UITextField background Issue.

Hi,

This is what my code.

- (void) viewDidLoad {

[super viewDidLoad];

UIImage *image = [UIImageimageNamed:@"btn_facebook.png"];

image = [image resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 1, 0)];

txtEmailId = [[UITextFieldalloc] initWithFrame:CGRectMake(10, 30, 300, 44)];

[txtEmailIdsetDelegate:self];

[txtEmailIdsetBorderStyle:UITextBorderStyleNone];

[txtEmailId setBackground:image];

[txtEmailIdsetDisabledBackground:image];

[txtEmailIdsetFont:[UIFontfontWithName:@"HelveticaNeue"size:16]];

[txtEmailIdsetContentVerticalAlignment:UIControlContentVerticalAlignmentCenter];

[txtEmailIdsetClearButtonMode:UITextFieldViewModeWhileEditing];

[txtEmailIdsetAutocapitalizationType:UITextAutocapitalizationTypeNone];

[txtEmailIdsetAutocorrectionType:UITextAutocorrectionTypeNo];

[txtEmailIdsetReturnKeyType:UIReturnKeyNext];

[[selfview] addSubview:txtEmailId];

}

- (void) textFieldDidBeginEditing:(UITextField *)textField {

[txtEmailIdsetBackground:nil];

}

- (void)textFieldDidEndEditing:(UITextField *)textField {

UIImage *image = [UIImage imageNamed:@"btn_line.png"];

image = [image resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 1, 0)];

[txtEmailId setBackground:image];

}
