display directory contents in uitableview - ios4

i need some help.I have directory which contains multiple files.
I have path for that directory,
i want to display the contents of directory in a uitableview.
Like in each cell a file of that directory.
when tapping that cell i want to open that file in iPhone.
Please help me.
Thanks in advance!!

Refer to this article for folder listing
then once you've grabbed all the information, use the UITableViewController to display the information in the cells. Then handle each file type depending on what it is (images? videos?) by overriding
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
You can find the documentation and some apple examples here

__layout.reset has been removed in favour of named layouts

I have a page set up in this format
original reset image›
I looked at forums and it said i should change the inner layout page to __layout#reset.svelte. However when i do that, I get another error.
reset image using #reset instead of .reset
Does anyone know how i can put in a reset __layout inside of a folder and get it to override the parent layout?
Your error is because __layout#reset.svelte would be looking for a __layout-reset.svelte file in it's current directory, or any parent directory directory, to be a sub-layout for. You don't have a __layout-reset.svelte file.
As Thomas Hennes mentioned in the other thread. If you wanted to have it act like the reset, you'd need to create a __layout-reset.svelte file in the current folder or (more useful for the entire app, in the root folder) and have it be a blank <slot />. From there, you can do __layout#reset.svelte to which will allow you to make a completely new layout.
I think that you can solve this problem by fallowing this steps :
Create "__layout-choseNameYouWant.svelte" at the same level as "__layout.svelte"
Create "guides#theSameNameYouGaveForLayoutFile.svelte" at the same level as
about.svelte
Layouts can themselves choose to inherit from named layouts
create "__layout-root.svelte" at the same level as index.svelte and about.svelte with the following code
<slot/>
create "__layout#root.svelte" in guides folder with the following
<slot></slot>

How can I specifiy an alternate layout for NotFound.cshml and ErrorPage.cshtml in Orchard CMS

I know you can use layout filters for normal pages with urls, but upon errors the view changes while keeping the url the same, so I can't utilize a new layout based on the path. Any help would be appreciated. Thank you!
Off the top of my head:
If you look in Core > Shapes > Views, you will see two files - one called ErrorPage.cshtml and one called NotFound.cshtml. Simply copy these files and paste them into your theme's view folder.
I have not tested this method with these particular pages, but I did do something similar with the LogOn widget.
Something to bear in mind is that the contents of these files will be rendered in the Content zone of your current theme.

Trying to install custom font in xcode 4.2, iOS 5.0, but receiving error "Validation failed: [duplicate]

I want to use font "MgOpen Modata" in my iphone App. But I dont see it in the font list in Property inspector.
How do I include that font so that I can use it?
Add the font files to your resource files
Edit your Info.plist: Add a new entry with the key Fonts provided by application.
For each of your files, add the file name to this array
On the example below, I've added the font "DejaVu Sans Mono":
In your application you can the use [UIFont fontWithName:#"DejaVuSansMono-Bold" size:14.f].
Or if you want to use it in html/css, just use font-family:DejaVu Sans Mono;
Note: this is available in iOS 3.2 and later.
I found this walkthrough was the best
Although the above accepted answer does work I found that if you added text into an XIB file and then set the font to our new font then the text didn't update.
Making sure the new font is included in resources fixed this problem (taken directly from walkthrough):
"This should not be a problem but sometimes when you’re having trouble getting your font face to show up, this can be a source of headache so let’s double check now to rule it out as a potential pitfall.
Go to your project Build Phases pane by highlighting the XCode project file in your solution explorer and on the right hand side, select “Build Phases”. You’ll see that one of the sections you can expand is “Copy Bundle Resources”. Open that list and make sure that your fonts are included in that list."
The other stuff in the walkthrough is the same kind of stuff (add the file to your project and to the plist file too)
All credit to Code with Chris for this answer which saved me a lot of time and effort and I am merely copying a shot from his page to allow this answer to stand on its own feet instead of requiring you to click the link.
I think is better for a dev to have the plist structure as raw source code. I'm leaving it for copy/paste:
<key>UIAppFonts</key>
<array>
<string>Roboto-BoldItalic.ttf</string>
<string>Roboto-Medium.ttf</string>
<string>Roboto-MediumItalic.ttf</string>
<string>Roboto-Regular.ttf</string>
<string>Roboto-Bold.ttf</string>
</array>
Copy this snippet and modify the strings keys into the array to your desired fonts. Hint: To view the plist as raw source code please click secondary button over the file and select Open As -> Source code.
EDIT
// Logs fonts ordered by name
for (NSString* family in [[UIFont familyNames] sortedArrayUsingSelector:#selector(compare:)])
{
NSLog(#"%#", family);
for (NSString* name in [[UIFont fontNamesForFamilyName:family] sortedArrayUsingSelector:#selector(compare:)])
{
NSLog(#" %#", name);
}
}
After adding the fonts could be useful to add to (for example) the AppDelegate.m class to see what are the real fonts names (on the bundle). A problem I encountered various times that I was loading the fonts with a wrong name assuming that the font filename as the correct one. Sometimes it differs from the bundle real name.
In addition to this you can check the file full name using the file info window (cmd+i) on finder (macOS).
Example to clarify:
File Name = "DroidSansEthiopic-Regular"
Processed Name in bundle = "Droid Sans Ethiopic"
Don't forget to add the fonts to the targets compile bundle resources by going to 'Targets' -> 'Build Phases' -> 'Copy Bundle Resources' and add all the fonts manually
Most of the time we forget to add font to the application Target. Make sure you did not forget this important step. Mind checking right panel File Inspector > Target Membership checkbox.
Also you can check wether font is added well to your application or not by running this code snippet in anywhere on your app.
for (NSString* family in [UIFont familyNames])
{
NSLog(#"%#", family);
for (NSString* name in [UIFont fontNamesForFamilyName: family])
{
NSLog(#" %#", name);
}
}
EDIT
ALPHABETIC ORDER:
for (NSString* family in [[UIFont familyNames] sortedArrayUsingSelector:#selector(compare:)])
{
NSLog(#"%#", family);
for (NSString* name in [[UIFont fontNamesForFamilyName:family] sortedArrayUsingSelector:#selector(compare:)])
{
NSLog(#" %#", name);
}
}
This will populate a list of available fonts in your app, where your added font will also appear.
Its Easy and simple now- Tested in Xcode 9.2 and swift 4
Steps to add font to your Xcode
Select your UILabel, UITextField or whatever then under fonts section and follow
Step 1
Select settings menu from left corner of font selection screen. And choose font manager option.
Step 2
Click on the add button as marked below.
Step 3
Select the folder that contains your font. It will be loaded into XCode fonts list.
Steps to add fonts to your project
Don't forget to add description to your plist with the key Fonts provided by application. and put font files inside copy bundle resources under project target settings.
Yes! thats it.. njoy..
You can use [UIFont fontWithName:#"ArialMT" size:14]; method directly, if you want to change your font style. Also all the fonts may not be available in iphone library.Just refer this for available font styles.
If you have .otf format. sometime this format doesnt work. Convert .otf format to .ttf. There are bunch of font converter online.
Once you add the custom font to your .plist file under Fonts provided by application as explained above. Make sure in your Project Target under Build Phase -> copy Bundel Resourse that file is present. If not then add it.
Then just in your code add this [UIFont fontWithName:#"your custom font" size:your choice of size];
In Xamarin iOS
Step 1:
First of all you have to add your .ttf or .otf file into your Project.
like Roboto-BoldItalic.ttf .
Step 2 :
Right click on the Font and select property
Build Action --> Content
Copy to output directory --> Always Copy
Step 3:
go to info.plist
select property Fonts provided by application and add the font name.
Step 4:
set Font programatically below way
account.Font = UIFont.FromName("Roboto-BoldItalic", 18f);

UITextView does not display my text

I have a list of images (jpg) that I am displaying in the detailView and each image has a corresponding text file with information about the image. I am trying to use a UITextView to display the contents of the text file, but I have trouble getting it to display anything at all. I have made my text view read-only as I do not want to contents of my .txt files to be editable.
This is what I have:
NSString *file = [[NSBundle mainBundle] pathForResource:#"%#" ofType:#"txt"];
if (file){
NSString *textFromFile = [NSString stringWithContentsofFile:file];
textView.text = textFromFile;
}
I think that you probably want to use a label to display small snippets of non-interactive text. Afterwards make sure that you link the UI component you decide on with the File Owner in order to actually connect your variable declaration in the code to the UI component. Let me know how this goes!

UIKit is not open source; the source code is not available.
As Jim said, the source code ad an UIKit element is not available because it isn't open source.
But if you are searching for source code that show how to use them, you can search on the Developer Site.
UICatalog source code is what are you looking for.
It shows how to use the most common UIKit's element, like buttons, pickers, alerts and other...
