如何在Pinterest上发布图片？

我想用this链接张贴在Pinterest的形象，但我改变编码点点根据我自己的要求，这里是我MainClass代码如何在Pinterest上发布图片？

- (void)pInterest { 
     UIImage *myImage; 
     myImage=imgView.image; 
     WebViewController *webViewController = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:nil]; 
     webViewController.mypimage = myImage; 
    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentModalViewController:webViewController animated:YES]; 
}

所以通过图像我WebViewController后，现在我的WebViewController类代码为

- (void)viewDidLoad { 
    //imageview.image=mypimage; 
    [super viewDidLoad]; 
    NSString *description = @"Post your description here"; 

    // Generate urls for button and image 
    NSString *sUrl = [NSString stringWithFormat:@"http://d30t6wl9ttrlhf.cloudfront.net/media/catalog/product/Heros/mypimage"]; 
    // NSLog(@"URL:%@", sUrl); 
    NSString *protectedUrl = (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(__bridge CFStringRef)sUrl, NULL, (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)); 
    NSLog(@"Protected URL:%@", protectedUrl); 
    NSString *imageUrl = [NSString stringWithFormat:@"\"%@\"", sUrl]; 
    NSString *buttonUrl = [NSString stringWithFormat:@"\"http://pinterest.com/pin/create/button/?url=www.flor.com&media=%@&description=%@\"", protectedUrl, description]; 

    NSMutableString *htmlString = [[NSMutableString alloc] initWithCapacity:1000]; 
    [htmlString appendFormat:@"<html> <body>"]; 
    [htmlString appendFormat:@"<p align=\"center\"><a href=%@ class=\"pin-it-button\" count-layout=\"horizontal\"><img border=\"0\" src=\"http://assets.pinterest.com/images/PinExt.png\" title=\"Pin It\" /></a></p>", buttonUrl]; 
    [htmlString appendFormat:@"<p align=\"center\"><img width=\"400px\" height = \"400px\" src=%@></img></p>", imageUrl]; 
    [htmlString appendFormat:@"<script type=\"text/javascript\" src=\"//assets.pinterest.com/js/pinit.js\"></script>"]; 
    [htmlString appendFormat:@"</body> </html>"]; 
    [mywebview setBackgroundColor:[UIColor clearColor]]; 
    [mywebview loadHTMLString:htmlString baseURL:nil]; 
    [mywebview setOpaque:NO]; 
}

当我使用上面的编码我的WebView不显示图像和我的WebView看起来像下面screenshow enter image description here

当我将相同的图像实例分配给WebViewController中的图像视图时，其工作imageview.image = mypimage;

所以有人可以告诉我为什么我的webveiw不显示图像。谢谢。

我应该说这不是一个合适的按钮url。请务必在实际发布问题之前确保您尝试加载的资源的网址存在。 – 2013-02-01 22:22:26

当我点击pinit按钮，它是在第一张截图上打开第二张截图，这意味着没有关于url.so的问题，唯一的问题是它不能传递我的图像。 – jamil

使用此代码......希望它能帮助你。

- (IBAction)pinit:(id)sender { 
    [self postToPinterest]; 
} 

- (IBAction)closeWebVIew:(id)sender { 
    [webViewPinterest setHidden:YES]; 
} 

- (NSString*) generatePinterestHTML { 
    NSString *description = @"Post your description here"; 
NSURL* sUrl = [NSString stringWithFormat:@"http://4.bp.blogspot.com/-w4oTZjlpgwo/T5_pi-KJPuI/AAAAAAAAAoM/rKm3E0XCbgY/s1600/red_rose_flower3.jpg"];// pass your link here with your image name 

    NSLog(@"URL:%@", sUrl); 
    NSString *protectedUrl = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)sUrl, NULL, (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)); 
    NSLog(@"Protected URL:%@", protectedUrl); 
    NSString *imageUrl = [NSString stringWithFormat:@"\"%@\"", sUrl]; 
    NSString *buttonUrl = [NSString stringWithFormat:@"\"http://pinterest.com/pin/create/button/?url=www.flor.com&media=%@&description=%@\"", protectedUrl, description]; 

    NSMutableString *htmlString = [[NSMutableString alloc] initWithCapacity:1000]; 
    [htmlString appendFormat:@"<html> <body>"]; 
    [htmlString appendFormat:@"<p align=\"center\"><a href=%@ class=\"pin-it-button\" count-layout=\"horizontal\"><img border=\"0\" src=\"http://assets.pinterest.com/images/PinExt.png\" title=\"Pin It\" /></a></p>", buttonUrl]; 
    [htmlString appendFormat:@"<p align=\"center\"><img width=\"400px\" height = \"400px\" src=%@></img></p>", imageUrl]; 
    [htmlString appendFormat:@"<script type=\"text/javascript\" src=\"//assets.pinterest.com/js/pinit.js\"></script>"]; 
    [htmlString appendFormat:@"</body> </html>"]; 
    return htmlString; 
} 

- (void) postToPinterest { 
    NSString *htmlString = [self generatePinterestHTML]; 
    NSLog(@"Generated HTML String:%@", htmlString); 
    webViewPinterest.backgroundColor = [UIColor clearColor]; 
    webViewPinterest.opaque = NO; 
    if ([webViewPinterest isHidden]) { 
     [webViewPinterest setHidden:NO]; 
    } 
    [webViewPinterest loadHTMLString:htmlString baseURL:nil]; 
    //[webViewPinterest loadHTMLString:@"<img src=images.png>" baseURL:nil]; 
} 

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType { 
    return YES; 
} 

- (void)webViewDidStartLoad:(UIWebView *)webView { 
    [busyIndicator startAnimating]; 
} 

-(void)webViewDidFinishLoad:(UIWebView *)webView { 
    [busyIndicator stopAnimating]; 
}

将你的最后一篇文章标记为重复，并被版主删除，所以我在这里赔偿+ 1。请不要张贴链接作为答案。 –

@MicRO好的，谢谢...... :) –

@MicRO谢谢... :) –

之前发布一个答案，我想，要特别感谢@Sudha谁给我的想法，如果没有在服务器上发布图片，我们不能从应用程序直接Pinterest上发布局部图像。因此，当我在服务器上发布图像并将适当的URL地址分配给pinit按钮时，以这种方式移动想法，然后它对我有用。干杯! 当我开始用pinterest搜索iOS应用程序集成时，我发现这方面的帮助和材料很少。我认为大多数开发人员使用this方法，但是当我使用上面引用的方法时，它并没有在pinterest上发布我的本地应用程序图像。最后，我想为那些最有可能从应用程序发布本地图像的人发布我的答案。

步骤

创建新的类WebViewController并添加下面的东西。

#import <UIKit/UIKit.h> 

@interface WebViewController : UIViewController 
{ 
IBOutlet UIActivityIndicatorView *UIHelper; 
IBOutlet UIWebView *mywebview; 
UIImage *mypimage; 
} 
@property(nonatomic,retain)UIActivityIndicatorView *UIHelper; 
@property(nonatomic,retain)UIWebView *mywebview; 
@property(nonatomic,retain) UIImage *mypimage; 
-(IBAction)closeClicked:(id)sender ; 
@end

现在WebViewController.m文件代码

#import "WebViewController.h" 

@interface WebViewController() 

@end 

@implementation WebViewController 
@synthesize UIHelper,mypimage,mywebview; 
NSString *username; 

-(IBAction)closeClicked:(id)sender { 
[self dismissModalViewControllerAnimated:YES]; 
} 
- (void)webViewDidStartLoad:(UIWebView *)webView { 
    [UIHelper startAnimating]; 
    } 
-(void)webViewDidFinishLoad:(UIWebView *)webView { 
[UIHelper stopAnimating]; 
    } 
- (void)viewDidLoad 
{ 
    username = @"j&D"; 
[username retain]; 

NSData *imageData = UIImageJPEGRepresentation(mypimage, 90); 
NSString *urlString = @"ServerURl/cap.php"; 
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; 
[request setURL:[NSURL URLWithString:urlString]]; 
[request setHTTPMethod:@"POST"]; 
NSString *boundary = @"---------------------------14737809831466499882746641449"; 
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
[request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 
NSMutableData *body = [NSMutableData data]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n",username] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[NSData dataWithData:imageData]]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[request setHTTPBody:body]; 
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 
    NSLog(@"serverurl :%@",returnString); 

    NSString *htmlString = [self generatePinterestHTML]; 
    NSLog(@"Generated HTML String:%@", htmlString); 
    mywebview.backgroundColor = [UIColor clearColor]; 
    mywebview.opaque = NO; 
    if ([mywebview isHidden]) { 
    [mywebview setHidden:NO]; 
    } 
    [mywebview loadHTMLString:htmlString baseURL:nil]; 
    [super viewDidLoad]; 
    } 
    - (NSString*) generatePinterestHTML { 
     NSString *description = @"Post your description here"; 
     NSString *sUrl = [NSString stringWithFormat:@"SerVerUrl/cap/j&D.jpg"]; 
     NSLog(@"URL:%@", sUrl); 
     NSString *protectedUrl = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)sUrl, NULL, (CFStringRef)@"!'\"();:@&=+$,/?%#[]% ",CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)); 
     NSLog(@"Protected URL:%@", protectedUrl); 
     NSString *imageUrl = [NSString stringWithFormat:@"\"%@\"", sUrl]; 
     NSString *buttonUrl = [NSString stringWithFormat:@"\"http://pinterest.com/pin/create/button/?url=www.flor.com&media=%@&description=%@\"", protectedUrl, description]; 

     NSMutableString *htmlString = [[NSMutableString alloc] initWithCapacity:1000]; 
     [htmlString appendFormat:@"<html> <body>"]; 
     [htmlString appendFormat:@"<p align=\"center\"><a href=%@ class=\"pin-it-button\" count-layout=\"horizontal\"><img border=\"0\" src=\"http://assets.pinterest.com/images/PinExt.png\" title=\"Pin It\" /></a></p>", buttonUrl]; 
     [htmlString appendFormat:@"<p align=\"center\"><img width=\"400px\" height = \"400px\" src=%@></img></p>", imageUrl]; 
     [htmlString appendFormat:@"<script type=\"text/javascript\" src=\"//assets.pinterest.com/js/pinit.js\"></script>"]; 
     [htmlString appendFormat:@"</body> </html>"]; 
     return htmlString; 
     } 
     @end

创建一个方法，当用户点击你的“PINIT”按钮，这表明web视图与图像，你将发布和调用UIWebView上的“Pinit”按钮。这是我的代码：

-(void)pInterest 
{ 
    UIImage *myImage; 
    myImage=imgView.image; 
    WebViewController *webViewController = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:nil]; 
    webViewController.mypimage = myImage; 
    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentModalViewController:webViewController animated:YES]; 
}

注：在上面的代码用自己的服务器URL替换SERVERURL。

末做出的描述更清晰，我已经提供了一些截图，以消除任何含糊和可能出现的误解。

谢谢@Bob Apple –

Bob Apple和Sudha有没有什么办法可以在我看来适合分享屏幕意味着在320X480上共享Pinterest分享？ –

是的，你可以分享@ NikunjR.Jadav – jamil

您可以使用the Pinterest iOS SDK

Pinterest *_pinterest = [[Pinterest alloc] initWithClientId:pinterestKey]; 
[_pinterest createPinWithImageURL:@"http://placekitten.com/500/400" 
         sourceURL:@"http://placekitten.com" 
         description:@"Pinning from Pin It Demo"];

对于这个然而，你需要在设备上的应用Pinterest的。
