1、调用相机、相册、图库
1 #import "ViewController.h"
2 #import <MobileCoreServices/MobileCoreServices.h>
3 #import <AVFoundation/AVFoundation.h>
4 #import <MediaPlayer/MediaPlayer.h>

6
7 @interface ViewController ()<UIImagePickerControllerDelegate,UINavigationControllerDelegate>
8 {
9 BOOL canmerIsOK;
10 BOOL photoLibaryIsOk;
11 BOOL photosAlbumIsOk;
12 UIImagePickerController *_imagePickerController;
13 }
14
15 @property (weak, nonatomic) IBOutlet UIImageView *imageView;
16
17 @end
18
19 @implementation ViewController
20 - (IBAction)showImagePickerView:(id)sender {
21 //NSLog(@"相册");
22 _imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
23
24 [self presentViewController:_imagePickerController animated:YES completion:nil];
25
26 }
27 - (IBAction)useCamera:(id)sender {
28 _imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
29 //录制视频时长，默认10s
30 _imagePickerController.videoMaximumDuration = 15;
31
32 //相机类型（拍照、录像...）字符串需要做相应的类型转换
33 _imagePickerController.mediaTypes = @[(NSString *)kUTTypeMovie,(NSString *)kUTTypeImage];
34
35 //视频上传质量
36 //UIImagePickerControllerQualityTypeHigh高清
37 //UIImagePickerControllerQualityTypeMedium中等质量
38 //UIImagePickerControllerQualityTypeLow低质量
39 //UIImagePickerControllerQualityType640x480
40 _imagePickerController.videoQuality = UIImagePickerControllerQualityTypeHigh;
41
42 //设置摄像头模式（拍照，录制视频）为录像模式
43 _imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
44 [self presentViewController:_imagePickerController animated:YES completion:nil];
45
46
47 }
48
49 - (void)viewDidLoad {
50 [super viewDidLoad];
51
52 _imagePickerController = [[UIImagePickerController alloc] init];
53 _imagePickerController.delegate = self;
54 _imagePickerController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
55 _imagePickerController.allowsEditing = YES;
56
57
58
59
60 // Do any additional setup after loading the view, typically from a nib.
61 }
62
63 #pragma mark UIImagePickerControllerDelegate
64 //该代理方法仅适用于只选取图片时
65 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(nullable NSDictionary<NSString *,id> *)editingInfo {
66 NSLog(@"选择完毕----image:%@-----info:%@",image,editingInfo);
67 }
68
69
70 //适用获取所有媒体资源，只需判断资源类型
71 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
72 NSString *mediaType=[info objectForKey:UIImagePickerControllerMediaType];
73 //判断资源类型
74 if ([mediaType isEqualToString:(NSString *)kUTTypeImage]){
75 //如果是图片
76 self.imageView.image = info[UIImagePickerControllerEditedImage];
77 //压缩图片
78 NSData *fileData = UIImageJPEGRepresentation(self.imageView.image, 1.0);
79 //保存图片至相册
80 UIImageWriteToSavedPhotosAlbum(self.imageView.image, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
81 //上传图片
82 // [self uploadImageWithData:fileData];
83
84 }else{
85 //如果是视频
86 NSURL *url = info[UIImagePickerControllerMediaURL];
87 //播放视频
88 // _moviePlayer.contentURL = url;
89 // [_moviePlayer play];
90 //保存视频至相册（异步线程）
91 NSString *urlStr = [url path];
92
93 dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
94 if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(urlStr)) {
95
96 UISaveVideoAtPathToSavedPhotosAlbum(urlStr, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);
97 }
98 });
99 NSData *videoData = [NSData dataWithContentsOfURL:url];
100 //视频上传
101 // [self uploadVideoWithData:videoData];
102 }
103 [self dismissViewControllerAnimated:YES completion:nil];
104 }
105
106
107 #pragma mark 图片保存完毕的回调
108 - (void) image: (UIImage *) image didFinishSavingWithError:(NSError *) error contextInfo: (void *)contextInf{
109
110 }
111
112 #pragma mark 视频保存完毕的回调
113 - (void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInf{
114 if (error) {
115 NSLog(@"保存视频过程中发生错误，错误信息:%@",error.localizedDescription);
116 }else{
117 NSLog(@"视频保存成功.");
118 }
119 }
2、调用iBook
需求调试条件：（iOS4.0 later）
1 1NSString *fileToOpen = [[NSBundle mainBundle] pathForResource:@"readme" ofType:@"pdf"]; 2 NSURL *url = [NSURL fileURLWithPath:fileToOpen]; 3 docController = [[UIDocumentInteractionController interactionControllerWithURL:url] retain]; 4 BOOL isValid = [docController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
3、打开word、execl、pdf等文档
1 方法一：
2 用UIWebView就可以了
3 -(void)loadDocument:(NSString*)documentName inView:(UIWebView*)webView
4 {
5 NSString *path = [[NSBundle mainBundle] pathForResource:documentName ofType:nil];
6 NSURL *url = [NSURL fileURLWithPath:path];
7 NSURLRequest *request = [NSURLRequest requestWithURL:url];
8 [webView loadRequest:request];
9 }
10
11 // Calling -loadDocument:inView:
12 [self loadDocument:@"test.doc" inView:self.myWebview];
13
14
15 方法我也已经测试过了，希望对大家有帮助，
16
17
18 方法二：
19 下面方法是直接通过QLPreviewController打开文档
20
21 qlViewController = [[QLPreviewController alloc] init];
22 qlViewController.dataSource = self;
23 [self presentModalViewController:qlViewController animated:YES];
24
25
26 - (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller {
27 return 1;
28 }
29 - (id <QLPreviewItem>)previewController:(QLPreviewController *)controller
30 previewItemAtIndex:(NSInteger)index{
31 //-------------读文件
32 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
33 NSString *documentsDirectory = [paths objectAtIndex:0];
34 if (!documentsDirectory) {
35 NSLog(@"Documents directory not found!");//return ;
36 }
37 NSString *fileName=[NSString stringWithFormat:@"%@.%@",nameQ,extQ];
38 NSString *appFile = [documentsDirectory stringByAppendingPathComponent:fileName];
39 //-------------
40 NSURL *myQLDocument = [NSURL fileURLWithPath:appFile];
41 return myQLDocument;
42 }
