it shows null .custom keyboard image send via textdocumentproxy.
NSMutableAttributedString *mas;
NSTextAttachment* onionatt = [NSTextAttachment new];
onionatt.image = onions;
onionatt.bounds = CGRectMake(0,-5,onions.size.width,onions.size.height);
NSAttributedString* onionattchar = [NSAttributedString attributedStringWithAttachment:onionatt];
NSRange r = [[mas string] rangeOfString:#"onions"];
[mas insertAttributedString:onionattchar atIndex:(r.location + r.length)];
NSString *string =[NSString stringWithFormat:#"%#",mas];
[self.textDocumentProxy insertText:string];
You cannot send image via uitextdocumentproxy
In custom keyboard you have to copy the image in pasteboard and then manually paste into textfield by using this code:
NSString *shareImageName = #"cross.png";
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
UIImage *image = [UIImage imageNamed:shareImageName];
NSData *data = UIImagePNGRepresentation(image);
[pasteboard setData:data forPasteboardType:#"public.png"];

Is there anyone that can help me combine this
https://github.com/AndreyLunevich/DLImageLoader-iOS
With my code below... I am not understanding as my images are loaded from an NSString in core data and not a URL (maybe I cannot use this helper file)
My code is:
SCTableViewSection *Section3 = [self.tableViewModel sectionAtIndex:0];
Section3.cellActions.lazyLoad = ^(SCTableViewCell *cell, NSIndexPath *indexPath)
{
DLImageView *imageView = (DLImageView *)[cell viewWithTag:1];
NSString *imageString = (NSString *)[cell.boundObject valueForKey:#"thumbnail"];
NSString *fullName = [NSString stringWithFormat:#"Documents/%#", imageString];
NSString *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:fullName];
UIImage *originalImage = [UIImage imageWithContentsOfFile:imagePath];
NSLog(#"added image from lazyload");
// size of actual thumbnail to display in cell
CGSize destinationSize = CGSizeMake(154,95); // size of actual thumbnail
UIGraphicsBeginImageContext(destinationSize);
[originalImage drawInRect:CGRectMake(0,0,destinationSize.width,destinationSize.height)];
UIImage *thumbnail = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[UIView transitionWithView:imageView
duration:2.25f
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^{
imageView.image = thumbnail;
} completion:nil];
};
I have an image view and it pulls url from the internet this is the url that I got from the RSS Feed -
its an image pulled from rss feed .xml here is code I use to get image.
- (void)viewDidLoad {
[super viewDidLoad];
NSURL *URL = [NSURL URLWithString:#"www.something.com/rss/hi.xml"];
NSData *data = [NSData dataWithContentsOfURL:URL];
// Assuming data is in UTF8.
NSString *string = [NSString stringWithUTF8String:[data bytes]];
NSString *webStringz = string;
NSString *mastaString;
mastaString = webStringz;
NSScanner *theScanner2;
NSString *imageURL2;
theScanner2 = [NSScanner scannerWithString: mastaString];
// find start of tag
[theScanner2 scanUpToString: #"<media:content url=\"" intoString: nil];
if ([theScanner2 isAtEnd] == NO) {
// find end of tag
[theScanner2 scanUpToString: #"\" " intoString: &imageURL2];
imageURL2 = [imageURL2 stringByReplacingOccurrencesOfString:#"<media:content url=\"" withString:#""];
imageURL2 = [imageURL2 stringByReplacingOccurrencesOfString:#"\n" withString:#""];
imageURL2 = [imageURL2 stringByReplacingOccurrencesOfString:#" " withString:#""];
//Download Image
NSURL * imageURL = [NSURL URLWithString:[imageURL2 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation([UIImage imageWithData:[NSData dataWithContentsOfURL:imageURL]])];
UIImage * image = [UIImage imageWithData:imageData];
[imageView setImage:image];
NSLog(#"Image URL #1: %#", imageURL2);
mastaString = [mastaString stringByReplacingOccurrencesOfString:imageURL2 withString:#""];
if (imageView.image == nil) {
NSLog(#"IS NIL");
}
else if (image == nil) {
NSLog(#"IS NIL");
}
// Do any additional setup after loading the view.
}
}
In my NSLOG it says the image url and its valid.
It DOES NOT show the IS NIL
It DOES NOT show the IS NIL 2
But the ImageView is not showing the image? Why? Its all linked up and everything?
Thanks
It must be that you didn't create the image view when the first time you access the view of UIViewController. Note that self.view will trigger viewDidLoad method if it is nil, but then the imageView is nil. So you'b better create the imageView in viewDidLoad method.
I'm new to cocoa and programming, sorry if this is something basic.
I'm using ARC. I have an NSImageView component, which is controlled by DropZone class. I drag & drop an image into it, but once I try to call in the scalling method I got, it tells me that the ": ImageIO: CGImageSourceCreateWithData data parameter is nil" I assume I'm doing something wrong, just don't know what yet.
Here's my method in DropZone.m
- (void)scaleIcons:(NSString *)outputPath{
NSImage *anImage;
NSSize imageSize;
NSString *finalPath;
anImage = [[NSImage alloc]init];
anImage = image;
imageSize = [anImage size];
imageSize.width = 512;
imageSize.height = 512;
[anImage setSize:imageSize];
finalPath = [outputPath stringByAppendingString:#"/icon_512x512.png"];
NSData *imageData = [anImage TIFFRepresentation];
NSBitmapImageRep *rep = [NSBitmapImageRep imageRepWithData:imageData];
NSData *dataToWrite = [rep representationUsingType:NSPNGFileType properties:nil];
[dataToWrite writeToFile:finalPath atomically:NO];
}
The DropZone.h
#interface DropZone : NSImageView <NSDraggingDestination>{
NSImage *image;
}
- (void)scaleIcons:(NSString *)outputPath;
#end
And here's how I call it it my AppDelegate.m
- (IBAction)createIconButtonClicked:(id)sender {
NSFileManager *filemgr;
NSString *tempDir;
filemgr = [NSFileManager defaultManager];
tempDir = [pathString stringByAppendingString:#"/icon.iconset"];
NSURL *newDir = [NSURL fileURLWithPath:tempDir];
[filemgr createDirectoryAtURL: newDir withIntermediateDirectories:YES attributes: nil error:nil];
DropZone *myZone = [[DropZone alloc] init];
[myZone scaleIcons:tempDir];
NSAlert *alert = [[NSAlert alloc] init];
[alert setMessageText:#"Done!"];
[alert runModal];
}
the image get's pulled from the pastebaord:
- (BOOL)performDragOperation:(id<NSDraggingInfo>)sender{
if ([NSImage canInitWithPasteboard:[sender draggingPasteboard]]) {
image = [[NSImage alloc]initWithPasteboard:[sender draggingPasteboard]];
[self setImage:image];
[self setImageAlignment: NSImageAlignCenter];
}
return YES;
}
For some reason my "image" gets lost. Could somebody help?
The problem is that you're creating a new instance of DropZone in your app delegate, but I'm assuming that you created the image view in IB and changed its class to DropZone. Is that correct? If so, you need to have an IBOutlet in the app delegate connected to the image view in IB, and have this:
[self.iv scaleIcons:tempDir];
where iv is my IBOutlet.
Without knowing where "image" comes from, I would say your problem is in these lines...
anImage = [[NSImage alloc]init];
anImage = image;
You should just grab the image from the imageView...
anImage = [myImageView image];
So, the code to copy part of my screen to the pasteboard works because it was successfully coping it to my photo album. But, I want to be able to paste the partial screenshot into a new SMS message. I know it will have to be done manually (long hold on message and Paste), but it either pasted nothing, or does not have the Paste option (as it's saving it as a String). The middle portion of the code is the part I'm struggling with. Any help would be great. I've changed the forPasteboardType to "image" but that does not work either.
//Capture part of Screen Shot
UIGraphicsBeginImageContext(self.view.bounds.size);
CGContextRef c = UIGraphicsGetCurrentContext();
CGContextTranslateCTM(c, 0, 98); //

UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
//Send Screenshot to Pasteboard
UIPasteboard *pasteBoard = [UIPasteboard pasteboardWithName:UIPasteboardNameGeneral create:YES];
pasteBoard.persistent = YES;
NSData *data = UIImagePNGRepresentation(viewImage);
[pasteBoard setData:data forPasteboardType:(NSString *)kUTTypePNG];

NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
UIImage *img = [[UIImage alloc] initWithContentsOfFile:#"contactHeader.png"];
_headersView = [[UIImageView alloc] initWithImage:img];
I have already hooked up the connections for the UIImageView (_headersView) in IB. The image I want to load is in my project tree structure as well.
Am I creating the UIImage the right way?
If the file is in your bundle you can just use
UIImage *img = [UIImage imageNamed:#"contactHeader"];
_headersView = [[UIImageView alloc] initWithImage:img];
If the image is in your documents directory you can use
// Get the path to your documents directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
// Add the file to the end of the documents path
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"contactHeader.png"];
UIImage *img = [[UIImage alloc] imageWithContentsOfFile:filePath];
_headersView = [[UIImageView alloc] initWithImage:img];
[img release]; img = nil;
try this
-(NSString *)getPath:(NSString *)filename
{
self.path = [[NSBundle mainBundle]pathForResource:filename ofType:#"png"];
return path;
path = nil;
}
self.youImageView.image = [UIImage imageWithContentsOfFile:[self getPath:#"123"]];
