I have a UIwebview created using nib. I have many controllers accessing this webview(in nib) . For each call from different controllers the size of webview in nib should be changed accordingly.How to implement this programatically?
Thanks in advance
You need only create outlet of this UIWebView in your controller.(and property)
IBOutlet UIWebview *webExample;
#property (nonatomic, strong) IBOutlet UIWebview *webExample;
When in your code send a call to the UIViewWeb you can detect de sender and change the view's frame size.
webExample.layer.frame=CGRectMake(x,y,200,200);

Can somebody tell me why none of the buttons under the "License Agreement View" UIView object in my .xib file are triggering an action? It seems that the Scrollview object is messing up the behavior. When the buttons are directly under the "Scroll View" object (as opposed to the "License Agreement View" UIView object), then they function properly. But, I need to group my buttons under the UIViews as shown in the view hierarchy below.
Here's the view layout:
Here's my view hierarchy:
Here's the corresponding .m file:
#interface MYViewController ()
- (IBAction)licenseAgreementPressed:(id)sender;
- (IBAction)legalDisclaimerPressed:(id)sender;
- (IBAction)privacyStatementPressed:(id)sender;
#property (strong, nonatomic) IBOutlet UIView *licenseAgreementView;
#property (weak, nonatomic) IBOutlet UIButton *legalDisclaimerButton;
#property (strong, nonatomic) IBOutlet UIButton *privacyStatementButton;
#end
#implementation MYViewController
- (IBAction)licenseAgreementPressed:(id)sender
{
NSLog(#"Pressed A");
}
- (IBAction)legalDisclaimerPressed:(id)sender
{
NSLog(#"Pressed B");
}
- (IBAction)privacyStatementPressed:(id)sender
{
NSLog(#"Pressed C");
}
#end
Make sure you have made connection between IBAction(code) and UIButton(in xib) , please check this post How do I name and link an IBAction button created in a storyboard
Did you connect your actions to the elements in interface builder by control-dragging it?
If your actions are connected you will see a little filled out circle on the left of the line in your editor.
Check this tutorial for further information on how to connect your storyboard elements to your code.
It is because none of the buttons are inside the bounds of the license agreement view. A button outside its superview's bounds is untappable.
So the problem was the links, buttons, and text fields were not actually located within the bounds specified the parent views because the original .xib file didn't have the required constraints pinned to those elements. I discovered this by checking the "clip to bounds" checkbox in the Attributes Inspector pane. Whenever "clip to bounds" was checked, the app was NOT displaying any of the above view objects; I could only see links, buttons, and text fields when "clip to bounds" was unchecked but unfortunately, those elements were not clickable at that point. After setting the necessary constraints, however, the view elements were correctly placed within the bounds of their parent views and the text fields, labels, and buttons became clickable. I'm attaching the constraints that I used to fix the problem. Note: the constraints that are not expanded only include a height constraint.
i'm trying to create an ui button with image and text.
What i need is simple:
an image centered on the first row and on another row a label centered.
So i've created an uibutton in my storyboard, set text and background in this way:
But the result isn't good for me.
This is what i have:
and this is what i need:
Can someone help me?
thanks!
EDIT
I've created a custom UIButton in this way:
.h
#import <UIKit/UIKit.h>
#interface MenuButton : UIButton
#property (weak, nonatomic) IBOutlet UIImageView *image;
#property (weak, nonatomic) IBOutlet UILabel *text;
#end
.m
#import "MenuButton.h"
#implementation MenuButton
#end
And in interface builder i create a view with class MenuButton addedd an image and a label and connecting to .h.
Now my question is:
How can i pass to that new button the image and the label in order to instantiate multiple "custom button" with different value inside?
Thanks!
You just create a UIButton subclass.
1)
If you are using IB: then you can create 2 properties in the .h
#property (weak, nonatomic) IBOutlet UIImageView *image;
#property (weak, nonatomic) IBOutlet UILabel *text
next you need to connect all the properties to the objects in the IB
If you are using code the remove the IBOutlet and move the properties to the .m
2)
Now all you need to do is manage the behaviour of the properties.
in IB, just add the autolayout constraints to the subclass and change their constant property value - check this tutorial
in code, you can do this by setting their frame with animation to make them larger/smaller
EDIT
Ok, after reading your update you need to change the subclass from UIButton to UIView.
This way you can add a UIView in your storyboard and add the UImageView & UILable. After doing so you can change the UIView's class to your subclass.
Then, click on the UIView and open the connections inspector. You will see the IBOutlets you have declared in th UIView subclass, you can just drag from the connections inspector to the UIImageView & UILabel to crete the connections
I have created a very simple test environment one Tab Bar Controller and one View Controller with the following structure:
UI TAB BAR Controller ---------> UIScrollView
UIScrollView
View
Scroll View
Label
Label
Label
.h file
#interface rpViewController : UIViewController
#property (strong, nonatomic) IBOutlet UIScrollView *scrollView;
#end
.m file
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
self.scrollView.contentSize = CGSizeMake(320, 1000);
}
If the start entry point for the app is the view with the scroller everything works fine!
If the start entry point is theTab Bar Controller the scroller is not working?
If your going to work purely with Autolayout you should not be doing any direct manipulations of frames, bounds or contentSize. Apple has written a technical note about working with UIScrollView and Autolayout Technical Note TN2154 that you should read.
So to answer the question, if you are going to be using auto layout you cannot manipulate contentSize and expect consistent results.
I just dragged a UIImageview onto a storyboard in xcode 5. I am coming from .NET where this would add an object of type UIImageView to the main form. Is this the way to think about it in IOS? Where do I click in the xcode IDE to get the name of the instance of UIImageView?
You dragged a UIImageView into a storyboard. You need to see which view controller this UIImageView object lives in and then you can connect that UIImageView to an IBOutlet, which is how your view controller (the implementation or code for which you're working on, which also happens to be a subclass of UIViewController) will interact with the UIImageView object.
You have to write a IBOutlet in the corresponding ViewController.h file like this.
#property (nonatomic , strong) IBOutlet UIImageView *myImageView ;
Then in your ViewController.m , use #synthesize after #implementation tag.
Then go back to the Interface Builder and connect the IBOutlet myImageView to your ImageView which you have dragged there. Hope it helps.
I'm using iOS 6 with storyboard and ARC.
I've got on my storyboard a UIView that I want to use for positioning and sizing - I've created an IBOutlet for the control in my controller via the Ctrl drag/drop so I know it's connected.
Now I want to try to reference this UIView from within the controller so I can dynamically create subviews within that UIView, positioned appropriately.
I'm trying to access the UIView from within viewDidLoad as follows
CGRect rect = self.myView.frame;
...but the rect is always coming up as 0, 0, 0, 0. myView is defined in the header file as:
#property (weak, nonatomic) IBOutlet UIView *myView;
I thought that all the controls from the storyboard would already be initialized when you got to viewDidLoad. If this is not the case, where should I put the code to use the frame of the UIView to create my subViews?
Thanks in advance.
