Customize UITextfield of the UISearchbar - iOS

I'm trying to customize the textfield for the UISearchbar. The picture below shows my half done work.
strong text

I have subclasses the UISearchbar and called it from my view controller. I'm trying to remove those dark gray lines from the textfield. Below is the implementation of the UISearchbar adding to subview of the viewcontroller.

searchbar = [[SearchBar alloc] initWithFrame:CGRectMake(35,78, 250, 17)];
searchbar.backgroundColor = [UIColor clearColor];
searchbar.layer.borderColor = [[UIColor clearColor] CGColor];
searchbar.layer.borderWidth = 0;

for(UIView *view in searchbar.subviews){
if([view isKindOfClass:[UITextField class]]){
UITextField *tf= (UITextField *)view;
tf.layer.borderColor = [[UIColor clearColor] CGColor];
tf.delegate = self;
[self.view addSubview:searchbar];
searchbar.delegate = self;

UISearchBar subclass:

- (id)initWithFrame:(CGRect)frame
self = [super initWithFrame:frame];
if (self) {
// Initialization code
return self;

UITextField *searchField;
[[[self subviews] objectAtIndex:0] removeFromSuperview];
[self setTintColor:[UIColor clearColor]];
self.clipsToBounds = YES;
NSUInteger numViews = [self.subviews count];
for(int i = 0; i < numViews; i++) {
if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) {
searchField = [self.subviews objectAtIndex:i];
searchField.leftViewMode = UITextFieldViewModeNever;
searchField.backgroundColor = [UIColor clearColor];


if(!(searchField == nil)) {
searchField.backgroundColor = [UIColor clearColor];
searchField.textColor = [UIColor blackColor];
searchField.frame = CGRectMake(self.frame.origin.x,self.frame.origin.y,self.frame.size.width,self.frame.size.height-10);

[searchField setBorderStyle:UITextBorderStyleRoundedRect];


[super layoutSubviews];


I'm trying to achive something like this:
The textfield should not have any boundaries. The icons are flattened UIImageView.

This is an easy way to get textfield from UISearchBar subview hierarchy and set its properties as needed like

  UITextField *txfSearchField = [searchbar valueForKey:@"_searchField"];
[txfSearchField setBackgroundColor:[UIColor whiteColor]];
    [txfSearchField setLeftView:UITextFieldViewModeNever];
    [txfSearchField setBorderStyle:UITextBorderStyleRoundedRect];
    txfSearchField.layer.borderWidth = 8.0f; 
    txfSearchField.layer.cornerRadius = 10.0f;
        txfSearchField.layer.borderColor = [UIColor clearColor].CGColor;
