ios google登录,如何获取用户图片网址？

概述我正在iOS / Swift谷歌登录.我在github上做了一个demo. 我的演示项目： https://github.com/tanggod/GoogleSignIn.git 根据谷歌(https://developers.google.com/identity/sign-in/ios/api/interface_g_i_d_profile_data#a8e229bffe21189447305 我正在iOS / Swift谷歌登录.我在github上做了一个demo.
我的演示项目： https://github.com/tanggod/GoogleSignIn.git

根据谷歌(https://developers.google.com/identity/sign-in/ios/api/interface_g_i_d_profile_data#a8e229bffe211894473058c4ba247553c),用户图像网址可以像这样获取：

>(NSURL *)imageURLWithDimension：(NSUInteger)维度
获取方块每一侧的给定维度的用户配置文件图像URL(以像素为单位).

但是,当我尝试获取imageURLWithDimension(120)时,应用程序总是崩溃.我一直在为此奋斗半天,但仍然不知道为什么.
任何人都可以帮助我.非常感谢你.

func signIn(signIn: GIDSignIn!,dIDSignInForUser user: GIDGoogleUser!,withError error: NSError!) {    print("=== UIVIEwController sign in")    if (error == nil) {        // Perform any operations on signed in user here.        let userID = user.userID                  // For clIEnt-sIDe use only!        //let IDToken = user.authentication.IDToken // Safe to send to the server        let name = user.profile.name        let email = user.profile.email        if user.profile.hasImage{            // crash here !!!!!!!! cannot get imageUrl here,why?            // let imageUrl = user.profile.imageURLWithDimension(120)            let imageUrl = signIn.currentUser.profile.imageURLWithDimension(120)            print(" image url: ",imageUrl.absoluteString)        }        // ...        print(" userID: ",userID)        //            print(" IDToken: ",IDToken)        print(" name: ",name)        print(" email: ",email)        labelname.text = name        labelEmail.text = email    } else {        print("\(error.localizedDescription)")    }}

崩溃数据如下：

并且它表示signIn.currentUser.profile.imageURLWithDimension(120)是无效的表达式：

解决方法 正如@ajmccall所说,错字！

但您可以按类别NSURL解决此问题.

新的Objective-C类：

NSURL file.h

#import <Foundation/Foundation.h>@interface NSURL (file)- (BOol) isFIFEUrl;@end

NSURL file.m

导入“NSURL file.h”

@implementation  NSURL (file)- (BOol) isFIFEUrl {    return [self isfileURL];}@end
