A few classes and categories to help make working with Ion Icons easier (sweetmandm/ionicons-iOS, pod name: 'ionicons'). You don't have to configure size and color on an ad hoc basis anymore; just configure the colors and sizes for each UI element in the settings dictionary on the singleton object of YZIonIconsHelper, then create new UIElements with the additional factory methods.

This is how I used to use 'ionicons':

// View Controller 1
CGFloat size = 22.0;
CGColor color = [UIColor darkGrayColor];

self.navigationItem.leftBarButtonItem =
    [[UIBarButtonItem alloc]
     initWithImage:[IonIcons imageWithIcon:icon_navicon
                                      size:size
                                     color:color
                    ]
     style:UIBarButtonItemStylePlain
     target:self
     action:someSelector
     ];
// View Controller 2
CGFloat size = 22.0;
CGColor color = [UIColor darkGrayColor];

self.navigationItem.leftBarButtonItem =
    [[UIBarButtonItem alloc]
     initWithImage:[IonIcons imageWithIcon:icon_navicon
                                      size:size
                                     color:color
                    ]
     style:UIBarButtonItemStylePlain
     target:self
     action:someSelector
     ];

I don't want to repeat the configurations any more.

CGFloat size = 22.0;
CGColor color = [UIColor darkGrayColor];

With YZIonIconsHelper, configure once,

[YZIonIconsHelper changeSettingsForClass:[UIBarButtonItem class]
                                     key:yz_icon_normal_color
                                   value:[UIColor darkGrayColor]
 ];
[YZIonIconsHelper changeSettingsForClass:[UIBarButtonItem class]
                                     key:yz_icon_size
                                   value:@(22)
 ];

Then:

// View Controller 1
self.navigationItem.leftBarButtonItem = 
    [UIBarButtonItem yz_barButtonItemWithIonIcon:icon_navicon
                                          target:nil
                                          action:nil
     ];

// View Controller 2
self.navigationItem.leftBarButtonItem = 
    [UIBarButtonItem yz_barButtonItemWithIonIcon:icon_navicon
                                          target:nil
                                          action:nil
     ];

No more

CGFloat size = 22.0;

CGColor color = [UIColor darkGrayColor];

How to use?

It is recommended that you use cocoapods to add YZIonIconsHelper. If you've never used CocoaPods, check out their page:

Step 1

1. Add pod 'YZIonIconsHelper' to you Podfile
2. Run pod install command in the directory that contains your Podfile
3. Open the freshly generated xcworkspace file
4. Modify your project's Info.plist file, add ionicons.ttf to Fonts provided by application

Step 2

You can either follow Step 2 on sweetmandm/ionicons-iOS or continue on to follow my instructions (which is copied from sweetmandm/ionicons-iOS anyway)

Modify your project's Info.plist file:

1. Open your project's Info.plist file by clicking on the project in the Navigator on the left, then choosing 'Info'.
2. Under 'Custom iOS Target Properties', click the last Key in the list, then click on the '+' icon.
3. For the new key, type 'Fonts provided by application'.
4. Twirl down the arrow icon, double-tap the right-most box to enter the string value, and type 'ionicons.ttf'.

Step 3

1. Import the code by #import "YZIonIconsHelperImportAll.h"

You are ready to go.

How to prepare the Demo Project?

You have to use cocoapods to prepare the Demo Project.

Since Pods are ignored, you have to run pod install in the demo project directory.

Then open the xcworkspace file.
