如何自定义 Facebook 中的登录按钮？我不想使用 Facebook 默认登录按钮。
对于 SDK 4.0：
您应该添加一个按钮，并在按钮操作中使用以下代码：
- (IBAction)loginButtonClicked:(id)sender {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
// Process error
NSLog(@"error %@",error);
} else if (result.isCancelled) {
// Handle cancellations
NSLog(@"Cancelled");
} else {
if ([result.grantedPermissions containsObject:@"email"]) {
// Do work
NSLog(@"%@",result);
NSLog(@"Correct");
}
}
}];
}
更新 ：接收用户信息
- (IBAction)loginButtonClicked:(id)sender {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
// Process error
NSLog(@"error %@",error);
} else if (result.isCancelled) {
// Handle cancellations
NSLog(@"Cancelled");
} else {
if ([result.grantedPermissions containsObject:@"email"]) {
// Do work
[self fetchUserInfo];
}
}
}];
}
-(void)fetchUserInfo {
if ([FBSDKAccessToken currentAccessToken]) {
NSLog(@"Token is available");
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(@"Fetched User Information:%@", result);
}
else {
NSLog(@"Error %@",error);
}
}];
} else {
NSLog(@"User is not Logged in");
}
}
