我正在xCode5上将旧的iOS 5项目转换为iOS6.0,并且大多数警告和错误已经修复但是对于这个.有关如何重写代码以避免编译器警告的任何建议.

#define kBitsPerComponent 8
#define kBitmapInfo       kCGImageAlphaPremultipliedLast

 - (UIImage*)scaleToSize:(CGSize)size :(UIImage *)image
{
CGBitmapInfo bitmapInfo = kBitmapInfo;
size_t bytesPerRow = size.width * 4.0;
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
CGContextRef context = CGBitmapContextCreate(NULL, size.width,
                                             size.height, kBitsPerComponent,
                                             bytesPerRow, colorSpace, bitmapInfo);

CGRect rect = CGRectMake(0.0f, 0.0f, size.width, size.height);
CGContextDrawImage(context, rect, image.CGImage);

CGImageRef scaledImageRef = CGBitmapContextCreateImage(context);
UIImage* scaledImage = [UIImage imageWithCGImage:scaledImageRef];

CGImageRelease(scaledImageRef);
CGContextRelease(context);
CGColorSpaceRelease(colorSpace);

return scaledImage;
}

代码提供警告隐式转换从枚举类型'枚举CGImageAlphaInfo'到不同的枚举类型'CGBitmapinfo'(又名)'枚举CGBitmapInfo')

如果有人可以帮助修改代码,我将非常感激.

在Xcode 5上将项目从iOS5.0转换为iOS7/iOS6.下面的代码给出了编译时警告:

'sizeWithFont:constrainedToSize:lineBreakMode:'不推荐使用:首先在ios 7.0中弃用 - 使用 - boundingRectWithSize:options:attribiutes:context

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.section == 0)
    {
        self.lblHidden.frame = CGRectMake(58, 228, 945, 9999);
        self.lblHidden.text = detailShareObj.pDesc;
        CGSize size = [detailShareObj.pDesc sizeWithFont:self.lblHidden.font constrainedToSize:self.lblHidden.frame.size lineBreakMode:NSLineBreakByWordWrapping];
        return 228.0+size.height+20;

    }
    else if (indexPath.section == 1)
    {
        NSString *tempPointStr = (self.shortDescArray)[indexPath.row];

        self.lblHidden.frame = CGRectMake(58, 0, 945, 9999);
        self.lblHidden.text = tempPointStr;
        CGSize size = [tempPointStr sizeWithFont:self.lblHidden.font
                               constrainedToSize:self.lblHidden.frame.size
                                   lineBreakMode:NSLineBreakByWordWrapping];

            return 50.0f;
    }

我尝试了其他地方给出的一些建议,但是如果有人可以通过提供代码中所需的更正来提供帮助,那么没有什么可以解决的.
