since iOS 7 my textField will not get "shadowed" as it did in earlier versions of iOS automatically. I would like to add an innerShadow in the textfield. Which is the best approach to do so since iOS 7 ? The code below is how i code my textField. You can see the difference between iOS 7 and iOS 6 here: http://tinypic.com/view.php?pic=2ufewx0&s=5#.Uksu6hbU-8V
UITextField* sbTextField;
//[sbTextField removeFromSuperview];
for (UIView *subView in self.searchBar.subviews){
for (UIView *ndLeveSubView in subView.subviews){
if ([ndLeveSubView isKindOfClass:[UITextField class]])
{
sbTextField = (UITextField *)ndLeveSubView;
sbTextField.backgroundColor =[UIColor whiteColor];
self.navigationItem.titleView = sbTextField;
self.navigationItem.rightBarButtonItem = menuButton;
// [sbTextField removeFromSuperview];
break;
}
}
}
you could try this approach and make the radius negative (I'm just guessing). Also if its inside a superview thats animated (such as a tableview) this can cause rendering problems and make it very slow.

I would really like to change the color of the "Search" button on the keyboard to match the theme of my app. But if that is not possible, at least I would like to do
self.searchBar.keyboardAppearance = UIKeyboardAppearanceDark;
But that does not work because, as I guess, the searchBar is not a UITextField. So how might I do this successful? I mean, change the color of the "Search" on the keyboard: whether fully or just the dark theme.
For iOS 8 use
self.searchBar.keyboardAppearance = UIKeyboardAppearance.Dark
Try this, it works with IOS 6 , IOS 7 and IOS 8:
[self setKeyboardOnSearchBar:self.searchBar];
And the function:
-(void)setKeyboardOnSearchBar:(UISearchBar *)searchBar
{
for(UIView *subView in searchBar.subviews) {
if([subView conformsToProtocol:#protocol(UITextInputTraits)]) {
[(UITextField *)subView setKeyboardAppearance:UIKeyboardAppearanceAlert];
[(UITextField *)subView setReturnKeyType:UIReturnKeySearch];
} else {
for(UIView *subSubView in [subView subviews]) {
if([subSubView conformsToProtocol:#protocol(UITextInputTraits)]) {
[(UITextField *)subSubView setReturnKeyType:UIReturnKeySearch];
[(UITextField *)subSubView setKeyboardAppearance:UIKeyboardAppearanceAlert];
}
}
}
}
}
Try the following
for(UIView *subView in self.searchBar.subviews) {
if([subView conformsToProtocol:#protocol(UITextInputTraits)]) {
[(UITextField *)subView setKeyboardAppearance: UIKeyboardAppearanceDark];
}
}
Swift 4 update, iOS 11+ :
searchBar.keyboardAppearance = .dark
searchBar.keyboardAppearance = .light
searchBar.keyboardAppearance = .default
Swift 5, iOS 14:
If Search bar is present inside a specific view (eg- SearchBarView),
UITextField.appearance(whenContainedInInstancesOf: [SearchBarView.self]).keyboardAppearance = .dark
Will cause change only for the specific search bar inside the SearchBarView.
Else if you want to do for all Search Bars then,
UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).keyboardAppearance = .dark
I am working on IOS 7 application.By default its appearing like Pic(1).But I need to change it as Pic(2).I googled and found few answers for the requirement,but it has not changed.Or else I need to hide.So that I can manage with background image.This is first image
I used below code to modify it.But didnt succeed.
In .h file
#property(nonatomic,strong) IBOutlet UISearchBar *findSearchBar;
In .m file
#synthesize findSearchBar;
- (void)viewDidLoad
{
[super viewDidLoad];
[self setSearchIconToFavicon];
}
- (void)setSearchIconToFavicon
{
// The text within a UISearchView is a UITextField that is a subview of that UISearchView.
UITextField *searchField;
for (UIView *subview in self.findSearchBar.subviews)
{
if ([subview isKindOfClass:[UITextField class]]) {
searchField = (UITextField *)subview;
break;
}
}
if (searchField)
{
UIView *searchIcon = searchField.leftView;
if ([searchIcon isKindOfClass:[UIImageView class]])
{
NSLog(#"aye");
}
searchField.rightView = nil;
searchField.leftView = nil;
searchField.leftViewMode = UITextFieldViewModeNever;
searchField.rightViewMode = UITextFieldViewModeAlways;
}
}
I am not getting how to make the center of the view's image to nil.Its really killing my time.Please help me.where I had gone wrong.
UITextField *txfSearchField = [looksearchbar valueForKey:#"_searchField"];
[txfSearchField setBackgroundColor:[UIColor whiteColor]];
[txfSearchField setLeftViewMode:UITextFieldViewModeNever];
[txfSearchField setRightViewMode:UITextFieldViewModeNever];
[txfSearchField setBackground:[UIImage imageNamed:#"searchbar_bgImg.png"]];
[txfSearchField setBorderStyle:UITextBorderStyleNone];
//txfSearchField.layer.borderWidth = 8.0f;
//txfSearchField.layer.cornerRadius = 10.0f;
txfSearchField.layer.borderColor = [UIColor clearColor].CGColor;
txfSearchField.clearButtonMode=UITextFieldViewModeNever;
Try this may be it will help u........
I'm not sure how to left-align the placeholder, but as of iOS 5.0 there's a simple, supported way to modify the search bar's text field properties, e.g.:
[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setLeftViewMode:UITextFieldViewModeNever];
which will hide the magnifying glass icon.
You could try:
searchBar.setImage(UIImage(named: "yourimage")!, forSearchBarIcon: UISearchBarIcon.Clear, state: UIControlState.Normal)
//Set all cancel buttons in search bars to "Done"
id searchBarButton = [UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil];
if([[[UIDevice currentDevice] systemVersion] floatValue] < 7) {
[searchBarButton setTitle:#"Done"];
} else {
//Can't do anything here or i get EXC_BAD_ACCESS
}
This is giving a EXC_BAD_ACCESS when called in viewDidLoad only on iOS 7 Gold Master and newer. iOS 7 beta 6 and older is fine.
Is there a different way to do this in iOS 7?
NSLog("%#", searchBarButton) results in this on iOS7:
2013-10-01 16:14:25.972 MP Staging[12293:a0b] <_UIBarItemAppearance:0x1aaf72d0> <Customizable class: UIBarButtonItem> when contained in (
UISearchBar
) with invocations (null)>
and this on iOS 6
<_UIBarItemAppearance: 0x1c671aa0>
setTitle will fail in iOS7.
Try below code from this blog:
-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
self.searchDisplayController.searchBar.showsCancelButton = YES;
UIButton *cancelButton;
UIView *topView = self.searchDisplayController.searchBar.subviews[0];
for (UIView *subView in topView.subviews) {
if ([subView isKindOfClass:NSClassFromString(#"UINavigationButton")]) {
cancelButton = (UIButton*)subView;
}
}
if (cancelButton) {
//Set the new title of the cancel button
[cancelButton setTitle:#"Annuller" forState:UIControlStateNormal];
}
}
I'm using this without any problems in 7.1, however, it does seem to crash on 7.0.x (device and sim) - hopefully this means they've brought the property back in 7.1, but it also means that we have to use one of the above subview traversing hacks for the interim versions.
id barButtonAppearanceInSearchBar = [UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil];
[barButtonAppearanceInSearchBar setTitleTextAttributes:#{NSFontAttributeName:[UIFont fontWithName:#"HelveticaNeue" size:15],
NSForegroundColorAttributeName : [UIColor blackColor]
} forState:UIControlStateNormal];
[barButtonAppearanceInSearchBar setTitle:#"Done"];
UIBarButtonItem's title property is not available through the UIAppearance proxy.
I don't know why it was working in iOS 6, but it's definitely not supposed to.
The only alternative you seem to have is to "hack" the UISearchBar by crawling its subviews looking for the button and setting the title, but:
it's very fragile, as any implementation change to the subviews structure will break your code
it's not global you will have to do this on any UISearchBar instance
According to this answer you can perform this "hack" in the searchDisplayControllerWillBeginSearch: method of UISearchDisplayDelegate like follows:
- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
[theSearchBar setShowsCancelButton:YES animated:NO];
UIButton *cancelButton;
UIView *topView = theSearchBar.subviews[0];
for (UIView *subView in topView.subviews) {
if ([subView isKindOfClass:NSClassFromString(#"UINavigationButton")]) {
cancelButton = (UIButton*)subView;
}
}
if (cancelButton) {
[cancelButton setTitle:#"YourTitle" forState:UIControlStateNormal];
}
}
I created a search bar programmatically and added to my view using the codes below:
- (void)viewDidLoad
{
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)];
UIView *bg = [[searchBar subviews] objectAtIndex:0];
searchBar.delegate = self;
searchBar.placeholder = #"Search record";
for(UIView *view in searchBar.subviews){
if([view isKindOfClass:[UITextField class]]){
UITextField *tf = (UITextField *)view;
tf.delegate = self;
break;
}
}
[bg removeFromSuperview];
[self.view addSubview: searchBar];
}
The code is implemented with UISearchBarDelegate and UITextFieldDelegate.
I have tried using
- (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar
{
NSLog(#"cancel clicked");
searchBar.text = #"";
[aSearchBar resignFirstResponder];
}
- (BOOL)textFieldShouldClear:(UITextField *)textField
{
NSLog(#"clear");
[self performSelector:#selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1];
return YES;
}
and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside.
The clear button works when I implemented it in IB. Wonder why?
Kindly advice, many thanks.
This might happen if you position your search bar out of the bounds of a parent view. Then, the touches aren't delivered to your searchBar properly. This also affects text editing controls like copy & paste.
I have checked your code it work fine on device as well as on simulator.
How do remove the gradient from a UIWebView - the one that you see if you overscroll the top or bottom.
This code
webView.backgroundColor = [UIColor whiteColor];
just changes the color of the gradient, it doesn't removes it. How can this be done?
(note: not the same question as UIWebView underside)
Aha, yes terminology fail. I wouldn't call that a shadow at all, but c'est la vie. Here is my type-safe code to achieve the effect. To summarise: this will hide any image-view children of the scroll view. It's not as vulnerable to change as the (objectAtIndex:0) methods, so if Apple re-order the children of the webView control it will work fine, but still relies on the fact that the gradient effect is applied by imageviews parented to the scroll view (and that there is indeed a scrollview underpinning the web view).
{
webView.backgroundColor = [UIColor whiteColor];
for (UIView* subView in [webView subviews])
{
if ([subView isKindOfClass:[UIScrollView class]]) {
for (UIView* shadowView in [subView subviews])
{
if ([shadowView isKindOfClass:[UIImageView class]]) {
[shadowView setHidden:YES];
}
}
}
}
}
To transparent the UIWebView and remove the scrolls.
webView.opaque = NO;
webView.backgroundColor = [UIColor clearColor];
for(UIView *view in webView.subviews){
if ([view isKindOfClass:[UIImageView class]]) {
// to transparent
[view removeFromSuperview];
}
if ([view isKindOfClass:[UIScrollView class]]) {
UIScrollView *sView = (UIScrollView *)view;
for (UIView* shadowView in [sView subviews]){
//to remove shadow
if ([shadowView isKindOfClass:[UIImageView class]]) {
[shadowView setHidden:YES];
}
}
}
}
for hide scroll indicators
You mean the shadow? Remove UIWebView Shadow?
The only way I found how to do this was :
for(UIView *aView in [[[webView subviews] objectAtIndex:0] subviews]) {
if([aView isKindOfClass:[UIImageView class]]) { aView.hidden = YES; }
}
It just just steps thru the subviews of UIWebView and removes the view if it is an image view.
I haven't put this in any App Store apps, so I don't know if Apple would accept it.
EDIT: Brian's link provides more details.
Using method suggested above you won't be able to edit your scroll indicator/insets later. They appear as UIImageView also, so you should check for last object:
UIView* lastView = [[subView subviews] lastObject];
for (UIView* shadowView in [subView subviews])
{
if(shadowView!=lastView) ... <-this one is a scroll
}
I was able to do this by adding white subviews to the top and bottom of the WebView’s scrollView. I control the content of the WebView, so I know that white is OK - this won’t work if you are loading arbitrary content.
// _topCover and _bottomCover are ivar UIViews
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
// with cover views 300pt high, I couldn't scroll far enough to see the shadow,
// even in portrait on an iPad, which gives you the longest scroll distance
CGFloat coverage = 300;
_topCover = [[UIView alloc] initWithFrame:CGRectMake(0, -coverage, webView.bounds.size.width, coverage)];
_bottomCover = [[UIView alloc] initWithFrame:CGRectMake(0, webView.scrollView.contentSize.height, webView.bounds.size.width, coverage)];
_topCover.backgroundColor = [UIColor whiteColor];
_bottomCover.backgroundColor = [UIColor whiteColor];
// in case the webView is resized, e.g. by rotating the device
_topCover.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleWidth;
_bottomCover.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleWidth;
[webView.scrollView addSubview:_topCover];
[webView.scrollView addSubview:_bottomCover];
}
I run it it after the page loads so that webView.scrollView.contentSize.height will give me the correct height. I’m not sure how this will work if your pages are dynamically changing height. My page loads only once; if yours is reloading, you will want to skip running alloc/init on _topCover and _bottomCover after the first time for efficiency.
Update: I’m not sure that my use of autoresizingMask, above, is sufficient when the view rotates. You may need to put this in the UIViewController that contains your UIWebView to resize the covers after rotating:
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
CGFloat coverage = 300;
_topCover.frame = CGRectMake(0, -coverage, self.webView.bounds.size.width, coverage);
_bottomCover.frame = CGRectMake(0, self.webView.scrollView.contentSize.height, self.webView.bounds.size.width, coverage);
}
I've built upon #damithH 's answer
#implementation UIWebView (Extensions)
- (void)setBackgroundAndShadowVisible:(BOOL)visible
{
self.opaque = !visible;
self.backgroundColor = [self.backgroundColor colorWithAlphaComponent:visible ? 1.0 : 0.0];
for(UIView *view in [self subviews])
{
if([view isKindOfClass:[UIImageView class]])
{
view.hidden = !visible;
}
if([view isKindOfClass:[UIScrollView class]])
{
UIScrollView *scrollView = (UIScrollView *)view;
for (UIView *shadowView in [scrollView subviews])
{
if ([shadowView isKindOfClass:[UIImageView class]])
{
shadowView.hidden = !visible;
}
}
}
}
}
#end
if (UIDevice.currentDevice.systemVersion.intValue < 7)
