今天寫(xiě)道需要選取照片(可以拍照或者選取圖庫(kù)的),不廢話,上代碼
這個(gè)是點(diǎn)擊事件
<code>
//提交選項(xiàng)
-(void)sendDataAction:(UIButton *) button{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"拍照", @"從相冊(cè)選擇", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:self.view];
}
//這里做個(gè)判斷
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0) {
[self toCameraPickingController];
}
else if (buttonIndex == 1) {
[self toPhotoPickingController];
}
}
//相機(jī)判斷
-
(void)toCameraPickingController
{
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
NSLog(@"Error:沒(méi)有照相設(shè)備");
}
else {
UIImagePickerController *cameraPicker = [[UIImagePickerController alloc] init];
cameraPicker.delegate = self;
cameraPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]) {
[self presentViewController:cameraPicker animated:YES completion:nil];
}
else {
// [self presentModalViewController:cameraPicker animated:YES];這個(gè)是找的demo里面的,這個(gè)方法過(guò)時(shí)了,被下面的替代了
[self presentViewController:cameraPicker animated:YES completion:nil];} [_sendDataButt setTitle:@"已上傳" forState:UIControlStateNormal];}
}
//圖庫(kù)判斷 -
(void)toPhotoPickingController
{
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
NSLog(@"Error:無(wú)圖片庫(kù)");
}
else {
UIImagePickerController *photoPicker = [[UIImagePickerController alloc] init];
photoPicker.delegate = self;
photoPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]) {
[self presentViewController:photoPicker animated:YES completion:nil];
}
else {
// [self presentModalViewController:photoPicker animated:YES];這個(gè)是找的demo里面的,這個(gè)方法過(guò)時(shí)了,被下面的替代了
[self presentViewController:photoPicker animated:YES completion:nil];
}
[_sendDataButt setTitle:@"已上傳" forState:UIControlStateNormal];}
}
pragma mark UIImagePickerControllerDelegate Methods
//圖片選擇
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
if ([self respondsToSelector:@selector(dismissViewControllerAnimated:completion:)]) {
[picker dismissViewControllerAnimated:YES completion:nil];
}
else {
//[picker dismissModalViewControllerAnimated:YES];這個(gè)是找的demo里面的,這個(gè)方法過(guò)時(shí)了,被下面的替代了
[self dismissViewControllerAnimated:YES completion:nil];
}
UIImage *imagePicked = [info objectForKey:UIImagePickerControllerOriginalImage];
_sendImage.image = imagePicked;
}
pragma mark UIImagePickerControllerDelegate Cancel Methods
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
//[picker dismissModalViewControllerAnimated:YES];這個(gè)是找的demo里面的,這個(gè)方法過(guò)時(shí)了,被下面的替代了
[self dismissViewControllerAnimated:YES completion:nil];
}
//設(shè)置一下屏幕 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
</code>
<code>
補(bǔ)充一下,攜帶參數(shù)上傳
-
(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSLog(@"圖片選中");
//截取圖片
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *imageData = UIImageJPEGRepresentation(image, 0.001);
self.mv.portraitImageView.image = image;AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",@"text/plain", nil nil];
// 參數(shù)
NSMutableDictionary *parameter = [NSMutableDictionary dictionary];
parameter[@"token"] = "param....";
// 訪問(wèn)路徑
NSString *stringURL = [NSString stringWithFormat:@"%@%@",HOSTURL,kUploadAvatar];[manager POST:stringURL parameters:parameter constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
// 上傳文件
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyyMMddHHmmss";
NSString *str = [formatter stringFromDate:[NSDate date]];
NSString *fileName = [NSString stringWithFormat:@"%@.jpg", str];[formData appendPartWithFileData:imageData name:@"file" fileName:fileName mimeType:@"image/png"];} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"上傳成功");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"上傳錯(cuò)誤");
}];
}
</code>
