Add lefthand margin to UITextField

You can do it by extending UITextField class and overriding two methods:

- (CGRect)textRectForBounds:(CGRect)bounds;- (CGRect)editingRectForBounds:(CGRect)bounds;

Here is the code:

The interface in MYTextField.h

@interface MYTextField : UITextField@end

Its implementation in MYTextField.m

@implementation MYTextFieldstatic CGFloat leftMargin = 28; - (CGRect)textRectForBounds:(CGRect)bounds{    bounds.origin.x += leftMargin;    return bounds;} - (CGRect)editingRectForBounds:(CGRect)bounds{    bounds.origin.x += leftMargin;    return bounds;}@end

As I have explained in a previous comment, the best solution in this case is to extend the UITextField class instead of using a category, so you can use it explicitly on the desired text fields.

#import <UIKit/UIKit.h>@interface MYTextField : UITextField@end@implementation MYTextField- (CGRect)textRectForBounds:(CGRect)bounds {    int margin = 10;    CGRect inset = CGRectMake(bounds.origin.x + margin, bounds.origin.y, bounds.size.width - margin, bounds.size.height);    return inset;}- (CGRect)editingRectForBounds:(CGRect)bounds {    int margin = 10;    CGRect inset = CGRectMake(bounds.origin.x + margin, bounds.origin.y, bounds.size.width - margin, bounds.size.height);    return inset;}@end

A category is intended to add new functions to an existing class, not to override an existing method.

UITextField * textField = [[UITextField alloc]init];[textField setDelegate:self];[textField setFrame:CGRectMake(170,112,140,25)];[textField setBorderStyle:UITextBorderStyleNone];[textField setBackgroundColor:[UIColor clearColor]];[self.View addSubview:noofChildTField];UIView *paddingView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 20)] autorelease];textField.leftView = paddingView;textField.leftViewMode = UITextFieldViewModeAlways;
