In my Monotouch application having the UIImageview to display the dicom images also one Reset Button.
I use various UIGestureRecognizer on it while applying the Pinch or Rotate or any 1 of these UIGestureRecognizer it perform the operation very well. But while click on the Reset Button image get reset and application at the same instance get is closed.
I don't want to close the application while click on Reset Button
my code is
override void ViewDidLoad()
{
this.BtnReset.TouchDown += ResetHandler;
}
void ResetHandler (object sender, EventArgs e)
{
ImgView.Transform = CGAffineTransform.MakeIdentity ();
}
To debug this:
Does this occur on simulator, on phone or both?
Does the Application Output tell you anything about what's going wrong - e.g. a crash trace?
Can you see the debug output - e.g. on the console in xcode.
Can you put a breakpoint in the ResetHandler method - can you debug it?
It's hard to see any issue with the code as is - perhaps this might be as simple as the variable being null or perhaps you are hitting some jit/aot compiler or linker error.

I'm creating snapshots using Fastlane. As my application uses "Push Notifications", when the app is launched it always displays to the user the pop up that requests the authorization to send this kind of messages. There is a method that is called in the AppDelegate UIApplication.shared.registerForRemoteNotifications(), this method is the one that "shows" the pop up to the user.
I have tried something like:
#if !DEBUG
UIApplication.shared.registerForRemoteNotifications()
#endif
#if TARGET_IPHONE_SIMULATOR
UIApplication.shared.registerForRemoteNotifications()
#endif
I also tried to set a Global variable but it hasn't been possible to find a place where to set this variable, because it never works
I always get the same behavior.
I would expect that the first time I run the test in the simulator, it does not display the message.
Thanks.
I found an easy way to avoid this screenshot.
Before the screenshot is taken, I simply press the button "Allow"
let systemAlerts = XCUIApplication(bundleIdentifier: "com.apple.springboard").alerts
if systemAlerts.buttons["Allow"].exists {
systemAlerts.buttons["Allow"].tap()
}
Simple an easy :)
I'm new at Swift 3 and I try to make a print("Test") in a Widget extension.
I tried the same code in ViewController.swift and It works ok. I don't know why it works there but it doesn't on TodayViewController.swift. I can't access to objects too.
func loadData() {
let query = PFQuery(className: "Noticias")
query.whereKey("titulo", equalTo:"Es Navidad")
query.findObjectsInBackground(block: { (objects : [PFObject]?, error: Error?) -> Void in
if error == nil {
// The find succeeded.
print("Successfully retrieved \(objects!.count) scores.")
// Do something with the found objects
if let objects = objects {
for object in objects {
print(object.objectId!)
}
}
} else {
// Log details of the failure
print("bad day homie")
print(error!)
}
})
}
I attach I picture to see it clearly. If I try to print on the file marked as Work, it works. But if I try it on the file marked ad NO, it doesn't.
It is extremely difficult to retrieve print messages from an extension. The problem is that it's an extension! It isn't running in your app, so it doesn't arrive at your console. Sometimes I find you can solve this problem by switching the debugged process in the Debug Bar at the top of the debug area (at the bottom of the screen, not shown in your screen shot), but at other times this doesn't work.
I'll illustrate a possible technique that seems to be pretty reliable. Look at this screen shot:
"Expand" is an action extension. But my containing app is called "bk2ch13...". So how will I ever manage to pause at the breakpoint shown at the right, which is in the action extension? This is what I do.
First, with the screen as shown above, I build and run my containing app.
Then, I switch the target to the action extension:
Now I build and run again. But now I am trying to run an action extension, which you can't do, so Xcode asks me what app to run:
So I choose "bk2ch13...". So now we are running my host app again, but we are debugging the extension. So I use my host app to exercise the extension, and sure enough, we pause at the breakpoints and print statements arrive into the console.
Note, in that screen shot, how the debug bar clearly shows that we are talking to the extension, not the host app.
Is there any way of testing the UIApplication shortcuts within XCUITests?
I know that in order to test 3d shortcuts in a simulator you need a trackpad with force touch, but I was wondering if I could write tests that test my shortcuts.
Looks like yes! You'll need to expose a private API, though. Exported XCUIElement header from Facebook's WebDriverAgent here.
Or, if that's the only thing you need, just expose it ala:
#interface XCUIElement (Private)
- (void)forcePress;
#end
And then to force press your icon by going to the springboard and getting your icon element see my answer here.
class Springboard {
// this is another private method you'll need to expose (see linked other answer)
static let springboard = XCUIApplication(privateWithPath: nil, bundleID: "com.apple.springboard")
/// Open the 3d touch menu
class func open3dTouchMenu() {
XCUIApplication().terminate() // this may or may not be necessary depending on your desired function / app state
// Resolve the query for the springboard rather than launching it
springboard.resolve()
// Force delete the app from the springboard
let icon = springboard.icons["MyAppName"]
if icon.exists {
icon.forcePress()
// do something with the menu that comes up
}
}
}
* I have not tested this yet.
I need to test some behaviors of the iOS 8 at the very first start of my app. Is it possible to simulate this in Xcode 6? If yes, then how?
Deleting the app will do it but note that certain pieces of information will be cached for a while like your permissions settings (notification, calendar, etc.). You can go to settings.app and reset settings to clear those out if that matters in your use case.
If you mean the FIRST start of the app, then what I did to achive this is, on start (viewDidLoad) check in the NSUserDefaults for example ,if the value "hasAlreadyStarted" exists (NSUserDefaults.objectForKey(..) ), if not, then its the first start of the app, and then i would set the value to true, so when you close the app, and open again, the value will exist.
Dareon I'm not sure what exactly you want to achieve. In Xcode 6 yes you can simulate your app from start. If you want to test behaviours I think you are looking for instruments. Right Click on the Xcode icon in your dock select option and choose instruments. You can add several instruments your phone or emulator support like connectivity or gps or memory to see exactly the behaviour of your app. Hope that helps
Well if by very start of the app cycle you mean before the app loads, there is a way.
In your ViewController call the ViewWillLoad function:
class ViewController
{
override func viewWillAppear(animated: Bool)
{
// your code
}
}
This event will be called before the view loads or appears.
Hope it helps :)
As Shanti K said in the comment, if you delete your application from the simulator and then run it again, you will be simulating the first run. To delete the application from the simulator, you mimic the same behavior on a device.
Click and hold on the icon, until they start shaking. Click the close X next to your application, and verify that you want to delete it if it asks. Then Shift + Command + H to simulate hitting the home button.
I'm having a strange problem while debugging my Blackberry Application on a real device (BB Bold 9700). When I debug the same application within the BB emulator, the app runs fine, but when I run it on the real device, the app behaves differently (custom painting goes completely wrong). What's even worse is that my Eclipse environment seems to be unable to view live objects correctly while being at a break point (debug time).
I've added a screenshot to illustrate the strange behaviour:
As you can see, the app stops at the breakpoint within the IF statement, but the Variables pane says that the variable "methodName" equals null. Moreover, when I want to look at the variable "methodArguments" which is of type org.json.me.JSONArray, it says "details unavailable - not supported by VM".
Does anyone know what's going on here? My app works great on the emulator, but it's currently useless on the real device.
Thanks in advance!
I think I fixed it:
The problem was that I was laying out Fields on a manager that wasn't yet added to the viewstack.
What did the trick for me was overriding onDisplay() in the manager that contained the Fields that were displayed wrong:
protected void onDisplay()
{
//Make sure superclass is called
super.onDisplay();
/*You have to call "this.setDirty(true)" when you perform layout on a
*manager that isn't added to the viewstack. Then you can use
*"this.isDirty()" to determine whether you need to re-layout the fields
*when the manager becomes visible.*/
if(this.isDirty())
{
//I'm not sure if I need to use "invokeAndWait" and not "invokeLater"
UiApplication.getUiApplication().invokeAndWait(new Runnable()
{
public void run()
{
for (int i = 0; i < getFieldCount(); i++)
{
/*This (custom) function makes sure the Field gets its
*size and position*/
layoutItem(getField(i));
}
}
});
//Make sure you set "dirty" to false, to make sure this only happens once
this.setDirty(false);
}
}
If anyone has a better solution, I'd be glad to hear it (and maybe improve my app).
org.json.me.JSONArray, it says "details unavailable - not supported by VM".
the JSON related stuff is not available on device running 4.5 and 4.6 BB OS. Import it into the code.
Download it from here.
https://github.com/douglascrockford/JSON-java
it is available as Open Source and then use it into your applications.
