Backbarbuttonitem letterpress effect - iphone

How can I recreate the letterpress-like effect applied to the backbarbuttonitem in the notes app in ios 7? I tried the following:
NSShadow *textShadow = [[NSShadow alloc] init];
textShadow.shadowOffset = CGSizeMake(0.0, -1.0);
textShadow.shadowColor = [UIColor blackColor];
NSAttributedString *attributedTitle = [[NSAttributedString alloc] initWithString:#"Back" attributes:#{NSForegroundColorAttributeName : [UIColor orangeColor], NSShadowAttributeName : textShadow}];
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:attributedTitle style:UIBarButtonItemStylePlain target:nil action:nil];
But it says I can't use NSAttributedString in place of an NSString.

For iOS 5 and above, you can use the UIAppearance functionality to change the Text Color, Font, Tint Color etc of multiple UI Components like UITabBar, UIBarButton, etc.
for UIBarButtonItem, check the below two options.
Option1: For ANY UIBarButtonItem:
NSDictionary *aButtonAttribute = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor darkGrayColor], UITextAttributeTextColor,
[UIColor whiteColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset, nil];
[[UIBarButtonItem appearance] setTitleTextAttributes:aButtonAttribute forState:UIControlStateNormal];
Option 2: For UIBarButtonItem of a UINavigationBar ONLY:
NSDictionary *aButtonAttribute = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor darkGrayColor], UITextAttributeTextColor,
[UIColor whiteColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset, nil];
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:aButtonAttribute forState: UIControlStateNormal];
NOTE: You can add these lines (either of the 2 options) in the .m file of AppDelegate..

Changing segmented control segment background not working

Ive added a segmented control to the header of a uitableview. this works fine. but for some reason i cannot make the segmented buttons (or at least just the first button) have a red background color. it just loads with the default silver.
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
UIView* NEWview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
NEWview.backgroundColor = [UIColor colorWithRed:78.0/255.0f green:88.0/255.0f blue:74.0/255.0f alpha:1.0];
NSArray *itemArray = [NSArray arrayWithObjects: #"Organisations", #"Events", nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(15, 5, 290, 30);
segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
segmentedControl.selectedSegmentIndex = 1;
UIColor *newSelectedTintColor = [UIColor redColor];
[[[segmentedControl subviews] objectAtIndex:0] setTintColor:newSelectedTintColor];
[NEWview addSubview:segmentedControl];
return NEWview;
}
Any Ideas? Thanks in advance for any help..
Tint color for segmentedcontrol works only if segmented control is of bar style.
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.tintColor=[UIColor redColor];
Refer this link to changed background color of selected segment
U can also do is set title color slected and not selected like this:
NSDictionary *normalAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:#"Arial" size:20.0],UITextAttributeFont,
[UIColor colorWithRed:75.0/255.0 green:75.0/255.0 blue:75.0/255.0 alpha:1.0], UITextAttributeTextColor,
[UIColor clearColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
nil];//[NSDictionary dictionaryWithObject: [UIColor redColor]forKey:UITextAttributeTextColor];
[segmentCtrl setTitleTextAttributes:normalAttributes forState:UIControlStateNormal];
NSDictionary *selectedAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:#"Arial" size:20.0],UITextAttributeFont,
[UIColor redColor], UITextAttributeTextColor,
[UIColor clearColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
nil] ;//[NSDictionary dictionaryWithObject: [UIColor redColor]forKey:UITextAttributeTextColor];
[segmentCtrl setTitleTextAttributes:selectedAttributes forState:UIControlStateSelected];

UIBarButtonItem appearance iOS5 font

I am using a little chunk of code like below to change the text attributes of my nav bar title app wide and it works great.
[[UINavigationBar appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIColor grayColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Cochin-BoldItalic" size:0.0], UITextAttributeFont,
nil]];
But I want to be able to just as easily do this for UIBarButtonItem text as well but I can't figure it out as it doesn't share the same or similar methods it appears.
Edit
Tried this code, not making any changes to text:
[[UIBarItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIColor grayColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Cochin-BoldItalic" size:12.0], UITextAttributeFont,
nil]
forState:UIControlStateNormal];
You want to use the - (void)setTitleTextAttributes:(NSDictionary *)attributes forState:(UIControlState)state method of UIBarItem (UIBarButtonItem inherits from UIBarItem).
Check out the docs for more details: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIBarItem_Class/Reference/Reference.html#//apple_ref/occ/cl/UIBarItem
Try this:
//Suppose you have initialized barButton elsewhere`
[barButton setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIColor grayColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Cochin-BoldItalic" size:12.0], UITextAttributeFont,
nil]
forState:UIControlStateNormal];
This seems to work on iOS 7.1:
[[UIBarButtonItem appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName:[UIColor whiteColor],
NSFontAttributeName:[UIFont fontWithName:#"Resamitz" size:16.0]}
forState:UIControlStateNormal];

Navigation Bar Back Button, text not center alligined

I am customizing the back button in the navigation bar using appearance proxy, also setting image and text attributes. Everything works fine but the text in back button is not center aligned.
Here is my code.
UIBarButtonItem *backButton = [[[UIBarButtonItem alloc] initWithTitle:title style:UIBarButtonItemStyleBordered target:nil action:nil] autorelease];
UIImage *buttonBack32 = [[UIImage imageNamed:#"NavigationBackButton"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 5)];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:buttonBack32 forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],
UITextAttributeTextColor,
[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],
UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"xxx" size:16.0],
UITextAttributeFont,
nil]
forState:UIControlStateNormal];
self.navigationItem.backBarButtonItem = backButton;
If I set the font size "0.0" then text becomes too small in size and still not centered aligned.
Thanks in advance for any help.
You can use the setTitlePositionAdjustment:forBarMetrics: method to set the title offset as required. For example:
[[UIBarButtonItem appearance] setTitlePositionAdjustment:UIOffsetMake(0.0f, 5.0f) forBarMetrics:UIBarMetricsDefault];
To adjust the text up I had to use this:
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -1.5) forBarMetrics:UIBarMetricsDefault];
You can use this :
UIView* leftContainer = [[UIView alloc] initWithFrame:CGRectMake(0.0, 4.0, 70.0, 44.0)];
UIImage *profileImg = [UIImage imageNamed:#"account-btn.png"];
UIButton *profilebutton = [UIButton buttonWithType:UIButtonTypeCustom];
profilebutton.frame = CGRectMake(0.0, 7.0, 70.0, 30.0 );
[profilebutton setImage:profileImg forState:UIControlStateNormal];
[profilebutton addTarget:self action:#selector(profileBtnClicked) forControlEvents:UIControlEventTouchUpInside];
[leftContainer addSubview:profilebutton];
UIBarButtonItem* item = [[UIBarButtonItem alloc] initWithCustomView:leftContainer];
self.navigationItem.leftBarButtonItem = item;
[leftContainer release];
[item release];

Change UILabel Text inside UISegmentedControll according to its status

Is there any way to use UIAppearance to change the text color of a selected segment in UISegmented Controller and let other segments have same Color ?
NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:220.0/255.0 green:104.0/255.0 blue:1.0/255.0 alpha:1.0], UITextAttributeTextColor,
[UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
[UIFont systemFontOfSize:14], UITextAttributeFont,
nil];
[[UISegmentedControl appearance] setTitleTextAttributes:attributesDictionary forState:UIControlStateSelected];

How to remove gradient / drop shadow for UITabbaritem in iOS 5

thanks for reading
-(void)UIAppearances
{
//set the background of tab bar

}
else {
//iOS 4.whatever and below
[self.tabBarController.tabBar insertSubview:imageView atIndex:0];
}
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque animated:NO];
}
UITabBar can either take an image and use its alpha channel (opacity) to build the selected/unselected images or take two processed images to use as is.
You'll have to provide the images yourself to the UITabBarItem with setFinishedSelectedImage:withFinishedUnselectedImage:. There's no other way to affect the processing it does to the images besides changing the color of the gradient with UITabBar's selectedImageTintColor appearance property.
