我创建了一个自定义反应本机自定义UI组件，该组件应集成第三方ios广告sdk。
这是我的代码：
#import "RDUAdCenterManager.h"
#if __has_include(<React/RCTBridge.h>)
#import <React/RCTBridge.h>
#import <React/RCTUIManager.h>
#import <React/RCTEventDispatcher.h>
#else
#import "RCTBridge.h"
#import "RCTUIManager.h"
#import "RCTEventDispatcher.h"
#endif
/* ———————————————————————————————————————————————————————————————————————— */
@interface NSError (SDK_Util)
/**
* Returns a text representation of the receiver's contents.
*/
- (NSString *)textRepresentation;
@end // NSError (SDK_Util)
@implementation RDUAdCenterManager
RCT_EXPORT_MODULE()
/* ———————————————————————————————————————————————————————————————————————— */
#pragma mark -

*/
- (void)dealloc
{
[mAdsView prepareForShutdown];
[mAdsView removeFromSuperview];
#if ! __has_feature(objc_arc)
[mAdsView release];
#endif // objc_arc
mAdsView = nil;
#if ! __has_feature(objc_arc)
[super dealloc];
#endif // objc_arc
} /* dealloc */
/* ———————————————————————————————————————————————————————————————————————— */
- (UIView *)view
{
//CGSize room = mAdsView.frame.size;
CGRect adFrame = CGRectMake(0, 0, 300, 250);
mAdsView = [[AdsView alloc] initInlineWithFrame:adFrame delegate:self];
// Add some profile targeting for good measure.
NSError *error = nil;
// Load an ad with the above targeting properties.
if (error == nil)
{
[mAdsView loadCreativeFromNetwork:@"DEMO" withContentUnitID:@"DEMO" error:&error];
}
if (error != nil)
{
NSLog(@" # %@", [error textRepresentation]);
}
return mAdsView;
}
/* ———————————————————————————————————————————————————————————————————————— */
#pragma mark -
#pragma mark —— Protocol Conformance ——
/* ———————————————————————————————————————————————————————————————————————— */
#pragma mark -
#pragma mark — AdsViewDelegate —
/* ———————————————————————————————————————————————————————————————————————— *
* Lets the app developer inform the SDK ahead of time which superview

*/
- (UIView *)futureSuperviewForAd:(AdsView *)inAdsView
{
return self.view;

- (void)adFinishedLoading:(AdsView *)inAdsView withSuccessOrError:(NSError *)inError
{
if (inAdsView == mAdsView)
{
if (inError != nil)
{
// An error occured while attempting to load the ad's WebView from local cache.
// Perform last rites...
[inAdsView prepareForShutdown];
[inAdsView removeFromSuperview];
// ... and deallocate.
#if ! __has_feature(objc_arc)
[inAdsView release];
#endif // objc_arc
mAdsView = nil;
NSLog(@" # %@", [inError textRepresentation]);
}
}
} /* adFinishedLoading:withSuccessOrError: */
/* ———————————————————————————————————————————————————————————————————————— *

*/
- (void)runningAd:(AdsView *)inAdsView encounteredError:(NSError *)inError
{
// At least the Development build of your app should log or otherwise handle any & all errors.
NSLog(@" # %@", [inError textRepresentation]);

*/
- (void)openBrowserForAd:(AdsView *)inAdsView withURL:(NSURL *)inURL
{
// Pass the URL to the standard handler app.
if (! [[UIApplication sharedApplication] openURL:inURL])
{
// OS doesn't know how to open.
NSLog(@" # Unsupported URL type: %@", inURL);
}
// We don't capture interaction with a modal view in this
// app so we return control to the AdsView immediately.
[inAdsView resumeFromAppDefinedBrowser];
} /* openBrowserForAd:withURL: */
@end
这在我们的测试中效果很好，并且可以正确显示，但是在投入生产的几天后，我们遇到了几次Crashlytics崩溃，它们读为或类似内容：

从我的研究中，我发现它可能与不再可用的指针或类似指针相关联，但是我对Objective-C经验不足，也不知道从哪里开始调试。 / p>
在此软件包的android部分中，我们遇到了ReactContext未在后台定义的问题。也许这里很相似。
