##### 1.NSArray / NSString / NSDictionary 不会自动转成对应的JS类型，像普通 NSObject 一样使用它们
Important annotations that needs attention:
//OC
implementation JPObject
+(NSArray *)data
{
return @[[NSMutableString stringWithString:@"JS"]];
}
+(NSMutableDictionary *)dict{
return [[NSMutableDictionary alloc] init];
}
@end
//js
require('JPObject')
var ocStr = JPObject.data().objectAtIndex(0)
ocStr.appendString("Patch")
var dict = JPObject.dict()
##### 2 dic如果要把 NSArray / NSString / NSDictionary 转为对应的 JS 类型，使用 .toJS() 接口:t.setObject_forKey(ocStr, 'name')
// JS
var data = require('JPObject').data().toJS()
//data instanceof Array === true
data.push("Patch")
var dict = JPObject.dict()
dict.setObject_forKey(data.join(''), 'name')
dict = dict.toJS()
console.log(dict['name']) //output: JSPatch
console.log(dict.objectForKey('name')) //output: JSPatch
#####3 使用 dispatch_after() dispatch_async_main() dispatch_sync_main() dispatch_async_global_queue() 接口调用GCD方法:
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
// do something
});
dispatch_async(dispatch_get_main_queue(), ^{
// do something
});
//js
dispatch_after(1.0, function(){
// do something
})
dispatch_async_main(function(){
// do something
})
dispatch_sync_main(function(){
// do something
})
dispatch_async_global_queue(function(){
// do something
})
