我正在研究 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 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 https://developers.google.com/identity/sign-in/ios/api/interface_g_i_d_profile_data#a8e229bffe211894473058c4ba247553c），可以这样获取用户图像 url：
但是，当我尝试获取尺寸为（120）的图像 URL 时，应用程序总是崩溃。我为此苦恼了半天，还是不知道为什么。 任何人都可以帮助我。非常感谢。
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：

And it says signIn.currentUser.profile.imageURLWithDimension(120) is invalid expression:
对于目标 C ：
if (user.profile.hasImage)
{
NSURL *url = [user.profile imageURLWithDimension:100];
NSLog(@"url : %@",url);
}
对于斯威夫特：
if user.profile.hasImage
{
let pic = user.profile.imageURLWithDimension(100)
Print(pic)
}
注：100为尺寸。这取决于您的要求。
