Is it possible to add all the lines of an address to a text view, so far I can only get the last line to show up in the view adresslines.
self.adresslines.text = (NSString *)(CFDictionaryGetValue(dictionary, kABPersonAddressCityKey));
self.adresslines.text = (NSString *)(CFDictionaryGetValue(dictionary, kABPersonAddressStreetKey));
self.adresslines.text = (NSString *) (CFDictionaryGetValue(dictionary, kABPersonAddressZIPKey));
As you have it now you are setting the text view's text with each line of the address. You want to append, not replace. Something like this will work:
NSMutableString *text = [NSMutableString string];
[text appendString:(NSString *)(CFDictionaryGetValue(dictionary, kABPersonAddressCityKey))];
[text appendString:#"\n"];
[text appendString:(NSString *)(CFDictionaryGetValue(dictionary, kABPersonAddressStreetKey))];
[text appendString:#"\n"];
[text appendString:(NSString *) (CFDictionaryGetValue(dictionary, kABPersonAddressZIPKey))];
self.addresslines.text = text;
Of course you can add checks in here to avoid blank lines or add other formatting as desired.

In an NSTextStorage I insert time strings at the current pointer location like this :
NSMutableAttributedString* attrString = [[NSMutableAttributedString alloc] initWithString: #"00:00:00"];
[attrString autorelease];
int pos = [self selectedRange].location;
[[self textStorage] insertAttributedString: attrString atIndex:pos];
So far so good, it works perfect. But now I want to position the pointer at the beginning of the next line. Obviously this is right after the next return char.
Now how to find the next return char in textStorage and position the pointer there ?
I have not found any hint in the web for this task. Please help ...
You won't find a method to set the cursor (more precise: selection with zero length) in NSTextStorage's API, because it is a storage, having no selection. The selection is a property of the text view. This is the result of MVC. Simply do a check: You can have many text views displaying the same text. Obviously each one needs its own selection.
What you have to do is to get the position of the next paragraph (this is better than searching for \n) and set this as a selection for the text view.
NSMutableAttributedString* attrString = [[NSMutableAttributedString alloc] initWithString: #"00:00:00"];
[attrString autorelease]; // You should *really* use ARC
int pos = [self selectedRange].location;
[[self textStorage] insertAttributedString: attrString atIndex:pos];
// Get the next paragraph
NSString *text = self.textStorage.string;
NSRange restOfStringRange = NSMakeRange( pos, [text length]-pos );
NSUInteger nextParagraphIndex;
// You have to look to the start of the next paragraph
[text getParagraphStart:&nextParagraphIndex end:NULL contentsEnd:NULL forRange:restOfStringRange];
NSTextView *view = self.textView; // Or where ever you get it from
view.selectedRange = NSMakeRange(nextParagraphIndex, 0);
Typed in Safari, not tested, just to show the basic approach.
I have a UILable which displays text as I press buttons. The text is from an attributed string. One of the buttons calls for a superscript attribute:
string = [[NSMutableAttributedString alloc]initWithString:#"A"];
[string addAttribute:NSFontAttributeName value:(font) range:NSMakeRange(string.length-1, 1)];
[string addAttribute:(NSString*)kCTSuperscriptAttributeName value:#"1" range:NSMakeRange(string.length-1, 1)];
[string2 appendSttributedString: string];
label.attributedText = string2;
This code works as long as string2 fits onto one line in the UILable. When the text begins to span two lines at first it appears as it should. However when the kCTSuperscriptAttributeName superscript attribute is added the second line of the label disappears and gets truncated. Im not sure whats going on. Anyone have an idea?
Make sure that you are setting the numberOfLines property on the UILabel to be 2 or something, so that the label doesn't truncate beyond the first line. Hope this helps!
Did you try 'NSBaselineOffsetAttributeName' for NSAttributedString?
-(void)setText:(id)text withPrefixText:(id)prefixText andSuffixText:(id)suffixText
{
NSString * compondText = [self textByCompoundingText:text withPrefixText:prefixText WithsuffixText:suffixText];
NSMutableAttributedString * attributedCompoundText = [[NSMutableAttributedString alloc] initWithString:compondText];
NSMutableDictionary * prefixTextAttributes = [#{} mutableCopy];
prefixTextAttributes[NSFontAttributeName] = _prefixTextFont? _prefixTextFont:self.font;
prefixTextAttributes[NSForegroundColorAttributeName] = _prefixTextColour? _prefixTextColour:self.textColor;
NSNumber *baselineOffSet =[NSNumber numberWithUnsignedInteger:_prefixTextVerticalPositionning];
prefixTextAttributes[(NSString*)NSBaselineOffsetAttributeName] = baselineOffSet;
NSMutableDictionary * suffixTextAttributes = [#{} mutableCopy];
suffixTextAttributes[NSFontAttributeName] = _suffixTextFont? _suffixTextFont:self.font;
suffixTextAttributes[NSForegroundColorAttributeName] = _suffixTextColour ?_suffixTextColour:self.textColor;
baselineOffSet = [NSNumber numberWithUnsignedInteger:_suffixTextVerticalPostioning];
suffixTextAttributes[(NSString*)NSBaselineOffsetAttributeName] = baselineOffSet;
if(prefixText)
[attributedCompoundText addAttributes:prefixTextAttributes range:[compondText rangeOfString:prefixText]];
if(suffixText)
[attributedCompoundText addAttributes:suffixTextAttributes range:[compondText rangeOfString:suffixText]];
self.attributedText = attributedCompoundText;
}
I want to get the most recent word entered by the user from the UITextView.
The user can enter a word anywhere in the UITextView, in the middle or in the end or in the beginning. I would consider it a word when the user finishes typing it and presses a space and does any corrections using the "Suggestions from the UIMenuController".
Example: User types in "kimd" in the UITextView somewhere in the middle of text, he gets a popup for autocorrection "kind" which he does. After he does that, I want to capture "kind" and use it in my application.
I searched a lot on the internet but found solutions that talk about when the user enters text in the end. I also tried detecting a space and then doing a backward search until another space after some text is found, so that i can qualify it as a word. But I think there may be better ways to do this.
I have read somewhere that iOS caches the recent text that we enter in a text field or text view. If I can pop off the top one , that's all I want. I just need handle to that object.
I would really appreciate the help.
Note: The user can enter text anywhere in UItextview. I need the most recent entered word
Thanks.
//This method looks for the recent string entered by user and then takes appropriate action.
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
//Look for Space or any specific string such as a space
if ([text isEqualToString:#" "]) {
NSMutableCharacterSet *workingSet = [[NSCharacterSet whitespaceAndNewlineCharacterSet] mutableCopy];
NSRange newRange = [self.myTextView.text rangeOfCharacterFromSet:workingSet
options:NSBackwardsSearch
range:NSMakeRange(0, (currentLocation - 1))];
//The below code could be done in a better way...
UITextPosition *beginning = myTextView.beginningOfDocument;
UITextPosition *start = [myTextView positionFromPosition:beginning offset:currentLocation];
UITextPosition *end = [myTextView positionFromPosition:beginning offset:newRangeLocation+1];
UITextRange *textRange = [myTextView textRangeFromPosition:end toPosition:start];
NSString* str = [self.myTextView textInRange:textRange];
}
}
Here is what I would suggest doing, might seem a little hacky but it would work just fine:
First in .h conform to the UITextViewDelegate and set your text view's delegate to self like this:
myTextView.delegate = self;
and use this code:
- (void)textViewDidChange:(UITextView *)textView { // Delegate method called when any text is modified
if ([textView.text substringFromIndex: [textView.text length] - 1]) { // Gets last character of the text view's text
NSArray *allWords = [[textView text] componentsSeparatedByString: #" "]; // Gets the text view's text and fills an array with all strings seperated by a space in text view's text, basically all the words
NSString *mostRecentWord = [allWords lastObject]; // The most recent word!
}
}
I use this code to get the word behind the #-sign:
- (void)textViewDidChange:(UITextView *)textView {
NSRange rangeOfLastInsertedCharacter = textView.selectedRange;
rangeOfLastInsertedCharacter.location = MAX(rangeOfLastInsertedCharacter.location - 1,0);
rangeOfLastInsertedCharacter.length = 1;
NSString *lastInsertedSubstring;
NSString *mentionSubString;
if (![textView.text isEqualToString:#""]) {
lastInsertedSubstring = [textView.text substringWithRange:rangeOfLastInsertedCharacter];
if (self.startOfMention > 0 || self.startOfHashtag > 0) {
if ([lastInsertedSubstring isEqualToString:#" "] || (self.startOfMention > textView.selectedRange.location || self.startOfHashtag > textView.selectedRange.location)) {
self.startOfMention = 0;
self.lenthOfMentionSubstring = 0;
}
}
if (self.startOfMention > 0) {
self.lenthOfMentionSubstring = textView.selectedRange.location - self.startOfMention;
NSRange rangeOfMentionSubstring = {self.startOfMention, textView.selectedRange.location - self.startOfMention};
mentionSubString = [textView.text substringWithRange:rangeOfMentionSubstring];
dhDebug(#"mentionSubString: %#", mentionSubString);
UIAccessibilityPostNotification(UIAccessibilityLayoutChangedNotification, nil);
}
}
}
Simple extension for UITextView:
extension UITextView {
func editedWord() -> String {
let cursorPosition = selectedRange.location
let separationCharacters = NSCharacterSet(charactersInString: " ")
let beginRange = Range(start: text.startIndex.advancedBy(0), end: text.startIndex.advancedBy(cursorPosition))
let endRange = Range(start: text.startIndex.advancedBy(cursorPosition), end: text.startIndex.advancedBy(text.characters.count))
let beginPhrase = text.substringWithRange(beginRange)
let endPhrase = text.substringWithRange(endRange)
let beginWords = beginPhrase.componentsSeparatedByCharactersInSet(separationCharacters)
let endWords = endPhrase.componentsSeparatedByCharactersInSet(separationCharacters)
return beginWords.last! + endWords.first!
}
}
I'm trying to save the content of a UITextView which contains lines of text formatted both RTL and LTR.
The problem is that UITextView checks only the first character to format direction. Let's assume I'm in "edit" mode and write this text (__ means spaces):
text1_______________________________________
____________________________________________אקסא
text2_______________________________________
and after saving we lost RTL for אקסא. Now I'd like to edit this text once again which now looks like:
text1_______________________________________
אקסא
text2_______________________________________
I'm not able to mix \u200F with \u200E directional characters in one UITextView.
How to manage this and save correctly bidirectional text from UITextView?
Here is a quick proof of concept using NSAttributedString :
- Split the text in paragraphs
- For each paragraph, detect the main language
- Create an attributed text with the correct alignmenent for the corresponding range
// In a subclass of `UITextView`
+ (UITextAlignment)alignmentForString:(NSString *)astring {
NSArray *rightToLeftLanguages = #[#"ar",#"fa",#"he",#"ur",#"ps",#"sd",#"arc",#"bcc",#"bqi",#"ckb",#"dv",#"glk",#"ku",#"pnb",#"mzn"];
NSString *lang = CFBridgingRelease(CFStringTokenizerCopyBestStringLanguage((CFStringRef)astring,CFRangeMake(0,[astring length])));
if (astring.length) {
if ([rightToLeftLanguages containsObject:lang]) {
return NSTextAlignmentRight;
}
}
return NSTextAlignmentLeft;
}
- (void)setText:(NSString *)str { // Override
[super setText:str];
// Split in paragraph
NSArray *paragraphs = [self.text componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
// Attributed string for the whole string
NSMutableAttributedString *attribString = [[NSMutableAttributedString alloc]initWithString:self.text];
NSUInteger loc = 0;
for(NSString *paragraph in paragraphs) {
// Find the correct alignment for this paragraph
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init];
[paragraphStyle setAlignment:[WGTextView alignmentForString:paragraph]];
// Find its corresponding range in the string
NSRange range = NSMakeRange(loc, [paragraph length]);
// Add it to the attributed string
[attribString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:range];
loc += [paragraph length];
}
[super setAttributedText:attribString];
}
Also, I recommend reading the Unicode BiDi Algorithm to manage more complex use cases.
Can any body tell me how to add bullet list and numbered list to the selected text in UITextView.
Check this question: iphone bullet point list
You might want to add the unicode char of bulletpoints to your lines (#"\u2022)
NSArray * items = ...;
NSMutableString * bulletList = [NSMutableString stringWithCapacity:items.count*30];
for (NSString * s in items)
{
[bulletList appendFormat:#"\u2022 %#\n", s];
}
textView.text = bulletList;
