i want to know how to set the alignment of delegate message of alert view. anyone has solution, plz reply with some code.
This is just a slightly simplified version of the previous answer but I like to keep things simple. :)
for (UIView *view in alert.subviews) {
if([[view class] isSubclassOfClass:[UILabel class]]) {
((UILabel*)view).textAlignment = NSTextAlignmentLeft;
}
}
You need to get alertView's subViews. Iterate through the array of subview's, it will be having one item of type UILable. Get that UILabel from subview array and for that you can set textAlignment property.
NSArray *subViewArray = alertView.subviews;
for(int x=0;x<[subViewArray count];x++){
if([[[subViewArray objectAtIndex:x] class] isSubclassOfClass:[UILabel class]])
{
UILabel *label = [subViewArray objectAtIndex:x];
label.textAlignment = UITextAlignmentCenter;
}
}
the code below is not work on iOS7, only before iOS7.
for (UIView *view in alert.subviews) {
if([[view class] isSubclassOfClass:[UILabel class]]) {
((UILabel*)view).textAlignment = NSTextAlignmentLeft;
}
}
the question Align message in UIAlertView to left in iOS 7 solve this problem.

In iOS 7 UISearchbar placeholder center-aligned and overlay the bookmarks button until search bar doesn't selected:
When it selected, it looks as expected:

This solution is just adding new UILable view and hide the existing placeholder to give the real feel of searchBar.Again redisplay the actual placeholder when search Bar became active.
This may be a temporary hack to fix that UI issue in IOS7.
OLD SOLUTION:
[searchField setValue:[NSNumber numberWithBool:YES] forKeyPath:#"_placeholderLabel.adjustsFontSizeToFitWidth"];
will not work in ios7 because the size of lable used for disaplay the content is enough to show the text, the problem is the label width bug of ios7. it fails to re-size the label width.
there is little bit hack to fix this.
UITextField *searchField = [searchBar valueForKey:#"_searchField"];
UILabel *lable=[searchBar valueForKey:#"_placeholderLabel"];
lable.font=[UIFont fontWithName:lable.font.fontName size:10.0];
calculate the font-size based upon the search bar width of your own. I also tried to change the width of particular label but it never work.
-(void)viewDidAppear:(BOOL)animated{
self.searchBar.placeholder=#"woord hier invoeren";
}
-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar{
self.searchBar.placeholder=#"woord hier invoeren.......";
}
I'm not here to give you a general solution but if you have a placeHolder to add, the dumbest and easy way to do it is by truncating the placeHolder yourself, so instead of
searchBar.placeholder = #"woord hier invoeren";
let it be
searchBar.placeholder = #"woord hier invo...";
i tried to mess with the private methods of apple but with no luck:
the searchBar subviews are :
-UISearchBarBackground.
-UISearchBarTextField.
leave the UISearchBarBackground aside
the subviews of the UISearchBarTextField instance are :
-_UISearchBarSearchFieldBackgroundView.
-UIImageView.
-UISearchBarTextFieldLabel.
what i went for is trying to mess with the rect (i emphasis on the word mess as these are private methods) of the UISearchBarTextFieldLabel coz i'm pretty sure that its frame ain't rendered right when the searchBar button is shown (bookmark), if you choose searchBar.showsBookmarkButton = NO; the placeHolder text will be truncated as expected.
It's up to you, save yourself sometime and go with the dumb solution but that gets things done, or delve even further.
keep up the good work.
I'm Using iCarousel to show my Custom UIView in CoverFlow Mode but when i run my app it is show up but nothing inside it , it is like not the view i add ???
so can u help me ???
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
CustomView *temp;
if (view == nil)
{
//don't do anything specific to the index within
//this `if (view == nil) {...}` statement because the view will be
//recycled and used with other index values later
view = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 315.0f, 350.0f)] autorelease];
temp=[[CustomView alloc] initWithFrame:view.bounds];
temp.backgroundColor=[UIColor redColor];
view.contentMode = UIViewContentModeCenter;
temp.tag=1;
[view addSubview:temp];
}
else
{
//get a reference to the label in the recycled view
temp = (CustomView *)[view viewWithTag:1];
}
//set item label
//remember to always set any properties of your carousel item
//views outside of the `if (view == nil) {...}` check otherwise
//you'll get weird issues with carousel item content appearing
//in the wrong place in the carousel
//label.text = [[items objectAtIndex:index] stringValue];
return view;
}
Some thinks you could check :
Did you implement iCarouselDelegate and iCarouselDataSource ?
Did you set the carousel's delegates
ex. myCarousel.delegate = self; myCarousel.dataSource = self;
Did you add the carousel's view to the view stack
ex. [myView.view addSubview:myCarousel];
You should also implement the following delegate method
(NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
I have a View Controller with 3 subviews inside the self.view.
I'm trying to slide between them and it's not working.
Here is my code:
- (void)viewDidLoad
{
UISwipeGestureRecognizer *swipeGestureRecognizerLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(didSwipe:)];
swipeGestureRecognizerLeft.direction = UISwipeGestureRecognizerDirectionLeft;
for (UIView *subview in self.view.subviews)
{
if([subview isKindOfClass:[UIView class]] && !([subview isKindOfClass:[UIImageView class]]))
{
[subview addGestureRecognizer:swipeGestureRecognizerLeft];
NSLog(#"Load 2");
}
}
}
-(void) didSwipe:(UISwipeGestureRecognizer *) swipeRecognizer {
NSLog(#"Load swipe");
if (swipeRecognizer.direction==UISwipeGestureRecognizerDirectionLeft)
{
NSLog(#"swipe Left");
[self SlideToLeft];
}
}
I really see that "Load 2" is being printed 3 times but when I try to slide it's not working.
Thank you
Are you using a UIScrollView here? That could be the problem.
I think you can just use the standard UIScrollView delegate methods in this situation:
- (void) scrollViewDidScroll: (UIScrollView *) sender
{
NSLog(#"Scrolled!");
}
Otherwise these guys here, here and here had some trouble too, maybe the answers there could help you.
If you're not using a UIScrollView here? I should use one, why not? 3 Subviews and swiping to the next one sounds just like a nice UIScrollView example (use paging).
Good Luck!
I am using a UISearchBar to match text input against entries in a database and display the matched results to the user in a UITableView, as they type.
All is well, however, I cannot find a way to alter the return key type of the search bar's keyboard. By default it replaces the standard return key with a Search button. Because I am doing a live search as the user types, I do not need this button and having it there and inactive has raised some usability issues.
Attempted solutions
I can set a keyboard with the setKeyboard:UIKeyboardType method, however this doesn't seem to override the default setting of replacing the return key (on the standard keyboard) with a Search key and it does not allow access to change this return key.
I have thought about using a UITextField, giving me access to the returnKeyType property through the UITextInputTraits protocol. My problem with this however is that I am implementing the UISearchBarDelegate method searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText, which I would lose with the UITextField.
Is there a way that I can keep the functionality of the search bar's delegate methods, whilst having legitimate access to the keyboard's return key?
In fact, almost the exact screen I am implementing is found in Apple's Clock application
Screenshot:
So any help on a clean solution would be much appreciated. Note the return key on the bottom right instead of the default Search button'.
Slightly different in iOS 7 compared to the answer of #sudip.
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;
}
}
}
I tried all of these solutions without luck until I realized that in IOS8, you can just set searchBar.returnKey = .Done or whatever UIReturnKeyType you like. Sigh.
Try this:
for(UIView *subView in searchBar.subviews) {
if([subView conformsToProtocol:#protocol(UITextInputTraits)]) {
[(UITextField *)subView setKeyboardAppearance: UIKeyboardAppearanceAlert];
}
}
If you want to dismiss the return key (i.e., make it do nothing), set the "returnKeyType" property on the UITextField subview to "UIReturnKeyDone" along with "keyboardAppearence".
I had to add some lines to Neo's answer. Here is my code to add a "Done" button for UISearchbar :
for(UIView *subView in sb_manSearch.subviews) {
if([subView conformsToProtocol:#protocol(UITextInputTraits)]) {
UITextField *t = (UITextField *)subView;
[t setKeyboardAppearance: UIKeyboardAppearanceAlert];
t.returnKeyType = UIReturnKeyDone;
t.delegate = self;
break;
}
}
To change Search into Done text.
Use below code.
youtSearchBar.returnKeyType = .done
you can do it by :
- (void)viewDidLoad
{
// Adding observer that will tell you keyboard is appeared.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardDidShow:)
name:UIKeyboardDidShowNotification object:nil];
[super viewDidLoad];
}
- (void)keyboardDidShow:(NSNotification *)note
{
keyboardTest = [self getKeyboard];
[keyboardTest setReturnKeyEnabled: YES];
}
- (id) getKeyboard // Method that returns appeared keyboard's reference
{
id keyboardView;
// locate keyboard view
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for(int i=0; i<[tempWindow.subviews count]; i++)
{
keyboard = [tempWindow.subviews objectAtIndex:i];
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2)
{
if([[keyboard description] hasPrefix:#"<UIPeripheralHost"] == YES)
{
keyboard = [[keyboard subviews] objectAtIndex:0];
keyboardView = keyboard ;
}
}
else
{
if([[keyboard description] hasPrefix:#"<UIKeyboard"] == YES)
keyboardView = keyboard ;
}
}
return keyboardView ;
}
UPDATE : From iOS 7 onwards, the accepted answer will not work, below version will the work on iOS 7 onwards.
UIView *subViews = [[_searchBar subviews] firstObject];
for(UIView *subView in [subViews subviews]) {
if([subView conformsToProtocol:#protocol(UITextInputTraits)]) {
[(UITextField *)subView setEnablesReturnKeyAutomatically:NO];
}
}
for (UIView *subView in view.subviews) {
if ([subView isKindOfClass:[UITextField class]])
{
UITextField *txt = (UITextField *)subView;
#try {
[txt setReturnKeyType:UIReturnKeyDone];
[txt setKeyboardAppearance:UIKeyboardAppearanceAlert];
}
#catch (NSException * e) {
// ignore exception
}
}
}
I just found the simplest wait to hack this, just put a blank when beginning editing search field
-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar{
//Add a blank character to hack search button enable
searchBar.text = #" ";}
I have one class in which i have two method _addView() and _removeView().
And these method i am using in another class for adding view and removing view but its not working.If i am using in the same then its working.
For Remove-
- (id)deleteBoxAtIndex:(int)boxIndex{
for (int i = 0; i < [[self subviews] count]; i++ ) {
[[[self subviews] objectAtIndex:boxIndex] removeFromSuperview];
}
return self;
}
Then how i count the subviews in that class or remove from that class.
You correct in trying to use [self.subviews count] to count the number of subviews, but there is an elegant way to remove all subviews from a view in Objective-C. Try this:
[self.subviews makeObjectsPerformSelector:#selector(removeFromSuperView)];
You should pass a pointer to the UIView instance (the one that has got the subviews) to the other object so that you can call:
myView.subviews
I don't know if this could work for you:
- (id)deleteBoxAtIndex:(int)boxIndex fromView:(UIView*)view {
for (int i = 0; i < [[view subviews] count]; i++ ) {
[[[view subviews] objectAtIndex:boxIndex] removeFromSuperview];
}
return self;
}
If you give more detail about the relationship between the two classes you mention (basically, the names and how one interact with the other), I could give you more hints.
Your problem not in retrieving the count but in fact that your relay on a count that changes dynamically inside of your for loop logic execution. Do cleanup of subviews in the following way:
while([[self subviews] count] > 0) {
UIView *view = [[self subviews] objectAtIndex:0];
[view removeFromSuperview];
}
You can use the superview property:
[[self superview] subviews]
to do the similar loop you are doing right row. However I'd strongly encourage you to use
[[self superview] viewWithTag:boxIndex]
instead of objectAtIndex: method
Just do a loop of all subViews u want to remove:
for (UIView *subs in [self.view subviews]){
[subs removeFromSuperview];
}
