RestKit：多个RKClients /更改baseURL

我在applicationDidFinishLaunching的应用程序委托中初始化RKClient的sharedClient，它工作的很好。我在大多数应用程序中使用这个客户端的目标URL，但是在1个类（播放器）中，我需要从gravatar.com加载用户的头像。所以，我有Player类定义它自己的RKClient并符合RKRequestDelegate协议。然后它通过这个新的RKClient实例发出请求，并将请求的委托设置为self。问题是我从来没有收到回应;即RestKit：多个RKClients /更改baseURL

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

永远不会被调用。这里是整个代码示例：

// 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，我还试图改变sharedClient的基本URL，只是使用了的gravatar请求sharedClient。但每当我试图改变RKClient sharedClient的基本URL特性，通过以下两种方式：

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

或

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

我得到一个运行时错误：

的clientWithBaseURL:方法预计NSString，而不是NSURL。尝试使用

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

你只需要到Targets->构建设置 - >其他链接器标记

正如RestKit教程中指定我们改变添加了一个名为“-ObjC-all_load”标志现在编辑那只显示“-ObjC”

这必须为你起锅。

我用：

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

为我工作。
