iOS Pin It SDK,没有文档和示例代码

我正在尝试通过 Pinterest’s website.的基础教程

下载文档和iOS sdk的链接不提供文档或示例代码.其中只有捆绑包

这是我的viewcontroller.m文件

#import "ViewController.h"
#import <Pinterest/Pinterest.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    UIButton* pinItButton = [Pinterest pinItButton];
    [pinItButton addTarget:self
                    action:@selector(pinIt:)
          forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:pinItButton];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)pinIt:(id)sender
{
    Pinterest *pinterest = [[Pinterest alloc]initWithClientId:@"1431885" urlSchemeSuffix:@"pin1431885"];
    [pinterest createPinWithImageURL:@"http://www.warrenphotographic.co.uk/photography/bigs/10122-Silver-and-red-kittens-white-background.jpg" sourceURL:@"http://placekitten.com" description:@"Pinning from Pin It Demo"];
}

@end

我的代码相当直接,我无法让它在我的开发iPhone上运行
它一直在扔：

您将URL作为NSString对象发送. NSString没有-absoluteString方法,这就是崩溃日志告诉你的.

Pinterest方法的声明(在Pinterest.h中)如下：

- (void)createPinWithImageURL:(NSURL *)imageURL
                    sourceURL:(NSURL *)sourceURL
                  description:(NSString *)descriptionText;

您需要为imageURL和sourceURL发送NSURL对象,而不是NSString.

所以对于你的情况：

- (void)pinIt:(id)sender
{
    NSURL *imageURL     = [NSURL URLWithString:@"http://www.warrenphotographic.co.uk/photography/bigs/10122-Silver-and-red-kittens-white-background.jpg"];
    NSURL *sourceURL    = [NSURL URLWithString:@"http://placekitten.com"];

    Pinterest *pinterest = [[Pinterest alloc]initWithClientId:@"1431885" urlSchemeSuffix:@"pin1431885"];
    [pinterest createPinWithImageURL:imageURL
                           sourceURL:sourceURL
                         description:@"Pinning from Pin It Demo"];
}
