I have a search functionality using UISearchBar that occurs on-the-fly, so I think it would be more obvious to replace that "Search" button on the keyboard with "Done".
Is there a way to do that?
thanks
You can change the keyboardType property of your UISearchBar object. However, there is not a way to change the returnKeyType directly. You may be able to filter down and change it manually. Check the documentation for UISearchBar and see if you can find returnKeyType as that is what you are looking for.
I accomplish it this way:
// -- Basic UISearchBar setup.
self.theSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,320,38)];
[self.theSearchBar setDelegate:self];
[self.view addSubview:self.theSearchBar];
// -- Customize the returnKeyType of the search bar's nested UITextField.
UITextField *searchBarTextField = [[self.theSearchBar subviews] objectAtIndex:1];
searchBarTextField.returnKeyType = UIReturnKeyGo;
Hope that is helpful. This approach (i.e. grabbing a subview by index) may break in the future, but it works fine for now.
for (UIView *view in _searchBar.subviews){
if ([view isKindOfClass:[UITextField class] ]) {
UITextField *searchTf = (UITextField *)view;
searchTf.returnKeyType = UIReturnKeyDone;
}
}
This is working for iOS 6
UITextField *searchBarTextField = [[searchBarObj subviews] objectAtIndex:1];
searchBarTextField.returnKeyType = UIReturnKeyDefault;
[searchBarTextField setEnablesReturnKeyAutomatically:NO];
This is working for iOS 7
for (UIView *subview in self.searchBar.subviews)
{
for (UIView *subSubview in subview.subviews)
{
if ([subSubview conformsToProtocol:#protocol(UITextInputTraits)])
{
UITextField *textField = (UITextField *)subSubview;
[textField setKeyboardAppearance: UIKeyboardAppearanceAlert];
textField.returnKeyType = UIReturnKeyDone;
break;
}
}
}
Don't rely on it being the second subview, use isKindOfClass: method to check. It will be more iOS update proof that way.
for (UIView *subview in self.theSearchBar.subviews) {
if ([subview isKindOfClass:[UITextField class]]) {
[(UITextField *)subview setReturnKeyType:UIReturnKeyGo];
break;
}
}

I want to remove a UITextField/UIButton/UILabel added to a view on the click of button. How can this be achieved in iOS?
To remove you can simply use:
[myTextField removeFromSuperview];
try this one...
Blockquote
UILabel *t1;
NSArray *arr1=[YourView subviews];
for (UIView *v in arr1)
{
if([v isKindOfClass:[UILabel class]])
{
t1 = (UILabel *)v;
if (t1.tag==your_tag)
[t1 removeFromSuperview];
}
}
Blockquote
You can use [myTextField removeFromSuperview]; to get rid of a view.
[myTextField removeFromSuperview]
See UIView documentation.
All controls inherited from UIView.
So you can remove all the controls which added on UIView using like this. By clicking the button action write like this
for(UIView *control in [self.view subviews])
{
[control removeFromSuperview];
}
How to resign a UITextField of UISearchBar? I tried with the below code
UIView * subView;
NSArray * subViews = [self.searchBar subviews];
for(subView in subViews)
{
if( [subView isKindOfClass:[UITextField class]] )
{
((UITextField*)subView).delegate=self;
((UITextField*)subView).returnKeyType=UIReturnKeyDone;
break;
}
}
for (UIView *subview in self.searchBar.subviews)
{
if ([subview conformsToProtocol:#protocol(UITextInputTraits)])
{
[(UITextField *)subview setClearButtonMode:UITextFieldViewModeWhileEditing];
}
}
And added the TextField Delegate method
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
this works but this resigns the keyboard oly if the textfield is not empty. If the textfield is empty then it is not resigning
Use this :
[searchBar resignFirstResponder];
Please do this one...
-(void)searchBar:(UISearchBar *)theSearchBar textDidChange:(NSString *)searchText
{
if (searchBar.text.length == 0)
[searchBar resignFirstResponder];
}
i hope this will work fine.
First set Delegate in .h file like bellow...
#interface yourViewController : UIViewController<UISearchBarDelegate>
and when you want to resign keyboard of UISearchBar simple use bellow line..
[searchBar resignFirstResponder];
UPDATE:
-(BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar{
[self.searchBar resignFirstResponder];
return YES;
}
I need to know how to stop scrolling in a UIwebview in xcode 4?
[[[webView subviews] lastobject] setScrollingEnabled:NO];
The above code does not work because "NSarray" for instance message does not declare a method with selector 'lastobject'. Why is this or is there new code I am unaware of to disable scrolling? Thanks.
UIView* row = nil;
for(row in webView.subviews){
if([row isKindOfClass:[UIScrollView class] ]){
UIScrollView* scrollRow = (UIScrollView*) row;
scrollRow.scrollEnabled = NO;
scrollRow.bounces = NO;
scrollRow.backgroundColor=[UIColor clearColor];
}
}
your code is trying to make assumptions about the order of the subviews that Apple is defining..
Note that with iOS 5 you have direct access to the scroll view.
So if you wanted to maintain compatibility you could do this:
UIScrollView *scrollView = nil;
if ([webView respondsToSelector:#selector(scrollView)]) { //iOS 5+
scrollView = webView.scrollView;
} else { //iOS 4-
for(UIView *view in webView.subviews){
if([view isKindOfClass:[UIScrollView class] ]){
scrollView = (UIScrollView *) view;
break;
}
}
}
scrollView.scrollEnabled = NO;
scrollView.bounces = NO;
scrollView.backgroundColor=[UIColor clearColor];
Simply add this line to viewDidLoad:
myWebView.scrollView.scrollEnabled = NO;
I would set the webview's UserInteractionEnabled property to NO so that it cannot be scrolled.
In my application I have to add a search bar at the head of the tableview. I am able to add the searchbar but problem is without adding default search bar of ios can i add my customize search bar?? I am giving an image to see what types of search bar will be there...
you can subclass the UISearchBar and override the layoutSubviews method :
- (void)layoutSubviews {
UITextField *searchField;
NSUInteger numViews = [self.subviews count];
for(int i = 0; i < numViews; i++) {
if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?
searchField = [self.subviews objectAtIndex:i];
}
}
if(!(searchField == nil)) {
searchField.textColor = [UIColor whiteColor];
[searchField setBackground: [UIImage imageNamed:#"yourImage.png"] ];
[searchField setBorderStyle:UITextBorderStyleNone];
}
[super layoutSubviews];
}
Also you can :
//to clear searchbar backgraound
- (void) clearSearchBarBg
{
for (UIView *subview in theSearchBar.subviews)
{
if ([subview isKindOfClass:NSClassFromString(#"UISearchBarBackground")])
{
[subview removeFromSuperview];
break;
}
}
}
//display showSearchButtonInitially in a keyboard
- (void)showSearchButtonInitially
{
UIView * subview;
NSArray * subviews = [theSearchBar subviews];
for(subview in subviews)
{
if( [subview isKindOfClass:[UITextField class]] )
{
NSLog(#"setEnablesReturnKeyAutomatically");
[((UITextField*)subview) setEnablesReturnKeyAutomatically:NO];
((UITextField*)subview).delegate=self;
[((UITextField*)subview) setEnabled:TRUE];
((UITextField*)subview).borderStyle = UITextBorderStyleNone;
break;
}
}
}
Look for Apple DOC for UISearchBar
You have bunch of methods there to get whatever you want
You can get UITextView Inside the search bar by
UITextField *textField = [searchBar.subviews objectAtIndex:2];
if ([textField isKindOfClass:[UITextField class]]) {
//Do your customization
}
Again look for AppleDoc for UITextField. You have bunch of methods for that also.
Yeah definitely. You can make your custom search bar (which is a sub-class of UIView) and add it as subview to the tableHeaderView.
[[searchBarDesign.subviews objectAtIndex:0] removeFromSuperview];
here searchBarDesign is my searchBar name.
I think it's better just set all properties of UISearchBar when it is loaded.
#interface MySearchBar : UISearchBar
#end
#implementation MySearchBar
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self myInitialize];
}
return self;
}
-(void)awakeFromNib
{
[super awakeFromNib];
[self myInitialize];
}
-(void)myInitialize
{
self.backgroundImage = [UIImage imageNamed:#"image.png"];
for (UIView* subview in self.subviews) {
if ([subview isKindOfClass:[UITextField class]]) {
//customize text field
UITextField* textfield = (UITextField*) subview;
}
}
}
#end
In the UISearchBar control, is the a way to change the Search key title for the keyboard to Done?
For a searchbar named tablesearchbar:
// Set the return key and keyboard appearance of the search bar
for (UIView *searchBarSubview in [tableSearchBar subviews]) {
if ([searchBarSubview conformsToProtocol:#protocol(UITextInputTraits)]) {
#try {
[(UITextField *)searchBarSubview setReturnKeyType:UIReturnKeyDone];
[(UITextField *)searchBarSubview setKeyboardAppearance:UIKeyboardAppearanceAlert];
}
#catch (NSException * e) {
// ignore exception
}
}
}
At least for iOS 8, simply:
[self.searchBar setReturnKeyType:UIReturnKeyDone];
As of iOS 7 beta 5, Run Loop's answer didn't work for me, but this did:
for(UIView *subView in [searchBar subviews]) {
if([subView conformsToProtocol:#protocol(UITextInputTraits)]) {
[(UITextField *)subView setReturnKeyType: UIReturnKeyDone];
} else {
for(UIView *subSubView in [subView subviews]) {
if([subSubView conformsToProtocol:#protocol(UITextInputTraits)]) {
[(UITextField *)subSubView setReturnKeyType: UIReturnKeyDone];
}
}
}
}
One more useful hint, to the Run Loop code (in "#try") section.
This enabled "Done" button when text field is empty:
UITextField *tf = (UITextField *)searchBarSubview;
tf.enablesReturnKeyAutomatically = NO;
For Swift to change return key of UISearchBar
searchBar.returnKeyType = UIReturnKeyType.done
enum available are as below
public enum UIReturnKeyType : Int {
case default
case go
case google
case join
case next
case route
case search
case send
case yahoo
case done
case emergencyCall
#available(iOS 9.0, *)
case continue
}
Just a reminder! If you searchBar stays as first responder, after you change your returnKeyType, you need to dismiss your keyboard and pop it up again to see the changes.
search.resignFirstResponder()
searchBar.returnKeyType = UIReturnKeyType.Done
search.becomeFirstResponder()
As it is a protocol with optional methods, you should test each method separately instead of try-catching.
for (UIView *searchBarSubview in searchBar.subviews)
{
if ([searchBarSubview conformsToProtocol:#protocol(UITextInputTraits)])
{
// keyboard appearance
if ([searchBarSubview respondsToSelector:#selector(setKeyboardAppearance:)])
[(id<UITextInputTraits>)searchBarSubview setKeyboardAppearance:UIKeyboardAppearanceAlert];
// return key
if ([searchBarSubview respondsToSelector:#selector(setReturnKeyType:)])
[(id<UITextInputTraits>)searchBarSubview setReturnKeyType:UIReturnKeyDone];
// return key disabled when empty text
if ([searchBarSubview respondsToSelector:#selector(setEnablesReturnKeyAutomatically:)])
[(id<UITextInputTraits>)searchBarSubview setEnablesReturnKeyAutomatically:NO];
// breaking the loop when we are done
break;
}
}
This will work for iOS <= 6. For iOS >= 7, you need to loop in searchBar.subviews[0].subviews.
Since the Alert-style keyboards are semi-transparent, I can see my view behind it. It doesn't look very good since I have multiple elements behind the keyboard that makes it hard for the keys to stand out. I wanted an all-black keyboard.
So I animated a black UIImageView into position behind the keyboard when text is edited. This gives the appearance of an all-black keyboard.
- (void)textFieldDidBeginEditing:(UITextField *)textField {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.25];
blackBoxForKeyboard.frame = CGRectMake(0, 377, 320, 216);
[UIView commitAnimations];
}
I tried all the solutions shown here, and none of them worked for my UISearchBar (xcode5 compiling for iOS7). I ended up with this recursive function which worked for me:
- (void)fixSearchBarKeyboard:(UIView*)searchBarOrSubView {
if([searchBarOrSubView conformsToProtocol:#protocol(UITextInputTraits)]) {
if ([searchBarOrSubView respondsToSelector:#selector(setKeyboardAppearance:)])
[(id<UITextInputTraits>)searchBarOrSubView setKeyboardAppearance:UIKeyboardAppearanceAlert];
if ([searchBarOrSubView respondsToSelector:#selector(setReturnKeyType:)])
[(id<UITextInputTraits>)searchBarOrSubView setReturnKeyType:UIReturnKeyDone];
if ([searchBarOrSubView respondsToSelector:#selector(setEnablesReturnKeyAutomatically:)])
[(id<UITextInputTraits>)searchBarOrSubView setEnablesReturnKeyAutomatically:NO];
}
for(UIView *subView in [searchBarOrSubView subviews]) {
[self fixSearchBarKeyboard:subView];
}
}
I then called it like so:
_searchBar = [[UISearchBar alloc] init];
[self fixSearchBarKeyboard:_searchBar];
Just for covering all the iOS versions:
NSArray *subviews = [[[UIDevice currentDevice] systemVersion] floatValue] < 7 ? _searchBar.subviews : _searchBar.subviews[0].subviews;
for (UIView *subview in subviews)
{
if ([subview conformsToProtocol:#protocol(UITextInputTraits)])
{
UITextField *textField = (UITextField *)subview;
[textField setKeyboardAppearance: UIKeyboardAppearanceAlert];
textField.returnKeyType = UIReturnKeyDone;
break;
}
}
