How to create a UIButton to appear same effect as UIBarButtonItem?

I want to create a UIBu开发者_JS百科tton, but same appearence of a UIBarButtonItem. How to do it??

Found this useful

Outside of a navigation bar, the only way to create a button with the same style as a UIBarButton is to actually create the necessary background images yourself. There is no class that you may use for this (there is a class, obviously, but it's considered private API and using it will get your app rejected).

You can do it by setting the renderMode on the button's image to UIImageRenderingModeAlwaysTemplate. That will make it inherit the tintColor of its ancestor view.

Here's how to do it in Swift (for one control state, anyway):

if let i = myBtn?.imageForState(UIControlState.Normal) {
    if i.renderingMode != UIImageRenderingMode.AlwaysTemplate {
        let newImage = i.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
        myBtn?.setImage(newImage, forState: UIControlState.Normal)
    }
}

I found this via another forum .. a GradientButton class.

Might be a little late but in case someone comes accross this, there is also another possiblity without using images. I use QuartzCore instead.

This is what i do:

MyUIButton.h

#import <QuartzCore/QuartzCore.h>

@interface MyUIButton : UIView { //i think you can also subclass from UIButton, but i use a view to be more flexible

    UIButton *_myInnerButton;
}

- (void) addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents;

- (void) removeTarget:(id) target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents;

@end

MyUIButton.m

#import "MyUIButton.h"

@implementation MyUIButton


- (void) dealloc {

    if (_myInnerButton != nil) {

        [_myInnerbutton removeFromSuperview];

        _myInnerbutton = nil;
    }

    [super dealloc];
}

- (id) initWithFrame:(CGRect)frame {

    self = [super initWithFrame:frame];

    if (self) {

        self.clipsToBounds = YES;


        _myInnerButton = [UIButton buttonWithType:UIButtonTypeCustom];

        [self addSubview:_myInnerButton];


        CGRect innerButtonRect = CGRectZero;

        innerButtonRect.size = self.frame.size;

        _myInnerButton.frame = innerButtonRect;


        CGRect iOSLookalikeViewRect = innerButtonRect;

        iOSLookalikeViewRect.origin.height = -innerButtonRect.size.height/2;


        UIView *iOSButtonView = [[UIView alloc] initWithFrame:iOSLookalikeViewRect];

        iOSButtonView.layer.cornerRadius = 3;

        [self insertSubview:iOSButtonView belowSubview:_myInnerButton];

        UIColor *whiteColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:0.3];

        UIColor *whiteColor2 = [UIColor colorWithRed:1 green:1 blue:1 alpha:0.1];

        [self setGradientColors:[NSArray arrayWithObjects:whiteColor.CGColor, whiteColor2.CGColor, nil] forView:iOSButtonView];

        [iOSButtonView release];
    }

    return self;
}

- (void) setGradientColors:(NSArray*) gradientColors forView:(UIView*) view {

    CAGradientLayer *gradient = [CAGradientLayer layer];
    gradient.frame = view.bounds;
    gradient.colors = gradientColors;
    gradient.cornerRadius = view.layer.cornerRadius;

    [view.layer insertSublayer:gradient atIndex:1];

    [view.layer setRasterizationScale:[UIScreen mainScreen].scale]; //Optional for performance issues, can be removed also
}

//Implementation of the public methods not included, but just asign the methods to the _myInnerButton
@end

Hope it helps someone
