objective-c - 您可以将 FBSnapshottestcase 库与 Swift 一起使用吗？

Question

我有 fbsnapshottestcase库和子类 FBSnapshotTestCase 在我的 iOS 项目中的测试文件中。但是，如果我尝试调用 FBSnapshotVerifyView，我会收到一个方法未找到错误。

Answer 1

您可以制作扩展并将其导入到桥接文件中:

FBSnapshotTestCase+SwiftAdditions.h:

#import <Foundation/Foundation.h>
#import <FBSnapshotTestCase/FBSnapshotTestCase.h>

@interface FBSnapshotTestCase (SwiftAdditions)

- (void) snapshotVerifyView:(UIView *)view withIdentifier:(NSString *)identifier;
- (void) snapshotVerifyLayer:(CALayer *)layer withIdentifier:(NSString *)identifier;

@end

FBSnapshotTestCase+SwiftAdditions.m:

#import "FBSnapshotTestCase+SwiftAdditions.h"

@implementation FBSnapshotTestCase (SwiftAdditions)

- (void) snapshotVerifyView:(UIView *)view withIdentifier:(NSString *)identifier
{
    FBSnapshotVerifyView(view, identifier);
}

- (void) snapshotVerifyLayer:(CALayer *)layer withIdentifier:(NSString *)identifier
{
    FBSnapshotVerifyLayer(layer, identifier);
}

@end
