I tried something like
//Putting the sentence into array
NSString *list = (#"A book costs £50., Ken has saved £45., How much more does he need to save to buy the book?");
NSArray *listItems = [list componentsSeparatedByString:#", "];
But the result wasn't what I want. I want each frame will contain a word. eg [A] [book] [costs] ...etc
// to create a frame
CGRect frame= CGRectMake(50, 60, 50, 50);
comp *newBox = [[comp alloc] initWithFrame:frame ];
[self.view addSubview:newBox];
newBox.backgroundColor=[UIColor blueColor]
This frame work fine, i just need to put the word in to each frame
Try this
NSString *list = (#"A book costs £50. Ken has saved £45. How much more does he need to save to buy the book?");
NSArray *listItems = [list componentsSeparatedByString:#" "];

How to create a UILabel or UITextView with bold and normal text in it?
(5 answers)
Closed 9 years ago.
Is it possible to convert a NSString to html and set as a label?
The code below shows the NSString I want to set finalPrice as bold text and finalStr&shipping string as normal text
NSString *myText = [NSString
stringWithFormat:
#"%#\nFinal price including $%.2f Shipping and all discount: <b>$%.2f</b>",
finalStr,shipping,finalPrice];
lbl.text = myText;
I want to set multiple color and multiple text type into same dyanamic label.
use following label for bold effects. Or you can get code from that class.
DAAttributedStringUtils
and also see this
Different Label
Edit
NSString *myText = [NSString stringWithFormat:#"%#\nFinal price including $%.2f Shipping and all discount: %%B$%.2f%%b",finalStr,shipping,finalPrice];
DAAttributedLabel* lbl = [[DAAttributedLabel alloc] initWithFrame:CGRectMake(30.0f, 30.0f, 260.0f, 24.0f)];
lbl.backgroundColor = [UIColor colorWithRed:0.9f green:0.9f blue:1.0f alpha:1.0f];
lbl.text = (id)[formatter formatString:myText];
[self.view addSubview:lbl];
Try using NSAttributedString
There are already several questions around this here like
How do you use NSAttributedString?
NSString * textString = #"Hello Bold";
NSInteger _stringLength = [textString length];
NSMutableAttributedString * attString = [[NSMutableAttributedString alloc] initWithString:textString];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica" size:14.0f]; range:NSMakeRange(0, _stringLength)];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica-Bold" size:14.0f]; range:NSMakeRange(6, 4)];
myLabel.attributedText = attString;
(code not tested)
Edit:
label.attributedText is only available for iOS 6.0+
FYI, the answer above suggesting the use of DAAttributedStringUtils and DAAttributedLabel didn't mention that these are convenience classes for the use of NSAttributedString. They make formatting NSAttributedString instances a little easier. As an example, here's how to do the same formatting described about by HAS using DAAttributedStringUtils:
float finalPrice = 34.99, shipping = 4.99;
// Setup the formatter
DAAttributedStringFormatter* formatter = [[DAAttributedStringFormatter alloc] init];
formatter.defaultFontFamily = #"Georgia";
formatter.defaultFontSize = 12.0f;
formatter.colors = #[ [UIColor blackColor], [UIColor redColor] ];
NSAttributedString* attrStr = [formatter formatString:#"%0C%0FRed Courier Text %1C%1FBlue Arial Text %0CRed Arial Text"];
// setup base strings
NSString *finalStr = #"Some Text. ";
NSString *shippingAttributed = [NSString stringWithFormat:#"%%B%%1C$%.2f%%b%%c", shipping];
NSString *middleText0 = #"Final price including ";
NSString *middleText1 = #" Shipping and all discount: ";
NSString *finalPriceAttributed = [NSString stringWithFormat:#"%%B%%1C$%.2f%%b%%c", finalPrice];
// Format the strings
self.label.attributedText = [formatter formatString:[NSString stringWithFormat:#"%#%#%%B%%1C%#%%b%%c%#%%B%%1C%#", finalStr, shippingAttributed, middleText0, middleText1, finalPriceAttributed];
Somewhat less code, and I think easier to understand. FYI, the formatter string in the last line contains codes that are used to modify the format of portions of the string. Those codes use double percents (
How can I obtain the attributes of an NSAttributedString?
I thought using enumerateAttributesInRange:NSMakeRange(0, str.length) and then saving every attributes in a NSMutableDictionaries but I'd like to know if exists a better way.
EDIT------
My problem is that I have a NSAttributedString and i want to use this function on its attributes...
CTFramesetterSuggestFrameSizeWithConstraints(framesetter,range, __ATTRIBUTES__, size , NULL);
NSDictionary *attributesFromString = [string attributesAtIndex:0 longestEffectiveRange:nil inRange:NSMakeRange(0, string.length)];
UITextView *t = [[UITextView alloc] init];
[t setAttributedText:a];
t.typingAttributtes
I want more than one font color in the same UILabel. I dont know if it is possible. I dont really think so but maybe some of you out there have a smart solution for it? Maybe something like stringWithFormat. [NSString stringWithFormatAndColor: #"Text with color: %# %#", text, color, text, color]
This image illustrate what I'm trying to accomplish:
You can achieve this with NSAttributedSting. An easy to use drop-in replacement for UILabels with support for attributed strings is TTTAtributedLabel or OHAttributedLabel
In my experience it is easier to work with NSMutableAttributedStrings and build it up step by step.
NSMutableAttributedString *attrStr = [NSMutableAttributedString attributedStringWithString:#""];
NSMutableAttributedString *a = [NSMutableAttributedString attributedStringWithString:#"This is "];
[a setTextColor:aColorObj];
NSMutableAttributedString *b = [NSMutableAttributedString attributedStringWithString:#"only one "];
[b setTextColor:bColorObj];
NSMutableAttributedString *c = [NSMutableAttributedString attributedStringWithString:#"Label"];
[c setTextColor:cColorObj];
[attrStr appendAttributedString:a];
[attrStr appendAttributedString:b];
[attrStr appendAttributedString:c];
OHAttributedLabel *attributedTextLabel = [[OHAttributedLabel] initWithFrame:frame]
[attributedTextLabel setAttributedText:attrStr];
I'm trying to build words in arrays by their key value in a dictionary. However, it won't work the way I'd like it to, because I can't "copy" a UIImageView.
It would be PERFECT, if when adding the letter from the dictionary to an array, it gives me a copy instead of the real object. I don't want to make multiple images of the same letter and add it to the dictionary, because then I could no longer call it by key "s" or "a", and I need more than one array to use the same letters at at time.
What can I do?
//How I create the letters
char s = 's';
NSString *key = [NSString stringWithFormat:#"%c", s];
alphabetS = [[UIImageView alloc] init]];
[alphabetS setImage:[UIImage imageNamed:#"s.png"]];
[allTilesDictionary setObject:alphabetS forKey:key];
[alphabetS release];
//How I use the imageviews from the dictionary
NSMutableArray *wordOne = [[NSMutableArray alloc] initWithObjects:[allTilesDictionary objectForKey:#"s"],[allTilesDictionary objectForKey:#"h"],[allTilesDictionary objectForKey:#"o"],[allTilesDictionary objectForKey:#"p"], nil];
EDIT: My solution. It works perfectly.
for (UIImageView *letters in wordOne)
{
newLetter = [[UIImageView alloc] init];
newLetter.image = letters.image;
newLetter.userInteractionEnabled = YES;
//I can now either lay them out wherever I want on the view, or add them to a new array.
}
Your original code, slightly modified:
//How I create the letters
char s = 's';
NSString *key = [NSString stringWithFormat:#"%c", s];
[allTilesDictionary setObject:[UIImage imageNamed:#"s.png"] forKey:key];
//How I use the imageviews from the dictionary
NSMutableArray *wordOne = [[NSMutableArray alloc] initWithObjects:[allTilesDictionary objectForKey:#"s"],[allTilesDictionary objectForKey:#"h"],[allTilesDictionary objectForKey:#"o"],[allTilesDictionary objectForKey:#"p"], nil];
Your use of that code, slightly modified:
for (UIImage *letters in wordOne)
{
newLetter = [[UIImageView alloc] init];
newLetter.image = letters;
newLetter.userInteractionEnabled = YES;
//I can now either lay them out wherever I want on the view, or add them to a new array.
}
No unnecessary UIImageViews created.
for (UIImageView *letters in wordOne)
{
newLetter = [[UIImageView alloc] init];
newLetter.image = letters.image;
newLetter.userInteractionEnabled = YES;
//I can now either lay them out wherever I want on the view, or add them to a new array.
}
I'm looking for a way to dynamically create NSString objects in objective C based on how many of them I need (between 1 and 5). I then want to use those strings as names of objects which also are dynamically created;
Pseudo Code:
for (i=1, i <= number_of_characters, i++)
{
NSMutableString* theString = [NSMutableString character];
[theString appendString:[NSString stringWithFormat:#"%i ",i]];
UILabel *theString;
[theString release];
}
and I am hoping to get several UILabel objects named:
character1
character2
character3
and so on...
Thanks!
You can create UILabel objects on the fly, but you can't create variables at runtime. If you want to set the text of the label to theString, that's no problem:
NSMutableArray *labels = [NSMutableArray array];
for (i=1, i <= number_of_characters, i++)
{
NSMutableString* theString = [NSString stringWithFormat:#"%i ",i];
UILabel *label = [[UILabel alloc] initWithFrame:someCGRect];
label.text = theString;
[labels addObject:label];
[theString release];
}
Now you've got an array full of labels, each of which has a number as its text. The labels haven't been added to any view yet, so you'll want to take care of that.
