我想截取iPhone应用视图的屏幕截图并将图像保存到指定位置。
我的代码将图像保存到照片库,但我想将其保存到其他指定位置。有可能这样做吗?请帮助我。
我的代码在这里:
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, self, nil, nil);
答案 0 :(得分:3)
您可以使用NSData存储图像数据。
保存图片:
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(myImage)];
[imageData writeToFile:imagePath atomically:YES];
要检索图像:
UIImage *myImage = [UIImage imageWithContentsOfFile:imagePath];
更新#1:示例(我现在无法测试该示例,但它应该以这种方式工作):
UIGraphicsBeginImageContext(self.view.bounds.size);
self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
// Get the location of the Documents directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) ;
NSString *imagePath = [paths objectAtIndex:0];
NSString *filename = @"test.png" ;
NSString *filepath = [NSString stringWithFormat:@"%@/%@", imagePath, filename];
UIGraphicsEndImageContext();
// Save the image
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(myImage)];
[imageData writeToFile:filepath atomically:YES];
