UiWebView delegate methods not getting called - ios

I am trying to play youtube embedded video in webView it plays when i don't set delegate and If i set delegate video dosen't load and delegates methods are also not getting called. Here is MY Code:
.m class
#import "EmbeddedVideoVC.h"
#interface EmbeddedVideoVC (){
MBProgressHUD *hud;
}
//#property (weak, nonatomic) IBOutlet UIWebView *webView;
#property (weak, nonatomic) IBOutlet UIView *viewSelf;

#end
#implementation EmbeddedVideoVC
- (void)viewDidLoad {
[super viewDidLoad];
self.view.transform = CGAffineTransformMakeRotation(M_PI/2);
}
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
CGRect bounds = [[UIScreen mainScreen] bounds];
if ([SharedAppManager sharedInstance].applicationFrame.size.height < 568) {
bounds = CGRectMake(0, 0, 480, 320);
}
_videoWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0,bounds.size.height, bounds.size.width)];
[_videoWebView setAllowsInlineMediaPlayback:YES];
[_videoWebView setMediaPlaybackRequiresUserAction:NO];
[self.viewSelf addSubview:_videoWebView];
hud = [MBProgressHUD showHUDAddedTo:_videoWebView animated:YES];
hud.color = [UIColor clearColor];
hud.activityIndicatorColor = [UIColor whiteColor];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(didTapMethod)];
[tap setNumberOfTapsRequired:1]; // Set your own number here
[tap setDelegate:self]; // Add the <UIGestureRecognizerDelegate> protocol

CAN ANYONE tell me what is the problem and why webViewDidFinishLoad: and others delegates methods not getting called and even embedded code not loading in webview?

Just put your UIWebView related code in viewDidAppear: method.
Reference : https://stackoverflow.com/a/27647327/2284065

1) Please make sure you are adding web view on present class view or on any top view.
2) Are you adding viewSelf in storyboard? since i cannot see it programmatically. Make sure of it, because you are adding web view to viewSelf.
3) In hideControllers you are hiding some topView. Make sure it is not the present class topView.
Here is the code working for me (delegate methods are also calling),
_videoWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0,self.view.frame.size.width, self.view.frame.size.height)];
[_videoWebView setAllowsInlineMediaPlayback:YES];
[_videoWebView setMediaPlaybackRequiresUserAction:NO];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(didTapMethod)];
[tap setNumberOfTapsRequired:1]; // Set your own number here
[tap setDelegate:self]; // Add the <UIGestureRecognizerDelegate> protocol
[_videoWebView addGestureRecognizer:tap];
_videoWebView.delegate= self;
NSURL *nsurl=[NSURL URLWithString:#"http://www.google.com"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[_videoWebView loadRequest:nsrequest];
[self.view addSubview:_videoWebView];
Hope this helps.

uiwebview with header and footer

I am trying to add header and footer (both of them as UIViews) but for some reason my footer sticks to the bottom, I'm using the KVO method for watching my content size.
I'm presenting here the method where I think the problem is:
- (void)updateLayout
{
// Update the frame of the header view so that it scrolls with the webview content
CGRect newHeaderFrame = self.headerView.frame;
CGRect newFooterFrame = self.footerView.frame;
newHeaderFrame.origin.y = -CGRectGetMinY([self.webView convertRect:self.innerHeaderView.frame toView:self.webView.scrollView]);
newFooterFrame.origin.y = self.webView.scrollView.contentSize.height;
[self.headerView setFrame:newHeaderFrame];
[self.footerView setFrame:newFooterFrame];
if ([self didTapToFullScreen])
{
// The delegate was already called in this case, in the tap gesture callback method
return;
}
BOOL fullScreen = (newHeaderFrame.origin.y < 0);
if (([self isZooming] && [self didSwitchToFullScreen]) || (fullScreen == [self isFullScreen]))
{
return;
}
[self setSwitchToFullScreen:fullScreen];
[self setFullScreen:fullScreen];
// Call the delegate for the full screen
[self.fullScreenDelegate emailView:self showFullScreen:fullScreen];
}
Here's the full project
How I can place the footer to the bottom of the UIWebView ?
You can set the views on UIWebView scroll view, and fiddle with the offsets.
#interface ViewController ()<UIWebViewDelegate>
#property (weak, nonatomic) IBOutlet UIWebView *webView;
#property (nonatomic, strong) UIView *headerView;
#property (nonatomic,strong) UIView *footerView;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.headerView = [[UIView alloc] initWithFrame:CGRectMake(0, -100, [UIScreen mainScreen].bounds.size.height, 100)];
self.headerView.backgroundColor = [UIColor blueColor];
self.footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)];
self.footerView.backgroundColor = [UIColor yellowColor];
NSString *urlText = #"http://stackoverflow.com/questions/15921974/how-to-load-url-on-launch-in-a-webview-osx-project";
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlText]]];
self.webView.delegate = self;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - WebView delegate
-(void) webViewDidFinishLoad:(UIWebView *)webView {
self.webView.scrollView.contentInset = UIEdgeInsetsMake(100.0,0.0,100.0,0.0);
if(![self.headerView superview])
{
[webView.scrollView addSubview:self.headerView];
[webView.scrollView bringSubviewToFront:self.headerView];
}
NSString *result = [webView stringByEvaluatingJavaScriptFromString:#"document.body.offsetHeight;"];
NSInteger height = [result integerValue];
self.footerView.frame = CGRectMake(0, height, [UIScreen mainScreen].bounds.size.height, 100);
if(![self.footerView superview])
{
[webView.scrollView addSubview:self.footerView];
[webView.scrollView bringSubviewToFront:self.footerView];
}
[self.webView.scrollView setContentOffset:
CGPointMake(0, -self.webView.scrollView.contentInset.top) animated:NO];
}
#end
Another option would be to add top padding to the HTML ("margin-top:100px") and then the header view would not be in minus offset.

Add a UITapGestureRecognizer to a subview

I have been searching for hours ... Needless to say, I'm rather new in programming.
My goal is to display a subview programmatically and to remove it by tapping on it.
Already working: Displaying the subview and removing it by tapping on the view (code below).
Doesn't work - whatever I try: Removing the subview by tapping exclusively on the subview.
Thanks for your help!
My .h-file:
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController {
UIImageView *canvas;
UIImageView *square;
}
#property (nonatomic, strong) UIImageView *canvas;
#property (nonatomic, strong) UIImageView *square;
#property (nonatomic) NSUInteger numberOfTouchesRequired;
- (void)handleSingleTap: (UITapGestureRecognizer *)singleTapGestureRecognizer;
#end
My .m-file:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize canvas;
#synthesize square;
- (void)handleSingleTap: (UITapGestureRecognizer *)singleTapGestureRecognizer {
NSLog(#"tapGesture");
[square removeFromSuperview];
}
- (void)loadView {
canvas = [[UIImageView alloc] initWithFrame: [[UIScreen mainScreen] applicationFrame]];
[canvas setImage:[UIImage imageNamed:#"canvas.png"]];
self.view = canvas;
square = [[UIImageView alloc] initWithFrame:CGRectMake(170, 320, 40, 40)];
[square setImage:[UIImage imageNamed:#"square.png"]];
[self.view setUserInteractionEnabled:YES];
[canvas addSubview:square];
NSLog(#"square");
}
- (void)viewDidLoad {
[super viewDidLoad];
UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleSingleTap:)];
NSLog(#"initialize");
singleTapGestureRecognizer.numberOfTapsRequired = 1;
NSLog(#"number of taps");
[self.view addGestureRecognizer:singleTapGestureRecognizer];
NSLog(#"square gestureRecognizer");
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
If you want to remove a subview exclusively, when you tap on that view, then you will need to add tap gesture on that view
[square addGestureRecognizer:singleTapGestureRecognizer];
rather than
[self.view addGestureRecognizer:singleTapGestureRecognizer];
Edit
Also you will need to setUserInteractionEnabled to YES of UIImage because UIImage's setUserInteractionEnabled is default to NO.
[square setUserInteractionEnabled:YES];
Instead of
[self.view addGestureRecognizer:singleTapGestureRecognizer];
you should say
[square addGestureRecognizer:singleTapGestureRecognizer];

Showing TextView and Typing Text in TextView if i click any places in ImageView

I want to show TextView and I want to type the text in the TextView.
Whenever I click or Touch any place in the ImageView.
Here actually I set the UITapGestureRecognizer for TextView.
Also once I type the text in the TextView it should be a Automatic saveable.
Here I set the ImageView.After that i set the SubView and inside the SubView i set ImageView for Zoom.
Now I get the Zoom image. Exactly if I click or Touch any places in the Zoom ImageView,it should show the TextView as well as once I Type Text in the TextView,it should be a Automatic saveable.
But I can't get the TextView, whenever I click or Touch in the Zoom ImageView.
How can I get that?

actually you need to modify the some lines because you were created the tapgesture4 in before allocation of dynamic view, that the reason it showing at null, now u simply do a simple change, just convert the tapgesture4 into tapdetected2 method now check, it work surely fine for u.

How to set text of another class? [duplicate]

This question already has answers here:
Passing data between view controllers
(45 answers)
Closed 8 years ago.
What I have is menu at the top (vertical slider). On the top I have button, on clicking this button, the view will get scroll down and display the menu.
For this what I am doing is creating a view and showing it at top.
Now when I click on the button, I am planning to change the frame of top view with animation.
I am able to handle the frame and animation, however problem I am facing is setting the text to the right label and left button.
Below is the dropbox link to download the sample project. Any idea/ solution will be appreciated.
https://www.dropbox.com/s/pdaelw2k8ljnaki/TwoView.zip
What I tried is below code
CommonViewController *newClass = [[CommonViewController alloc] init];
newClass.parentObject = self;
NSLog(#"text is %#", newClass.rightSideLabel.text);
newClass.rightSideLabel.text = #"NEW VALUE HERE";
However still on the right side I see products only.

// Dispose of any resources that can be recreated.
}
#end
What I want to do is keep common things in CommonViewController
Below is what I did...
In bViewController.m, I added below.
[[NSUserDefaults standardUserDefaults] setValue:#"New Value Here" forKey:#"notValue"];
[[NSUserDefaults standardUserDefaults] synchronize];
[[NSNotificationCenter defaultCenter] postNotificationName:#"ChangeRightSideLabel" object:self];
And in CommonViewController.m, viewDidLoad
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(receiveTestNotification:) name:#"ChangeRightSideLabel" object:nil];
- (void) receiveTestNotification:(NSNotification *) notification
{
// [notification name] should always be #"TestNotification"
// unless you use this method for observation of other notifications
// as well.
if ([[notification name] isEqualToString:#"ChangeRightSideLabel"]) {
NSLog (#"Successfully received the test notification!");
trightSideLabel = [[NSUserDefaults standardUserDefaults] valueForKey:#"notValue"];
rightSideLabel.text = trightSideLabel;
}
}
You have to respect MVC design Pattern approach. So instead of "newClass.rightSideLabel.text = #"NEW VALUE HERE";" You have to write :
in NewClass.h:
-#property(strong,nonatomic) stringText;
in NewClass.m:(ViewDidLoad Method)
-rightSideLabel.text=stringText;
in the current class:
-newClass.stringText= #"NEW Value HERE";
You need to make a string property for CommonViewController and assign the text to it.
And in CommonViewController's ViewDidLoad set that text to rightSideLabel.

.xib file init UIView on ViewController User interaction not working

I have a Storyboard with a ViewController using a navigation controller and a TabBarController. I have been trying to resolve this for a few days now.
The problem:
Very often user I cannot interact with the view... that includes scrolling, tapping the text field and any buttons being pressed. Something is stopping me from interacting with the newly loaded UIView.
I have tried using the init method and tried using the init with frame method. The view is showing all the time though so maybe this is not the problem.
I have tried remaking the whole xib file, re-coding the .h and .m files and re-attaching all the outlets on the view.
I am stuck
In the view controller I am loading a UIView with separate .xib file and separate .h and .m file.
This is how I am doing it:
in my ViewController in the viewDidAppear method:
int startPos = self.navigationController.navigationBar.frame.size.height+20;
inviteFriendsView = [[InviteFriendsEmailAddressesView alloc] init];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"InviteFriendsEmailAddressesView" owner:self options:nil];
inviteFriendsView = (InviteFriendsEmailAddressesView*)[nib objectAtIndex:0];
[self.view addSubview:inviteFriendsView];
[inviteFriendsView setDelegate:self];
[inviteFriendsView setUserInteractionEnabled:YES];
[inviteFriendsView customizeView];
[inviteFriendsView setAlpha:0.0];
[inviteFriendsView setY:startPos];
IBAction method for showing the view:
- (IBAction)inviteFriendsButtonTapped:(id)sender {
[self.view bringSubviewToFront:inviteFriendsView];
[inviteFriendsView setUserInteractionEnabled:YES];
[inviteFriendsView animate];
}
Here is the .h and .m files which show how I am loading the view:

This might be an issue with the frames, where the controls are rendered (partially) outside the superview frame. This can be caused by invalid autoresizing masks or autolayout constraints.
To debug this you can set 'clip subviews' to YES for the relavant controls. When you see some of the controls are not visible anymore (or just partially), check the frames and resizingmasks or constraints of the superview.
Check whether the view controller is added in the build phase compile source. If you not added the view controller in the compiler source (if its not added automatically) it will some effect in xib integration.
I found the answer. I had to comment out the line
[[self superview] setUserInteractionEnabled:NO];
inside slideIn(){..}
So disabling user interaction for the superview would of course stop all user interaction from happening in a subview (such as the scrollview).
Oh dear.
Thanks guys!
