I'm trying to ask the user to input their name in a SKScene but whenever I add a subview it messes up the SKScene and it starts to replay the music and doesnt add the new SKScene that I have the textfield in. Here is my attempt.
-(void)didMoveToView:(SKView *)view{
self.backgroundColor = [SKColor lightGrayColor]; // NOTE: temporary background color se
UILabel *nameField = [[UILabel alloc] initWithFrame:CGRectMake(200, 200, 300, 100)];
[self.view addSubview:nameField];
//[self createMenuTxt];
[self SetBrickBackground];
}
EDIT: I found a related post:
Adding UITextView to a scene in SpriteKit
Which says that the reason is because the skScene is being presented everytime I add a UITextview. He said to use a guard: if(self.view.scene == nil){}, however, I'm getting that scene is not a property of UIView. Am I missing something?
In this case self is the view. So in effect you are saying self.self which obviously does not work.
Change the line [self.view addSubview:nameField]; to this [view addSubview:nameField];

This problem can be demonstrated by creating a new project in Xcode (I am using version 6.4) and using the following code:
#interface ViewController ()
#property (nonatomic, strong) UITextField * myTextField;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.myTextField = [[UITextField alloc] initWithFrame:CGRectMake(50, 50, self.view.frame.size.width-100, 50)];
self.myTextField.textAlignment = NSTextAlignmentRight;
[self.myTextField becomeFirstResponder];
self.myTextField.backgroundColor = [UIColor lightGrayColor]
self.myTextField.adjustsFontSizeToFitWidth = YES;
self.myTextField.font = [UIFont systemFontOfSize:40];
[self.view addSubview:self.myTextField];
}
- (void) viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
self.myTextField.text = #"1.5241578750119E18";
}
When running this project in iOS Simulator (iPhone 5 or 5S), the cursor is initially displayed after the last "1", and the "8" is not visible until a new character is typed.
This appears to be a bug by Apple, but my question is: is there a workaround for now that will force the text to right-align and show the cursor in the correct position?
To clarify the question further, the issue occurs when the text is set programmatically. I expect to see this:
But instead I am seeing this (note that the entire number is not visible and the cursor is showing after the "1" instead of the last digit which is an "8"):
This is a bug, existing in iOS, since iOS 7. Issue can be reproduced in stock applications like Settings as well. It affects text fields only when NSTextAlignmentRight is used. The original bug ID logged into Radar for this issue is 14485694. You may use centre or left text alignments, to circumvent this problem.
I would also suggest to file a new bug report to Apple,
Try this
UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 20)];
self.myTextField.leftView = paddingView;
self.myTextField.leftViewMode = UITextFieldViewModeAlways;
it will add some space to the left side of your TextField so that your cursor starts at correct position.
Hope it helps.
If I change your code to this:
- (void)viewDidLoad {
[super viewDidLoad];
self.myTextField = [[UITextField alloc] initWithFrame:CGRectMake(5, 50, self.view.frame.size.width-10, 50)];
self.myTextField.textAlignment = NSTextAlignmentRight;
[self.myTextField becomeFirstResponder];
self.myTextField.backgroundColor = [UIColor lightGrayColor];
self.myTextField.adjustsFontSizeToFitWidth = YES;
self.myTextField.font = [UIFont systemFontOfSize:60];
[self.view addSubview:self.myTextField];
}
And start typing in those numbers, the cursor ends up along the right edge of the text field just as it's supposed to.
Even when I start the app with the default value in the text, I see the cursor along the right edge of the text field fine.
Listening to UITextFieldTextDidChangeNotification notification instead of UIControlEventEditingChanged will fix the issue.
I met the same issue, try add dummy code like this
(void)textFieldDidBeginEditing:(UITextField *)textField {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
textField.text = textField.text;
});
}
I'm working on example from "iOS Programming Cookbook", based on iOS 7. I need to create UITextField and add it to ViewController.
In ViewController.m I have:
- (void) viewDidLoad {
[super viewDidLoad];
[self createField];
}
- (void) createField {
self.textField = [[UITextField alloc] initWithFrame:CGRectMake(20.0f, 35.0f, 280.0f, 30.0f)];
self.textField.translatesAutoresizingMaskIntoConstraints = NO;
self.textField.borderStyle = UITextBorderStyleRoundedRect;
self.textField.placeholder = #"Enter text to share";
self.textField.delegate = self;
[self.view addSubview:self.textField];
}
On screenshot from book textField appears in the middle of screen's width under the status bar, but when I run it textField appears on the top left corner of screen behind the status bar.
Maybe the problem is, that I run app on iPhone 6 simulator with iOS 8. But I don't know how to solve it.
Thanks!
Using self.textField.translatesAutoresizingMaskIntoConstraints = NO; is pretty much telling the object that it doesn't really care about the frame but relies more on the constraints that you give it. Setting it to YES takes the frame and automatically applies constraints to it to mimic the frame that you give it.
For example it would apply the constraints to have the frame appear at: CGRectMake(20.0f, 35.0f, 280.0f, 30.0f). When setting it to NO use NSLayoutConstraint and create the constraints programatically.
But in your case just remove the line
self.textField.translatesAutoresizingMaskIntoConstraints = NO;
because it is set to YES by default.
How can i place a UIView on top of the Chartboost ad?
I tried everything. I am using the Chartboost delegate to know when an ad is displayed and then I add the UILabel but it will just get dimmed out by the Chartboost ad.
I even tried the method [self.view bringSubviewToFront:label]; but it did not work.
Anyone knows a workaround so I can display this label without it getting dimmed out by the Chartboost interstitial.
This is the code I use for the ad (The timer was just for testing):
-(BOOL)shouldDisplayInterstitial:(NSString *)location {
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, -150 /2, 500, 300)];
label.textColor = [UIColor whiteColor];
label.text = #"Tap ad to get a boost";
label.font = [UIFont fontWithName:#"AvenirNext-DemiBold" size:32.6];
label.alpha = 1;
[self runAction:[SKAction waitForDuration:5] completion:^{
self.view.window.rootViewController.view = label;
}];
return YES; }
While this may be possible, it's viewed as artificially inflating (or incentivizing) clicks. These types of things are scanned for & regularly shut down.
Instead, use a number of interstitial locations in your app. Test which locations work best & at what frequency and focus your efforts there.
Full disclosure: I work at Chartboost.
I created a UITextField programatically, (I do not use storyboard) and added it as a subview to ViewController with this code:
#interface ViewController ()
#property (nonatomic, strong) UITextField *searchLocationBar;
#end
...
#synthesize searchLocationBar;
...
self.searchLocationBar = [[UITextField alloc] init];
self.searchLocationBar.frame = CGRectMake(0.0f, 0.0f, 320.0f, 40.0f);
self.searchLocationBar.delegate = self;
self.searchLocationBar.borderStyle = UITextBorderStyleRoundedRect;
self.searchLocationBar.placeholder = #"a temporary placeholder";
self.searchLocationBar.userInteractionEnabled = YES;
self.searchLocationBar.clearButtonMode = UITextFieldViewModeAlways;
[self.view addSubview:self.searchLocationBar];
However, I cannot enter any text - nothing happens, when I tap on a textfield. It's not overlapped by any other view.
I've checked UITextfield not editable-iphone but no effect
I'm newbie and totally sure I simply miss something - please advice.
Thanks!
EDIT:
One more thing: I have a Google Maps GMSMapView assigned to self.view as
self.view = mapView_; as written in Google API documentation.
After some tests I found that with this declaration all controls work perfectly, but not textfields. I would prefer not to move a map view to any subview as I will need to rewrite lots of things.
Can someone please add any suggestions?
you forget add:
[self.view bringSubviewToFront:self.searchLocationBar];
In Xcode 5 your code should work.Better you check your Xcode version.May be the problem with your code with Xcode versions.You can try by following way.
UITextField *lastName = [[[UITextField alloc] initWithFrame:CGRectMake(10, 100, 300, 30)];
[self.view addSubview:lastName];
lastName.placeholder = #"Enter your last name here"; //for place holder
lastName.textAlignment = UITextAlignmentLeft; //for text Alignment
lastName.font = [UIFont fontWithName:#"MarkerFelt-Thin" size:14.0]; // text font
lastName.adjustsFontSizeToFitWidth = YES; //adjust the font size to fit width.
lastName.textColor = [UIColor greenColor]; //text color
lastName.keyboardType = UIKeyboardTypeAlphabet; //keyboard type of ur choice
lastName.returnKeyType = UIReturnKeyDone; //returnKey type for keyboard
lastName.clearButtonMode = UITextFieldViewModeWhileEditing;//for clear button on right side
lastName.delegate = self; //use this when ur using Delegate methods of UITextField
There are lot other attributes available but these are few which we use it frequently.if u wanna know about more attributes and how to use them refer to the following link.
You can also make property for UITextField.Either way should work fine in Xcode.

I am facing a problem with updating my labels.. it doesn't remove the old values so new values go on top of old ones.. any help with this will be appreciated..
timer = [NSTimer scheduledTimerWithTimeInterval:1
target:self
selector:#selector(updateLabels)
userInfo:nil
repeats:YES];
-(void) updateLabels{
for (GraphView *graph in arr){
// retrieve the graph values
valLabel = [[UILabel alloc] initWithFrame:CGRectMake(i * 200, 0, 90, 100)];
valLabel.textColor = [UIColor whiteColor];
valLabel.backgroundColor = [UIColor clearColor];
valLabel.text = [NSString stringWithFormat:#"Value: %f", x];
i++;
}
}
If you set the text of your label you do not need to call setNeedsDisplay or clearContext etc.
In your code, I do not know what are your variables i and x?
The main problem is that you are creating and adding new labels on your view. When you call updateLabels method, may cause a Memory leak. Simply you have n times labels overlapped.
You need to remove the labels before you create and add new labels or you can reuse which you already have. To reuse your labels you need to save them to an array and update texts.
If you want to create new labels then you can do like this unless you have other labels in your view
-(void) updateLabels{
// remove all labels in your view
for (UIView *labelView in self.view.subviews) {
if ([labelView isKindOfClass:[UILabel class]]) {
[labelView removeFromSuperview];
}
for (GraphView *graph in arr){
// retrieve the graph values
valLabel = [[UILabel alloc] initWithFrame:CGRectMake(i * 200, 0, 90, 100)];
valLabel.textColor = [UIColor whiteColor];
valLabel.backgroundColor = [UIColor clearColor];
valLabel.text = [NSString stringWithFormat:#"Value: %f", x];
i++;
}
}
When you create new labels like this you need to add them to your view as subview
[self.view addSubview: valLabel];
if you have other labels in your view then you can save them in an array and remove just them
Your updateLabels method is actually creating new UILabel controls each time so they will simply appear "on top of" older ones. I'm guessing this is not what you want, although it's not perfectly clear so apologies if I've misunderstood what you're trying to do.
If I'm correct about that, create your UILabel controls just once maybe in your viewDidLoad or similar. Then just set their .text properties when your timer fires.
You need to call setNeedsDisplay so that the app knows it has changed and redraw it.
- (void)setNeedsDisplay
Set clearsContextBeforeDrawing property of your label to YES
you can set this from nib as well as code.
label.clearsContextBeforeDrawing = YES;
