IOS Integrated Technology

1. Hide the status bar [[uiapplication sharedapplication] setstatusbarhidden: Yes animated: No];

2. Open the mobile album

First, introduce the uiimagepickercontrollerdelegate protocol.

Uiimagepickercontroller * imgpickercontroller = [[uiimagepickercontrolleralloc] init];

Imgpickercontroller. Delegate = self;

Imgpickercontroller. sourcetype = uiimagepickercontrollersourcetypephotolibrary;

[Selfpresentviewcontroller: Self. imgpickercontrolleranimated: yescompletion: Nil];

3. Identify and display the running device type

Nsstring * devicetype = [uidevicecurrentdevice]. model;

Nslog (@ "current device type: % @", devicetype );

4. Number on the tabbar Image

Self. tabbaritem. badgevalue = [nsstringstringwithformat: @ "% d", 9];

5. Remove the lines between cells from tableview.

Mytableview. separatorstyle = uitableviewcellseparatorstylenone;

6. Load local file PDF

Nsurl * url = [[nsbundle mainbundle] urlforresource: @ "sample" withextension: @ "pdf"];

7.

Uitapgesturerecognizer * singletap = [[uitapgesturerecognizeralloc] initwithtarget: selfaction: @ selector (btnimageview :)];

[Self. imageviewaddgesturerecognizer: singletap];

-(Void) btnimageview :( ID) sender {

Cabasicanimation * Shake = [cabasicanimationanimationwithkeypath: @ "transform. Rotation. Z"];

// Set the jitter Amplitude

Shake. fromvalue = [nsnumbernumberwithfloat:-0.1];

Shake. tovalue = [nsnumbernumberwithfloat: + 0.1];

Shake. Duration = 0.1;

Shake. autoreverses = yes; // whether it is repeated

Shake. repeatcount = 4;

[Self. imageview. layeraddanimation: shakeforkey: @ "imageview"];

Self. imageview. Alpha = 1.0;

[Uiviewanimatewithduration: 2.0 delay: 2.0 options: uiviewanimationoptioncurveeaseinanimations: nilcompletion: Nil];

}

8.

// Set the background of uitableview to transparent

Table. backgroundview = nil;

Table. backgroundcolor = [uicolor clearcolor];

Table. opaque = no;

9.

To display a uiview at the beginning, you only need to call the bringsubviewtofront () method of its parent view.

To push a uiview layer to the backend, you only need to call the sendsubviewtoback () method of its parent view.
