you can Creat UITextField, UIButton or UILabel like this bellow code:-
UITextField
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 200, 300, 40)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.font = [UIFont systemFontOfSize:15];
textField.placeholder = #"enter text";
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.keyboardType = UIKeyboardTypeDefault;
textField.returnKeyType = UIReturnKeyDone;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
textField.delegate = self;
[self.view addSubview:textField];
[textField release];
UIButton
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(aMethod:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"UIButton" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];
[button release];
UILabel
UILabel *headingLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 240, 300, 30)];
[self.view addSubview:headingLabel];
// Optional
headingLabel.text = #"WELCOME";
headingLabel.textColor = [UIColor orangeColor];
headingLabel.textAlignment = UITextAlignmentCenter;
headingLabel.tag = 10;
headingLabel.backgroundColor = [UIColor clearColor];
headingLabel.font = [UIFont fontWithName:#"MarkerFelt-Thin" size:14.0];
headingLabel.hidden = NO;
headingLabel.highlighted = YES;
headingLabel.highlightedTextColor = [UIColor blueColor];
headingLabel.lineBreakMode = YES;
headingLabel.numberOfLines = 0;
UIImageView
UIImageView *myImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 150, 150)];
myImage.image = [UIImage imageNamed:#"myImage.png"];
[self.view addSubview:myImage];
