我正在尝试从目标C生成一些javascript。我有一个简单的objective-c对象:只有NSString
s,NSArray
s,NSDictionary
s和{{1 s - 我想将它作为对象文字插入到javascript中。最好的方法是什么?
到目前为止,我已设法序列化对象并获取JSON字符串,但JSON并不完全等同于javascript对象文字。我可以将其作为NSNumber
调用插入,但这似乎效率低下:
JSON.parse('%@')
答案 0 :(得分:0)
这是完整的代码:
//turn an NSObject into an NSString
+ (NSString *)jsonDumps:(id)obj {
NSError *error;
NSData *utf8stringified = [NSJSONSerialization dataWithJSONObject:obj options:0 error:&error];
if (utf8stringified == nil) {
[NSException raise:@"Failed to jsonify arguments" format:@"Failed to jsonify arguments %@: %@",
obj, error];
}
NSString *stringified = [[[NSString alloc] initWithData:utf8stringified encoding:NSUTF8StringEncoding]
autorelease];
return stringified;
}
//turn a JSON string into a JS literal
+(NSString *)jsonToJSLit:(NSString *)jsonString {
NSMutableString *s = [NSMutableString stringWithString:jsonString];
[s replaceOccurrencesOfString:@"\u2028" withString:@"\\u2028" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
[s replaceOccurrencesOfString:@"\u2029" withString:@"\\u2029" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
return [NSString stringWithString:s];
}
//turn an object into a JS string literal
+(NSString *)objToJSLiteral:(id)obj {
return [self jsonToJSLit:[self jsonDumps:obj]];
}
我认为JSON和JS文字之间有更多区别,但显然它只是那两个unicode字符!
