iOS: Styling multiple textfields - objective-c

Question

I have multiple UITextFields with the same/similar styling but I'm styling them individually. How would I style them all in on go?
example of what I'm doing now:
textfield1.layer.borderWith = 2;
textfield2.layer.borderWith = 2;
textfield3.layer.borderWith = 2;

Answer 1

Here's something I've used in the past:
UITextField * textField1;
UITextField * textField2;
UITextField * textField3;
for (UITextField * textField in #[textField1, textField2, textField3]) {
textField.layer.borderWidth = 2;
}
If you're doing extensive edits to create a highly customized textField, it might be better to use a subclass. If you've just got a few additions you want applied to each textfield, this should be fine.
As per your request, because I'm feeling generous. Here's an example of a UITextField subclass.
MyTextField.h
#import <UIKit/UIKit.h>
#interface MyTextField : UITextField
#end
MyTextField.m
#import "MyTextField.h"
#implementation MyTextField
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
self.layer.borderWidth = 2;
// Blue For Demonstration
self.layer.borderColor = [UIColor blueColor].CGColor;
// add whatever else you want to customize here ....
}
return self;
}
////////
////// ** Include Custom Methods You Might Need **
////////
#end
Then, in whatever ViewController or View you want to use it, add this:
#import "MyTextField.h"
Then, you can launch MyTextField class Textfields like this:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
MyTextField * textField1 = [MyTextField new];
textField1.frame = CGRectMake(10, 30, 100, 30);
[self.view addSubview:textField1];
MyTextField * textField2 = [MyTextField new];
textField2.frame = CGRectMake(10, 70, 100, 30);
[self.view addSubview:textField2];
MyTextField * textField3 = [MyTextField new];
textField3.frame = CGRectMake(10, 110, 100, 30);
[self.view addSubview:textField3];
}
And you'll get this:

How about --
for (UIView *view in [self.view subviews]) {
if ([view isKindOfClass:[UITextField class]]) {
UITextField *textField = (UITextField *)view;
textField.layer.borderWidth = 2.0;
}
}
That way you will not even have to have outlets of textFields in the view. But this is, of course, only applicable if you want to apply same styles to every textField in the view.

If the textfields have outlets, create an IBOutletCollection like so in your .h:
#property (strong, nonatomic) IBOutletCollection(UITextField) NSArray *textFields;
Then, in your .m:
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
for(UITextField *textField in self.textFields) {
textfield.layer.borderWith = 2;
// add more here as needed
}
}
