ios - When I use AsyncUdpSocket object to send IP packet, It is not always working -


i using cocoaasyncsocket. got there. asyncudpsocket object me send ip packet when init object. when use [engineobject startsession] call function in other controller, function working, asyncudpsocket object won't send ip packet out. won't call (or trigger) delegate method: didsenddatawithtag or didnotsenddatawithtag.....

what did wrong?

.h 

#import <foundation/foundation.h> #import "asyncudpsocket.h"  @interface engine : nsobject{     asyncudpsocket *asyncudpsocket; } @property (atomic, strong) asyncudpsocket *asyncudpsocket; - (id) init; - (bool) startsession; - (void) dosomething; @end

.m

@implementation engine  - (id) init {     [self dosomething];  //<-----<< can send ip packet out      self = [super init];      [self dosomething];  //<-----<< can send ip packet out, wrong bind source port     if (self){      }     return self; }  - (bool) startsession{     [self dosomething]; //<-----<< won't send ip packet out      [self oxox];     return yes; }  - (void) oxox{      [self dosomething]; //<-----<< won't send ip packet out   }  - (void) dosomething{     nserror *socketerror=nil;     asyncudpsocket = [[asyncudpsocket alloc] initwithdelegate:self];     if (![asyncudpsocket bindtoport:7701                               error:&socketerror]){         nslog(@"rasengine:    bind port fail");     }     [asyncudpsocket enablebroadcast:no error:&socketerror];     uint8_t signalbytes[] = {0x07, 0x07, 0x01, 0x06, 0x12, 0x34, 0x56, 0x78};     nsdata *signaldata = [nsdata datawithbytes:signalbytes length:8];      [asyncudpsocket senddata:signaldata   //<--------<< called every time, doesn't send out.                         tohost:@"192.168.16.18"                         port:9902                  withtimeout:-1                          tag:0]; }  #pragma mark - #pragma mark asyncudpsocket delegate udp - (void)onudpsocket:(asyncudpsocket *)sock didsenddatawithtag:(long)tag{     nslog(@"udp engine:    onudpsocket:didsenddatawithtag:%ld", tag);    }   - (void)onudpsocket:(asyncudpsocket *)sock didnotsenddatawithtag:(long)tag duetoerror:(nserror *)error{     nslog(@"udp engine:    onudpsocket:didnotsenddatawithtag:%ld", tag);     }  @end

after 1 week fight, found problem caused runloop. using gcdasyncudpstoket replace asynvudpsocket, problem solved! 

gcdasyncudpsocket *gcdasyncudpsocket = [[gcdasyncudpsocket alloc] initwithdelegate:self                                                                      delegatequeue:dispatch_get_main_queue()];

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!

i have buttona , when buttona clicked, want keyboard show uitextfield in inputaccessoryview. there way have keyboard show manually , set inputaccessoryview without having uitextfield initially? thanks. you cannot summon keyboard without object can become first responder. there 2 ways work around: subclass uiview , implement uikeyinput protocol in it. example: in .h file: @interface inputobject : uiview<uikeyinput> @property (nonatomic, copy) nsstring *text; @property (nonatomic, strong) uiview *inputaccessoryview; // must override inputaccessoryview , since it's readonly default @end in .m file, implement protocol: - (bool)canbecomefirstresponder { return yes; } - (bool)hastext { return [self.text length]; } - (void)inserttext:(nsstring *)text { nsstring *selftext = self.text ? self.text : @""; self.text = [selftext stringbyappendingstring:text]; [[nsnotificationcenter defaultcenter] postnotificationname:kinputobjec...
