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
{

break;
}
if (![UIImagePickerController isSourceTypeAvailable:sourceType]) {

return;
}
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;

[self presentViewController:imagePickerController animated:YES completion:NULL];
}
- (void)initalizerAlertViewWithTitle:(NSString *)title description:(NSString *)description
{

[alertView show];
}
- (void)showAvatarImage:(UITapGestureRecognizer *)tapGesture
{

}
#pragma mark - 图片选择控制器的代理
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

[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];

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"];
}];
}
ios 开发选取头像，图片库，相机，裁取图片
