Dialog like Xcode in OS X - macos

Question

I want to show the dialog with text input as sheet below.
I try with NSAlert but i don't want to show app icon in dialog.
NSAlert *alert = [[NSAlert alloc] init];
[alert setMessageText:kAppTitle];
[alert setInformativeText:kMsgSetDeviceName];
[alert addButtonWithTitle:kButtonOK];
[alert addButtonWithTitle:kButtonCancel];
NSString *deviceName = #"";
NSTextField *input = [[NSTextField alloc] initWithFrame:NSMakeRect(0, 0, 300, 24)];
[input setStringValue:deviceName];
[alert setAccessoryView:input];
[alert beginSheetModalForWindow:self.view.window completionHandler:^(NSInteger button) {
}];

You can use http://www.knowstack.com/nsalert-cocoa-objective-c/ link to create custom alert sheet in OSX.
-(void)showCustomSheet
{
{
if (!_customSheet)
//Check the myCustomSheet instance variable to make sure the custom sheet does not already exist.
[NSBundle loadNibNamed: #"CustomSheet" owner: self];
[NSApp beginSheet: self.customSheet
modalForWindow: self.window
modalDelegate: self
didEndSelector: #selector(didEndSheet:returnCode:contextInfo:)
contextInfo: nil];
// Sheet is up here.
}
}
- (IBAction)closeMyCustomSheet: (id)sender
{
[NSApp endSheet:_customSheet];
}
- (void)didEndSheet:(NSWindow *)sheet returnCode:(NSInteger)returnCode contextInfo:(void *)contextInfo
{
NSLog(#"%s",__func__);
NSLog(#"return Code %d",returnCode);
[sheet orderOut:self];
}
The below method is required to have a different point to show the alert from
- (NSRect)window:(NSWindow *)window willPositionSheet:(NSWindow *)sheet
usingRect:(NSRect)rect
{
NSLog(#"%s",__func__);
if (sheet == self.customSheet)
{
NSLog(#"if block");
NSRect fieldRect = [self.showAlertButton frame];
fieldRect.size.height = 0;
return fieldRect;
}
else
{
NSLog(#"else block");
return rect;
}
}
