App间相互跳转及图片分享

A-app:

Info--URL Types--URL Schemes:A-app(一个标识，允许别的app调用本App)

info.plist 添加白名单：

LSApplicationQueriesSchemes（Array）

B-app（String）

//使用

- (void)jumpToBapp {

/*

关于UIPasteboard，如果直接使用pasteboard.string/ pasteboard.URL /pasteboard.image等，一次只能使用一个，且用系统的话，都可以被使用（- (void)setXXX:(id)data forPasteboardType:(NSString *)pasteboardType;）

可以避免全局被使用（需要typeName）；

传字典：需要归档

NSDictionary *dic = @{@"name":@"哈哈碉堡啦",@"image":[UIImage imageNamed:@"qq"]};

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

NSData *dictData = [NSKeyedArchiver archivedDataWithRootObject:dic];

[pasteboard setData:dictData forPasteboardType:@"AType"];

接收：

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

NSDictionary *dict = [NSKeyedUnarchiver unarchiveObjectWithData:[pasteboard dataForPasteboardType:@"AType"]];

NSString *name = [dict objectForKey:@"name"];

// 1.拿到对应应用程序的URL Scheme

NSArray *arr = [self.urlString componentsSeparatedByString:@"?"];

NSString *urlSchemeString = arr[1];

NSString *urlString = [urlSchemeString stringByAppendingString:@"://"];

// 2.获取对应应用程序的URL

NSURL *url = [NSURL URLWithString:urlString];

// 3.判断是否可以打开

if ([[UIApplication sharedApplication] canOpenURL:url]) {

[[UIApplication sharedApplication] openURL:url];
