Instagram 分享
大概流程如下：
分享：无需获取权限，通过Custom URL Scheme或者Document Interaction 分享出去后停留在Instagram，无回调（返回值）。
另外：通过授权（账号和密码）的方式，可以获取用户的公开内容。
登陆权限有如下几种：
获取较高权限，比如：public_content可以拿到用户发布的图片和视频内容。 备注：
客服端申请权限，目前只申请下来basic权限，public_content权限没申请下来，没能继续测试是否能拿到用户发布的内容，但是理论上是可以的，且看下面的介绍）
根据官方文档的介绍：
第一步：授权，获取access_token;
第二步：get用户最新发布的media。
请求的url及参数如上图所示，返回的结果如下图所示。
结论：可以先请求用户授权，然后分享照片，最后获取最新发布的信息。

通过 URL Scheme 分享，截图如下：
-(void)loadInstagram{
NSURL *url = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
[[UIApplication sharedApplication] openURL:url];
}else{
NSLog(@"did not install instagram");
[self showAlterWithStr:@"did not install instagram"];
}
}
通过UIDocumentInteractionController,原文档说明如下：
示例代码：
-(void)shareToInstagramByDocumentImage:(NSString *)imageStr{
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]){
dispatch_async(dispatch_get_global_queue(0, 0), ^{
UIImage *image = [UIImage imageNamed:imageStr];
NSString *name = [NSString stringWithFormat:@"%f%u.igo",[NSDate timeIntervalSinceReferenceDate],arc4random_uniform(1000)];
NSString *savePath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES).firstObject stringByAppendingPathComponent:name];
[UIImagePNGRepresentation(image) writeToFile:savePath atomically:YES];
dispatch_async(dispatch_get_main_queue(), ^{
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
self.documentInteractionController.UTI = @"com.instagram.exclusivegram";
self.documentInteractionController.delegate = self;
[self.documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
});
});
}else{
NSLog(@"did not install instagram");
[self showAlterWithStr:@"did not install instagram"];
}
}
-(void)shareToInstagramByImage:(NSString *)imageStr{
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]){
dispatch_async(dispatch_get_global_queue(0, 0), ^{
UIImage *image = [UIImage imageNamed:imageStr];
NSString *name = [NSString stringWithFormat:@"%f%u.ig",[NSDate timeIntervalSinceReferenceDate],arc4random_uniform(1000)];
NSString *savePath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES).firstObject stringByAppendingPathComponent:name];
[UIImagePNGRepresentation(image) writeToFile:savePath atomically:YES];
dispatch_async(dispatch_get_main_queue(), ^{
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
self.documentInteractionController.UTI = @"com.instagram.photo";
self.documentInteractionController.delegate = self;
[self.documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
});
});
}else{
NSLog(@"did not install instagram");
[self showAlterWithStr:@"did not install instagram"];
}
}
-(void)shareToInstagramByDocumentnNameWith:(NSString *)imageName{
NSURL *instagramUrl = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramUrl]){
NSString *jpgPath = [[NSBundle mainBundle] pathForResource:imageName ofType:nil];
NSURL *imageUrl = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:imageUrl];
self.documentInteractionController.UTI = @"com.instagram.photo";
self.documentInteractionController.delegate = self;
[self.documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
}else{
NSLog(@"did not install instagram");
[self showAlterWithStr:@"did not install instagram"];
}
}
