Hi I'm trying to put an arrow into a UILabel's text but it is not working. I'm trying the following code
NSString *labeltext = #"➜";
label.text = labeltext;
But that makes the app crash!
(if you go to the edit menu and go to special characters then it is the 10th rightwards arrow)
.
Thanks for your help in advance
Code should be working by just writing the special character directly in the code as written in the question also
label.text=#"➜";
but in case it is not working then there are alternative ways to print the special characters in IOS, You need to use Unicode character of this sign , check out this page codes and after getting the code just do like as follows
UniChar ucode = 0x2794;
NSString *codeString = [NSString stringWithCharacters:&ucode length:1];
[label setText:codeString];
OR Just write directly like as follows
label.text=#"\u2794"; // this is the unicode for right arrow
in Swift:
lable.text="\u{2794}"

I am going to develop the iPhone app. But I got stuck with one place. I want to write some symbol on the label from the xib file.
The symbols are not on the keyboard but we can get it by the ASCII value.
e.g: the ACSII value for the character sign "mue" is 230 but how to print that symbol "mue" on the label that i dont know.
So please help me for that.
Thanks in advance.
Use whatever editor you like to produce that character, and open your xib in XCode and just copy/paste it in?
Use NSUTF8StringEncoding to encode your string.
For example,
NSString *str = [NSString stringWithUTF8String:"your string for encoding"];
[lblName setText:str];
Following function will also help :
- (NSString *) decodedString:(NSString *) originalString {
NSString *newString = [NSString stringWithUTF8String:[originalString cStringUsingEncoding:[NSString defaultCStringEncoding]]];
return newString;
}
I suggest to use above function.
Pressing Cmd+Ctrl+Space will open a special characters menu. Check if the desired symbol is present. If it isn't, click the gear icon, then select the desired category — add it to the list.
See screenshot below
I think you mean the character 'µ', yes?
If so, you can simply type it into the label by clicking "option" and "m" on your Macintosh keyboard, when you are editing the label in your XIB.
If you can use the unicode number instead, you can do it like this:
NSString *muString = [NSString stringWithFormat:#"%C", 0x03BC];
Write 0x then the unicode number.
Open the "Special Characters"-Panel and search for your character. You can find it at the bottom of the edit menu. There is a shortcut for it too, cmd+opt+t
Copy and paste your character from there to your UILabel.
and btw: option + m = µ
You can simply type into label by using 'Alt' key + 'm' key on key board, when you are editing the label in your XIB and rest of symbols, you can get easily using 'Alt' key and other keys. You can fix 'Alt' key and change other keys(one by one).
Is it possible to replace a word with emoticons?
For example
NSString *myString = #"I am sad of him"
now i want to check the word whether it contains the word "sad", if it has i want to replace that word with sad emoticons.
I am not sure how to have emoticons in the nsstring
Please let me know
yeah, you can do this using this:
myString = [NSString stringByReplacingOccurrencesOfString:#"sad" withString:#"\ue058"];
Check this link for emoji codes: (replace the &#x with \u though)
http://barrow.io/posts/iphone-emoji/
you can use NSAttributed String to show emotion icon but before that you have to search "sad" word in whole paragraph by using normal search method. :)
How do I add a rupee symbol in a UILabel on the iPhone?
Here is How I've done this by using Unicode Character It's working and tested by me.
NSString *rupee=#"\u20B9";
NSLog(#"print rupee symbol %#",rupee);
Please refer this link UniCode Character
For Swift Language you should try!
let rupee = "\u{20B9}"
println(rupee)
// for Swift >2.0
let rupee = "\u{20B9}"
print(rupee)
more about UniChar you should check this Official Apple Doc Cheers :)
Rupee symbol is available as part of the platform itself. Go to Edit > Special Characters > Currency Symbols.
When I used it first, I was under the impression that this is part of the menu options of Xcode, but right now while I am typing here on this page opened in Firefox and I go to Edit menu, I see the same Special characters option in the menu so probably it is part of OSX itself. Just drag and drop it anywhere on the storyboard where you want this symbol to appear. I'm just dragging and dropping the same here, let's see whether it appears here or not!
₹
This integration of special characters in osx is pretty handy and also has many variations for that special character (rupee symbol in this case)
Yups, Parth is right just copy and paste the rupee symbol (₹) to NSString and you are done.
In Swift 4
let RSlabel = UILabel()
let cost = 1000
override func viewDidLoad() {
super.viewDidLoad()
RSlabel.text = "\u{20B9}"+"\(cost)"
print(RSlabel,"RSlabel")
}
May be you will have to find some language which has a similar symbol.
Or you can just copy the Rupee symbol from somewhere (like from some soft-copy document which contains that) and paste it directly from there into your UILabel text.
As for now I don't know any other way apart from this as present keyboards dont have a Rupee symbol as yet. May be in future it would be having that :)
Hope this helps you
Go to
Edit -> Emoji & Symbols
In Xcode 7, the symbols location has been changed a bit from what has been suggested by Atul.
Go through the below SO post,
Localize Currency for iPhone
Edited:
you could also go with the approach of having rupee symbol as an UIImageView and show it before OR after a UILabel view.
Please see the reference code :
Have below in .h file...
UIView* iContainerView;
UIImageView* iRupeeSymbol;
UILabel* iAmountLabel;
And your .m file would be like below.
iRupeeSymbol= [[UIImageView alloc] initWithImage:myRupeeImage];
iAmountLabel.text = #"55555";
[iContainetView addSubview:iRupeeSymbol];
[iContainetView addSubview:iAmountLabel];
[self.view addSubview:iContainetView];
And set the appropriate frame value for all three views,
I retrieve an NSString from a Property list and display it in a UILabel. The NSString already includes \n s, however the UILabel just displays them as text. How can I tell the UILabel to actually use the \n s as line breaks?
Everything you type into a plist in the plist editor is interpreted as plain text. Try it... put a ' into a field and right click -> view as "plain text" and you'll see it substitutes it for '. Therefore you can't put \n into a plist because it thinks you're just typing text and will treat it as such. Instead of putting \n into your plist use Alt+Enter to get your newline. If you view this as a text file now you'll see \ns printed and new lines acctually shown in the text file.
Now when you output it it won't display \n it will just give it a new line.
Plus, as has been mentioned UITextField is only one line anyway and you probably would benefit from using UITextView.
Well, first, you are going to need a string that you can modify. To accomplish that, you can simply do:
NSMutableString* correctedPath = [path mutableCopy];
At that point, you can use -insertString:atIndex: to insert any characters you need.
You're using the wrong class here.
UITextField doesn't (for all that I know) support multi-line input. For that, you will need a UITextView (it has editing enabled by default). It should interpret \n's without any problems. It also has a lineBreakMode property, if you want to make use of that.
I'm having a problem trying to convert a character into a string in Xcode. Here's my code...
NSString *temp = [NSString stringWithFormat:#"%# %# %# = %#", inputOne.text, sign.text, inputTwo.text, answer.text];
self.sign.text is supposed to return either a "+", "-", "*", or "/", which it does. However, I'm trying to have the user post one of these back into facebook via the app. All but the "+" sign will load as a string when they post it to their wall. I don't understand how to get the "+" to show.
I'm guessing that this gets lost since the "+" has a different meaning in javascript. How can I make it a string character in my NSString so that it accepts when posting. Hope this made sense.
I know you can put a quotation mark into a textView by placing a "\" before the quotation. This may work with a "+" sign as well. So the string would look something like this:
#"This is a plus sign \+ in a textView"
Which would return
This is a plus sign + in a textView
Sending "+" over the net (e.g. in GET or, I think, POST) will convert "+" into a space character. To fix, you need to escape the "+" using "%2B".
