你好,我需要将编辑过的图片导入到Instagram中,就像PhotoStudio一样:
我使用以下代码来捕获我的图像:
UIGraphicsBeginImageContextWithOptions(self.captureView.bounds.size, self.captureView.opaque, 0.0);
[self.captureView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
我需要使用Instagram打开这个screenShot
:
编辑后:
我像这样实现了这个方法:
UIGraphicsBeginImageContextWithOptions(self.captureView.bounds.size, self.captureView.opaque, 0.0);
[self.captureView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", screenshot]];
docFile.UTI = @"com.instagram.photo";
[self setupDocumentControllerWithURL:igImageHookFile];
NSURL *instagramURL = [NSURL URLWithString:@"instagram://media?id=MEDIA_ID"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
[[UIApplication sharedApplication] openURL:instagramURL];
}
else {
NSLog(@"No Instagram Found");
}
}
但是我收到了这个输出:
2012-05-05 21:55:36.842 InstantFrame[855:707] *** Assertion failure in -[UIDocumentInteractionController setURL:], /SourceCache/UIKit/UIKit-1914.84/UIDocumentInteractionController.m:1094

Instagram将被打开,但不会导入任何内容。
