1. 二维码
iOS7之前使用第三番 Z-Xing Z-Bar
iOS7之后系统提供原生方式
-
二维码的生成,通过一定的规则把数据转换成图片
//1.创建一个种类的滤镜
***二维码
CIFilter *filter = [CIFilter filterWithName:@"CIQRCodeGenerator"];
***条形码
CIFilter *filter1 = [CIFilter filterWithName:@"CICode128BarcodeGenerator"];
//2.恢复滤镜的默认设置(清除已经设置过的效果)
[filter setDefaults];
//3.将隐藏的地址变成二进制数据
NSData *data = [@"http://www.baidu.com" dataUsingEncoding:NSUTF8StringEncoding];
//4.通过KVC的方式设置滤镜,传入要隐藏的data
//滤镜就能够依据data生成二维码
[filter setValue:data forKey:@"inputMessage"];
//5.输出二维码图片
CIImage *outputImage = [filter outputImage];
//6.将CIImage转换成UIImage
UIImage *image = [UIImage imageWithCIImage:outputImage];
//7.显示
self.imageView.image = image;
- 扫描二维码
1. 打开后置摄像头
2. 从后置摄像头中读取数据输入流
3. 把输入流输出到屏幕上---输出流
4. 把输入流和输出流连接起来---管道session
5. 让输出流实时过滤数据,监听是否有二维码(条形码)如果有就通过协议通知我们
import "ViewController.h"
import <AVFoundation/AVFoundation.h>
@interface ViewController ()<AVCaptureMetadataOutputObjectsDelegate>
- (IBAction)startScan:(id)sender;
/** 连接输入输出流的对象/
@property (nonatomic,strong)AVCaptureSession * session;
/* 用于展示输出流的对象*/
@property (nonatomic,strong)AVCaptureVideoPreviewLayer * videoLayer;
@end
@implementation ViewController
-
(void)viewDidLoad {
[super viewDidLoad];
} -
(IBAction)startScan:(id)sender {
//1.获取后置摄像头管理对象
AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
//2.获取输入流
NSError *error = nil;
AVCaptureDeviceInput *input = [AVCaptureDeviceInput deviceInputWithDevice:device error:&error];
if (error) {
NSLog(@"%@",error);
}
//3.创建输出流 (把图像显示)
AVCaptureMetadataOutput *output = [AVCaptureMetadataOutput new];
//设置代理
[output setMetadataObjectsDelegate:self queue:dispatch_get_main_queue()];//4.构建连接通道
_session = [AVCaptureSession new];
[_session addInput:input];
[_session addOutput:output];//5.通道质量设置(流畅 高清 标清)
[_session setSessionPreset:AVCaptureSessionPresetHigh];//6.设置输出流的类型(二维码 条形码...)一定要在通道连接之后设置,否则不起作用
output.metadataObjectTypes = @[AVMetadataObjectTypeQRCode,AVMetadataObjectTypeCode128Code,AVMetadataObjectTypeEAN8Code,AVMetadataObjectTypeEAN13Code];//7.显示
_videoLayer = [AVCaptureVideoPreviewLayer layerWithSession:_session];
_videoLayer.frame = self.view.bounds;[self.view.layer addSublayer:_videoLayer];
//8.启动通道
[self.session startRunning];
}
pragma mark -AVCaptureMetadataOutputObjectsDelegate
//当扫描到数据时
-(void)captureOutput:(AVCaptureOutput *)captureOutput didOutputMetadataObjects:(NSArray *)metadataObjects fromConnection:(AVCaptureConnection *)connection{
if (metadataObjects.count > 0) {
[_session stopRunning];
[_videoLayer removeFromSuperlayer];
//拿出扫描数据
AVMetadataMachineReadableCodeObject *object = metadataObjects.firstObject;
NSLog(@"扫描到的数据是:%@",[object stringValue]);
}
}```
2. 摇一摇
- 1 开始摇一摇
-(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event - 2 结束摇一摇
-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event - 3 取消摇一摇(被中断,例如:来电)
-(void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
3. 社会化分享
- 4.1 分享到各方平台。例如:分享到新浪微博->第三方登录->分享
- 4.2 系统自带的分享
->iOS6之后集成新浪微博
->iOS7之后支持腾讯微博
#import "ViewController.h"
#import <Social/Social.h>
@interface ViewController ()
@end
@implementation ViewController
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
if (![SLComposeViewController isAvailableForServiceType:SLServiceTypeSinaWeibo]) {
NSLog(@"不支持新浪微博");
}
//1.创建类型
SLComposeViewController *cvc = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeSinaWeibo];
//2.设置数据
[cvc setInitialText:@"潮湿的不得了"];
[cvc addImage:[UIImage imageNamed:@"icon"]];
//3.显示
[self presentViewController:cvc animated:YES completion:nil];
//4.监听
cvc.completionHandler = ^(SLComposeViewControllerResult result){
if (result == SLComposeViewControllerResultDone) {
NSLog(@"发布成功");
}else{
NSLog(@"发布失败");
}
};
}

- 1 注册并登陆
- 2 新建应用获得appkey
- 3 找到官方的Apple平台集成文档
如果运行在真机,程序崩溃 出现bitcode
Target -> Build Setting ->修改BitCode```
