How to test if a point is in a view
(5 answers)
Closed 9 years ago.
I am wondering how to check if a view's center is in the frame of another UIView?
Example: if I have a circle which can be dragged by your finger and it's center point gets dragged to a square's frame some code gets executed?
Thanks in advance,
Best regards!
You should have a look at Apple's CGGeometry Reference. In particular, you could use CGRectContainsPoint.

How to make marquee UILabel / UITextField / NSTextField

Closed 8 years ago.
is it possible to create continuous horizontal scrolling for UILabel in Objective-C.
The code in HTML would look like this, so you can get a better idea what I'm talking about.
<marquee behavior="scroll" direction="left">Scrolling text goes here</marquee>
Thanks!
There's no built in control that provides this functionality. You may want to take a look at the open source project MarqueeLabel, which is a subclass of UILabel that adds support for this effect.
Closed. This question needs debugging details. It is not currently accepting answers.

The tableview isn't stretching all the way vertically in iPhone 6 or iPhone 6 Plus.
Any ideas why this is happening? Thanks!

UPDATE:
This question was actually really helpful in another thing to check for as to why the tableview was getting cut off: Why is my UITableView cut off in iOS 7?
There's a whole bunch of things you want to check for if your Table View Cell are getting cut off:
- are they pinned to superview or content view?
- are the constraints such that you are cutting off content without knowing it?
- is a navigation bar or tab bar cutting off content?
- check the auto resizing mask or add one if need be settingsTable.autoresizingMask &= ~UIViewAutoresizingFlexibleBottomMargin;
And multiple other reasons. Its tricky, so if you come across this Q+A and need help, just drop a note and will help!
Select your tableView and pres Pin (a litte square icon with lines on the sides down in Xcode). Then add the bottom constraint (click here, it will turn red) and set value 0. Enjoy

Disable window stretching Cocoa?

Hello I was wondering if anyone knew of a method or way that you stop the user resizing your window for a Cocoa / Mac OS X application.
If this is not not possible how would you go about resizing the window uniformally.
Set the min and max sizes to the desired size.
CGSize fixedSize = myWindow.frame.size;
[myWindow setMinSize:fixedSize];
[myWindow setMaxSize:fixedSize];

How to apply blur to a UIView?
(5 answers)
Closed 9 years ago.
I have a UITableView and UIView (orange). I need that when I scroll a table, under orange area my table has a blurred. Can everybody help me? Thanks.
You could do it like described here: Apply blur to UIView
But blurring is computationally intensive, and scrolling performance will most likely be bad.
Make the orange view over the tableview, then set it's opacity.

How do I create a round cornered UILabel on the iPhone?
how to use rounded corner label in iphone,UILabel Round Corners
Still pretty much getting started with Xcode and Interface Builder. I made a UI screen with several 'label' fields to display random data. But when I change the label color from the screen background color, it looks awful because they're perfect squares. Is there a way to round the corners for labels?
Thanks!
Quoting from another SO answer:
iPhone OS 3.0 and later supports the cornerRadius property on the CALayer class. Every view has a CALayer instance that you can manipulate. This means you can get rounded corners in one line now:
That post has a pretty detailed description of how to implement this behavior.
