The webpage title on MobileSafari looks carven，host to make this effect?And what's the font family and font size of the title?
Thank you very much!
Open any iOS project in Xcode.
Launch MobileSafari in the simulator and visit google.
In Xcode, choose Product > Attach to Process > MobileSafari.
Choose Product > Debug > Pause.
In the debug console, type po [[UIApp keyWindow] recursiveDescription].
Note that this only works on the simulator. On the device, you can only attach to apps that you have installed using Xcode.
Doing all that gives you a printout of Mobile Safari's view hierarchy. Searching through it, I find this UILabel:
| | | | | <UILabel: 0x1096e800; frame = (0 0; 308 16); text = 'Google'; clipsToBounds = YES; userInteractionEnabled = NO; layer = <CALayer: 0x1096e8c0>>
The address of the UILabel object will be different each time we do this.
Anyway, we can print that label's font like this:
(lldb) po [0x1096e800 font]
$2 = 0x0bb88110 <UICFFont: 0xbb88110> font-family: ".Helvetica NeueUI"; font-weight: bold; font-style: normal; font-size: 13px
We can print its text color:
(lldb) po [0x1096e800 textColor]
$13 = 0x1096eb50 UIDeviceRGBColorSpace 0.173 0.212 0.259 0.9
We can also print its shadow color:
(lldb) po [0x1096e800 shadowColor]
$4 = 0x1096eb70 UIDeviceWhiteColorSpace 1 0.43
Printing the shadow offset is harder, because it is a CGSize structure, not a built-in type. The debugger doesn't know about CGSize because MobileSafari doesn't include debug information. We have to give the debugger a definition. This hideous command works:
(lldb) expr -o -- typedef struct { float x; float y; } CGSize; (id)[NSValue valueWithCGSize:(CGSize)[(id)0x1096e800 shadowOffset]]
$11 = 0x08063e60 NSSize: {0, 1}
It's the system's default font, Helvetica-Neue. In UIKit, you'd get it with [UIFont systemFontOfSize:...] or [UIFont boldSystemFontOfSize:...]. The "carve" effect is a simple white drop shadow. It's achieved with the shadowColor and shadowOffset properties of UILabel.

I would like to use my own pdf() plot device in an .Rnw document converted to a PDF with knitr. After the PDF of a figure is generated
it should call pdfCrop.off() instead of dev.off() (or whatever knitr calls); this would
perfectly crop the resulting figures. How can this be done?
The following MWE works (but without cropping) if (*) is commented out (and the line before properly closed).
\documentclass{article}
\begin{document}
<<knitr_options, echo = FALSE, results = "hide", purl = FALSE>>=
## Custom graphics device (for cropping .pdf):
pdfCrop <- function(file, width, height, ...)
{
f <- file
grDevices::pdf(f, width = width, height = height, onefile = FALSE)
assign(".pdfCrop.file", f, envir = globalenv())
}
pdfCrop.off <- function() # used automagically
{
grDevices::dev.off() # closing the pdf device
f <- get(".pdfCrop.file", envir = globalenv())
system(paste("pdfcrop --pdftexcmd pdftex", f, f, "1>/dev/null 2>&1"),
intern = FALSE) # crop the file (relies on PATH)
}
## knitr options
knitr::opts_chunk$set(fig.path = "./fig_", background = "#FFFFFF",
dev = "pdfCrop", fig.ext = "pdf") # (*) => how to use pdfCrop.off() instead of dev.off()?
#
<<MWE>>=
<<fig-MWE, eval = FALSE, echo = FALSE>>=
plot(1:10, 10:1)
#
\setkeys{Gin}{width=\textwidth}
\begin{figure}[htbp]
\centering
\framebox{
<<figMWE, echo = FALSE, fig.width=6, fig.height=6>>=
<<fig-MWE>>
#
}
\caption{Just some text to show the actual textwidth in order to see that the
figure is not perfectly horizontally aligned due to some white space which can
be avoided by properly crop the figure with an adequate pdf crop device.}
\end{figure}
\end{document}
knitr already provides a crop device based on pdfcrop, so we can use that via a hook:
\documentclass{article}
\begin{document}
<<knitr_options, echo = FALSE, results = "hide", purl = FALSE>>=
## knitr options
library(knitr)
knit_hooks$set(crop = hook_pdfcrop)
knitr::opts_chunk$set(fig.path = "./fig_", # all figures are saved as fig_*
background = "#FFFFFF", # avoid color
crop = TRUE) # always crop
#
<<MWE>>=
<<fig-MWE, eval = FALSE, echo = FALSE>>=
plot(1:10, 10:1)
#
\setkeys{Gin}{width=\textwidth}
\begin{figure}[htbp]
\centering
<<figMWE, echo = FALSE, fig.width=6, fig.height=6>>=
<<fig-MWE>>
#
\caption{Just some text to show the actual textwidth in order to see that the
figure is not perfectly horizontally aligned due to some white space which can
be avoided by properly crop the figure with an adequate pdf crop device.}
\end{figure}
\end{document}
I would like to add the new Google phones to the Emulated Devices in Chrome's dev tools.
Does anyone know the correct custom device settings for the Pixel 3 and Pixel 3 XL?
You must enter the viewport size on the google dev center, not screen resolution. So the viewports for pixel 3 and pixel 3 xl are as below.
Pixel 3: 412 x 824 aspect ratio: 16:9 ~ Device pixel ratio: 1.7
Pixel 3 xl: 412 x 847 aspect ratio: 16:9 ~ Device pixel ratio: 1.7
you can use something like this to know you device details :
<!DOCTYPE html>
<html>
<body>
<button onclick="OutputDeviceInfo()">Click me</button>
<p id="width"></p>
<p id="height"></p>
<p id="ratio"></p>
<script>
function OutputDeviceInfo() {
let deviceWidth = window.screen.width;
let deviceHeight = window.screen.height;
let devicePixelAspectRation = window.devicePixelRatio;
document.getElementById("width").innerHTML = deviceWidth;
document.getElementById("height").innerHTML = deviceHeight;
document.getElementById("ratio").innerHTML = devicePixelAspectRation;
console.log('Width: ' + deviceWidth);
console.log('Height: ' + deviceHeight);
console.log('Pixel Ratio: ' + devicePixelAspectRation);
}
</script>
</body>
</html>
Press F12 on Chrome Browser >> Click on toggle device tool bar (on left side small mobile icon) >> click on drop-down option where you can see spme list of devices are there, you can see last option "Edit"- click on that Edit option>> click on "Add custom device" button enter the details for your targets device
I'm using Ionic 3 on iPhone 7 plus with iOS 11. When I run my App, and fill in some text/input fields (basic forms) the app freezes for a few seconds and becomes completely unresponsive (which isn't good, not to say the least). I noticed this error coming up in Xcode, maybe that's the problem. Has anyone else encountered similar errors?
API error: <_UIKBCompatInputView: 0x13fd1d7c0; frame = (0 0; 0 0);
layer = > returned 0 width, assuming
UIViewNoIntrinsicMetric
Remove deprecated items from the forRoot config in app.module.ts
IonicModule.forRoot(),
Eg. remove these:
{
scrollPadding: true,
scrollAssist: false
}
See https://ionicframework.com/docs/utilities/config for more info.
I'm writing a Framer.js function to simulate the 'splash' effect when you tap a button or a layer, as per Google Material Design.
It looks something like this
tapSplash = (tapX,tapY) ->
tapSplashLayer = new layer
backgroundColor: "#ffffff"
opacity: 0.2
width: 500, height: 1500
borderRadius: 1500
midX: tapX
midY: tapY
After this, I have some code to run the animation.
My question is, how do I get the tapX and tapY coordinates? It is not good enough to use the midpoint of the layer that has been clicked/tapped - I want the animation to originate from the exact point the user tapped on
Check out your own answer to the question.
I've since then forked it and made changes so that taps on a computer or taps on a mobile device are recognized separately.
https://github.com/carignanboy1/Material-Design-Interactions/tree/improved-touch
touchEvent = Events.touchEvent(event)
if Utils.isPhone() || Utils.isTablet()
tX = touchEvent.clientX - layer.x
tY = touchEvent.clientY - layer.y
else
tX = touchEvent.offsetX
tY = touchEvent.offsetY
I would like to set the font size and familyname to the titleLabel. //Helvetica Neue UltraLight
[titleLabel setFont:[UIFont fontWithName:#"Helvetica Neue UltraLight" size:25.0f]];
This is not working.
Kindly tell me what could be wrong?
Any help will be appreciated?
the correct fontName is #"HelveticaNeue-UltraLight".
use something like this to get a nicely formatted list of available font names:
NSMutableString *str = [NSMutableString stringWithCapacity:1000];
for (NSString *familyName in [UIFont familyNames]) {
[str appendFormat:#"%#\n", familyName];
for (NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) {
[str appendFormat:#" %#\n", fontName];
}
[str appendString:#"\n"];
}
NSLog(#"%#", str);
this is the current list for iOS5.1:

You use wrong font name, correct one will be:
[titleLabel setFont:[UIFont fontWithName:#"HelveticaNeue-UltraLight" size:25.0f]];
You can see the list of all available font names for a given font family using +fontNamesForFamilyName: method in UIFont, e.g.:
[UIFont fontNamesForFamilyName:#"Helvetica Neue"]
Edit: Also mind that some fonts may not be present on all versions of iOS as Apple gradually adds (and sometimes probably removes) fonts from standard OS set.
It appears that "HelveticaNeue-UltraLight" font present in OS starting 5.0 version. If you want to use it in older OS versions you'll need to embed it to you application - check for example this answer for details how to do that
Please see List of Fonts available in iOS
and use font names according this...
