Please Help Me Intepret This Code SWIFT
(4 answers)
Closed 4 years ago.
I was reading through an article about BSP (Binary space partitioning) because I am looking to implement it into my project. I came across this line of code:
let max:Int = (splitH ? height : width) - Int(min)
Where splitH is a Boolean value and height/width are integers. What is this line doing? What calculation is it making? I have never seen anything like this in swift.
More specifically, what is this operation: (splitH ? height : width)
if splitH is true, it picks height otherwise it picks width, and then subtracts the value Int(min) from the picked value.
Its usual syntax is conditional ? statement if conditional is true : statement if conditional is false

Improve this question
This is what my graph currently looks like.
I am trying to put the axis labels on the right side of the left axis in ios charts by danielgindi as seen in the second picture above. Any suggestions, I have checked countless forums and posts send help.
As per your requirement you can use below property to get your YAxis labels inside chart.
Swift :
lineChartView.leftAxis.labelPosition = .insideChart
lineChartView.rightAxis.labelPosition = .insideChart
Objective-C:
self.lineChart.leftAxis.labelPosition = YAxisLabelPositionInsideChart;
self.lineChart.rightAxis.labelPosition = YAxisLabelPositionInsideChart;
Hope this will helps!

"f" after number

This must be in documentation somewhere but I cannot find it. What does the .f mean when defining rectangles using CGSizeMake as in CGSizeMake(200.0f, 100.0f);?
.f means that value is float.
if you write directly 1.0 it is initialized as double.
to use less space 1.0f is better.

UISlider how to set the initial value
I want to set the default value for my slider and start the thumb of the slider from that value only.
Any suggestions???
Thanks,
You can set the lowest potential value via the minimumValue method, the highest via the maximumValue method and the current value via the value method, all of which expect the value to be expressed as a float between 0.0 and 1.0.
See the UISlider class reference docs for more information.
