How can set right margin in UItextfield and also placeholder text? - iphone

Question

I tried to set the right side margin in UItextfield but I can't get success for this.
I tried below code:
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(1, 1, 60, 25) ];
[lbl setText:#"Partenza:"];
[lbl setFont:[UIFont fontWithName:#"Verdana" size:12]];
[lbl setTextColor:[UIColor grayColor]];
[lbl setTextAlignment:UITextAlignmentLeft];
txtFCarat.rightView = lbl;
txtFCarat.rightViewMode = UITextFieldViewModeAlways;
txtFCarat.delegate = self;
Please help me if any body have a solution for this!

Answer 1

You can override this below two methods
#implementation rightTextField
// placeholder position
- (CGRect)textRectForBounds:(CGRect)bounds {
return CGRectInset( self.bounds , margin position , margin position );
}
// text position
- (CGRect)editingRectForBounds:(CGRect)bounds {
return CGRectInset( self.bounds , margin position ,margin position );
}
Edit: use to bind code like
textField.bounds = [self editingRectForBounds:textField.bounds];
textField.bounds = [self textRectForBounds:textField.bounds];
Your expected Answer:
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"icon.png"]];
textfield.rightView = imageView;
textfield.rightViewMode = UITextFieldViewModeAlways;

Answer 2

Add the below line where you are creating textfield..and set value as per requirement
textField.layer.sublayerTransform = CATransform3DMakeTranslation(-20, 000, 0);
Another way to achieve this by overriding the textRectForBounds
Let me to give complete Description how to do this or achieve it
First you create a class and name "textField"(or what ever you Want) and must be sure that IT IS SUBCLASS OF UITextField.
2.Now open the textfield.m class and use this code or paste below code in this class (textfield):
- (CGRect)textRectForBounds:(CGRect)bounds {
return CGRectMake(bounds.origin.x + 50, bounds.origin.y,
bounds.size.width - 20, bounds.size.height);
}
-(CGRect)editingRectForBounds:(CGRect)bounds {
return [self textRectForBounds:bounds];
}
If you want to customize the textfield more then you can use here only or in calling Class like
use the below code :Note it is only for testing purpose.it depend on your requirement
- (void)settingTextField {
[self setTextField];
[self setKeyboardAppearance:UIKeyboardAppearanceAlert];
}
- (void)setTextField {
[self setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];
[self setContentVerticalAlignment:UIControlContentVerticalAlignmentCenter];
[self setTextAlignment:NSTextAlignmentCenter];
[self setValue:[UIColor colorWithRed:120.0/225.0 green:120.0/225.0 blue:120.0/225.0 alpha:1.0] forKeyPath:#"_placeholderLabel.textColor"];
[self setFont:[UIFont boldSystemFontOfSize:15.0f]];
}
3.improt textField.h class into your view-controller where you wants to create textfield
and you call it like this.
#import "textField.h"
//Viewcontroller Class
- (void)viewDidLoad
{
[super viewDidLoad];
textField *field1 = [[textField alloc] initWithFrame:CGRectMake(50, 50, 200, 20)];
field1.backgroundColor=[UIColor greenColor];
field1.placeholder=#"0";
[self.view addSubview:field1];
}
Try to adjust the value textRectForBounds as per you reqitement

NSString *myString = #"Partenza:";
UIFont *myFont = [UIFont fontWithName:#"Verdana" size:12];
CGSize myStringSize = [myString sizeWithFont:myFont];
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, myStringSize.width + 10, 25) ];
[lbl setText:myString];
[lbl setFont:[UIFont fontWithName:#"Verdana" size:12]];
[lbl setTextColor:[UIColor grayColor]];
[lbl setTextAlignment:UITextAlignmentLeft];
txtFCarat.rightView = lbl;
txtFCarat.rightViewMode = UITextFieldViewModeAlways;
