ios打开照相机与本地相册选择图片

最近正好项目里面要集成“打开照相机与本地相册选择图片”的功能，今天就在这边给大家写一个演示程序；打开相机拍摄后或者在相册中选择一张照片，然后将它显示在界面上。好了废话不多说，因为比较简单直接上源码。

首先，我们在头文件中添加需要用到的actionsheet控件，显示图片的uiimageview控件，并且加上所需要的协议

? 1 2 3 4 5 6 7 8 9 10 #import <uikit/uikit.h> @interface imagepickerviewcontroller : uiviewcontroller<uiimagepickercontrollerdelegate,uiactionsheetdelegate,uinavigationcontrollerdelegate> @property (strong, nonatomic) iboutlet uiimageview *headimage; @property (strong, nonatomic) uiactionsheet *actionsheet; - (ibaction)clickpickimage:(id)sender; @end

通过点击我设置在界面中的按钮来呼出actionsheet控件，来选择相应的操作拍照或是在相册中选择相片，代码如下：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 // // imagepickerviewcontroller.m // testauto // // created by silicon on 15/5/9. // copyright (c) 2015年 silicon. all rights reserved. // #import "imagepickerviewcontroller.h" @interface imagepickerviewcontroller () @end @implementation imagepickerviewcontroller @synthesize actionsheet = _actionsheet; - (void)viewdidload { [super viewdidload]; // do any additional setup after loading the view from its nib. } - (void)didreceivememorywarning { [super didreceivememorywarning]; // dispose of any resources that can be recreated. } /** @ 调用actionsheet */ - (void)callactionsheetfunc{ if([uiimagepickercontroller issourcetypeavailable:uiimagepickercontrollersourcetypecamera]){ self.actionsheet = [[uiactionsheet alloc] initwithtitle:@"选择图像" delegate:self cancelbuttontitle:@"取消" destructivebuttontitle:nil otherbuttontitles:@"拍照", @"从相册选择", nil nil]; }else{ self.actionsheet = [[uiactionsheet alloc] initwithtitle:@"选择图像" delegate:self cancelbuttontitle:@"取消"destructivebuttontitle:nil otherbuttontitles:@"从相册选择", nil nil]; } self.actionsheet.tag = 1000; [self.actionsheet showinview:self.view]; } // called when a button is clicked. the view will be automatically dismissed after this call returns - (void)actionsheet:(uiactionsheet *)actionsheet clickedbuttonatindex:(nsinteger)buttonindex{ if (actionsheet.tag == 1000) { nsuinteger sourcetype = uiimagepickercontrollersourcetypephotolibrary; // 判断是否支持相机 if([uiimagepickercontroller issourcetypeavailable:uiimagepickercontrollersourcetypecamera]) { switch (buttonindex) { case 0: //来源:相机 sourcetype = uiimagepickercontrollersourcetypecamera; break; case 1: //来源:相册 sourcetype = uiimagepickercontrollersourcetypephotolibrary; break; case 2: return; } } else { if (buttonindex == 2) { return; } else { sourcetype = uiimagepickercontrollersourcetypesavedphotosalbum; } } // 跳转到相机或相册页面 uiimagepickercontroller *imagepickercontroller = [[uiimagepickercontroller alloc] init]; imagepickercontroller.delegate = self; imagepickercontroller.allowsediting = yes; imagepickercontroller.sourcetype = sourcetype; [self presentviewcontroller:imagepickercontroller animated:yes completion:^{ }]; } } - (void)imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info { [picker dismissviewcontrolleranimated:yes completion:^{ }]; uiimage *image = [info objectforkey:uiimagepickercontrolleroriginalimage]; self.headimage.image = image; } /* #pragma mark - navigation // in a storyboard-based application, you will often want to do a little preparation before navigation - (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender { // get the new view controller using [segue destinationviewcontroller]. // pass the selected object to the new view controller. } */ - (ibaction)clickpickimage:(id)sender { [self callactionsheetfunc]; } @end

代码比较简单，也容易理解，运行的效果如下：
