I want my search bar to look like this:
this is how i created the search bar:
search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 308, 27)];
search.delegate = self;
search.center = CGPointMake(self.frame.size.width/2, 10 +search.frameHeight/2);
search.placeholder = NSLocalizedString(#"search foods you like or dislike", nil);
search.backgroundImage = nil;
search.backgroundColor = [UIColor clearColor];
but this is what i get :
what am i doing wrong ? how do i get rid of the extra grey edges on the sides of the textField ?
You can achieve that with the following code:
search.barTintColor = [UIColor clearColor];

I am using the below code to display a toolbar as a accessory view for a picker view. I want to customise the tool bar colour. I am not sure whats wrong in this below code. Is there a better way to achieve this
UIToolbar* state_close = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 50)];
state_close.translucent =NO; //.barStyle = UIBarStyleDefault;
state_close.barTintColor = [UIColor colorWithRed:0.94 green:0.94 blue:0.94 alpha:1.0];
[state_close sizeToFit];
Thanks in Advance
Objective - C
Your code is working fine.
try to change y position of the state_close like below
UIToolbar *state_close = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 200, self.view.frame.size.width, 50)];
state_close.barTintColor = [UIColor blackColor];
state_close.alpha = 1.0;
[state_close sizeToFit];
[self.view addSubview:state_close];
if you want to set y = 0 then hide navigationBar.
[self.navigationController.navigationBar setHidden:true];
I am setting a label inside of an empty table view's background view, which is placing the label in the middle of the tableview.
I'd like to move that label up a bit, so it's near the top of the table view, however the code below isn't working:
UILabel *messageLbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.tableView.bounds.size.width, 20)];
messageLbl.text = #"NO REGISTRATIONS FOUND";
messageLbl.font = [UIFont fontWithName:#"Sansation-Bold" size:20.0f];
messageLbl.textColor = [UIColor lightGrayColor];
messageLbl.textAlignment = NSTextAlignmentCenter;
[messageLbl sizeToFit];
//set back to label view
self.tableView.backgroundView = messageLbl;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.backgroundView.frame = CGRectMake(0, 0, self.tableView.bounds.size.width, 100);
Another easy solution is to add your messageLbl to tableHeaderView:
UILabel *messageLbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.tableView.bounds.size.width, 50)];
messageLbl.text = #"\n\n NO REGISTRATIONS FOUND";
messageLbl.font = [UIFont fontWithName:#"Sansation-Bold" size:20.0f];
messageLbl.textColor = [UIColor lightGrayColor];
messageLbl.textAlignment = NSTextAlignmentCenter;
messageLbl.numberOfLines = 0;
[messageLbl sizeToFit];
//set back to label view
self.tableView.tableHeaderView = messageLbl;
Quick solution is just by adding \n at the end the of text and set no of lines to 0. Try this
messageLbl.numberOfLines = 0;
messageLbl.text = #"NO REGISTRATIONS FOUND\n\n\n\n";
Looks like you were hiding the Y axis behind Navigation bar
try it by setting some Y axis height & Don't forget to add SubView
UILabel *messageLbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 100, self.tableView.bounds.size.width, 20)];
messageLbl.text = #"NO REGISTRATIONS FOUND";
messageLbl.font = [UIFont fontWithName:#"Sansation-Bold" size:20.0f];
messageLbl.textColor = [UIColor lightGrayColor];
messageLbl.textAlignment = NSTextAlignmentCenter;
[messageLbl sizeToFit];
//set back to label view
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
[self.view addSubview: messageLbl];
I have a searchbar embedded in a navigationbar. I'm able to change background color, but for the life of me cannot change text color. I have the following code in my viewdidload. What is missing to get the text to change?
if(!itemSearchBar)
{
itemSearchBar = [[UISearchBar alloc] init];
[itemSearchBar setFrame:CGRectMake(0, 0, self.view.frame.size.width, 55)];
itemSearchBar.placeholder = #"What are you looking for?";
itemSearchBar.delegate = self;
UITextField *txfSearchField = [itemSearchBar valueForKey:#"_searchField"];
txfSearchField.backgroundColor = [UIColor colorWithRed:130/255.0 green:58/255.0 blue:23/255.0 alpha:1.0];
UISearchDisplayController *searchCon = [[UISearchDisplayController alloc]
initWithSearchBar:itemSearchBar
contentsController:self ];
[searchCon setActive:NO animated:YES];
self.searchDisplayController = searchCon;
self.searchDisplayController.delegate = self;
self.searchDisplayController.searchResultsDataSource = self;
self.searchDisplayController.searchResultsDelegate = self;
self.searchDisplayController.displaysSearchBarInNavigationBar=YES;
I've read that the following should work but doesn't:
[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setTextColor:[UIColor blueColor]];
I've also tried:
itemSearchBar.tintColor = [UIColor redColor];
txfSearchField.textColor = [UIColor redColor];
Any suggestions???
I think you are looking at the color of placeholder text and not typing anything in the textfield. Otherwise, your code seems correct. The method
txfSearchField.textColor = [UIColor redColor]
must work. Type anything in the field and you will see red color.
On iOS7.0.3 - 7.0.6, my searchBar colour is Gold/yellow colour like this:
But on iOS 7.1, colour becomes like this:
I set
searchBar.tintColor = [UIColor clearColor];
searchBar.backgroundColor = goldColor;
searchBar.tintColor = [UIColor blackColor];
I've tried so many ways and all are failed. Can anyone figure out what changes in iOS 7.1?
============== My fix ===============
I fix this problem by covering a view on searchBar and add the search text filed as subview on this new view.
I need point out that the gold status bar is a subView of searchBar, and it's frame is CGRectMake(0, -20, 320, 20) and it's background colour is gold.
At first, I set this:
_searchBar.translucent = YES;
_searchBar.scopeBarBackgroundImage = [self imageWithColor:UWGold];
and looks like this:
Then, I expand the view cover the status bar, I changed the view's frame.size.height + searchBar's height, then use this line:
UITextField *textSearchField = [_searchBar valueForKey:#"_searchField"];
to get the textSearchField, then add this textSearchField to the cover view.
At last, the searchBar is exactly like when on iOS 7.0
Not a good way, I need figure out what changes on iOS 7.1 and use a right way to implement this.
Try this:
if(IOS_7)
{
self.searchBar.searchBarStyle = UISearchBarStyleMinimal;
self.searchBar.backgroundImage = [UIImage imageWithColor:[UIColor redColor] cornerRadius:5.0f];
}
Hopefully this will help you.
None of the above answers worked for me on iOS 7/8. Here's some setup code that did the trick:
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.frame), 44)];
searchBar.scopeButtonTitles = #[#"Scope1", #"Scope2"];
searchBar.selectedScopeButtonIndex = 0;
searchBar.backgroundColor = [UIColor clearColor];
searchBar.barTintColor = [UIColor clearColor];
searchBar.translucent = YES; // SUPER IMPORTANT, REMOVING THIS MESSED UP THE SCOPE BAR
// ONLY USE IMAGES, NOT BACKGROUND COLORS
UIImage *searchBarBackgroundImage = [[UIImage imageNamed:#"SearchBarBackgroundImage"];
UIImage *scopeBarBackgroundImage = [[UIImage imageNamed:#"ScopeBarBackgroundImage"];
[searchBar setBackgroundImage:searchBarBackgroundImage
forBarPosition:UIBarPositionAny
barMetrics:UIBarMetricsDefault];
searchBar.scopeBarBackgroundImage = scopeBarBackgroundImage;
searchBar.tintColor = [UIColor whiteColor];
I used next approach for changing backgroundColor of searchBar
1.As suggested by #Ben Jackson - set BackgroundImage
[self.searchBar setBackgroundImage:[self imageWithColor:[UIColor blueColor]] forBarPosition:UIBarPositionAny
barMetrics:UIBarMetricsDefault];
2.Change textField to what u need according to design
NSArray *searchBarSubViews = [[self.searchBar.subviews objectAtIndex:0] subviews];
for( int i = 0; i < searchBarSubViews.count; i++) {
if([[searchBarSubViews objectAtIndex:i] isKindOfClass:[UITextField class]]) {
UITextField *searchTextField = (UITextField *)[searchBarSubViews objectAtIndex:i];
[searchTextField setTintColor:[UIColor blueColor]];
searchTextField.placeholder = #"Search";
searchTextField.backgroundColor = [UIColor whiteColor];
searchTextField.layer.borderColor = [UIColor blueColor].CGColor;
searchTextField.layer.borderWidth = 1.0f;
searchTextField.layer.cornerRadius = 8.0f;
searchTextField.leftViewMode = UITextFieldViewModeNever;
}
}

Result:
I'm using a UILabel for the titleView of a navigation bar (I'm making simple in-app web browser). It works fine, except that when I present a modal view controller, the titleView shifts from the center of the navbar to the far left (underneath the back button). I've tested in 3.0 and up. Here is relevant code:
- (void)viewDidLoad {
[super viewDidLoad];
// Title view label
CGRect labelFrame = CGRectMake(0.0, 0.0, 120.0, 36.0);
UILabel *label = [[[UILabel alloc] initWithFrame:labelFrame] autorelease];
label.font = [UIFont boldSystemFontOfSize:14];
label.numberOfLines = 2;
label.backgroundColor = [UIColor clearColor];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.shadowColor = [UIColor blackColor];
label.shadowOffset = CGSizeMake(0.0, -1.0);
label.lineBreakMode = UILineBreakModeMiddleTruncation;
self.navigationItem.titleView = label;
}
-(void)displayComposerSheet:(NSString*)mailto
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[self presentModalViewController:picker animated:YES];
[picker release];
}

Any idea why this is happening? Thanks.
I looked into the problem with some hit and try and found the following facts:
If the UINavigationBar doesn't have the rightBarButtonItem, the titleView shifts towards the right by ~30pts.
It could be reproduced for leftBarButtonItem. But I haven't tried.
In a scenario where the a default UINavigationBar's (with no changes to rightBarButtonItem defaults) titleView is set. And then a new UIView is pushed to the navigation stack which HAS a rightBarButtonItem. Now, if this view is popped [with back button], the navigation bar will remove the rightBarButtonItem. And this will account for the weird offset that shifts the titleView towards a side.
How I fixed the problem was like this:
self.navigationItem.titleView = myCustomTitleView;
// Fake right button to align titleView properly.
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:[[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 1)]];
// Width equivalent to system default Done button's (which appears on pushed view in my case).
rightBarButtonItem.enabled = NO;
self.navigationItem.rightBarButtonItem = rightBarButtonItem;
Everything is sweet now. yummmm.
Thanks to DougW for pointing me in right direction. Here's the best hack I found. Basically I retain the UILabel as a class property. Before presenting modal view I unset the titleView, and then reset it immediately after. When the modal view is dismissed I unset then reset the titleView. To the user none of this is visibly notable.
-(void)displayComposerSheet:(NSString*)mailto
{
self.navigationItem.titleView = nil;
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
picker.navigationBar.tintColor = [APPDELEGATE getNavTintColor];
[picker setToRecipients:[NSArray arrayWithObject:mailto]];
[self presentModalViewController:picker animated:YES];
[picker release];
self.navigationItem.titleView = titlelabel;
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
self.navigationItem.titleView = nil;
self.navigationItem.titleView = titlelabel;
[self dismissModalViewControllerAnimated:YES];
}
Does it animate? It may be animating the title view as though it's transitioning to a new view. I don't see anything wrong with your code as written.
I would suggest in your displayComposerSheet, you just unset the titleView, or animate the alpha of the titleView to 0.0. Then, animate it back to 1.0 when you dismiss the modal view controller. Not ideal, but it may look better that way.
Frankly, the whole UINavigation system is crap. We went ahead and re-wrote it ground up because of bizarre issues like these.
The only problem is your frame size. so u have to change it.
Try this one.
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 36.0)];
label.font = [UIFont boldSystemFontOfSize:14];
label.numberOfLines = 2;
label.backgroundColor = [UIColor clearColor];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.shadowColor = [UIColor blackColor];
label.shadowOffset = CGSizeMake(0.0, -1.0);
label.lineBreakMode = UILineBreakModeMiddleTruncation;
label.text=#"Stack Overflow";
self.navigationItem.titleView = label;
You can try move the code in viewDidAppear:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
// You code to customize title view
self.navigationItem.titleView = logoImage;
}
It works for me.
If you change the width size to be small like 100 points or smaller instead of 120 you set, this problem may go away. Setting width of the label smaller worked for me.
UIView *view= [[UIView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
[view setUserInteractionEnabled:NO];
view.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:#"logo_small.png"]];
UIBarButtonItem *barButton=[[UIBarButtonItem alloc]initWithCustomView:view ];
self.navigationItem.leftBarButtonItem = barButton;
