AppB中获取AppA的照片

URLType配置

分别配置 两个应用的 URLType

AppA定义URLType为AppA0000000000

AppB定义URLType为AppB0000000000

AppB在需要获取AppA中的图片使用如下方法

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"AppA0000000000://demo.prefix?imageName=aaa"]];

AppA中

拦截方法获取处理图片并返回给AppB

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url 
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{
    if ([[url host] isEqualToString:@"demo.prefix"]) {
        NSArray *params = [[url query] componentsSeparatedByString:@"&"];
        for (NSString *param in params) {
            NSArray *keyValue = [param componentsSeparatedByString:@"="];
            NSString *value = [keyValue lastObject];
            UIImage *image = [UIImage imageNamed:value];
            NSData *data = UIImagePNGRepresentation(image);
            NSString *base64String = [data base64EncodedStringWithOptions:0];
            NSURL url = [NSURL URLWithString:[NSString 
stringWithFormat:@"AppB0000000000://%@", base64String]];
            // 将base64后的字串带给AppB
 				[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
        }
    }
    return YES;
}

AppB中同上述AppA的方法进行拦截获取图片
