In a grouped table view, setting `separatorStyle` doesn&#39;t do anything. If you want to hide it, just do the following:

    tableView.separatorColor = [UIColor clearColor];

Use this

&lt;pre&gt;&lt;code&gt;tableView.separatorStyle = UITableViewCellSeparatorStyleNone;&lt;/code&gt;&lt;/pre&gt;

To remove the border of a table view write this line:

    self.myTableView.separatorColor = [UIColor clearColor];

If you want to remove both the border of a table view but the border between cells too, you have to write both lines:

    self.myTableView.separatorColor = [UIColor clearColor];
    self.myTableView.separatorStyle = UITableViewCellSeparatorStyleNone;

  

This did the trick for me:
	
    [dayTableView setSeparatorColor:[UIColor whiteColor]]; //or your background color

swift 4 use

    myTableView.separatorStyle = UITableViewCellSeparatorStyle.none


How about setSeparatorColor to your cell&#39;s background color?

I&#39;ve **inherited** a web app that I&#39;ve just discovered stores over 300,000 usernames/passwords in plain text in a SQL Server database.  I realize that this is a Very Bad Thing™.

Knowing that I&#39;ll have to update the login and password update processes to encrypt/decrypt, and with the smallest impact on the rest of the system, what would you recommend as the best way to remove the plain text passwords from the database?

Any help is appreciated.

**Edit: Sorry if I was unclear, I meant to ask what would be your procedure to encrypt/hash the passwords, not specific encryption/hashing methods.**  

Should I just:

 1. Make a backup of the DB
 2. Update login/update password code
 3. After hours, go through all records in the users table hashing the password and replacing each one
 4. Test to ensure users can still login/update passwords

I guess my concern is more from the sheer number of users so I want to make sure I&#39;m doing this correctly.

I have an html form that a user will fill out and print.  Once printed, these forms will be faxed or mailed to a government agency, and need to look close enough like the original form published by said agency that a government bureaucrat doesn&#39;t spot that this is a reproduction.  The data entered in the form is not saved anywhere or even submitted back to a web server.  All that matters is that our users can easily find these forms on our intranet site and type into the form for printing with their normal keyboard.

On the screen I want to leave the radio button as-is, to enforce and communicate radio button usage (choose only one option).  However, when it prints out I need it to print with the square checkbox style rather than the round radio button style.  I know how to use a media selector to set styles for print only, so that&#39;s not the issue.  It&#39;s just that I don&#39;t know if I can style the radio button like I want at all.  

If I can&#39;t get this working I&#39;m gonna have to create a checkbox to shadow each radio button, use javascript to keep the checkboxes and radio buttons in sync, and css to show the one I care about in the proper medium.  Obviously if I can just style them it would save a lot of work.

Can you style an html radio button to look like a checkbox?

I&#39;m wondering where the callbacks are (or if there are anything) for animations in a CALayer. Specifically, for implied animations like altering the frame, position, etc. In a UIView, you could do something like this:

	[UIView beginAnimations:@&quot;SlideOut&quot; context:nil];
	[UIView setAnimationDuration:.3];
	[UIView setAnimationDelegate:self];
	[UIView setAnimationDidStopSelector:@selector(animateOut:finished:context:)];
	CGRect frame = self.frame;
	frame.origin.y = 480;
	self.frame = frame;
	[UIView commitAnimations];

Specifically, the `setAnimationDidStopSelector` is what I want for an animation in a CALayer. Is there anything like that?

TIA.

I was expecting to be able to sprinkle NSLog function calls throughout my code, and that Xcode/gcc would automatically strip those calls out when building my Release/Distribution builds.

Should I avoid using this? If so, what alternatives are most common between experienced Objective-C programmers?

Is it true that one should not use NSLog() on production code?

Somehow my iPhone Simulator is unable to play sounds.  First an app I&#39;m working on using `AudioServicesPlaySystemSound()` stopped working.. I spent a while debugging this but sound is still working on the iPhone when I run the app on the device.  I get the same results with other iPhone apps such as the sample Crash Landing app.

I can&#39;t find a sound setting anywhere in the simulator or Xcode preferences.  I&#39;ve tried resetting the simulator through &quot;Reset Content and Settings&quot; menu item to no avail.

I want to send an email from my iPhone application. I have heard that the iOS SDK doesn&#39;t have an email API. I don&#39;t want to use the following code because it will exit my application:

    NSString *url = [NSString stringWithString: @&quot;mailto:foo@example.com?cc=bar@example.com&amp;subject=Greetings%20from%20Cupertino!&amp;body=Wish%20you%20were%20here!&quot;];
    [[UIApplication sharedApplication] openURL: [NSURL URLWithString: url]];

Is it possible to set some image as title of Navigation bar?

I want to load some images into my application from the file system. There&#39;s 2 easy ways to do this:

    [UIImage imageNamed:fullFileName]

or:

    NSString *fileLocation = [[NSBundle mainBundle] pathForResource:fileName ofType:extension];
    NSData *imageData = [NSData dataWithContentsOfFile:fileLocation];
    	
    [UIImage imageWithData:imageData];

I prefer the first one because it&#39;s a lot less code, but I have seen some people saying that the image is cached and that this method uses more memory? Since I don&#39;t trust people on most other forums, I thought I&#39;d ask the question here, is there any practical difference, and if so which one is &#39;better&#39;?

I have tried profiling my app using the Object Allocation instrument, and I can&#39;t see any practical difference, though I have only tried in the simulator, and not on an iPhone itself.

Difference between [UIImage imageNamed...] and [UIImage imageWithData...]?

I&#39;m having trouble resizing a tableHeaderView. It simple doesn&#39;t work.
 
 
1) Create a UITableView and UIView (100 x 320 px);
 
2) Set the UIView as tableHeaderView of the UITableView;
 
3) Build and Go. Everything is ok.
 
Now, I want to resizing the tableHeaderView, so I add this code in viewDidLoad:
 
 

    self.tableView.autoresizesSubviews = YES;
    
    self.tableView.tableHeaderView = myHeaderView;
    self.tableView.tableFooterView = myFooterView;
    
    CGRect newFrame = self.tableView.tableHeaderView.frame;
    newFrame.size.height = newFrame.size.height + 100;
    self.tableView.tableHeaderView.frame = newFrame;

 
 
The height of the tableHeaderView should appear with 200, but appears with 100.
 
If I write:
 
 

    self.tableView.autoresizesSubviews = YES;
    
    
    CGRect newFrame = myHeaderView.frame;
    newFrame.size.height = newFrame.size.height + 100;
    myHeaderView.frame = newFrame;
    
    
    self.tableView.tableHeaderView = myHeaderView;
    self.tableView.tableFooterView = myFooterView;

 
 
Then it starts with 200 of height, as I want. But I want to be able to modify it in runtime.
 
I&#39;ve also tried this, without success:
 

    self.tableView.autoresizesSubviews = YES;
    
    self.tableView.tableHeaderView = myHeaderView;
    self.tableView.tableFooterView = myFooterView;
    
    CGRect newFrame = self.tableView.tableHeaderView.frame;
    newFrame.size.height = newFrame.size.height + 100;
    self.tableView.tableHeaderView.frame = newFrame;
    
    [self.tableView.tableHeaderView setNeedsLayout];
    [self.tableView.tableHeaderView setNeedsDisplay];
    [self.tableView setNeedsLayout];
    [self.tableView setNeedsDisplay];

 
The point here is: **How do we resize a tableHeaderView in runtime ???**
 
Have anyone able to do this?
 
Thanks

I would like to customize both the background and the border color of a grouped-style UITableView.

I was able to customize the background color by using the following:

    tableView.contentView.backgroundColor = [UIColor greenColor];

But the border color is still something I don&#39;t know how to change.

I&#39;m trying to do that for a couple of days now, and after reading tons of messages of people trying to do that too, I&#39;m still unable to have a fully working `UITextField` in some of my `UITableViewCells`, just like in this example: 



![Screenshot][1]

Either I have the form working but the text is not visible (although I set its color to blue), the keyboard goes on the field when I click on it and I haven&#39;t been able to correctly implement the keyboard events.
I tried with a bunch of examples from Apple (mainly `UICatalog`, where there is a kinda similar control) but it&#39;s still not working correctly.

Can somebody help me (and all the people trying to realize this control) and post a simple implementation of a `UITextField` in a `UITableViewCell`, that works fine?

Having a UITextField in a UITableViewCell

I am able to design custom UITableViewCells and load them just fine using the technique described in the thread found at [http://forums.macrumors.com/showthread.php?t=545061][1].  However, using that method no longer allows you to init the cell with a reuseIdentifier which means you have to create whole new instances of each cell at every call.  Has anyone figured out a good way to still cache particular cell types for reuses, but still be able to design them in Interface Builder?
