iOS NSMutableDictionary中UIImage的存储和读取

思路:将UIImage转换成NSData,然后插入到NSMutableDictionary中。读取时,用NSData读出来,然后再转换成UIImage

-存储

UIImage *image = [self getPicture: id];
NSData *imageData = http://www.mamicode.com/UIImagePNGRepresentation(image);"imageData"];

-读取

NSData *imageData = http://www.mamicode.com/[object objectForKey:@"imageData"];
if (imageData) {
    UIImage *image = [[UIImage alloc] initWithData:imageData];
    imageView.image = image;
}
else{
    //...
}
