iOS App 上架需知

Required iPhone & iPod touch Screenshot Upgrade for Retina Display
When you create or update your apps in iTunes Connect, you must upload screenshots that are high-resolution. We require your screenshots as high-resolution images so that your app is optimized for the Retina display.
The requirements for high-resolution images are 960 x 640, 960 x 600, 640 x 960, or 640 x 920 pixels. Images must be at least 72 dpi, in the RGB color space, and the file must be .jpeg, .jpg, .tif, .tiff, or .png. You can update your screenshot files at any time in iTunes Connect.

New Notification for Binaries Exceeding Cellular Network Download Size Limit
Admin and Technical users will now be notified if your resulting binary size for the App Store exceeds the cellular network download size limit of 20MB. Exceeding the limit requires your app to be downloaded over Wi-Fi. This information can help you determine if you want to resubmit your binary in order to reduce the size of your app.

Exchange Webservice (EWS)：The request failed with HTTP status 405: Method Not Allowed

通常來說出錯的是這一行(The request failed with HTTP status 405: Method Not Allowed )

FindItemResponseType findItemResponse = esb.FindItem(findItemRequest);


修正的地方為
ExchangeServiceBinding esb = new ExchangeServiceBinding();
esb.Credentials = new NetworkCredential(@"id", "pw", "domain");
esb.Url = @"https://test.com.tw/EWS/Services.wsdl";

改成
esb.Url = @"https://test.com.tw/EWS/Exchange.asmx";

[super dealloc]; 使用注意事項

在 ObjC 的類別中，物件消滅時會呼叫

- (void)dealloc {

[super dealloc];

}

通常我們會將需要釋放的資源也寫在裡面，進行資源的釋放，
特別要注意的是 [super dealloc]; 要最後才呼叫。


錯誤（會造成釋放失敗系統當掉）

- (void)dealloc {

[super dealloc];

[myobj release];
[myobj2 release];

}

正確寫法應該為

- (void)dealloc {

[myobj release];
[myobj2 release];

[super dealloc];
}
