Я пытаюсь сделать функцию скручивания на половину страницы. Это код, который я использую:
#import <QuartzCore/QuartzCore.h>
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.0f];
[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
[animation setType:(notCurled ? @"mapCurl" : @"mapUnCurl")];
[animation setRemovedOnCompletion:NO];
[animation setFillMode: @"extended"];
[animation setRemovedOnCompletion: NO];
notCurled = !notCurled;
Но я сталкиваюсь со следующими ошибками
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_CATransition", referenced from:
objc-class-ref in MyMapViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
"_OBJC_CLASS_$_CATransition", referenced from:
objc-class-ref in SJMapViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Как мне это решить?
