1) I declared UIWebView as a property with strong attribute (strong) called webView;
2) In viewDidLoad method I am checking if my web constant exists or not. Based on that I will create with implicit constant of my webView property called _webView;
3) Then [[UIWebView alloc] initWithFrame:] give to my _webView;
4) Finally sometimes it crashes on iOS 8 or iOS 9 or iOS7 platform with the picture i post here from Fabric CrashReport;
- (void)viewDidLoad {
[super viewDidLoad];
[self setBaseNaviBarInfo];
if (_webInfoDictionary.count > 0) {
NSString *titile = [_webInfoDictionary objectForKey:#"activityName"];
[self setNaviItemText:titile];
}
[self createViews];
CLS_LOG(#"init create wb view ......");
NSString* url = [_webInfoDictionary objectForKey:#"activityLink"];
[self loadWebViewWithURLString:url];
}
-(void)createViews{
if (!_webView) {
//Crash Now
_webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, STATUS_NAVI_STATUS_HEIGHT, IPHONE_WIDTH, IPHONE_HEIGHT - STATUS_NAVI_STATUS_HEIGHT)];
_webView.delegate = self;
_webView.scalesPageToFit = NO;
_webView.dataDetectorTypes = UIDataDetectorTypeNone;
[self.view addSubview:_webView];
_activityIndicatorView = [[UIActivityIndicatorView alloc] initWithFrame : CGRectMake(0.0f, 0.0f, 32.0f, 32.0f)] ;
[_activityIndicatorView setCenter: self.view.center] ;
[_activityIndicatorView setActivityIndicatorViewStyle: UIActivityIndicatorViewStyleGray] ;
[self.view addSubview : _activityIndicatorView];
}
}

I have a custom class A that is a subclass of UIView which essentially manages a UIScrollView that fits the size of the view and the contains an UIImageView that fills that scrollView.
I am having trouble setting the imageView.image of the custom class:
Here's the class
#import "BackgroundPickerView.h"
#implementation BackgroundPickerView
#synthesize scrollView;
#synthesize imageView;
#synthesize actionButton;
-(id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
return self;
}
-(void)layoutSubviews
{
[super layoutSubviews];
//[[NSNotificationCenter defaultCenter] addObserver:self
// selector:#selector(changeImage)
// name:#"ImageChangeNotification"
// object:nil];
//Here's where we add custom subviews
scrollView = [[UIScrollView alloc] init];
imageView = [[UIImageView alloc] init];
actionButton = [[UIButton alloc] init];
[scrollView setFrame:CGRectMake(0, 0, 321, 115)];
[imageView setFrame:CGRectMake(0, 0, 321, 115)];
[actionButton setFrame:CGRectMake(0, 0, 320, 115)];
scrollView.scrollEnabled = YES;
scrollView.minimumZoomScale = 1.0;
scrollView.maximumZoomScale = 6.0;
scrollView.contentSize = CGSizeMake(300, 200);//imageView.image.size;
[scrollView addSubview:imageView];
[self addSubview:scrollView];
}
-(void)storeImage:(UIImage *)image
{
self.imageView.image = image;
}
-(void)changeImage
{
[self.imageView setImage:[UIImage imageNamed:#"random.png"]];
}
From my other class B where I receive the image I have tried using NSNotification and a simple setter method to try setting the imageView property of the class object, but cannot seem to set the imageView.image. I have tried using
instance.imageView.image = myImageToSet
//Setter
[instance storeImage:myImageToSet];
in class B but am having no success
first of all, the initialisation of subviews in layoutSubviews not the best way, better u initialise them in the init method, because layoutSubviews may call multiple times to layout the subviews, if u place the initialisation code in the layoutSubviews there might be may subviews. in layoutSubviews u only set the frame of the subviews.
and u can do like below,
#import "BackgroundPickerView.h"
#implementation CustomViewA
//Edit change below
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if(self)
{
[self commonInit];
}
return self;
}
- (void)awakeFromNib
{
[self commonInit];
}
- (void)commonInit
{
_scrollView = [[UIScrollView alloc] init];
_imageView = [[UIImageView alloc] init];
_actionButton = [[UIButton alloc] init];
_scrollView.scrollEnabled = YES;
_scrollView.minimumZoomScale = 1.0;
_scrollView.maximumZoomScale = 6.0;
[_scrollView addSubview:_imageView];
[self addSubview:_scrollView];
}
- (void)layoutSubviews
{
[super layoutSubviews];
[_scrollView setFrame:CGRectMake(0, 0, 321, 115)];
[_imageView setFrame:CGRectMake(0, 0, 321, 115)];
[_actionButton setFrame:CGRectMake(0, 0, 320, 115)];
_scrollView.contentSize = CGSizeMake(300, 200);
}
-(void)storeImage:(UIImage *)image
{
self.imageView.image = image;
}
-(void)changeImage
{
[self.imageView setImage:[UIImage imageNamed:#"random.png"]];
}
synthesise is optional
and in BackgroundPickerView.h file it is something like below
#interface BackgroundPickerView : UIView
#property (nonatomic, strong) UIScrollView *scrollView;
#property (nonatomic, strong) UIImageView *imageView;
#property (nonatomic, strong) UIButton *actionButton;
-(void)storeImage:(UIImage *)image;
-(void)changeImage;
for image u check it it should work, check the image is present or not,
Edit
For the image, in controller for example,
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
_viewA = [[BackgroundPickerView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:_viewA];
}
//for testing
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[_viewA storeImage:[UIImage imageNamed:#"6.png"]]; //hear do this
}
I am trying to create a custom "alert view", nothing too fancy I just want to display a view overtop of the current view just like a UIAlertView.
Now here is the problem...I made the view in a nib file and now I want to alloc/init the view whenever I need to present an alert.Can anyone help me?
This is my attempt to get the view initialized...as of right now this crashes my app when I alloc/init a new alert view.
The app is crashing by telling me the view is not key-value compliant for the outlets.. I definitely have the outlets hooked up properly, unless I have a "File's Owner" thing screwed up.
NSObject 0x14e49800> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key....
- (id)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
if (self) {
[self load];
}
return self;
}
- (void)load {
NSArray *views = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:nil options:nil];
[self addSubview:[views firstObject]];
}
- (void)awakeFromNib {
[super awakeFromNib];
}
- (id)initWithFrame:(CGRect)frame
{
self = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:nil options:nil][0];
if (self) {
[self addSubview:self.contentView];
self.frame = frame;
}
return self;
}
- (instancetype)initWithTitle:(NSString *)title
message:(NSString *)message
delegate:(id)delegate
cancelButtonTitle:(NSString *)cancelButtonTitle
confirmButtonTitle:(NSString *)confirmButtonTitle {
self = [self initWithFrame:CGRectMake(0, 0, 320, 568)];
if (self) {
}
return self;
}
I made this method to present the view, just a simple addSubview...
- (void)showInView:(UIView *)view {
[view addSubview:self];
}
Try disabling autolayout and run the code.
Create a class same as below
#import "MyOverLay.h"
#interface MyOverLay (){
// control declarations
UIActivityIndicatorView *activitySpinner;
UILabel *loadingLabel;
}
#end
#implementation AcuOverLay
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
}
return self;
}
- (void)show:(NSString *)message{
// configurable bits
self.backgroundColor = [UIColor blackColor];
self.alpha = 0.75f;
self.autoresizingMask =UIViewAutoresizingFlexibleHeight;
float labelHeight = 22;
float labelWidth = self.frame.size.width - 20;
// derive the center x and y
float centerX = self.frame.size.width / 2;
float centerY = self.frame.size.height / 2;
// create the activity spinner, center it horizontall and put it 5 points above center x
activitySpinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
activitySpinner.frame = CGRectMake(centerX - (activitySpinner.frame.size.width / 2) , centerY - activitySpinner.frame.size.height - 20, activitySpinner.frame.size.width, activitySpinner.frame.size.height);
activitySpinner.autoresizingMask = UIViewAutoresizingFlexibleHeight;
[self addSubview:activitySpinner];
[activitySpinner startAnimating];
// create and configure the "Loading Data" label
loadingLabel = [[UILabel alloc]initWithFrame:CGRectMake(centerX - (labelWidth / 2), centerY + 20 , labelWidth, labelHeight)];
loadingLabel.backgroundColor = [UIColor clearColor];
loadingLabel.textColor = [UIColor whiteColor];
loadingLabel.text = message;
loadingLabel.textAlignment = NSTextAlignmentCenter;
loadingLabel.autoresizingMask = UIViewAutoresizingFlexibleHeight;
[self addSubview:loadingLabel];
}
- (void)hide{
[UIView animateWithDuration:0.5 animations:^{
self.alpha = 0;
[self removeFromSuperview];
}];
}
#end
then create instance wherever you want
loadingOverlay = [[MyOverLay alloc]initWithFrame:[UIScreen mainScreen].bounds];
loadingOverlay.tag = 999;
[[[UIApplication sharedApplication] keyWindow] addSubview:loadingOverlay];
[loadingOverlay show:#"Saving ..."];
I have an abstract class that is a UIView subclass.
It creates a view on a new UIWindow and shows my Custom alert to users.
I have an AuthorizationView class inherited from this abstract class and it contains some UITextFields.
The problem is: these UITextFields doesn't respond on iOS 7.1 beta if I build it now and send to testers.
Old versions of project work fine (from AppStore) on iOS 7.1 beta.
Any version works fine on iOS 6.0 - iOS 7.0. I have no possibility to test it myself on iOS 7.1 beta.
Any suggestions?
UITextField creation:
fieldUser = [[UITextField alloc] initWithFrame:AUTH_FIELD_USER_FRAME];
[fieldUser setBackgroundColor:kColorClear];
[fieldUser setBorderStyle:UITextBorderStyleNone];
[fieldUser setTextAlignment:NSTextAlignmentLeft];
[fieldUser setKeyboardType:UIKeyboardTypeEmailAddress];
[fieldUser setKeyboardAppearance:[[DatabaseManager sharedInstance] keyboard]];
[fieldUser setContentVerticalAlignment:UIControlContentVerticalAlignmentCenter];
[fieldUser setAutocorrectionType:UITextAutocorrectionTypeNo];
[fieldUser setAutocapitalizationType:UITextAutocapitalizationTypeNone];
[fieldUser setReturnKeyType:UIReturnKeyNext];
[fieldUser setDelegate:self];
[fieldUser setPlaceholder:NSLocalizedString(#"Window_Login_Placeholder_User", #"")];
[fieldUser setFont:kFontNormal(16.0f)];
[self addSubview:fieldUser];

All the Event Delegate methods will touch the main Window of the application. Now you have created another window, may be your delegate is calling, but hiding because this new Window. Just make window color clear color and verify, or else try with printing text of Text Field entering some text, will let you know is triggered or not?
I'm using a CvVideo Camera thus:
- (void)viewDidLoad
{
[super viewDidLoad];
self.videoCamera = [[CvVideoCamera alloc] initWithParentView:imageView];
self.videoCamera.delegate = self;
self.videoCamera.defaultAVCaptureDevicePosition = AVCaptureDevicePositionBack;
self.videoCamera.defaultAVCaptureSessionPreset = AVCaptureSessionPresetiFrame960x540;
self.videoCamera.defaultAVCaptureVideoOrientation = AVCaptureVideoOrientationPortrait;
self.videoCamera.defaultFPS = 30;
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self.videoCamera start];
}
My storyboard looks like this:
When the view loads, the bar is visible briefly with the rest of the view white. Then when the camera starts it fills the whole screen. Why is it doing this?
Have you tried with a different parent view?
UIView *camView = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 300, 400)];
[self.view addSubview:camView];
self.videoCamera = [[CvVideoCamera alloc] initWithParentView:camView];
I want my whole project to run in portrait mode only and only the view that's for viewing the photo's can turn on landscape same as if using the facebook (we view photo's they turn landscape also but other view's remains in portrait) i want to know that how it's done as i have a table view that has images that i get from the DB from the server and every particular data contains different number's of photo's so now i want that after the user select's the photo's they should open up fully and can be viewed in landscape and in portrait as well i did tried
I am working with ios6
- (BOOL)shouldAutorotate
{
return NO;
}
implementing in all the view's so that they can remain in portrait but still they turn in landscape how should i restrict it and please can any one tell me that in one of my class i have images in table view(loaded from the DB) and i have another class that open's up the selected photo from the table
My PhotoView.m class

and in the main class i have have this method that calls the PhotoViewController to load the selected photo

Now my problem is how should i get the images after getting selected from the table to be open up in the same type of the view that open's up in FB app (open's the selected photo in portrait/landscape compatible view) i am only able to get one photo in my PhotoViewController class can any one tell me how can i add all the photo's to the PhotoViewController class so that i get the effect that i want ?... Any code help will be very helpful .. Thanks in Advance for contributing your time
In Short i have two things to do :
I have to restrict my project to only portrait mode leaving only the photo's view to have landscape/portrait compatibility.
I am currently having the photo's in my table view that i want on selection to open up in the same style(landscape/portrait compatibile) as FB or other app's do while viewing the photo's.
These only work on iOS 6.0
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft);
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
The method will return which orientation mode to use first.
Below are supportedInterfaceOrientations:
UIInterfaceOrientationMaskPortrait
UIInterfaceOrientationMaskLandscapeLeft
UIInterfaceOrientationMaskLandscapeRight
UIInterfaceOrientationMaskPortraitUpsideDown
UIInterfaceOrientationMaskLandscape
UIInterfaceOrientationMaskAll
UIInterfaceOrientationMaskAllButUpsideDown
For iOS > 4.0
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
Other ViewControllers will have
-(BOOL)shouldAutorotate { return NO; }
-(BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation{
return NO;
}
