我已成功将"RestKit"pod添加到我的项目中,并且还按照本文中描述的步骤操作:Cocoapods in swift.我将RestKit导入到我的ViewController类的源文件中:
import RestKit
但我不知道为什么我无法访问它.它不会显示RestKit中的任何类.表明:
'RestKit'不存在这样的模块.
我再次尝试创建一个新项目并添加了"RestKit".并创建了一个桥接头并将"RestKit"导入ViewController claas的源文件中.现在我运行该项目它显示错误
// in this file Pods-SOCKit-prefix.pch
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#endif
#import "Pods-environment.h" // Pods-environment.h file not found
// and also in this file Pods-TransitionKit-prefix.pch
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#endif
#import "Pods-environment.h" // Pods-environment.h file not found
如果有人知道这背后的问题是什么,请向我解释一下,并建议一种在Swift中使用RestKit的方法.
请帮忙使用SFTP连接到我的服务器，我尝试了很多。但它不能正常工作。服务器工作正常。
// 第一个方法
let config = NSURLSessionConfiguration.defaultSessionConfiguration()

var assets : ALAsset = photoArray.objectAtIndex(indexPath.row) as ALAsset
cell.cameraOutlet.image = UIImage(CGImage: assets.thumbnail()) as UIImage // Showing error - Missing argument for parameter 'inBundle' in call
之后,我尝试了这段代码:
var assets : ALAsset = (photoArray.objectAtIndex(indexPath.row) as ALAsset)
var imageRef : CGImageRef = assets.thumbnail() as CGImageRef // showing error - Unmanaged<CGImage>, is not convertible to CGImageRef
cell.cameraOutlet.image = UIImage(CGImage: assets.thumbnail()) as UIImage // Showing error - Missing argument for parameter 'inBundle' in call
我想显示图像,我该怎么做？

我尽我所能,但我被困在这里.我想从iPhone相册中导入所有照片.所以我想出了这个ALAssestsLibrary API.
photoLibrary.enumerateGroupsWithTypes(ALAssetsGroupType(ALAssetsGroupSavedPhotos), usingBlock: { group in
if group != nil
{
}
}, failureBlock: { error in println("\(error)")})
如何添加这行代码.
group enumerateAssetsUsingBlock:groupEnumerAtion
我尝试添加它但它没有显示任何enumerateAssetsUsingBlock属性.？
这是实际的代码.!在Objective-C中
dispatch_async(dispatch_get_main_queue(), ^
{
@autoreleasepool
{
ALAssetsLibraryAccessFailureBlock failureblock = ^(NSError *myerror)
{
NSLog(@"error occour =%@", [myerror localizedDescription]);
};
ALAssetsGroupEnumerationResultsBlock groupEnumerAtion = ^(ALAsset *result, NSUInteger index, BOOL *stop)
{
if (result!=NULL)
{
if ([[result valueForProperty:ALAssetPropertyType] isEqualToString:ALAssetTypePhoto])
{
[self.g_imageArray addObject:result];
}
}
};

var emailViewController : MFMailComposeViewController = MFMailComposeViewController()
emailViewController.mailComposeDelegate = self
emailViewController.setToRecipients(["----"])
emailViewController.setSubject("----")
emailViewController.setMessageBody("\n\n\n" + "-- \r\n " + "----- Device : \(self.deviceName), App Version : \(self.appVersion), Model : \(deviceModel) , iOS Version : \(self.deviceVersion), Country Code : \(self.countryCode), Localised Model : \(deviceLocalizedModel) \n \n \n", isHTML: true)
self.presentViewController(emailViewController, animated: true, completion: nil)
大家看到我在内容中加了“ \ n”，但在emailBody中未显示新行。如果有人知道如何在emailMessageBody中获得一些新行，请帮助。
