iOS text field doesn't show placeholder text - ios

So I have some basic textfields with a custom background, that is a line at the bottom and the rest of it it's transparent, but now the placeholders don't show anymore.
These are the text fields
And config

I have found a solution that works, you need to select the input and set the following on User Defined Runtime Attributes

It's better to do this:
if ([self.textField respondsToSelector:#selector(setAttributedPlaceholder:)]) {
self.textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:self.textField.placeholder attributes:#{NSForegroundColorAttributeName: [UIColor whiteColor]}];
}

I had the same problem. Turns out it had nothing to do with me having set borderStyle to UITextBorderStyleNone. It was caused by me subclassing UITextField to add a manually drawn border along the bottom only and failing to call the super implementation in my override of layoutSubviews. Once I had sorted that, my placeholder text was back.

UITextField, set placeholder after text in ios

I need to keep the placeholder after the text, when click on the text box i need to clear only the placeholder and able to type characters.
In this Marissa is the name text and (First Name) is placeholder. Once i start editing placeholder need to clear and start editing complete text.
How can i achieve that?
I have found some similar custom textfield in the below URL. If you find this suitable, you can use it.
TUTORIAL / SOURCE
Please refer below code.
Just copy-paste below code in viewdidload()
textfield.attributedPlaceholder = [[NSAttributedString alloc] initWithString:[NSString stringWithFormat:#"Yourtext%#",Placehodertext] attributes:#{NSForegroundColorAttributeName: color}];
Assign Delegate of UITextfield to self.
textfield.delegate = self
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
textfield.text = #"Yourtext"
return YES;
}
You can not set place holder along with the text in a textfield.
But there is one alternate for this.
Textfields has something called left view which you can make readOnly view.
Try this :
UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
UILabel *textLabel = [[UILabel alloc] initWithFrame:paddingView.bounds];
textLabel.text = #"Marissa";
[paddingView addSubView:textLabel];
textField.leftView = paddingView;
textField.leftViewMode = UITextFieldViewModeAlways;
Step 1:
Make the text filed attributed form xib and set the "Marisa (First Name)"
and change the color for the (First Name) as grey color .
Step 2:
And in the Textfiled DidBiginEditing method change the textField.text to "Marisa".
This could be achieved in several ways:
Use the attributedText property of UITextField instance to apply a styling for different parts of the text. Here you need to properly define the property each time a user has changed the input by using delegate methods or by observing UIControl Control Events.
If the structure of the text input is fixed and predefined you could use a batch of fields to imitate a more complex/smart field. Here, for example, you need to put two fields beside. One for the last name, second for the first name. Or you can use a combination of UILabel and UITextField if one the part is not editable. Such an approach allows you to configure a separate part of a complex field as you want: different placeholders, fonts, keyboard styles, etc.

UISearchBar placeholder text color/location

However, I've applied different patches still I'm not able to fix placeholder text position and text color for UISearchbar.
But when I type something, it's showing up at a proper place.
What's the reason?
This is how you can change the colour of your placeholder text:
UITextField *searchField = [self.searchBar valueForKey:#"searchField"];
searchField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:#"Some Text"];
UILabel *placeholderLabel = [searchField valueForKey:#"placeholderLabel"];
placeholderLabel.textColor = [UIColor blueColor];
As for the position, by default, placeholder text is vertically centre positioned in the UISearchBar. From your screenshot, it appears to me that there are few new line characters in the end of the text.
there's a category created on UITextField, inside it, the placeholder text is drawing. I just corrected the frame and now everything works fine, even that solve the color issue as well.

How can I change a UILabel's text color back to what it was when the program first launched in Xcode for iOS 7?

When programming in Obj-C for iPhone, it is often necessary to adjust the text color of objects such as labels, buttons, etc. I get that we usually do this by using code like:
myLable.textColor = [UIColor redColor];
Now my problems arise when the color I started with is not one of the pre-defined UIColors. I can change its text's color to any of the pre-defined (as in this case, red), but how can I revert the color to the one I chose in the storyboard (the color of the label's text as the program first starts)?
Thanks in advance for your help!
As my comment suggests, you should create a property to later access your custom color like this:
#property (nonatomic, strong) UIColor *myColor;
- (void)viewDidLoad
{
// Set the values as the ones in storyboard. Make sure to always divide by 255.0!
self.myColor = [UIColor colorWithRed:(255.0/255.0) green:(59.0/255.0) blue:(48.0/255.0) alpha:1.0];
// Set the label's text color property to our custom color.
myLabel.textColor = self.myColor;
}
In storyboard, click here to find the exact color you need:

Customising the Text Field

So - I am experimenting at the moment with app design.
This is my concept:
See the blue line? That should be where the users "cursor" starts and cant go negativaly behind that point, but can move positively until the end of the box.
As long as the UITextField starts after the colon and does not extend beyond the cell's trailing edge, you should have no issues. Are you laying out using code or Interface Builder?
I have done the similar UI using UITableview. Code to set the Username label for the cell in cellForRowAtIndexPath (use similar code for Password row):
tableViewCell.textLabel.text = #"Username:";
Here is the code to set the text field:
UITextField *textField = [[UITextField alloc] initWithFrame:textFieldRect];
//Insert code for text field delegate and properties e.g. keyboardType, autocorrectionType
tableViewCell.accessoryView = textField;

Text in UITextView not display correctly, invisible, but occupied spaces

There is a UITextView in the view, the view controller is showing with Modal style. In my viewDidLoad method, I set the text of this UITextView, but, the text is not showing. Image below showing the error. Text color is black.
The weird thing is , when I long tap in the text view or tap [return] in keyboard, the text become visible. One thing I noticed is this error only occurred when the text I set is longer than the UITextView frame width, and the last word is not broken such as a long url.
I think the problem is maybe the word wrap not work correctly.
Thanks in advance.
Code like below:
UITextView *myTextView = [[UITextView alloc]initWithFrame:CGRectMake(10, 10, 520, 220)];
myTextView.textColor = [UIColor blackColor];
myTextView.font = [UIFont systemFontOfSize:20];
myTextView.layer.cornerRadius = 5;
myTextView.delegate = self;
myTextView.text = #"long text should some like http://stackoverflow.com/posts/11200726/edit";
[self.view addSubview:myTextView];
[myTextView release];
RESOVLED. In viewDidLoad method, add code below:
CGRect tempFrame = myTextView.frame;
[myTextView setFrame:CGRectZero];
[myTextView setFrame:tempFrame];
Subclass UITextView, to a class of your own, let's say MyUITextView:UITextView.
Initialize it offscreen with
[[MyUITextView alloc] initWithFrame:CGRectZero]
In MyUITextView override the method
-(void)willMoveToWindow:(UIWindow *)newWindow
and in it, set self.frame to the proper value.
this worked for me!
Are you sure the text color is black? Also make sure that the image is behind the textView in the view hierarchy. TextView handles Word wrap automatically.
I think in this case, the viewDidLoad is getting called before modelViewController is presented.
Set the text after modalViewController is presented.
If that also not working, then after presenting model, call a method to set the text explicitly.
Check your view hierarchy. You might have added another textView above that view.
Try changing the background color of textView. It must appear is UITextView is added there. And make sure you are not adding another view as a subview above your UITextView. If the textColor is black it must be visible, wordwrap is done by default automatically unless you change the property.Also try to check the attributes settings in XIB if added and plz show the code if adding programmatically.
I think problem in:
self.view
Try add this code line at top
self.view = [[[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds] autorelease];
And if not will help, try remove this code line
myTextView.layer.cornerRadius = 5;
