iphone - iOS :App crash on [[FBSDKLoginManager new] logOut]; -

-

when logged in fblogin loggedin & on click of logout logout if removed background or rerun project has bloggedin & try logg out app crashes ….same function working without removing background & not working on relaunch function:

[[fbsdkloginmanager new] logout];

@abstract logs user out @discussion calls [fbsdkaccesstoken setcurrentaccesstoken:nil] , [fbsdkprofile setcurrentprofile:nil].

- (void)logout

also tried logout these 2 method [fbsdkaccesstoken setcurrentaccesstoken:nil] , [fbsdkprofile setcurrentprofile:nil].

there difference between 'new' , 'alloc init'. try following:

fbsdkloginmanager *fbmanager = [[fbsdkloginmanager alloc] init]; [fbmanager logout];

this function st3 = (x, y) -> console.log "#{x?}, #{y?}" if [x?, y?] [true, true] # <- line 'good' 'bad' this output true, true bad i want able tuple comparison in python. in python, if can written as if (x, y) == (true, false): return 'good' the coffescript if loop translated javascript such if ([x != null, y != null] === [true, true]) { 'good'; } that's why not evaluated true. is there alternative way express in coffeescript? if want check see if of arguments not none , this: def check_all(*args): return all(arg not none arg in args) if wanted check if they're true (like literally true) use def check_all(*args): return all(arg true arg in args) if wanted take in list (instead of variable number of parameters, remove asterisk.
