Swift Usage

Add CustomActivityIndicator.swift to your project

In order to show the activity indicator call show from your view controller. Default values are provided for all parameters so you only have to pass the values you want to change.

Note: If you pass in a string for the label text you cannot set the size of the activity indicator since that will be determined by the length of the string

Showing Activity Indicator

CustomActivityIndicator.shared.show(uiView: self.view)
CustomActivityIndicator.shared.show(uiView: self.view, animated: true)
CustomActivityIndicator.shared.show(uiView: self.view, animated: true, duration: 0.5)
CustomActivityIndicator.shared.show(uiView: self.view, backgroundColor: .red)
CustomActivityIndicator.shared.show(uiView: self.view, size: 200)
CustomActivityIndicator.shared.show(uiView: self.view, backgroundColor: .black, size: 100)
        
CustomActivityIndicator.shared.show(uiView: self.view, labelText: "Your Text Here")
CustomActivityIndicator.shared.show(uiView: self.view, labelText: "Your Text Here", backgroundColor: .red)
CustomActivityIndicator.shared.show(uiView: self.view, labelText: "Your Text Here", textColor: .red)
CustomActivityIndicator.shared.show(uiView: self.view, labelText: "Your Text Here", backgroundColor: .black, textColor: .red)

In order to hide the activity indicator call hideActivityIndicator from your view controller. Default values are provided for all parameters so you only have to pass the values you want to change.

Hiding Activity Indicator

CustomActivityIndicator.shared.hide(uiView: self.view)
CustomActivityIndicator.shared.hide(uiView: self.view, animated: true)
CustomActivityIndicator.shared.hide(uiView: self.view, animated: true, duration: 2.0)

Objective-C Usage

Add CustomActivityIndicator.h and CustomActivityIndicator.m to your project. Import CustomActivityIndicator.h in the view controllers where you want to use the activity indicator

#import "CustomActivityIndicator.h"

In order to show the activity indicator call show from your view controller.

Note: If you pass in a string for label text you cannot set the size of the activity indicator since that will be determined by the size of the label needed to display the string passed in.

Showing Activity Indicator

[CustomActivityIndicator.shared show:self.view];
[CustomActivityIndicator.shared show:self.view backgroundColor:UIColor.darkGrayColor size:80.0 duration:1.0];
[CustomActivityIndicator.shared show:self.view backgroundColor:UIColor.darkGrayColor textColor:UIColor.whiteColor labelText:@"Loading user data" duration:1.0];

In order to hide the activity indicator call hideActivityIndicator from your view controller.

Hiding Activity Indicator

[CustomActivityIndicator.shared hide:self.view];
[CustomActivityIndicator.shared hide:self.view duration:1.0];
