Represents an immutable Facebook profile

Discussion:

This class provides a global "currentProfile" instance to more easily add social context to your application. When the profile changes, a notification is posted so that you can update relevant parts of your UI and is persisted to NSUserDefaults. Typically, you will want to call enableUpdatesOnAccessTokenChange:YES so that it automatically observes changes to the [FBSDKAccessToken currentAccessToken]. You can use this class to build your own FBSDKProfilePictureView or in place of typical requests to "/me".

資產

firstName

The user's first name

@property (nonatomic,
    readonly) NSString *firstName;

宣告於： FBSDKProfile.h

lastName

The user's last name

@property (nonatomic,
    readonly) NSString *lastName;

宣告於： FBSDKProfile.h

linkURL

A URL to the user's profile.

@property (nonatomic,
    readonly) NSURL *linkURL;

Discussion:

Consider using Bolts and FBSDKAppLinkResolver to resolve this to an app link to link directly to the user's profile in the Facebook app.

middleName

The user's middle name

name

The user's complete name

@property (nonatomic,
    readonly) NSString *name;

refreshDate

The last time the profile data was fetched.

@property (nonatomic,
    readonly) NSDate *refreshDate;

類別方式

currentProfile

Gets the current FBSDKProfile instance.

+ (FBSDKProfile *) currentProfile;

宣告於： FBSDKProfile.h

enableUpdatesOnAccessTokenChange:

Indicates if currentProfile will automatically observe FBSDKAccessTokenDidChangeNotification notifications

參數	說明
`enable`	YES is observing

+ (void) enableUpdatesOnAccessTokenChange:(BOOL)enable;

Discussion:

If observing, this class will issue a graph request for public profile data when the current token's userID differs from the current profile. You can observe FBSDKProfileDidChangeNotification for when the profile is updated. Note that if [FBSDKAccessToken currentAccessToken] is unset, the currentProfile instance remains. It's also possible for currentProfile to return nil until the data is fetched.

loadCurrentProfileWithCompletion:

Loads the current profile and passes it to the completion block.

參數	說明
`completion`	The block to be executed once the profile is loaded

+ (void)

	`loadCurrentProfileWithCompletion`
	`void`
	`^`
	`FBSDKProfile`
	`profile`
	`NSError`
	`error`
	`completion;`

Discussion:

If the profile is already loaded, this method will call the completion block synchronously, otherwise it will begin a graph request to update currentProfile and then call the completion block when finished.

宣告於： FBSDKProfile.h

setCurrentProfile:

Sets the current instance and posts the appropriate notification if the profile parameter is different than the receiver.

參數	說明
`profile`	The profile to set

+ (void) setCurrentProfile:(FBSDKProfile *)profile;

Discussion:

This persists the profile to NSUserDefaults.

執行個體方法

imagePathForPictureMode:size:

A convenience method for returning a Graph API path for retrieving the user's profile image.

參數	說明
`mode`	The picture mode
`size`	The height and width. This will be rounded to integer precision.

- (NSString *)

`imagePathForPictureMode:`	`(FBSDKProfilePictureMode)mode`
`size:`	`(CGSize)size`

__attribute__((deprecated("use imageURLForPictureMode:size: instead")));

Discussion:

You can pass this to a FBSDKGraphRequest instance to download the image.

宣告於： FBSDKProfile.h

imageURLForPictureMode:size:

A convenience method for returning a complete NSURL for retrieving the user's profile image.

參數	說明
`mode`	The picture mode
`size`	The height and width. This will be rounded to integer precision.

- (NSURL *)

`imageURLForPictureMode:`	`(FBSDKProfilePictureMode)mode`
`size:`	`(CGSize)size;`

宣告於： FBSDKProfile.h

initWithUserID:firstName:middleName:lastName:name:linkURL:refreshDate:

Initializes a new instance.

參數	說明
`userID`	The user ID
`firstName`	The user's first name
`middleName`	The user's middle name
`lastName`	The user's last name
`name`	The user's complete name
`linkURL`	The link for this profile
`refreshDate`	The optional date this profile was fetched. Defaults to [NSDate date].

- (instancetype)

`initWithUserID:`	`(NSString *)userID`
`firstName:`	`(NSString *)firstName`
`middleName:`	`(NSString *)middleName`

isEqualToProfile:

Returns YES if the profile is equivalent to the receiver.

參數	說明
`profile`	The profile to compare to.

- (BOOL) isEqualToProfile:(FBSDKProfile *)profile;

宣告於： FBSDKProfile.h

常數

FBSDKProfileDidChangeNotification

FBSDK_EXTER N NSString *const FBSDKProfileDidChangeNotification;

Discussion:

The userInfo dictionary of the notification will contain keys FBSDKProfileChangeOldKey and FBSDKProfileChangeNewKey.
