RestKit：多個RKClients /更改baseURL

我在applicationDidFinishLaunching的應用程序委託中初始化RKClient的sharedClient，它工作的很好。我在大多數應用程序中使用這個客戶端的目標URL，但是在1個類（播放器）中，我需要從gravatar.com加載用戶的頭像。所以，我有Player類定義它自己的RKClient並符合RKRequestDelegate協議。然後它通過這個新的RKClient實例發出請求，並將請求的委託設置爲self。問題是我從來沒有收到迴應;即RestKit：多個RKClients /更改baseURL

- (void)request:(RKRequest *)request didLoadResponse:(RKResponse *)response

永遠不會被調用。這裏是整個代碼示例：

// Player.m 

#import "Player.h" 

@implementation Player 

# pragma mark - Accessor Synthesizers 

@synthesize identifier = _identifier; 
@synthesize name = _name; 
@synthesize story = _story; 
@synthesize emailHash = _emailHash; 
@synthesize pointPercentage = _pointPercentage; 
@synthesize hitPercentage = _hitPercentage; 
@synthesize lastCups = _lastCups; 
@synthesize shotCount = _shotCount; 
@synthesize hitCount = _hitCount; 
@synthesize wins = _wins; 
@synthesize losses = _losses; 
@synthesize gravatar = _gravatar; 

# pragma mark - Instance Methods 

- (void)getGravatar { 
    RKClient *gClient = [RKClient clientWithBaseURL:[NSURL URLWithString:@"http://gravatar.com"]]; 
    NSString *path = [self gravatarLink]; 
    NSLog(@"Getting Gravatar With Link: http://gravatar.com%@", path); 
    [gClient get:path delegate:self]; 
} 

- (NSString *)description { 
    return [NSString stringWithFormat:@"{Season: [id=%i, name=%@, story=%@ ]}", _identifier, _name, _story]; 
} 

# pragma mark - RKRequest Delegate Methods 

- (void)request:(RKRequest *)request didLoadResponse:(RKResponse *)response { 
    NSLog(@"Gravatar Back: %@", response.bodyAsString); 
    self.gravatar = response.body; 
    [[NSNotificationCenter defaultCenter] postNotificationName:@"GravatarLoaded" object:self]; 
} 

# pragma mark - Private Methods 

- (NSString *)gravatarLink { 
    NSString *path; 
    path = [NSString stringWithFormat:@"/avatar/%@?d=monsterid&r=x", _emailHash]; 
    if([[UIScreen mainScreen] respondsToSelector:@selector(scale)] && [[UIScreen mainScreen] scale]==2) 
     return [path stringByAppendingString:@"&s=200"]; 
    else 
     return [path stringByAppendingString:@"&s=100"]; 
} 

@end

另外，我還試圖改變sharedClient的基本URL，只是使用了的gravatar請求sharedClient。但每當我試圖改變RKClient sharedClient的基本URL特性，通過以下兩種方式：

[[RKClient sharedClient] setBaseURL:[NSURL URLWithString:@"http://gravatar.com"]];

或

[RKClient sharedClient].baseURL: [NSURL URLWithString:@"http://gravatar.com"];

我得到一個運行時錯誤：

的clientWithBaseURL:方法預計NSString，而不是NSURL。嘗試使用

[[RKClient sharedClient] setBaseURL:@"http://gravatar.com"];

你只需要到Targets->構建設置 - >其他鏈接器標記

正如RestKit教程中指定我們改變添加了一個名爲「-ObjC-all_load」標誌現在編輯那隻顯示「-ObjC」

這必須爲你起鍋。

我用：

[[RKClient sharedClient] setBaseURL:[RKURL URLWithString:@"http://gravatar.com"]];

爲我工作。
