I have created a html code like see above and the code uploaded to http://www.ged.Ic.com site.
Added an image name “1.jpg” into Xcode project.
When open iPad app loading http://www.ged.Ic.com/page/ from webview.
How to get to set image from into Xcode project to img src="image path from xcode"
NSString *imageFileName = #"image";
NSString *imageFileExtension = #"png";
NSString *imagePath = [[NSBundle mainBundle] pathForResource:imageFileName ofType:imageFileExtension];
NSString *imgHTMLTag = [NSString stringWithFormat:#"<img src=\"file://%#\" />", imagePath];
NSString *imageUrlString = #"http://www.gstatic.com/translate/intl/ru/logo.png";
NSString *yourText = #"Some text here";
NSString *htmlString = [NSString stringWithFormat:#"<img src='%#'/><br><b>%#</b>", imageUrlString, yourText];
[myWebView loadHTMLString:htmlString baseURL:nil];

Unable to read Images from xcode project for example.
drag and drop one image to xcode project, then read using following code.
__weak NSString *strTemp = [NSString stringWithFormat:#"%#/s_%#",[[NSBundle mainBundle] resourcePath],[[self.arr_gallery objectAtIndex:i]valueForKey:#"filename_larger"]];
strTemp = [strTemp substringToIndex:[strTemp length]-3];
strTemp = [NSString stringWithFormat:#"%#png",strTemp];
// NSString *strTemp = [[NSString alloc] initWithFormat:#"%#/s_BGP001#2x.png",[[NSBundle mainBundle] resourcePath]];
UIImage *image;
image = [[UIImage alloc] initWithContentsOfFile:strTemp];
img.image = image;
strTemp = nil;
Write following code.
NSString *newStrTemp = [strTemp stringByReplacingOccurrencesOfString:#"jpg" withString:#"png"];
Instead of this one.
strTemp = [strTemp substringToIndex:[strTemp length]-3];
strTemp = [NSString stringWithFormat:#"%#png",strTemp];
I have implemented the PinInterest through web view using this code:
NSString *description = #"Post your description here";
NSURL* sUrl = [NSString stringWithFormat:#"http://4.bp.blogspot.com/-w4oTZjlpgwo/T5_pi-KJPuI/AAAAAAAAAoM/rKm3E0XCbgY/s1600/red_rose_flower3.jpg"];// pass your link here with your image name
// NSLog(#"URL:%#", sUrl);
NSString *protectedUrl = ( NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,( CFStringRef)sUrl, NULL, (CFStringRef)#"!*'\"();:#&=+$,/?%#[]% ",CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)));
NSLog(#"Protected URL:%#", protectedUrl);
NSString *imageUrl = [NSString stringWithFormat:#"\"%#\"", sUrl];
imageUrl=[[NSBundle mainBundle]pathForResource:mAppDelegate.imagename ofType:nil];
NSString *buttonUrl = [NSString stringWithFormat:#"\"http://pinterest.com/pin/create/button/?url=www.flor.com&media=%#&description=%#\"", protectedUrl, description];
NSMutableString *htmlString = [[NSMutableString alloc] initWithCapacity:1000];
[htmlString appendFormat:#"<html> <body>"];
[htmlString appendFormat:#"<p align=\"center\"><img border=\"0\" src=\"http://assets.pinterest.com/images/PinExt.png\" title=\"Pin It\" /></p>", buttonUrl];
[htmlString appendFormat:#"<p align=\"center\"><img width=\"300px\" height = \"400px\" src=%#></img></p>", imageUrl];
[htmlString appendFormat:#"<script type=\"text/javascript\" src=\"//assets.pinterest.com/js/pinit.js\"></script>"];
[htmlString appendFormat:#"</body> </html>"];
return htmlString;
And I have also tried using PinInterest iOS SDK, but all I found is that can only pin the image from url.
And I need to pin image from local bundle image. Any help will be greatly appreciated.
Read the document once, they said Right now, "we only support pinning an image from a url. In the future, we’ll add support for pinning local images." i think this answers your question. for more clarification reed this. hope this helps :)
I am using ID3Lib example project to edit Title, Album and Artist ID3 tags on mp3 files and all is good until I come to adding an image (cover Art) if any one has any ideas how to finish off the below code that would be great:
- (void)demo {
nImage = [UIImage imageNamed:#"amazing-grace.jpg"];//unused
NSString *imagePath = [[NSBundle mainBundle] pathForResource:#"amazing-grace" ofType:#"jpg"];
NSString *path = [[NSBundle mainBundle] pathForResource:#"amazing-grace-10s" ofType:#"mp3"];
NSArray *docPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docPath = [[docPaths objectAtIndex:0] stringByAppendingPathComponent:#"amazing-grace-10s.mp3"];
[[NSFileManager defaultManager] copyItemAtPath:path toPath:docPath error:nil];
// Read title tag
ID3_Tag tag;
tag.Link([path UTF8String]);
ID3_Frame *titleFrame = tag.Find(ID3FID_TITLE);
unicode_t const *value = titleFrame->GetField(ID3FN_TEXT)->GetRawUnicodeText();
NSString *title = [NSString stringWithCString:(char const *) value encoding:NSUnicodeStringEncoding];
NSLog(#"The title before is %#", title);
// Write title tag
tag.Link([docPath UTF8String]);
tag.Strip(ID3FID_TITLE);
tag.Strip(ID3FID_ALBUM);
tag.Strip(ID3FID_LEADARTIST);
tag.Clear();
ID3_Frame frame;
frame.SetID(ID3FID_TITLE);
frame.GetField(ID3FN_TEXTENC)->Set(ID3TE_UNICODE);
NSString *newTitle = nTitle;
frame.GetField(ID3FN_TEXT)->Set((unicode_t *) [newTitle cStringUsingEncoding:NSUTF16StringEncoding]);
ID3_Frame frame2;
frame2.SetID(ID3FID_ALBUM);
frame2.GetField(ID3FN_TEXTENC)->Set(ID3TE_UNICODE);
NSString *newAlbum = nAlbmum;
frame2.GetField(ID3FN_TEXT)->Set((unicode_t *) [newAlbum cStringUsingEncoding:NSUTF16StringEncoding]);
ID3_Frame frame3;
frame3.SetID(ID3FID_LEADARTIST);
frame3.GetField(ID3FN_TEXTENC)->Set(ID3TE_UNICODE);
NSString *newArtist = nArtist;
frame3.GetField(ID3FN_TEXT)->Set((unicode_t *) [newArtist cStringUsingEncoding:NSUTF16StringEncoding]);
//this is the image code
ID3_Frame frame4;
frame4.SetID(ID3FID_PICTURE);
frame4.GetField(ID3FN_TEXTENC)->Set(ID3TE_UNICODE);// dont think this should be TEXTENC
NSString *newImage = imagePath;
frame4.GetField(ID3FN_DATA)->FromFile((const char *)[newImage cStringUsingEncoding:NSUTF16StringEncoding]);//this line is also probably wrong
tag.AddFrame(frame);
tag.AddFrame(frame2);
tag.AddFrame(frame3);
tag.AddFrame(frame4);
tag.SetPadding(false);
tag.SetUnsync(false);
tag.Update(ID3TT_ID3V2);
NSLog(#"The title after is %# The album after is %# The artist after is %# The artist after is %#", newTitle,newAlbum,newArtist,newImage);
}
Use file path with UTF-8 encoding and will work fine:
frame.GetField(ID3FN_DATA)->FromFile((const char *)[newImage cStringUsingEncoding:NSUTF8StringEncoding]);
I get this code, From this source: https://android.googlesource.com/platform/external/id3lib/+/8a58cac9f8db5ed55b02b3ac24156d628af923d1/examples/test_pic.cpp
frame.SetID(ID3FID_PICTURE);
frame.GetField(ID3FN_MIMETYPE)->Set("image/jpeg");
frame.GetField(ID3FN_PICTURETYPE)->Set(11);
frame.GetField(ID3FN_DESCRIPTION)->Set("B/W picture of Saint-Saëns");
//frame.GetField(ID3FN_DATA)->FromFile("composer.jpg");
frame.GetField(ID3FN_DATA)->FromFile((const char *)[newImage cStringUsingEncoding:NSUTF8StringEncoding]);
tag.AddFrame(frame);
And! this work nice. :D
i am trying to get the path to a certain file
and then open it in a webview. so i need to replace each space by '%20'
NSString *test=#"filename";
NSString *finalPath12 = [test stringByAppendingString:#".pdf"];
NSString *path1 = [[NSBundle mainBundle] bundlePath];
NSString *finalPath1 = [path1 stringByAppendingPathComponent:finalPath12];
NSString *file =#"file://";
NSString *htmlfilename1 = [file stringByAppendingString:finalPath1];
NSString *pathtofile = [htmlfilename1 stringByReplacingOccurrencesOfString:#" " withString:#"%20"];
any string is working except #"%20".
this works perfectly for exemple:
NSString *pathtofile = [htmlfilename1 stringByReplacingOccurrencesOfString:#" " withString:#"string"];
but i need the #"%20". What am i missing ? Thanks
There is already [NSString stringByAddingPercentEscapesUsingEncoding:] (reference) for that very purpose.
However in your case, as you want a URL, you can replace all the lines in your question with:
NSURL *url = [[NSBundle mainBundle] urlForResource:#"filename" withExtension:#"pdf"];
You need to use #"%%20".
As first % is treated as escape/wild character.
Or use
stringByAddingPercentEscapesUsingEncoding:
I am trying to load the image(png) in UIWebview. But I got the following error
""ImageIO: PNGinvalid literal/lengths set"
I will get the "png" from the web service. I will store it in the following path. "Users/XXX/Library/Application Support/iPhone Simulator/4.3.2/Applications/E4DE3097-EA84-492F-A2A7-5882202F3B00/Documents/attachement.png "
When I reading the file from the path, I got the error. I am using the following code
NSBundle *bundle = [NSBundle mainBundle];
NSString *path = [bundle bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
NSString *commentHtml = [NSString stringWithFormat:#"<img src=\"%#\"/>", documentEntity.path];
NSString *html3 = [NSString stringWithFormat:#"<html><head/><body><div><b>COMMENTS:</b></div>%#</body></html>", commentHtml];
[self.documentView loadHTMLString:html3 baseURL:baseURL];
Please help me.
THanks

If you have saved the Image in Documents Folder, why are you fetching from MainBundle.
Fetching Image from the Documents Directory would be :
NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *aFilePath = [NSString stringWithFormat:#"%#/attachement.png", aDocumentsDirectory];
UIImage *anImage = [UIImage imageWithContentsOfFile:aFilePath];
