I tried to add a AccessoryView to a NSSavePanel but sometimes the AccessoryView (it's elements) is disables and sometimes not. Hopefully anyone has a idea.
Here is my code:
NSWindow *window = [[NSApp delegate] window];
// Get savePath
NSSavePanel *spanel = [NSSavePanel savePanel];
__block SaveAccessoryViewController *saveAccessoryViewController = [[SaveAccessoryViewController alloc] initWithNibName:#"SaveAccessoryView" bundle:nil];
[spanel setAllowedFileTypes:[NSArray arrayWithObject:#"pdf"]];
[spanel setAccessoryView:saveAccessoryViewController.view];
[spanel beginSheetModalForWindow:window completionHandler:^(NSInteger returnCode) {
...
I had the same problem and I concluded that it had to do with ARC (Automatic Reference Count) settings for the project.
If you are using ARC make sure the settings are correct both on project and target.
In my case I had enabled ARC on target but not on project, after enabling ARC on project (and dealing with resulting errors and warnings) everything works perfectly now.

I am trying to configure the photoeditorSDK for iOS, but am struggling.
My current issues are the following:
1. When a user clicks on the brush toolMenuItem, it does not do anything. Other toolMenuItems do what they are supposed to (e.g. Size).
Similarly, when a user adds text through the Text Menu Item, it works, however when they try to resize the text - they can't click it.
I believe these issues are related - that is why I opted them together.
Here's the code snippet used to configure the control:
NSError *dataCreationError;
NSURL *aLocalURL = [NSURL URLWithString:filepath];
NSData *imageData = [NSData dataWithContentsOfFile:aLocalURL.path options:0 error:&dataCreationError];
if (imageData && !dataCreationError) {
PESDKConfiguration *configuration = [[PESDKConfiguration alloc] initWithBuilder:^(PESDKConfigurationBuilder * _Nonnull builder) {
// See Configuration section
}];
NSMutableArray<PESDKPhotoEditMenuItem *> *menuItems = [[PESDKPhotoEditMenuItem defaultItems] mutableCopy];
[menuItems removeLastObject]; // Remove last menu item ('Magic')
PESDKPhotoEditViewController *photoEditViewController = [[PESDKPhotoEditViewController alloc] initWithData:imageData configuration:configuration];
photoEditViewController.delegate = self;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:photoEditViewController];
dispatch_async(dispatch_get_main_queue(), ^{
[self.viewController presentViewController:navigationController animated:YES completion:nil];
});
} else if (dataCreationError) {
NSLog(#"Failed to open given path: %#", dataCreationError);
}
This is a bug on our side and will be fixed with the next release, which will go live this week. As a workaround, we updated your subscription. You just need to generate a new license file using our dashboard and replace the existing one in your app. This should fix both issues, but will add the Sticker tool to your menu items. You may remove it just like you did with the Magic tool.
If you have further questions, just let me know!
Does Gluon Mobile have any guidance on implementing a share button? My goal is to be able to share a string containing a link to different apps on the phone. At the moment, I need this only for the iOS implementation. I was able to find this link that provides a simple way to do this in Objective-C:
- (IBAction)shareButton:(UIBarButtonItem *)sender
{
NSString *textToShare = #"Look at this awesome website for aspiring iOS Developers!";
NSURL *myWebsite = [NSURL URLWithString:#"http://www.codingexplorer.com/"];
NSArray *objectsToShare = #[textToShare, myWebsite];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
NSArray *excludeActivities = #[UIActivityTypeAirDrop,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo];
activityVC.excludedActivityTypes = excludeActivities;
[self presentViewController:activityVC animated:YES completion:nil];
}
Looking at the GoNative application example on the Gluon website, it seems like I can use the above code snippet where needed as the native iOS code. Do I have to update the ios build gradle to account for the UIActivity class mentioned in the first link above?
Update*
I have been able to get this to work based on help in this question here.
However when trying to install the native library, I get this error which is understandable as self is unknown in the scope of the code. How would I be able to do this? Instantiate a popover or dialog and pass the activityVC to it?
/Users/ashishsharma/NetBeansProjects/konfamdbranch/src/ios/native/Share.m:25:6: error: use of undeclared identifier 'self' [self presentViewController:activityVC animated:YES completion:nil];
So I was able to solve this using examples on the internet (shown above) along with going through the existing code for the Barcode Scan Service. The issue I was experiencing with the above code was that the present view controller could not be found. However, looking at the bit bucket source for Barcode Scan, I was able to get the root view with the following code:
if(![[UIApplication sharedApplication] keyWindow])
{
NSLog(#"key window was nil");
return;
}
// get the root view controller
UIViewController *rootViewController = [[[UIApplication sharedApplication] keyWindow] rootViewController];
if(!rootViewController)
{
NSLog(#"rootViewController was nil");
return;
}
Then in the code snippet I placed in the question, replace self with rootViewController:
[rootViewController presentViewController:activityVC animated:YES completion:nil];
This leads to the modified code snippet:
#import <UIKit/UIKit.h>
#include "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/jni.h"
JNIEXPORT void JNICALL Java_com_gluonhq_charm_down_plugins_ios_IOSShareService_shareMessage
(JNIEnv *env, jclass jClass, jstring jMessage) {
if(![[UIApplication sharedApplication] keyWindow])
{
NSLog(#"key window was nil");
return;
}
// get the root view controller
UIViewController *rootViewController = [[[UIApplication sharedApplication] keyWindow] rootViewController];
if(!rootViewController)
{
NSLog(#"rootViewController was nil");
return;
}
NSString *textToShare = #"Check out this site!";
NSURL *myWebsite = [NSURL URLWithString:#"http://www.google.com/"];
NSArray *objectsToShare = #[textToShare, myWebsite];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
NSArray *excludeActivities = #[UIActivityTypeAirDrop,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo];
activityVC.excludedActivityTypes = excludeActivities;
[rootViewController presentViewController:activityVC animated:YES completion:nil];
}
Note I followed the GoNative application to generate my objective-c/ios files correctly.
This leads to a minimal functionality share implementation only because I don't have Facebook installed on the IPhone simulator.
In my app, the rotation works fine in iOS7 but not working in iOS8.
As you can see, the status bar rotates, but the view controller does not.
I found the issue is caused by main storyboard setting, but I have no idea why it cased the issue. I just removed main storyboard setting in project file and everything works fine in iOS8.
Following is my codes to load storyboard.
[self setMainStoryboard:[UIStoryboard storyboardWithName:#"MainStoryboard-ipad" bundle:nil]];
UIViewController *vc = [mainStoryboard instantiateInitialViewController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
[self.window setRootViewController:vc];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
Maybe I used the wrong way to load storyboard?
I fix the problem, but I think this might not be a good solution. It's just a workaround. Anyway, here is what I have done. If you run into the same problem, you can try removing main storyboard setting in your target.
That's it, no further steps. Everything is fine after I remove main storyboard setting. Maybe the way I load main storyboard is incorrect or there is something wrong with my setting of storyboard.
Following is the codes I used to load storyboard:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Storyboard" bundle:nil];
UIViewController *vc = [storyboard instantiateInitialViewController];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
// Override point for customization after application launch.
[self.window setRootViewController:nav];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
If anyone know the correct way to use main storyboard, please give me some feedback. Thanks!
I have a small png that I am adding to a view which I am pretty sure I had working previously but suddenly stopped working on the iPad itself while continuing to work fine on the iPad simulator.
Here is the code I am using to add the image to the view...
UIImageView *bottomResizer = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"resizeLine.png"]];
bottomResizer.center = CGPointMake(bottomResizer.center.x, bottomResizer.center.y+self.frame.size.height-12);
bottomResizer.tag = 301;
[self addSubview:bottomResizer];
[bottomResizer release];
This occurs in a UIGestureRecognizerStateBegan event. The following code in removes the image in a touchesEnded event without any errors even though you cannot see it.
NSArray *subViews = [self subviews];
int count = [subViews count];
for (int i =count-1; i>=0; i--) {
if([[subViews objectAtIndex:i] tag] == 301) {
[[subViews objectAtIndex:i] removeFromSuperview];
}
}
I don't think it is anything I changed in my code since it works in the simulator. Not sure where to look next for the problem. I have reset the simulator to see if it would break after a reset. I have also cleaned the project.
Thanks.

Put a breakpoint AFTER this line UIImageView *bottomResizer = [[UIImageView alloc]...
Then on the console "po [bottomResizer image]"
If it is nil then either the resource is not getting copied correctly into the bundle OR you could have a corrupt image that the device cannot load.
I'd like to adjust the NSApplicationIcon image that gets shown automatically in all alerts to be something different than what is in the app bundle.
I know that it's possible to set the dock icon with [NSApplication setApplicationIconImage:] -- but this only affects the dock, and nothing else.
I'm able to work around this issue some of the time: I have an NSAlert *, I can call setIcon: to display my alternate image.
Unfortunately, I have a lot of nibs that have NSImageView's with NSApplicationIcon, that I would like to affect, and it would be a hassle to create outlets and put in code to change the icon. And for any alerts that I'm bringing up with the BeginAlert... type calls (which don't give an NSAlert object to muck with), I'm completely out of luck.
Can anybody think of a reasonable way to globally (for the life of a running application) override the NSApplicationIcon that is used by AppKit, with my own image, so that I can get 100% of the alerts replaced (and make my code simpler)?
Swizzle the [NSImage imageNamed:] method? This method works at least on Snow Leopard, YMMV.
In an NSImage category:
#implementation NSImage (Magic)
+ (void)load {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
// have to call imageNamed: once prior to swizzling to avoid infinite loop
[[NSApplication sharedApplication] applicationIconImage];
// swizzle!
NSError *error = nil;
if (![NSImage jr_swizzleClassMethod:#selector(imageNamed:) withClassMethod:#selector(_sensible_imageNamed:) error:&error])
NSLog(#"couldn't swizzle imageNamed: application icons will not update: %#", error);
[pool release];
}
+ (id)_sensible_imageNamed:(NSString *)name {
if ([name isEqualToString:#"NSApplicationIcon"])
return [[NSApplication sharedApplication] applicationIconImage];
return [self _sensible_imageNamed:name];
}
#end
With this hacked up (untested, just wrote it) jr_swizzleClassMethod:... implementation:
+ (BOOL)jr_swizzleClassMethod:(SEL)origSel_ withClassMethod:(SEL)altSel_ error:(NSError**)error_ {
#if OBJC_API_VERSION >= 2
Method origMethod = class_getClassMethod(self, origSel_);
if (!origMethod) {
SetNSError(error_, #"original method %# not found for class %#", NSStringFromSelector(origSel_), [self className]);
return NO;
}
Method altMethod = class_getClassMethod(self, altSel_);
if (!altMethod) {
SetNSError(error_, #"alternate method %# not found for class %#", NSStringFromSelector(altSel_), [self className]);
return NO;
}
id metaClass = objc_getMetaClass(class_getName(self));
class_addMethod(metaClass,
origSel_,
class_getMethodImplementation(metaClass, origSel_),
method_getTypeEncoding(origMethod));
class_addMethod(metaClass,
altSel_,
class_getMethodImplementation(metaClass, altSel_),
method_getTypeEncoding(altMethod));
method_exchangeImplementations(class_getClassMethod(self, origSel_), class_getClassMethod(self, altSel_));
return YES;
#else
assert(0);
return NO;
#endif
}
Then, this method to illustrate the point:
- (void)doMagic:(id)sender {
static int i = 0;
i = (i+1) % 2;
if (i)
[[NSApplication sharedApplication] setApplicationIconImage:[NSImage imageNamed:NSImageNameBonjour]];
else
[[NSApplication sharedApplication] setApplicationIconImage:[NSImage imageNamed:NSImageNameDotMac]];
// any pre-populated image views have to be set to nil first, otherwise their icon won't change
// [imageView setImage:nil];
// [imageView setImage:[NSImage imageNamed:NSImageNameApplicationIcon]];
NSAlert *alert = [[[NSAlert alloc] init] autorelease];
[alert setMessageText:#"Shazam!"];
[alert runModal];
}
A couple of caveats:
Any image view already created must have setImage: called twice, as seen above to register the image changing. Don't know why.
There may be a better way to force the initial imageNamed: call with #"NSApplicationIcon" than how I've done it.
Try [myImage setName:#"NSApplicationIcon"] (after setting it as the application icon image in NSApp).
Note: On 10.6 and later, you can and should use NSImageNameApplicationIcon instead of the string literal #"NSApplicationIcon".
