NSTextAlignmentCenter not work with custom text field - ios

Question

I was subclassing UITextField to make my custom text field.
I used self.textAlignment = NSTextAlignmentCenter; to set the text alignment, but when I began editing, the cursor's initial position was left rather than exactly the center. Hoever, when I entered something, the text was in the center position.
textRectForBounds: and editingRectForBounds: all return the same CGRect value.
Here is the code:
#interface MyTextfield () <UITextFieldDelegate>
#end
- (instancetype)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
self.delegate = self;
self.textAlignment = NSTextAlignmentCenter;
}
return self;
}
- (CGRect)textRectForBounds:(CGRect)bounds {
return CGRectInset(bounds, 20.5, 4.5);
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
return CGRectInset(bounds, 20.5, 4.5);
}
- (void)textFieldDidBeginEditing:(UITextField *)textField {
// Do some animation
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
// Do some animation
}
What's the problem? How can I fix it?

Answer 1

first of all create one UITextField class.
CustomTextfield.h
#import <UIKit/UIKit.h>
#interface CustomTextfield : UITextField
#end
CustomTextfield.m
#import "CustomTextfield.h"
#interface CustomTextfield () <UITextFieldDelegate>
#end
#implementation CustomTextfield
- (instancetype)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
self.textAlignment = NSTextAlignmentCenter;
self.font = [UIFont systemFontOfSize:15];
self.placeholder = #"Test";
self.autocorrectionType = UITextAutocorrectionTypeNo;
self.keyboardType = UIKeyboardTypeDefault;
self.returnKeyType = UIReturnKeyDone;
self.textAlignment = NSTextAlignmentCenter;
self.clearButtonMode = UITextFieldViewModeWhileEditing;
self.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
self.borderStyle=UITextBorderStyleRoundedRect;
}
return self;
}
- (CGRect)textRectForBounds:(CGRect)bounds {
return CGRectInset(bounds, 20.5, 4.5);
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
return CGRectInset(bounds, 20.5, 4.5);
}
Now use CustomTextfield class to your view controller like this.
-(void)viewDidLoad{
UITextField *txtEmailfield = [[CustomTextfield alloc] initWithFrame:CGRectMake(10, 200, 300, 40)];
txtEmailfield.delegate = self;
[self.view addSubview:txtEmailfield];
}
Note : In this view controller please add this in #interface yourviewcontroller name () <UITextFieldDelegate>
