Uiview,uilabel,uitextfield,viewcontroller .....

However, none of the above is quite understood ...

Here's what you learned =w=

While the Baidu side learned. So many things come from other blogs. The back will post the source.

. Frame: The position of the control relative to the parent view

The style of the UITextField.borderStyle:UITextField

The. Text: The text that the control displays

. backgroundcolor: The background color of the control (however, setting this will invalidate certain properties of the control)

Uicolor: a color class ... And yet I don't understand

-Addsubview: (UIView *): Add a child view to the view

CGRectMake (<cgfloat x>, <cgfloat y>, <cgfloat width>, <cgfloat height>): The X, y offset and DX of the parameter relative to the parent view, Dy. Returns a CGRect value.

addtarget:< (ID) > action:< (SEL) > forcontrolevents:< (uicontrolevents) >: The object that performs the action, the function that executes the action, And when to perform the action

[Button addtarget:self action: @selector (back:) forcontrolevents:uicontroleventtouchupinside];

↑↑↑↑ This is an example, in this viewcontroller (self), executes the back: This function, which is pressed and bounces within the space range, is a response

Here is a description of the various events http://blog.csdn.net/g5dsk/article/details/6613943

Resignfirstresponder: This can be used on Uitextfield to release the first response .... Can retract the keyboard

Uibarbutton: Buttons that can be added to the Navigationitem

pushviewcontroller:< (Uiviewcontroller *) > animated:< (BOOL) >: Launch a viewcontroller can be used to switch pages, Animated used to control whether or not to roll out animations

poptorootviewcontrolleranimated:< (BOOL);: Returns the view controller that called it. You can also choose to have no animations

/* Top is what I picked out this day to learn .... Here are some sample code that has not been collated */

    UIView *view = [[UIView alloc]init];    View.frame = CGRectMake (0, 0,.);    View.backgroundcolor = [Uicolor yellowcolor];    [Self.view Addsubview:view];
    UIView *view = [[UIView alloc]init];
    view.frame = CGRectMake(0, 0, 100, 100);
    view.backgroundColor = [UIColor yellowColor];
    [self.view addSubview:view];


    UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
    button.frame = CGRectMake(100, 100, 100, 100);
    button.backgroundColor = [UIColor blueColor];
    [button addTarget:self action:@selector(push) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button]
-(void)push{
    FirstViewController *first = [[FirstViewController alloc] init];
    [self.navigationController pushViewController:first animated:YES];
}
