引用—–>

#import <ContactsUI/CNContactViewController.h>
#import <ContactsUI/CNContactPickerViewController.h>

5.stringByAddingPercentEscapesUsingEncoding iOS9.0後棄用

NSString *str = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

解決方案:

    NSString *string = @"hahahaha";
    NSString *Urlstring = [string stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLUserAllowedCharacterSet]];

6.UIAlertView (iOS9.0後棄用)

 UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"確定" otherButtonTitles:nil];
    [alert show];

同時棄用的還有 UIActionSheet (iOS 8.3 後棄用)

 UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:@"收款" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"保存", nil];
    actionSheet.tag = 105;
    [actionSheet showInView:self.view];

7.interfaceOrientation (iOS8.0後棄用)

    UIInterfaceOrientation toInterfaceOrientation = self.interfaceOrientation;

    if (toInterfaceOrientation == UIInterfaceOrientationPortrait) {
        [self remasMakeForVertical];
    }else{
        [self remasMakeForLandscape];

    }

8.applicationFrame(iOS 9.0 後棄用)

screenshotImgView.frame = [UIScreen mainScreen].applicationFrame;

errors:(報紅)

真機調試問題

1.launchscreen 黑屏問題

可能原因: 真機運行內存較小,launchscreen圖片過大
解決方法: 刪除掉原先的launch screen 重新建立一個launchscreen.storyBoard (iOS 8.0以下 位launchscreen.xib) 重新建立後運行成功.
希望有哪位大神可以解釋下原因.
