我的应用扩展程序需要从许多网站打开URL.我做如下:

for (NSExtensionItem *item in self.extensionContext.inputItems) {

    for (NSItemProvider *itemProvider in item.attachments) {

        if ([itemProvider hasItemConformingToTypeIdentifier:(NSString *)kUTTypeURL]) {

            [itemProvider loadItemForTypeIdentifier:(NSString *)kUTTypeURL options:nil completionHandler:^(NSURL *url, NSError *error) {
                NSLog(@"URL: %@",url);

我可以获取URL,但此时我收到此错误:

App Transport Security已阻止明文HTTP(http://)资源加载,因为它不安全.可以通过应用程序的Info.plist文件配置临时例外.

我试图完全关闭ATS,

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key> <true/>
    </dict>

但它不起作用,我无法在NSExceptionDomain中列出网站.我试过模拟器和设备.有人可以帮忙吗？

我认为导致问题的代码是这样的:

NSString* htmlString = [NSString stringWithContentsOfURL: url encoding:NSUTF8StringEncoding]

我在url log之后使用这行代码将html作为纯文本.

在我的iOS应用程序中创建一个pdf programmaicallly我在mobile.tut +上关注本教程:

http://mobile.tutsplus.com/tutorials/iphone/generating-pdf-documents/

但是iOS7中现在已经弃用了两种方法,但是xcode建议使用而不是旧方法似乎不起作用.有人有想法吗？

谢谢!

    - (CGRect)addText:(NSString*)text withFrame:(CGRect)frame fontSize:(float)fontSize{
    UIFont *font = [UIFont fontWithName:@"HelveticaNeue-Light" size:fontSize];

    NSMutableParagraphStyle *paragraph = [[NSMutableParagraphStyle alloc] init];
    paragraph.alignment = NSTextAlignmentNatural;

    NSDictionary*attributi = @{ NSForegroundColorAttributeName: [UIColor blackColor],NSFontAttributeName: font, NSParagraphStyleAttributeName: paragraph};

    NSStringDrawingContext* drawCont = [[NSStringDrawingContext alloc]init];
    drawCont.minimumScaleFactor = 0.0;


    //IOS6 deprecated method

//  CGSize stringSize = [text sizeWithFont:font constrainedToSize:CGSizeMake(_pageSize.width - 2*20-2*20, _pageSize.height - 2*20 - 2*20) lineBreakMode:NSLineBreakByWordWrapping];

//IOS7 method suggested by xcode

    CGRect stringSIZ = [text boundingRectWithSize:CGSizeMake(_pageSize.width - 2*20-2*20, _pageSize.height - 2*20 - 2*20) options:NSStringDrawingUsesLineFragmentOrigin attributes:attributi context:drawCont]; …

我需要在我的应用程序的第一次运行时从主包中复制一些png到文档文件夹.我需要它,因为我必须将这些图像的文件路径保存在核心数据实体中.

我试过这种方式,但它不起作用,有谁知道为什么？

// to copy image from main bundle to documents folder

NSString* mainBundleFilePath = [[NSBundle mainBundle] pathForResource:@"SbriciolataDiRicotta" ofType:@"png"];

NSArray *destPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [destPath objectAtIndex:0];

 NSData *mainBundleFile = [NSData dataWithContentsOfFile:mainBundleFilePath];
[[NSFileManager defaultManager] createFileAtPath:documentsDirectory
                                        contents:mainBundleFile
                                      attributes:nil];

// to save the file path

NSString*nomeImmagine = [[NSString alloc] initWithFormat:@"SbriciolataDiRicotta"];
NSString *pngFilePath = [NSString stringWithFormat:@"%@/%@.png",documentsDirectory, nomeImmagine];

谢谢
