UISearchBar: clear background color or set background image [duplicate]

Answer 1

A future-proof way:

[searchBar setBackgroundImage:[UIImage new]];
[searchBar setTranslucent:YES];

Answer 2

I had problems w/ the answer above. I used the following.

for (UIView *subview in searchBar.subviews) {
    if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
        [subview removeFromSuperview];
        break;
    }
}

Answer 3

You have two questions here:
1.UISearchBar clear background color:
See my answer here

2.Set background image Solution:(If you are in iOS 5.0 +)

[[UISearchBar appearance]setSearchFieldBackgroundImage:[navBarGradImage resizableImageWithCapInsets:inset2] forState:UIControlStateNormal];

NOTE: You can also try using a transparent image as a background.

Hope this helps.

Answer 4

Look here: UISearchbar background image change

Answer 5

I just came up with a solution that works really well. You have to override the UISearchBar and then hide both the Background and Segment Control layers. Then Draw the background.

@ .m

#import "UISearchBar.h" 
#import <QuartzCore/QuartzCore.h>

@implementation UISearchBar(CustomBackground)

- (id)init
    {
        for ( UIView * subview in self.subviews ) 
        {
            if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground") ] ) 
                subview.alpha = 0.0;  

            if ([subview isKindOfClass:NSClassFromString(@"UISegmentedControl") ] )
                subview.alpha = 0.0; 
        } 

        return self;
    }

+ (UIImage *) bgImagePortrait
    {
        static UIImage *image = nil;
        if (image == nil)
            image = [[UIImage imageNamed:@"UISearchBarBack.png"] retain ];

        return image;
    }

+ (UIImage *) bgImageLandscape
    {
        static UIImage *image = nil;
        if (image == nil)
            image = [[UIImage imageNamed:@"UISearchBarBack.png"] retain];

        return image;
    }

- (void) drawLayer:(CALayer *)layer inContext:(CGContextRef)contenxt
    {
        if ([self isMemberOfClass:[UISearchBar class]] == NO)
            return; 

        UIImage * image = ( self.frame.size.width > 320 ) ? [UISearchBar bgImageLandscape ] : [UISearchBar bgImagePortrait ];  

        for ( UIView * subview in self.subviews ) {
            if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground") ] ) 
                subview.alpha = 0.0; 

            if ([subview isKindOfClass:NSClassFromString(@"UISegmentedControl") ] )
                subview.alpha = 0.0; 
        }

        CGContextTranslateCTM( contenxt , 0 , image.size.height );
        CGContextScaleCTM( contenxt, 1.0, -1.0 );
        CGContextDrawImage( contenxt , CGRectMake( 0 , 0 , image.size.width , image.size.height ), image.CGImage );
    }  

@end

@ .h

#import <Foundation/Foundation.h>
#import <QuartzCore/QuartzCore.h>


@interface UISearchBar(CustomBackground) 

@end

Hope this helps!

I prefer to just set the alpha to 0 so you can hide/show on demand.

// Hide
[[self.theSearchBar.subviews objectAtIndex:0] setAlpha:0.0];

// Show
[[self.theSearchBar.subviews objectAtIndex:0] setAlpha:1.0];
