Im having some issues styling my MKAnnotation callout bubble. Originally I had a standard callout that consisted of just a title, subtitle and leftCalloutAccessoryView. This created the following callout:
This worked fine until it was decided that the subtitle should also contain a series of five images that show the business's average ratting among user reviews. This was done by creating a separate view and passing it as the detailCalloutAccessoryView. This produced the following callout bubble:
For some reason when the view is passed to the detailCalloutAccessoryView the callout view is given a weird border around all UI components that create unwanted whitespace around the leftCalloutAccessoryView and between the title and subtitle. How can I remove this white space? I want the business's average ratting inside the subtitle and proper spacing between the title and detailCalloutAccessoryView. How can this be achieved? Is it possible to do so without creating the callout from scratch?
Without code, it is hard to give a detailed answer.
But I found a hint that may solve your problem in this post:
Apparently, MapKit sets translatesAutoresizingMaskIntoConstraints to false, when you set a view to detailCalloutAccessoryView.
This means that you have to set auto layout constraints by your own.
I suggest you create one custom pin representing the Bubble (BubblePin), and each time the user selects one regular pin, you add the BubblePin at the same position of the last selected regular pin.
So adding one additional pin and switching its position according to the user selection will solve the problem, just make sure to add the BubblePin some offset so it won't be right on top of the regular one.

I am a beginner and just started learning iOS. I want to achieve this layout, using Swift:
When you drag a text field into your project, there's a number of styling options available in the Utilities bar in Xcode, that can help you style the shape, colour and other properties of your field. To achieve the look you want, you could use something like this:
Place a UITextField and a UIButton on your story board. Then select both items, and then go to Editor, Embed In, stack view. If they are one on top of the other, change the stack view orientation to vertical then they will be side by side as shown above. Next change the attributes of both in the attributes inspector to taste. You can change the attributes manually in code using textField.defaultTextAttrubutes = [ "the look you are going for"], but you should need to in order to recreate your example.
you can add a view container to your view, inside that container .. add a button and a textfield then add positioning constraints on them.
as you can see in the picture .. it illustrates the idea .. you can style it the way you want e.g. change the height of your textfield .. change its border style etc. the same with your button.
example
In order to add a border, you have to enter some specific information in the attributes inspector. Here is a snapshot of what you can use to create border radius if you want one, vary the thickness of the border, and select a color for the border. screenshot of attributes inspectorYou can vary the values to make the radius greater and the width thicker also, plus you can change the color. Pay very close attention to the spelling otherwise this won't work.
I am creating a screen of an application that contains inside a custom cell one pageControll. It is already working properly but by default his marker comes down the contentView. How can I make the marker in the position I say? In case a little but within the above contentView
this is my screen:
I can think of two possible solutions.
Instead of adding the pageControl to the the cell's content view, add it instead as a child of the red view you have there.
In interface build add a constraint between the bottom of the content view and the pageControl.
Either should achieve the result you're looking for, if I understand you correctly.
This might be a simple question but using storyboard I can't seem to position my table, a message field and a button correctly. In the picture below, if it's positioned that way, only then do I get to see the text field and button at the bottom of the screen and the table view takes up the rest of the screen. If I drag the text field and button to the bottom and resize the table, the text field and button disappear and the table is cut off. Why is that? Is there a solution to this without doing it programmatically?
Easy solution is to remove all constraints then position them where you want them.
You'll find you get different effect when try to reposition items depending where you drag from for example double tap an item and nudge it with arrow keys or grab the middle to move it resizing via the corners.
But in my opinion it's easier remove all constraints from the view and then set them as you go.
Also you might want to consider using a container view for the table view and have a separate UItableViewController that way you can easily separate out that the tableview logic from the other ViewController. It will help stop things getting a little messy later on as project grows.
I'm trying to create a custom accordion-list. On tap it should expand the tapped line and the next lines should change their position relative to the expanded one. By tapping it again it should contract. By tapping another non-expanded line, the expanded line should contract and the tapped one should expand.
I tried to solve this by using subviews with TapGestureRecognizers. I have a undefined number of lines. On tap I change the height of the tapped line and rearrange the position of the following lines manually. Now, it's getting really confusing to handle all possibilities of expanding/contraction/positioning. I'm looking for a more comfortable way to handle this.
Is there any way to align the subviews vertically so that the positions of the lines change automatically if one height changes?
I think a better solution is to use the tableView where the cells will contribute your custom view.Positioning and all will be handled by tableview itself.
If you are working with iOS 6, this should be pretty easy with constraints. Specify that each view is to be located a certain distance from the bottom of the one above it, and when the ones above it move or expand or contract, that constraint should force everything else to move to keep the gap you specified.
EDIT: I just realized that you mentioned in your OP that you may not know for sure how many views you are going to need ahead of time. That probably makes the table view method others have suggested more favorable. It is still possible to do with constraints though (and I found a pretty detailed tutorial here that goes over everything).
I would like to know how to implement the slider similar to the one in the Ipad default calendar application. I have attached the image below
If you see at the bottom, it acts like a slider which allows us to select any month either by just pressing it or sliding to it.
It would be great if anyone could tell me the name of that control. I tried using UISlider but I see that it allows only 3 options:
setThumbImage
setMinimumTrackImage
setMaximumTrackImage
If that control is indeed a slider control, could anyone tell me how I would be able to insert multiple images/ text
Thanks
It may be more complex than you'd like, but you could make your own:
Make a background that has UILabels for the dates
Make a selection box
In the UIViewController you could put something such as:
touchesMoved -
Make the selection box's x value equal to the touch
touchesEnded -
Make the selection box's x value equal to the touch's last x value
The touches moved would allow dragging of the selection box, and the touchesEnded would allow tap selection.
Then you would simply animate the selection box to the x value.
(This is an extremely simplified version, but you could do this pretty easily.)
This can be achieved by using UIScrollView. Add UIButtons programmatically having background images and text as well on them as per your requirement.
You can refer tutorial1 tutorial2 in which on screen only 1 page(Image) is displayed. You need to do some calculation for applying same logic to fit your requirement. i.e. Your scrollview will be smaller(in height) and bigger(in width) as displayed in image, you will be adding UIButtons in spite of images and most important at a time displaying more than 1 item but it won't be difficult. The Main part is only programmatically scrolling.
