UIView display a color-colored view

UIView *view = [[UIView alloc]init];

View.frame = CGRectMake (100, 100, 300, 300);

[Self.window Addsubview:view];

View.backgroundcolor = [Uicolor Orangecolor];

Uilable Label control, suitable for putting some short text.

Uilable inherited from UIView

Instantiate the Lable object, and any object must be instantiated

UILabel * lable = [[UILabel alloc]init];

Set frame for lable

Lable.frame = CGRectMake (200, 200, 200, 200);

Set Text to Uilable

Lable.text = @ "Zkysdfdsghhhjjghjkgiu";

Lable.textcolor = [Uicolor Whitecolor];

To set the alignment for uilable:

Lable.textalignment =nstextalignmentnatural;

Uifont Uicolor are classes that need to be instantiated as objects they create.

Font size

Lable.font = [Uifont systemfontofsize:25];

Bold font also sets the size of the font

Lable.font = [Uifont boldsystemfontofsize:26];

Font size is also set when italic is set

Lable.font = [Uifont italicsystemfontofsize:28];

Set shadow and set shadow color

Lable.shadowcolor = [Uicolor Bluecolor];

Set the shadow offset

Lable.shadowoffset = Cgsizemake (6, 6);

Set the number of rows to the content, 0 for the adaptive row count, not 0 for a few rows

Lable.numberoflines = 0;

Self-adapting fonts to make content appear as one line

Lable.adjustsfontsizetofitwidth = YES;

Lable.backgroundcolor = [Uicolor Redcolor];

[Self.window addsubview:lable];

Set Imgview display Picture

Uiimageview *imgview =[[uiimageview Alloc]init];

If the picture is in PNG format, the picture does not need to be suffixed, otherwise it must be added

Imgview.image = [UIImage imagenamed:@ "Boy1.tiff"];

Imgview.frame = CGRectMake (10, 10, 300, 200);

[Self.window Addsubview:imgview];

/*

* Create three elements of frame animation

* 1, set the interval time

* 2, prepare the picture material

* 3, set the number of repetitions

* 4, start animation

*/

Animationduration to set the animation time interval

Imgview.animationduration = 1;

Put the instantiated object into the array

UIImage * img1=[uiimage imagenamed:@ "Boy1.tiff"];

UIImage * img2=[uiimage imagenamed:@ "Boy2.tiff"];

UIImage * img3=[uiimage imagenamed:@ "Boy3.tiff"];

UIImage * img4=[uiimage imagenamed:@ "Boy4.tiff"];

UIImage * img8=[uiimage imagenamed:@ "Boy8.tiff"];

Nsarray * array = @[img1,img2,img3,img4,img5,img6,img7,img8];

Animationimages preparing footage for frame animations

Imgview.animationimages =array;

RepeatCount set Number of repetitions

Imgview.animationrepeatcount = 50;

Start animation

[Imgview startanimating];

End Animation
