line
or
textView.text = [textView.text stringByReplacingCharactersInRange:textview.selectedRange withString:#""]; // Delete the selected character
You can use the UITextView selectedRange method to determine the beginning and end of the selected text, and delete from that range instead of from the end of the string.
Is there a way to accomplish something like the html Marquee effect for a uitableviewcells textlabel.text?
You'll have to implement it yourself using a NSTimer. You would cycle trough the characters of your textLabel.text by taking one from the front and appending it to the back. In order to do this easily you could use a NSMutableString that you would manipulate using substringWithRange: deleteCharactersInRange: and appendString, and then set as textLabel.text after each character manipulation:
- (void)fireTimer
{
NSMutableString *mutableText = [NSMutableString stringWithString: textLabel.text];
//Takes the first character and saves it into a string
NSString *firstCharText = [mutableText substringWithRange: NSMakeRange(0, 1)];
//Removes the first character
[mutableText deleteCharactersInRange: NSMakeRange(0, 1)];
//Adds the first character string to the initial string
[mutableText appendString: firstCharText];
textLabel.text = mutableText;
}
