I want a photo viewer in my iphone app and I liked the Three20 photo viewer. I found it somehow hard to integrate it in my own app where I have my typical UINavigationViewController. So far I succeeded in doing the following:
TTURLMap *map = [[[TTURLMap alloc] init] autorelease];
[map from:#"tt://appPhotos" toSharedViewController:[PhotoViewController class]];
[self.navigationController pushViewController:[map objectForURL:#"tt://appPhotos"] animated:YES];
The only problem is that wenn I click back to my original view, its navigation bar keeps the style of the photo viewer (transperant and shows the view under it).
How can I get back my original navigation bar?
My experience: I once used three20's PhotoViewer and every time I went back from the PhotoViewer to my other view. The system status bar remained black and transparent (while it should be with default style). I solved it by manually and programmatically changing the status bar style every time when the back action was triggered.
Yes, this is a bit of an issue for sure. A good solution, as #diwup says, is to implement a manual fix. I tend to subclass TTPhotoViewer when I need it. Not only does it help with this problem but it also makes it much easier to use I find.
If you decide to subclass, then you should use whatever variation of the following you require:
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
self.navigationController.navigationBar.tintColor = myTintColor;
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
}
However, if you don't want to subclass, you can always put the code into the - [viewWillAppear:] method of any class that comes after the photo viewer.

I have a button in my app to bring up an SLComposeViewController for use with Twitter. When the view is presented it animates in correctly and the disappears. I have found that when it disappears it is sent to the back of the current view and I have no way to bring it back. I have tried manually sending all the views on top to the back in code with no luck. I feel there is something fundamentally wrong with my app for this to happen as this behaviour is seen at any level to the Navigation Controller in the app. Below is a screenshot of the SLComposeViewController being the Navigation Bar in the app, I made the ViewController's view have an Alpha value of 0.0f to illustrate my point:
I really don't know what is going on here and any help will be greatly appreciated. The code I am using to present the SLComposeViewController is pretty standard and I have tested it in another app and works fine:
NSString *message = [NSString stringWithFormat:#"#%#", [twitterInfo objectForKey:#"hashtag"]];
if ([appDelegate isSocialAvailable]) {
// code to tweet with SLComposeViewController
SLComposeViewController *twitter = [[SLComposeViewController alloc] init];
twitter = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[twitter setInitialText:[NSString stringWithFormat: #"%#", message]];
[self presentViewController:twitter animated:YES completion:nil];
}
Thanks for posting this, I had the same thing happen because I was adding a CAShapeLayer to my window for a gradient effect. Your post helped me figure out that this was the problem.
It looks like this is happening is because they are adding their view's layer to the window's sublayers--at index 0 I might add! This is contrary to what you would expect, which is that they would add their view as a subview to the presenting view controller's view.
They must have just thought that people don't add layers to their window and they want to make sure they are not competing with your view stack. Why they would put it into index 0 must only be because someone is in the habit of doing -[CALayer insertLayer:layer atIndex:0] I suppose.
I'm not certain but I am guessing this could be the case with any modal view controller.
The fix is pretty simple:
[viewController presentViewController:facebookViewController
animated:YES
completion:^{
facebookViewController.view.layer.zPosition = 1000;
}];
After a week of tearing my hair out to find a solution to this I have found the offending code in the app, a little trick to round the corners of the whole app, well make it seem like the corners are rounded by adding an image there:
UIImage *bottomOverlayImage = [UIImage imageNamed:#"bottom_overlay.png"];
CALayer *bottomOverlay = [CALayer layer];
bottomOverlay.frame = CGRectMake(0, self.window.frame.size.height - 9, bottomOverlayImage.size.width, bottomOverlayImage.size.height);
bottomOverlay.contents = (id)bottomOverlayImage.CGImage;
bottomOverlay.zPosition = 1;
[self.window.layer addSublayer:bottomOverlay];
If anybody could tell me why this code would mess up the Twitter View that would be really helpful for future reference. This code was placed in the app delegate and run on first load.
I am building a PhoneGap app using Cordova 2.2 for IOS. I am experiencing some bizarre behavior when calling out to a native obj-c plugin I have written to show the MFMessageComposeViewController.
The setup is very simple - I have a tap event attached to a UI element, that when pressed, will make a call to my PhoneGap plugin, pass with it a number and a text message, then show the MFMessageComposeViewController with the parameters pre-populated.
My javascript looks like this:
$(document).bind('deviceready', function(){
$(".theButton").tap(function(){
cordova.exec(function(){}, function() {}, "PhoneGapSms", "SendSms", [db.getItem("profile_sms"), db.getItem("profile_emergency")]);
});
});
And my obj-c code looks like this:
- (void)SendSms:(CDVInvokedUrlCommand*)command
{
CDVInvokedUrlCommand* myCommand = command;
MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
NSString* body = [command.arguments objectAtIndex:0];
NSString* toRecipientsString = [command.arguments objectAtIndex:1];
if(body != nil)
picker.body = body;
if(toRecipientsString != nil)
[picker setRecipients:[ toRecipientsString componentsSeparatedByString:#","]];
picker.messageComposeDelegate = self;
[self.viewController presentModalViewController:picker animated:YES];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[picker release];
}
So, all in all, very simple stuff.
My Problem is this:
When my iPhone is plugged into my Mac and the app is run from XCode, the Message Composer overlay appears great, with my values pre-populated. Image below demonstrating the SMS interface appears fine while plugged into XCode:
When my iPhone is unplugged from my Mac, and the app is run from the spring board, the Overlay slides up, the keyboard begins to slide up, then immediately slides down - making it impossible to type or send the message. This is what it looks like when not attached to the Mac/Xcode - the keyboard begins to slide up then immediately slides down (~ < 1 sec) leaving the following interface:
I can't for the life of me figure out what would cause the keyboard to hide when not running from XCode, but work perfectly well when it is.
Is there any way to 'force' the keyboard to display, or possibly put the whole modalviewcontroller as first responder in some form or fashion?
Any suggestions are appreciated!
Edit:
The keyboard WILL appear again if you click in the contact area
You must add MessageUI.framework to your Xcode project and include a
#import <MessageUI/MessageUI.h> in your header file.
try this code may be its helpful to you..
[self presentModalViewController:picker animated:YES];
//[self becomeFirstResponder];//try picker also instead of self
Also Refer this bellow tutorial and also check demo..

i hope this help you...
I encountered these symptoms with a Sencha Touch 2.2 and Cordova 2.6.0 setup (specifically, iOS 6+ devices).
The issue was with the web framework stealing focus away from the native SMS Composer modal, typically occurring after the first SMS Composer modal had been successfully displayed and closed.
A event.preventDefault() and event.stopPropagation() call once the event had been fired (or event.stopEvent() in Sencha land) resolved this.
Hope this helps,

First: The most likely culprit, without seeing your code, is that your parent (presenting) view controller may have an action in its viewWillDisappear or viewDidDisappear that is affecting who has the "first" responder. These methods get called when presenting a view controller modally. It may be behaving differently on the simulator than the device due to timing - often really close timing conditions are different on the ARM device and the i386 processor.
Second: Does anywhere in your app register for the UIKeyboardWillShowNotification or the UIKeyboardDidShowNotification? If so, put breakpoints in the methods that are called as a result - it's possible some other controller in your view hierarchy is interfering with this one.
To answer your question...
Is there any way to 'force' the keyboard to display, or possibly put the whole modalviewcontroller as first responder in some form or fashion?
No to both. The only way to make the keyboard display is to call the becomeFirstResponder method of the input view. Since Apple doesn't expose the text view, you cannot send it messages. Setting the modalViewController as first responder would be setting the wrong object.
I found the same type of issue But Not Sure it will Solve your problem or not Just Have a Look on the Following Links :
1. http://community.phonegap.com/nitobi/topics/keyboard_is_not_triggerd_in_my_ios_build

I'm creating an app, that is in some point turning photo library on. The problem is that status bar is black transparent in photo library while i want a default application one (solid white). Is there any way to change it..?
I would add, that i tried regarding to this: iOS SDK - How to get the status bar back when using UIImagePickerController? method:
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES];
}
works only for camera for me, not photo library. Of course i tried with default style too.
UPDATE: i found out a way to change navigation bar:
- (void)navigationController:(UINavigationController *)navigationController
willShowViewController:(UIViewController *)viewController
animated:(BOOL)animated {
navigationController.navigationBar.barStyle = UIBarStyleDefault;
}
This one works, however status bar style is still dark, while i need the default application one, so white.
Many thanks in advance!
Fixed my problem in a different way. To keep the status bar always the same i just added viewDidAppear method, that is written in my main post to my rootViewController, so it is same all the time including turning photo library on
The context:
I am working on an app that maintains a list of contacts along with their record IDs for it's own reference.
When the user needs to change the number associated with a specific contact within the app, I am trying to display the ABPersonViewController so the user can choose the new number from the contact in AB.
The problem:
The problem is that the ABPersonViewController that is opened is starting all the way from the top of the screen as if it does not know that there is a navigation bar on the top.
As a result some of the top part of the ABPersonViewController screen (the top part of the person image and the top part of the name) is underneath the navigation bar.
Ideally i want it to look like this, but not in edit mode: http://developer.apple.com/library/ios/documentation/ContactData/Conceptual/AddressBookProgrammingGuideforiPhone/Art/person_view.jpg
Also I wanted to add a "cancel" button to the top right part of the nav bar. Trying to add that as a bar button is not working either.
The code:
this is how I am adding the ABPersonViewController to the navigationController:
ABPersonViewController *personViewController = [[ABPersonViewController alloc] init];
personViewController.personViewDelegate = self;
personViewController.displayedPerson = person;
[self.m_circleNavController pushViewController:personViewController animated:YES];
[personViewController release];
The self here is a UIVIewController.
The m_circleNavController is the UINavigationController to which the UIVIewController belongs.
I tried these 2 ways of showing the person view, but both behave the same way.
[self.m_circleNavController pushViewController:personViewController animated:YES];
[self.navigationController pushViewController:personViewController animated:YES];
I'm not too sure what I am doing wrong, or what is the best way to do it.
I tried a lot of different ways to display it in vain.
The viewcontroller was behaving as though it was starting about 40 pixels above the top edge of the screen.
I was able to fix it in a very weird way finally. In the init function of the viewcontroller I added the following line:
self.view.bounds = CGRectMake(0, -43, 320, 440);
But still no clue as to why it happens this way. I was to close to the deadline to look for a decent solution.
Hello I've been having the same problem as of the new iOS. When this happens on my custom view controllers I have been able to correct it with:
if (self.interfaceOrientation != UIInterfaceOrientationPortrait) { // UI is in landscape position
[self.tableView setContentInset:UIEdgeInsetsMake(32,0,0,0)];
} else { // UI is in portrait position
[self.tableView setContentInset:UIEdgeInsetsMake(44,0,0,0)];
}
But when using the ABPersonViewController I don't quite know how to handle this problem.
Hope someone has an idea...
I'm playing around with this application I got on last months Web Designer that's a very basic RSS reader. I would like to add a refresh button to the top navigation bar that refreshes all the content in the table but can't seem to work out how to do it. I've worked out it must somehow use the [tablename Reload] function, but have got no idea how to implement it.
I'm new to all this so simple instructions are good instructions :) I know how to add the button, its linking it to and defining the actions when the user clicks it that I'm struggling with.
You can grab the code here http://www.webdesignermag.co.uk/tutorial-files/issue-162-tutorial-files/ under iPhone Apps (it's the only one).
This is what you need to do in the RootViewController.m:
In the viewDidLoad function, add a button of type UIBarButtonSystemItemRefresh, associate to it an Action and a Target, (infact, as Alan told you, you need to learn about Outlets and Actions)
UIBarButtonItem *refreshButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refreshTable)];
self.navigationItem.rightBarButtonItem = refreshButton;
Implement refreshTable function (if not declared in .h, have to put it above viewDidLoad())
- (void)refreshTable{
[rssParser release];
rssParser = [[RSSXMLParser alloc] init];
[rssParser parseRSSFeed];
[self.tableView reloadData];
NSLog(#"table is refreshing ....");
}
Hi Graeme and velcome to SO.
For the iphone UI, you have to define outlets and actions, and use Interface Builder to link them together.
This page has some information that should hopefully get you started.
