I am trying to detect gestures on a specific part of my screen close to the right hand most side.
When I try tapping using this approach (iOS simulator: how to do a 2 finger single tap on a mac laptop?), the two "fingers" appear at opposite ends of the screen. How do I get the simulator to tap so that the "fingers" are next to each other.
Use Option key to show two fingers icons on simulator screen. Place them as close as you want them to be. Then press Shift to move them to wherever on the screen you want.
When in the simulator, hold the option key down and click - this will simulate a two-finger tap!

On android one can add listener to Backhandler to detect hardware back action. So, if i create a screen and modify the content of the screen upon some action, then it is easy to go back to previous content with backhandler listener.
On ios, this is not possible to do with the swipe gesture.
React navigation does provide swipe gesture enable/disable to disable the action all together. But if i want to use the swipe gesture to update the content of the app, is it possible with react native/react navigation?
Or adding new screens with different content is the only and recommended option?
for example signing up on the app.
On android what i do is create a single screen and modify its content with different sub components when user presses the next button and its easier to go back by listening to hardware press back. But on ios one can go back by swiping left to right. But using react navigation it goes back to previous screen and i find no way to listen to the gesture and go back to previous sub component instead of previous screen.
React Native Swipe Gestures use this library.
I hope it help you.
I'm working on an app which has buttons at the bottom of the screen(looks like tab bar). I found that if I enable the access to control center in app, there will be a notable delay between tapping on the buttons and the highlighted image showing. In fact the highlighted image will never show if I do not hold on the touch for at least about 0.5 second. I'm wondering if there is a way to disable the delay even the access of control center in app is ON so that users of my app will know the buttons did have been tapped. Any hint will be appreciated.
I have a scroll page that I specified two fingers minimum. It works on my device, but don't know how to mimic this gesture on Simulator. I can mimic one-finger scroll without problem. I've tried option/ctrl/shift etc, but couldn't get it work. Maybe my combination is wrong. Anyone knows how? Thanks.
Holding the "Alt/Option" key and dragging simulates multi-touch pinch-to-zoom.
Holding "Alt/Option + Shift" and dragging simulates multi-touch scrolling.
There is a nice table with all the supported gestures in the iOS Simulator User Guide from Apple. Here is the extract for the two-finger drag:
Place the pointer where you want the two-finger drag to occur.
Hold down the Option key.
Move the circles that represent finger touches to the start position.
Move the center of the pinch target by holding down the Shift key, moving the circles to the desired center position, and releasing the Shift key.
Hold down the Shift key and the mouse button, move the circles in the direction you want to drag, and release both the Shift key and the mouse button.
Hope it helps.
To appear two fingers:
press ALT and drag mouse.
To zoom using two fingers:
press ALT and press SHIFT (to adjust touches.After adjusting release SHIFT key) and drag mouse.
Things moved around in Sierra for me, but here is how I enabled 3-finger scrolling:
**System Preferences > Accessibility
Scroll down to Mouse & Trackpad and tap Trackpad options
Make sure 'Enable Dragging' is selected
Select 'three finger drag' from the drop-down
Makes such a big difference when testing on various devices & simulators.
The best way to scroll in the iPad simulator is by the Three Fingers dragging, which is a global setup of the OS X and not a particular feature of the iOS simulator.
In order to scroll using three fingers you need to turn on the 'Three Finger Drag' under TrackPad > Point and Click in the Settings App of OS X.
and to set the Mission Control and App Exposé to use four fingers (in TrackPad > More Gestures in the Settings App of OS X)
(I made beautiful screenshots, but I'm too rocky to post answers with images)
It works with Three finger scroll on the Track pad.
It works for me on MBP trackpad as well as on Magic Trackpad.
The clue is to enable "Three finger drag" in Trackpad settings (Preferences.app), then dragging, while ALT+SHIFT are pressed, makes scrolling work as expected.
It also works with the "Three finger scroll".
It kind of annoys me how small the iPad simulator is... Some apps I have in mind I have difficulty testing because of the small size of the iPad simulator. Is there anyway to make it larger than it currently is?
Menu Bar: Window->scale as shown in comments by chpwn.
You can always zoom the screen in. Usually something like control-scroll but check your mouse or trackpad system preferences. command-option-backslash toggles antialiasing if you need to see magnified pixels when zoomed in.
in iPhone Simulater menu bar go to
window > scale > 100%
To add to this, you can create a keyboard shortcut to make it easier:
goto System Preferences -> Keyboard -> Keyboard shortcuts
click small "+" at bottom of list
drop down Application list and scroll to bottom, choose Other
browse to /Developer/Platforms/iPhoneSimulator.platform/Developer/Applications (at least on my machine)
choose iOS Simulator
for Menu Title enter "100%" without the quotes
for Keyboard Shortcut, press your shortcut key e.g. Cmd-F ('F'ull screen)
click Add and you're done
close and restart the simulator and press Cmd-F
HTH - DF
press command 1, Command 2, or, Command 3. it will change the screen size. Easy fix!
I have a cordova app. I have written some custom code in file for swipe actions using touch events, mouse events which will identify the touchmove and swipe. I have a hamburger menu at the top left corner of my app. On clicking this will open a side panel with some animation. on opening the app in latest ios 13, first time click anywhere on the screen is having MouseEvent with x,y,screenX,screenY,pathX,pathY values as 0. this triggers the hamburger menu which is at the top left corner of app and opens the side panel.
Why is the first time click event on screen returns x,y values as 0?
This issue doesn't occur in Android device or iOS <= 12.0 version. Only observed in iOS 13.
On removing my code specific to touch, swipe events. Then this issue is not replicable.
I have another observation. As ios13 supports the pointer events, I have just tried to add code related to pointerEvent
document.addEventListener('pointerdown', function() {
console.log('pointerdown event');
})
This worked for me without removing any code related swipe.
Why there is such difference in the behaviour with the code.
Thanks in advance.
Thank you for your description, we also effected by this issue. Sometimes we experience "ghost" clicks on previous clicked place in our cordova app.
Only happens with iOS13, with both UIWebView and WKWebView.
Seems pointerdown eventlistener is a workaround for this.
