i am currently working on a menu bar application for OS X. I want do display some data in a NSTableView within the menu. I already managed to set the view of the first NSMenuItem to my NSScrollView.
The problem is that i don't know how to set the maximum height for the NSScrollView. I want something similar to the Shazam or Adobe Creative Cloud app: A small menu with a TableView inside it that scrolls but doesn't fill the entire height of the screen.
Here is what i currently have:
The way it works now is that the menu automatically fills the entire screen depending on how much data i put into the TableView.
Here is a screenshot of the way the Shazam app does it:
They display lots of information inside the table but restricted the NScrollView to have a fixed height.
I don't think this is hard to do but i don't know where to look for the option.
Any help would be really appreciated :)
Regards,
Timo
I finally figured it out! I assigned the wrong view to the NSMenuItem.
Now i have two outlets inside my AppDelegate:
#IBOutlet weak var myMenuItem: NSMenuItem!
#IBOutlet weak var myScrollView: NSScrollView!
Inside applicationDidFinishLaunching() i assign the NSScrollView to the view property of the NSMenuItem:
func applicationDidFinishLaunching(aNotification: NSNotification) {
...
self.myMenuItem.view = myScrollView
...
}
The problem i used to have that i set the menu items view to the NSTableView directly, not to the NSScrollView. Everything works fine now.
Thats what the result is looking now:
Exactly what i wanted :)

I have just added a table view for my app settings and for some reason it is not formatting properly.
The content is set to static cells and the style is grouped. I've tried messing around with a few things but I can't get it to display properly.
This is how it should look:
If anyone has any ideas as to why this could be happening, I would very much appreciate the advice.
In ios8 tableView has dynamic content.Use rowHeight explicitly to define rowHeight in your code
self.yourTableView.estimatedRowHeight = 44;
self.yourTableView.rowHeight = 44;
if you want to not use auto layout.Write this in viewDidLoad
or
add constraints to your tableViewCells simplet way is to add from constraint inspector as reset to suggested constraints
and write in viewDidLoad
tableView.estimatedRowHeight = 44
tableView.rowHeight = UITableViewAutomaticDimension
So what I want is I have two ViewControllers in my Storyboard, one is supposed to be displayed when the current pageControl page is 0, the other one is for page 1.
Let's say I have AViewController and BViewController, both are from the same class TestViewController. I have properties from both classes in my TestViewController.h file, so that works. It loads AViewController but when I try to display BViewController nothing happens. I know I can do this by using multiple View but that can be confusing so two ViewController in my Storyboard does seem like a good solution. What I've tried to display the view is adding it as a subview, i also set the frame programmatically and setHidden = false, i also created another view and sub viewed the table into the view and then this view into the original one but nothing has worked so far. Now I'm wondering is that even possible and how'd I do this?
I have a view that needs to have its frame manipulated programmatically - it's a kind of document view that wraps to its content which is then scrolled and zoomed around a superview by manipulating the frame origin. Autolayout fights with this at runtime.
Disabling autolayout completely seems a bit harsh because it could reasonably be used to handle layout for the other views. It seems like what I might want is some kind of "null constraint".
I had the same problem. But I have resolved it.
Yes, you can disable auto layout at runtime for a specific UIView, instead of disabling it for the whole xib or storyboard which is set by default in Xcode 4.3 and later.
Set translatesAutoresizingMaskIntoConstraints to YES, before you set the frame of your subview:
self.exampleView.translatesAutoresizingMaskIntoConstraints = YES;
self.exampleView.frame = CGRectMake(20, 20, 50, 50);
I had a similar issue where Autolayout was overriding some of my frame-setting at run time (I had a dynamic view that in some cases pushed a new view controller...pushing and then pressing Back would reset the initial view).
I got around this by putting my manipulation code in viewDidLayoutSubviews of my View Controller. This seems to get called after whatever constraint mojo gets called, but before viewDidAppear, so the user is none the wiser.
Perhaps just setting translatesAutoresizingMaskIntoConstraints to YES (and not adding additional constraints affecting that view) will let you set the frame without fighting the auto layout system.
In iOS 8 you can set an NSLayoutConstraint to be active or not. So if I'm using interface builder, I add all my constraints to an OutletCollection and then activate or deactivate using:
NSLayoutConstraint.deactivateConstraints(self.landscapeConstraintsPad)
NSLayoutConstraint.activateConstraints(self.portraitConstraintsPad)
The particular application I'm using it for here is having different constraints in portrait and landscape mode and I activate/deactivate based on the rotation of the device. It means I can create some complex layout changes all in interface builder for both orientations, and still use auto layout without the verbose auto layout code.
Or you can activate / deactivate using removeConstraints and addConstraints.
I don't know if this will help anyone else, but I wrote a category to make this convenient because I find myself doing this a lot.
UIView+DisableAutolayoutTemporarily.h
#import <UIKit/UIKit.h>
#interface UIView (DisableAutolayoutTemporarily)
// the view as a parameter is a convenience so we don't have to always
// guard against strong-reference cycles
- (void)resizeWithBlock:(void (^)(UIView *view))block;
#end
UIView+DisableAutolayoutTemporarily.m
#import "UIView+DisableAutoResizeTemporarily.h"
#implementation UIView (DisableAutoResizeTemporarily)
- (void)resizeWithBlock:(void (^)(UIView * view))block
{
UIView *superview = self.superview;
[self removeFromSuperview];
[self setTranslatesAutoresizingMaskIntoConstraints:YES];
__weak UIView *weakSelf = self;
block(weakSelf);
[superview addSubview:self];
}
#end
I use it like this:
[cell.argumentLabel resizeWithBlock:^(UIView *view) {
[view setFrame:frame];
}];
Hope it helps.
You can set the translatesAutoresizingMaskIntoConstraints type Boolean, Value Yes in the User Defined Runtime Attributes of the UIView you want in the xib/storyboard.
In my view I had a Label and a Text. The label had pan gesture. The label moves around fine during drag. But when I use the text box keyboard, the label resets its position to the original location defined in auto layout. The issue got resolved when I added the following in swift for the label. I added this in viewWillAppear but it can be added pretty much anywhere you have access to the target field.
self.captionUILabel.translatesAutoresizingMaskIntoConstraints = true
Open project in 4.5
Select storyboard
Open the file inspector
Under Interface Builder Document uncheck 'Use Autolayout'
You can split across multiple storyboards if you want to use autolayout for some views.
For me it worked to create the subview programmatically, in my case the auto layout was messing with a view that I needed to rotate around its center but once I created this view programmatically it worked.
I've encountered a similar scenario, where I joined a project that was initiated with auto-layout, but I needed to make dynamic adjustments to several views. Here is what has worked for me:
Do NOT have views or components laid out in interface builder.
Add your views purely programmatically starting with alloc/init and setting their frames appropriately.
Done.
This happened to me in a project without storyboards or xib files. All 100% code. I had an ad banner at the bottom and wanted the view bounds to stop at the ad banner. The view would resize itself automatically after loading. I tried every resolution on this page but none of them worked.
I ended up just creating a sub view with the shortened height and placed that in into the main view of the controller. Then all my content went inside the sub view. That solved the problem very easily without doing anything that felt like it was going against the grain.
I am thinking if you want a view that is not the normal size that fills the window then you should use a sub view for that.
Instead of disabling autolayout, I would just calculate the new constraint with the frame you are replacing. That appears to me to be the appropriate way. If you are adjusting components that rely on constraints, adjust them accordingly.
For example, if you have a vertical constraint of 0 between two views (myView and otherView), and you have a pan gesture or something that adjusts the height of myView then you can recalculate the constraint with the adjusted values.
self.verticalConstraint.constant = newMyViewYOriginValue - (self.otherView.frame.origin.y + self.otherView.frame.size.height);
[self.myView needsUpdateConstraints];
For those of you who are using auto layout, please check out my solution here. You should be making #IBOutlet's of the constraints you want to adjust and then change their constants.
if it's xib file:
select the .xib file
select the "File's Owner"
show the Utilities
click on: "File Inspector"
Under "Interface Builder Document" disable: "Use Autolayout"
I'm just learning and playing with the apple Seismic XML example
http://developer.apple.com/library/ios/#samplecode/SeismicXML/Introduction/Intro.html
I've got most of it figured out, but the one area I can't get past is, if I want to remove the tableview controller and create a view controller populated with a tableview. I can get the tableview to appear fine, but no matter what I try I can never get it to populate.
In the viewdidload area I can setup the tableview, color the background, do whatever I want to do, but I seem to 'lose' control of it somehow.
In short, would someone please be able to give me the steps involved in correctly changing the tableviewcontroller to a viewcontroller with a tableview in the apple example?
Thank you.
Lian, you need to read the documentation on UITableViewController. http://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/TableView_iPhone/AboutTableViewsiPhone/AboutTableViewsiPhone.html
I'm not sure what you mean by "remove the tableview controller and create a view controller populated with a tableview" or why you would want this configuration. If you're having trouble with populating the tableViewController, you just pass in the data, usually from an NSArray or NSDictionary in the cellForRowAtIndexPath method. You either need to select the UITableViewController template when you create the class file or include the UITableViewDataSource and UITableViewDelegate if you're adding a tableView to a ViewController.
If you mean you want to change the view controller on screen, then you're looking to pop to another view using the navigation controller.
