this window status bar.How to make the icon has been relying on the right ? Resize the window , it automatically to the right .
-(void)composeInterface{
NSView *themeFrame=[[self.window contentView] superview];
NSRect themeFrameRect = [themeFrame frame];
NSRect accessoryViewFrame =[self.statusBarBtn frame];
NSRect newFrame = NSMakeRect(30,
themeFrameRect.size.height - accessoryViewFrame.size.height,
accessoryViewFrame.size.width,
accessoryViewFrame.size.height);
[self.statusBarBtn setFrame:newFrame];
// [self.statusBarBtn setFrameOrigin:NSMakePoint(0, 0)];
// [self.statusBarBtn setAutoresizingMask:323];
[themeFrame addSubview:self.statusBarBtn];
}
If You want that Your icon will be aligned to the right You need to change it's Autosizing to align right. You need to do it like this in Size Inspector :
Or just use -setAutoresizingMask like this:
[self.statusBarBtn setAutoresizingMask:333]; //NOT 323
Furthermore Your newFrame's x possition is set to 30, so the icon will be in the left side.
Change this:
NSRect newFrame = NSMakeRect(30,
themeFrameRect.size.height - accessoryViewFrame.size.height,
accessoryViewFrame.size.width,
accessoryViewFrame.size.height);
To this:
NSRect newFrame = NSMakeRect(themeFrameRect.size.width - accessoryViewFrame.size.width,
themeFrameRect.size.height - accessoryViewFrame.size.height,
accessoryViewFrame.size.width,
accessoryViewFrame.size.height);

Is it possible to set the height of a UIWebView by doing something like this..
[webView.height: currentHeight - 44px];
So essentially, I want to get the height of the UIWebView and then make it 44px shorter from the bottom, programmatically.
Save your old frame like this:
CGRect oldFrame = WebView.frame;
Then set the new frame :
CGRect newFrame =CGRectMake(oldFrame.origin.x, oldFrame.origin.y, oldFrame.size.width, oldFrame.size.height-44);
[WebView setFrame:newFrame];
Thats it :-)
I guess this should be enough.
webView.frame = CGRectMake(webView.frame.origin.x, webView.frame.origin.y, webView.frame.size.width, webView.frame.size.height - 44);
I have created a paginated UIScrollView with three subviews. It works great when testing on an iPhone 5 in landscape (the orientation I designed at) but it breaks whenever the device resolution changes.
How can I make the frame scale to the correct resolution, no matter the device or orientation?
- (void)viewDidLoad {
CGRect frame;
frame.origin.x = self.scrollView.frame.size.width * i;
frame.origin.y = 0;
frame.size = self.scrollView.frame.size;
}
- (IBAction)changePage {
CGRect frame;
frame.origin.x = self.scrollView.frame.size.width * self.pageControl.currentPage;
frame.origin.y = 0;
frame.size = self.scrollView.frame.size;
[self.scrollView scrollRectToVisible:frame animated:YES];
pageControlBeingUsed = YES;
}
Put your scroll view inside another, custom view. In the custom view, implement layoutSubviews something like this.
#interface ViewScalesOneSubview : UIView
#property UIView *scalingSubview;//subview to scale
#end
#implementation ViewScalesOneSubview
-(void) layoutSubviews {
[super layoutSubviews];
CGRect parentBounds = [self bounds];
CGRect childBounds = [scalingSubview bounds];//unscaled
CGFloat scale = parentBounds.width / childBounds.width;
CGAffineTransform transform = CGAffineTransformMakeScale( scale , scale );
//fiddle with x,y translation to position as you like
scalingSubview.transform = transform;
}
#end
Give the custom view autoresizing so it fits the window or whatever container and changes with rotation. Do not give the scroll view autoresizing, as it will conflict with this custom layoutSubviews. When the custom view changes size, it will scale the scalingSubview to fit. By using the same scale for both axis, it will preserve aspect ratio. You could scale to fit instead, or use height instead of width or whatever.
Edit:
To resize the view, as opposed to scaling the view, set the autoresizing mask.
scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
https://developer.apple.com/library/ios/documentation/uikit/reference/UIView_Class/UIView/UIView.html#//apple_ref/occ/instp/UIView/autoresizingMask
You can also do this in interface builder.
I am trying to change the layout of my UIView programmatically, and not by using Auto Layout, as I am trying to deploy this app for iOS 4 and up. I basically set my view up with the screen height at 455(iPhone 5)(I know the actual screen size is 568 points, but I have a tab bar on the bottom so I am assuming the size shown in IB has taken that into account). I recorded the origin of all of my buttons and labels relative to the longer screen size and programmatically changed them to how I preferred them. The problem is, some of the buttons and labels are going off the screen now, so I think I have to perform some kind of conversion to keep them in bounds, but I am not sure what. See the pictures attached below:
Image before my initMethod is called to change button and label origins
Image after my initMethod is called to change the origin
View properties in XCode for the old screen size
This is how I want the view to Look. I moved the buttons around and recorded the origin of each.
Picture of my init method in viewWillAppear. Notice how the frame of the label is zero.
Here is the code I used:
-(void)initView
{
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height == 480) {
//iphone 4,4s
//done
}else if(screenBounds.size.height == 568) {
//iphone 5
CGRect frame;
//Static Professor label
frame = [staticProfessorLabel frame];
frame.origin.x = 48;
frame.origin.y = 218;
[staticProfessorLabel setFrame:frame];
//Professor Label
frame = [professorLabel frame];
frame.origin.x = 192;
frame.origin.y = 218;
[professorLabel setFrame:frame];
//show button
frame = [showProfessorButton frame];
frame.origin.x = 67;
frame.origin.y = 258;
[showProfessorButton setFrame:frame];
//clear proff button
frame = [clearProfessor frame];
frame.origin.x = 240;
frame.origin.y = 258;
//note label
frame = [bottomNote frame];
frame.origin.x = 160;
frame.origin.y = 310;
[bottomNote setFrame:frame];
//search button
frame = [searchButton frame];
frame.origin.x = 158;
frame.origin.y = 424;
[searchButton setFrame:frame];
//spinner
frame = [actIndicator frame];
frame.origin.x = 266;
frame.origin.y = 424;
[actIndicator setFrame:frame];
}
}
Also, I am calling this in the viewDidAppear method because when I call it in viewDidLoad, none of the buttons and labels give me a valid frame(I am guessing they are not initialized yet).
Your Xcode screenshots show that your storyboard contains constraints, so we can tell that your storyboard has autolayout turned on. If you want to set the view frames directly in code, you have to turn off autolayout.
Take a look at my answer here if you need help turning off autolayout on your storyboard.
Your hard-coded coordinates are simply wrong. Just double-check your values.
For example, bottomNote starts at x 160, which is clearly too far to the right.
Here my dilemma. I have 4 elements inside a UIScrollView.
1. Top most element is a UILabel that I give height dynamically depending upon the amount of content in it.
2. Second is a fixed height UILabel that I give position dynamically depending upon the height given to the upper UILabel
3. Third element is a UIImageView that again I have to give position dynamically depending upon the height given to the topmost UILabel
4. The fourth is a UIWebView, to which I gave both, height & position dynamically. (Height depending upon the content in it.. and position again depending on the height of topmost UILabel)
Finally, I dynamically give height to my UIScrollView to accomodate all of the above elements.
Here is the code I use in - (void)webViewDidFinishLoad:(UIWebView *)webView to accomplish all of the above.
//Adjust height of top-most UILabel
CGSize maximumLabelSize = CGSizeMake(300,9999);
CGSize expectedLabelSize = [item.label1 sizeWithFont:label1.font constrainedToSize:maximumLabelSize lineBreakMode:label1.lineBreakMode];
CGRect newFrame = label1.frame;
newFrame.size.height = 0;
newFrame.size.height = expectedLabelSize.height;
label1.frame = newFrame;
//Adjust position of second UILlabel
CGRect labelPosition = label2.frame;
labelPosition.size.height = 20;
labelPosition.origin.y = expectedLabelSize.height +14;
label2.frame = labelPosition;
//Add UIImageView and adjust it's position
UIImageView *image;
image = [[UIImageView alloc] initWithFrame:CGRectMake(0, expectedLabelSize.height +41, 320, 2)];
image.image = [UIImage imageNamed:#"image.png"];
[scrollView addSubview:image];
[image release];
//Adjust UIWebView height and position
CGRect frame = webView.frame;
frame.size.height = 0;
frame.origin.y = expectedLabelSize.height +48;
webView.frame = frame;
CGSize fittingSize = [webView sizeThatFits:CGSizeZero];
frame.size = fittingSize;
webView.frame = frame;
//Adjust Scrollview height
scrollView.contentSize = CGSizeMake(320, fittingSize.height +expectedLabelSize.height +48);
Finally, my problem is that when I first load this view, everything but the scrollview get's proper height & position. But, if I go back one view & open this view again, the scrollview has the desired height.
Any ideas what I might be doing wrong here?
My guess is that the scrollView variable isn't yet initialized when this first runs. Try setting a breakpoint somewhere in this code and checking if scrollView has a value or if it's just 0x00000000.
I have a scrollview with an image as a subview. I would like to set the boundaries of the scrollview to be the size of the image view, so that you wouldn't be able to see any of the background.
I don't want this happening anymore.
The weird part is, that after you zoom in or out on the image, then the boundaries seem to fix themselves, and you can no longer move the image out of the way and see the background.
This is what I have going for code:
-(UIView *) viewForZoomingInScrollView:(UIScrollView *)scrollView
{
// return which subview we want to zoom
return self.imageView;
}
-(void)viewDidLoad{
[super viewDidLoad];
[self sendLogMessage:#"Second View Controller Loaded"];
//sets the initial view to scale to fit the screen
self.imageView.frame = CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.bounds));
//sets the content size to be the size our our whole frame
self.scrollView.contentSize = self.imageView.image.size;
//setes the scrollview's delegate to itself
self.scrollView.delegate = self;
//sets the maximum zoom to 2.0, meaning that the picture can only become a maximum of twice as big
[self.scrollView setMaximumZoomScale : 2.5];
//sets the minimum zoom to 1.0 so that the scrollview can never be smaller than the image (no matter how far in/out we're zoomed)
[self.scrollView setMinimumZoomScale : 1.0];
[imageView addSubview:button];
}
I thought that this line would solve my problem
//sets the content size to be the size our our whole frame
self.scrollView.contentSize = self.imageView.image.size;
But like I said, it only works after I zoom in or out.
EDIT: When I switch
self.scrollView.contentSize = self.imageView.image.size;
to
self.scrollView.frame = self.imageView.frame;
It works like I want it to (you can't see the background), except the toolbar on the top is covered by the image.
imageView.image.size isn't necessarily the frame of the imageView itself, try setting the
scrollview.frame = imageView.frame
and then
scrollView.contentSize = imageView.image.size
Then you won't see any border. If you want the image to be the maximum size to start with,
do
imageView.frame = image.size;
[imageView setImage:image];
scrollView.frame = self.view.frame; //or desired size
[scrollView addSubView:imageView];
[scrollView setContentSize:image.size]; //or imageView.frame.size
To fix this, I ended up declaring a new CGRect , setting its origin to my scrollView's origin, setting its size with the bounds of my view, and then assigning this CGRect back to my scrollview frame
CGRect scrollFrame;
scrollFrame.origin = self.scrollView.frame.origin;
scrollFrame.size = CGSizeMake(CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.bounds));
self.scrollView.frame = scrollFrame;
