ios 开发选取头像，图片库，相机，裁取图片

需要遵守的代理协议：UIActionSheetDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate

@property (nonatomic, strong) UIActionSheet *avatarActionSheet;

第一步：点击头像cell需要做的事情

[self.avatarActionSheet showInView:self.view];

第二步：

#pragma mark - 点击头像

- (UIActionSheet *)avatarActionSheet

{

if (!_avatarActionSheet) {

_avatarActionSheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"选择你的头像", @"") delegate:self cancelButtonTitle:NSLocalizedString(@"取消", @"") destructiveButtonTitle:nil otherButtonTitles:NSLocalizedString(@"相机", @""), NSLocalizedString(@"在图片库选择", @""), nil];

}

return _avatarActionSheet;

}

#pragma mark - 弹框代理方法

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex

{

GYLog(@"%d" , buttonIndex);

if (buttonIndex == 2) return;// 取消

[self showImagePickerViewController:buttonIndex];

}

- (void)showImagePickerViewController:(NSInteger)pickerUserAvatarType

{

UIImagePickerControllerSourceType sourceType;

NSString *description = nil;

switch (pickerUserAvatarType) {

case 0:

sourceType = UIImagePickerControllerSourceTypeCamera;

description = NSLocalizedString(@"该设备不支持相机", @"");

break;

case 1:

sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

description = NSLocalizedString(@"该设备不支持图片库", @"");

break;

}

if (![UIImagePickerController isSourceTypeAvailable:sourceType]) {

[self initalizerAlertViewWithTitle:NSLocalizedString(@"警告", @"") description:description];

return;

}

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

imagePickerController.delegate = self;

imagePickerController.allowsEditing = YES;

imagePickerController.sourceType = sourceType;

imagePickerController.videoQuality = UIImagePickerControllerQualityTypeMedium;

[self presentViewController:imagePickerController animated:YES completion:NULL];

}

- (void)initalizerAlertViewWithTitle:(NSString *)title description:(NSString *)description

{

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title message:description delegate:nil cancelButtonTitle:nil otherButtonTitles: NSLocalizedString(@"确定", @""), nil];

[alertView show];

}

- (void)showAvatarImage:(UITapGestureRecognizer *)tapGesture

{

GYLog(@"----------------------");

}

#pragma mark - 图片选择控制器的代理

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

UIImage *userAvatar = [info valueForKey:UIImagePickerControllerEditedImage];

[self.userIconView setImage:userAvatar];

[picker dismissViewControllerAnimated:YES completion:NULL]；

// 1.创建请求管理对象

AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager];

// 2.封装请求参数

NSMutableDictionary *params = [NSMutableDictionary dictionary];

params[@"verify"] = [GYUserDefaults objectForKey:@"verify"];

params[@"avatar"] = userAvatar;

// 3.发送请求

NSString *str = [NSString stringWithFormat:@"http://%@/?action=personal&option=update_avatar",GYAPP_URL];

[mgr POST:str parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { // 在发送请求之前调用这个block

NSData *data = UIImageJPEGRepresentation(userAvatar, 0.000001);

[formData appendPartWithFileData:data name:@"pic" fileName:@"" mimeType:@"image/jpeg"];

} success:^(AFHTTPRequestOperation *operation, id responseObject) {

[MBProgressHUD showSuccess:@"发送成功"];

#warning 是否需要进行数据存储

[GYUserDefaults setObject:responseObject[@"avatar"] forKey:@"avatar"];

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

[MBProgressHUD showError:@"发送失败"];

}];

}
