我在iOS 7上运行良好的应用程序无法与iOS 8 SDK一起使用.
CLLocationManager没有返回位置,我也没有在设置 - > 位置服务下看到我的应用程序.我在这个问题上进行了谷歌搜索,但没有出现任何问题.可能有什么不对?

在Cocoa Touch中是否有一个好方法rect可以保存文本视图中的所有行,以便我可以相应地调整父视图?
再举一个例子,查看日历应用程序中事件的注释字段 - 注意单元格(及其UITextView包含)如何扩展以包含注释字符串中的所有文本行.
我在iOS 3.1.3 iPhone上测试我的iPhone应用程序.我使用以下方法选择/捕获图像UIImagePickerController:
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setDelegate:self];
[self.navigationController presentModalViewController:imagePicker animated:YES];
[imagePicker release];
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
self.image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = self.image;
[self.navigationController dismissModalViewControllerAnimated:YES];
submitButton.enabled = YES;

问题:当我用iphone拍照同时保持它的风景时,图像会上传到服务器并按照你的预期进行查看.当拍摄手机拍照时,图像会被上传并在旋转90度时被观看.
我的应用程序设置为仅在纵向模式下工作(颠倒和常规).
如何在上传后使图像始终显示正确的方向?
UIImageView中显示的图像看起来是正确的(在拍照后直接显示),但在服务器上查看则另有说明.
是否可以从另一个应用程序中启动任意iPhone应用程序?例如, 在我的应用程序中,如果我希望用户按下按钮并启动到手机应用程序(关闭当前应用程序,打开手机应用程序).
这有可能吗?我知道可以使用tel URL链接拨打电话,但我想改为启动Phone应用而不拨打任何特定号码.

我是反应原生编码的新手,但在Objective-c和swift编码方面经验丰富,并希望在反应原生中使用单例模式.我试图找出其他StackOverflow答案的解决方案,但大多数都只创建单例函数,如下面的代码:
var Singleton = (function () {
var instance;
function createInstance() {
var object = new Object("I am the instance");
return object;
}
return {
getInstance: function () {
if (!instance) {
instance = createInstance();
}
return instance;
}
};
})();
function run() {
var instance1 = Singleton.getInstance();
var instance2 = Singleton.getInstance();
alert("Same instance? " + (instance1 === instance2));
}

正如我们在上面的代码中看到的,我们创建的是单例函数而不是类.如果有任何方法可以创建单例类并将该类中的多个变量作为objective-c或swift传递,请告诉我.注意:如果我的方向错误,也请通知我.
在我的应用程序中,我有一个图像阵列,可以保存在我的相机上拍摄的所有图像.我正在使用collectionView来显示这些图像.但是,当此图像阵列达到大约20张图像时,它会崩溃.我相信这是由于内存问题..如何以一种内存效率的方式将图像存储在图像阵列中?
Michael Dauterman使用缩略图提供了答案.我希望除此之外还有一个解决方案.也许将图片存储到NSData或CoreData中?
