I have a NSTextView which contains some text with attributes (syntax highlighting). I'm trying to have a copy option which keeps the syntax highlighting so that I can paste it into a gmail text window. Currently the highlighting does not appear when I copy paste it, however if I were to copy the following section directly from this stackoverflow page:
- (void) copyAsRTF
{
NSPasteboard *pateboard = [NSPasteboard generalPasteboard];
NSData * rtfData = [[self textStorage] RTFFromRange: [self selectedRange]
documentAttributes: nil];
if (rtfData)
{
NSString * test = [[NSString alloc] initWithData: rtfData
encoding: NSUTF8StringEncoding];
[pateboard declareTypes: #[NSRTFPboardType]
owner: self];
[pateboard setData: rtfData
forType: NSRTFPboardType];
} // End of we had data
} // End of copyAsRTF
And paste it into gmail, it will paste with full syntax highlight no problem. The above code is what I use for generating my RTF code and I can confirm that it does generate proper RTF as I have a test variable being generated.
Any ideas what I am doing wrong here? To my understanding this SHOULD work.
(I should note that I have tried in multiple browsers - Chrome, Safari and Firefox).
As discovered in comments, in order to be working in chrome, you need to copy your text as html (public.html pasteboard type) or probably both html an rtf types.
Based on the comments with #Sega-Zero, I came up with the following (a bit sloppy, but it does the trick). For my specific needs, the html color & font should match the attributed string, so I enumerate that and create an html variable. This works in Safari, Chrome and Firefox.
#define PasteBoardTypeHTML #"public.html"
- (void) copyAsRTF
{
NSPasteboard *pasteboard = [NSPasteboard generalPasteboard];
// Get our RTF data
NSData * rtfData = [[self textStorage] RTFFromRange: [self selectedRange]
documentAttributes: nil];
// Get the HTML for our current data
NSData *htmlData = [[self htmlForRange: self.selectedRange] dataUsingEncoding: NSUTF8StringEncoding];
NSMutableArray * clipboardTypes = [NSMutableArray array];
if (nil != rtfData)
{
[clipboardTypes addObject: NSPasteboardTypeRTF];
} // End of we have rtf
if(nil != htmlData)
{
[clipboardTypes addObject: PasteBoardTypeHTML];
} // End of we have html
// Set our pasteboard types (types need to be declared before we call setData).
[pasteboard declareTypes: clipboardTypes.copy
owner: self];
if (rtfData)
{
[pasteboard setData: rtfData
forType: NSPasteboardTypeRTF];
} // End of we have rtf
if(htmlData)
{
[pasteboard setData: htmlData
forType: PasteBoardTypeHTML];
} // End of we have html
} // End of copyAsRTF

This code had been working fine until just recently. I hadn't' changed anything nor upgraded my system and I'm completely flummoxed.
I've been using it for 6 years and now it dies on me.
Is there an easier or better way of running an applescript from within a cocoa application? At this point I'm happy to pay to fix this problem!

Easier, yes, although whether that’s your actual problem is another question.
http://appscript.sourceforge.net/asoc.html
I assume you’ve already got other details, including sandboxing and hardening settings and plist entries, taken care of. (Recent Xcode upgrades also had a habit of breaking it when auto-upgrading your project files, by turning on hardening for you so Apple events can’t get out.)
I´m trying to make the AVSpeech speak up two NSString in the string *combine and pas it to AVSpeech. But it´s only *speekone that get passed to the *combine string. So I only ge the first string spoken. Am I declaring the string wrong somehow or do I need to change my method?
- (IBAction)UIButtonPlayPressed:(UIButton *)sender{
NSString *speekone = _activity.activityName;
NSString *speektwo = _activity.activityDescription;
NSString *combined = [NSString stringWithFormat:speekone, speektwo];
if (speechPaused == NO) {
//Title for button [self.UIButtonPlay setTitle:#"Pause" forState:UIControlStateNormal];
[self.synthesizer continueSpeaking];
speechPaused = YES;
NSLog(#"playing");
} else {
//Titleforbutton [self.UIButtonPlay setTitle:#"Play" forState:UIControlStateNormal];
speechPaused = NO;
[self.synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];
NSLog(#"paused");
}
if (self.synthesizer.speaking == NO) {
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:combined];
[self.synthesizer speakUtterance:utterance];
The first argument to your stringWithFormat is not a format specifier.
This line:
NSString *combined = [NSString stringWithFormat:speekone, speektwo];
should become:
NSString *combined = [NSString stringWithFormat:#"%# %#", speekone, speektwo];
I am fresher to iOS, i am getting problem at checking string object contains URL or string?
NSMutableArray *Arr=[NSMutableArray alloc]initWithObject:#"Welcome", #"http://abcd.com/Images/bus.png", nil];
int i;
i++;
NSString *str=[Arr objectAtIndex:i];
Now, i want to check condition, if string contains "Welcome", have to display on label or if it is URL , i need to display that URL image in ImageView. So how can i check it? Please help me in this problem.
Instead of initiating both as NSStrings, try differentiating between them by making urls a NSURL (special container specifically for urls):
NSMutableArray* Arr = [NSMutableArray alloc]initWithObject:#"Welcome", [NSURL URLWithString:#"http://abcd.com/Images/bus.png"], nil];
for(id object in Arr)
{
if([object isKindOfClass:[NSString class]])
{
NSString* string = object;
NSLog(#"String: %#", string);
}
else if([object isKindOfClass:[NSURL class]])
{
NSURL* url = object;
NSLog(#"URL: %#", url);
}
}
Try like this
NSMutableArray *Arr=[[NSMutableArray alloc]initWithObjects:#"Welcome", #"http://abcd.com/Images/bus.png",nil];
NSString *st=nil;
for(NSString *string in Arr)
{
NSArray *matches = [detector
matchesInString:string
options:0
range:NSMakeRange(0,
[string length])];
for (NSTextCheckingResult *match in
matches) {
if ([match resultType] ==
NSTextCheckingTypeLink) {
NSURL *url = [match URL];
} else
{
NSlog(#"it is a string");
}
}
}
Try this, it will help you:
NSMutableArray *Arr=[[NSMutableArray alloc]initWithObjects:#"Welcome", #"http://abcd.com/Images/bus.png", nil];
if([Arr count])
{
for (NSString *str in Arr)
{
if([str isEqualToString:#"Welcome"])
{
NSLog(#"str is %#",str);
//do whatever you want
}
if([str isEqualToString:#"http://abcd.com/Images/bus.png"])
{
NSLog(#"str is %#",str);
//do whatever you want
}
}
}
To check NSString is containing a URL You can Try This code
if ([stringName hasPrefix:#"http://"] || [stringName hasPrefix:#"https://"]) {
//show imageVivew
}
I'm trying to append the file extension to a the stringValue returned by a subclassed NSTextFieldCell
I've tried everything I knew and could find on the internet, but this is just giving me a headache
the method is the following:
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
NSMutableString *filename = [[NSMutableString alloc] init];
[filename appendString:self.stringValue];
NSString *iconFileName = [[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:filename] stringByAppendingPathExtension:#"png"];
NSLog(#"%#", iconFileName);
}
The returned value is without the extension though!
I've also tried the following:
filename = [NSString stringWithFormat: #"%#.png", filename];
This returns the "filename" string without the ".png"
Similarly:
filename = [filename stringByAppendingString: #".png"];
returns just the "filename"
The table column where this cell belongs to is bound to an NSObject, and the method that sends the data to the column is the following:
- (NSString *) nationString {
NSMutableString *string = [[NSMutableString alloc] init];
int index = 0;
if (nationAddress && nationAddress > 0x0) {
index = [[[[controller database] nationsAddressIndex] valueForKey:[NSString stringWithFormat:#"%lli", nationAddress]] intValue];
Nation *nationality = [[[controller database] nations] objectAtIndex:index];
[string appendString:[nationality name]];
}
else {
[string appendString:#"---"];
}
return string;
}
Anyone has any idea why this might be happening, or can suggest any alternatives?
Any help will be appreciated
Thanks
This should return the complete path with extension:
NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"Default.png"];
NSLog(#"%#", path);
So, assuming self.stringValue includes the extension, your method should work with this:
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
NSString *iconFileName = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:self.stringValue];
NSLog(#"%#", iconFileName);
}
If it doesn't include the extension, try this:
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
NSString *strWithPath = [NSString stringWithFormat:#"%#.png", self.stringValue];
NSString *iconFileName = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:strWithPath];
NSLog(#"%#", iconFileName);
}
Just for test. Try to use this code and update here a output values:
NSMutableString *filename = [[NSMutableString alloc] init];
[filename appendString:self.stringValue];
NSLog(#"text1: %# ;", filename);
filename = [NSString stringWithFormat: #"%#.png", filename];
filename = [NSString stringWithFormat: #"%#.png%#", filename, filename];
NSLog(#"text2: %# ;", filename);
These should work (barring a typo):
NSString* filename = #"abc";
NSString* result1 = [NSString stringWithFormat:#"%#.png", filename];
NSString* result2 = [filename stringByAppendingString:#".png"];
NSMutableString* result3 = [filename mutableCopy];
[result3 appendString:#".png"];
If they don't appear to be working then you have some problem with how you're initializing or displaying your values.
Hint: Place an NSLog(#"The answer is %#", resultN); statement immediately after each of the above (with "resultN" changed appropriately) to see what you're getting. Keep in mind that if you look from a different object you may be looking at different variables.
I have developed in C but am quite new to Objective-C and iPhone app development. I am working on an app that needs to strip the punctuation off a string. The function works but when I analyse the code it flags up some issues around one of the NSstrings I am using.
I don't understand why and therefore don't know how to fix it.
The code for the main function along with the analyser warning is:
- (IBAction)doIt {
NSString *start_punct = [[NSString alloc] init];
NSString *end_punct = [[NSString alloc] init];
NSString *actual_word = [[NSString alloc] init];
outputTextTextView.text = translatedText; //potential leak of an object alloctated on line xx and stored into 'actual word'
[translatedText release]; translatedText = nil;
[start_punct release]; start_punct = nil; //incorrect decrement of reference count of an object that is not owned at this point by the caller
[end_punct release]; end_punct = nil;
[actual_word release]; actual_word = nil; //this causes a crash
start_punct = [MainViewController getStartPunct:word start:&start_range_start len:&start_range_len];
end_punct = [MainViewController getEndPunct:word start:&end_range_start len:&end_range_len];
actual_word = [word substringWithRange: NSMakeRange(start_range_start,(end_range_start-start_range_start)+1)];
}
The code for the getStartPunct and getEndPunct functions is below
+(NSString*) getStartPunct:(NSString*) inputString
start:(NSInteger*)rangeStart
len:(NSInteger*)length {
NSString* start_str = nil;
NSRange firstAlphanumCharFromStart = [inputString rangeOfCharacterFromSet:[NSCharacterSet alphanumericCharacterSet]];
if (firstAlphanumCharFromStart.location != NSNotFound) {
start_str = [inputString substringWithRange: NSMakeRange(0, firstAlphanumCharFromStart.location)];
*length = firstAlphanumCharFromStart.length;
*rangeStart = firstAlphanumCharFromStart.location;
} //if
if (start_str == nil) {
*length=0;
*rangeStart=0;
}
return start_str;
} //getStartPunct
+(NSString*) getEndPunct:(NSString*) inputString
start:(NSInteger*)rangeStart
len:(NSInteger*)length {
NSString* end_str = nil;
NSInteger rnge = inputString.length;
NSCharacterSet* CS = [NSCharacterSet alphanumericCharacterSet];
NSRange firstNonAlphanumCharFromEnd = [inputString rangeOfCharacterFromSet:CS options:NSBackwardsSearch];
if (firstNonAlphanumCharFromEnd.location != NSNotFound) {
end_str = [inputString substringWithRange: NSMakeRange(firstNonAlphanumCharFromEnd.location+1, rnge - firstNonAlphanumCharFromEnd.location-1)];
*length = firstNonAlphanumCharFromEnd.length;
*rangeStart = firstNonAlphanumCharFromEnd.location;
} //if
if (end_str == nil) {
*length=0;
*rangeStart=0;
}
return end_str;
} //getEndPunct
Can someone see what the issue is? I'm sure it is something very basic..
Many Thanks in advance!
Thanks for all the responses so far.
adpalumbo you are right, I had paste the elements in the wrong order. The correct order is below and I have changed the initialization as suggested by Alex Nichol.
This has fixed 1 of the warning but the others (as shown below) still remain and I don't understand why 'start_punct' and 'end_punct' are behaving differently
- (IBAction)doIt {
NSString *start_punct = nil;
NSString *end_punct = nil;
NSString *actual_word = nil;
start_punct = [MainViewController getStartPunct:word start:&start_range_start len:&start_range_len]; // method returns objective with +0 retain count
end_punct = [MainViewController getEndPunct:word start:&end_range_start len:&end_range_len];
actual_word = [word substringWithRange: NSMakeRange(start_range_start,(end_range_start-start_range_start)+1)];
[translatedText release]; translatedText = nil;
[start_punct release]; start_punct = nil; //incorrect decrement of reference count
[end_punct release]; end_punct = nil;
//[actual_word release]; actual_word = nil; //possible abend
}
