我正在尝试调整图像大小以附加到 Twitter 表。但我收到错误为“选择器方法没有已知类” imageWithImage: (UIImage)image...."
“
- (void)twitterButtonPressed {
UIImage *iconImage=[UIImage imageNamed:@"male_small_0.png"];
// I am having problem in the following line
UIImage *iconImage2=[UIImage imageWithImage:iconImage scaledToSize:CGSizeMake(73.0, 73.0)];
}
-(UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize
{
UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
[image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
UIImage *newImage =UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
