我已經看到了這個崩潰也和無法在本地重現，但它似乎這個問題是FBSDKGraphRequestConnection.m上NSString使用containsString:，這是隻有在iOS可用8.0+。

// in NSString.h (iOS 8.4) 
- (BOOL)containsString:(NSString *)aString NS_AVAILABLE(10_10, 8_0); 

在FB SDK 4.5對應的線路

// in FBSDKGraphRequestConnection.m (line 349) 
![request.graphPath containsString:@"fields="]) { 

然而，這個問題似乎是固定在4.5.1（見this diff）。

被考慮的行現在是

// in FBSDKGraphRequestConnection.m (line 349) 
[request.graphPath rangeOfString:@"fields="].location == NSNotFound) { 

所以更新到4.5.1，你應該罰款。
