iphone - UDP communication with some interface (using UDP Echo sample code, problem with main.m) -

-

i´ve downloaded udpecho sample code apple make simple udp "connection" device.. i´m able make "connection" setting ip , port of device on main.m provided. analyzing console i´m getting positive response device i´m sending main.m.

my problem main.m doesn´t load .xib. have tried modify , put uiapplicationmain (argc,argv,nil,nil) , stuff, in case got default .xib (with prjctviewcontroller ) load don´t response on console. in case there no udp connection @ all.

how can use udpecho sample set simple udp "connection" user interface? simple user being able enter ip , port , getting response device shown in screen. communication not problem, i´m getting responses in console, whole problem setting simple interface while using sample code. don´t know how can "override" main.m load .xib while maintaining connection. i´ve tried pass functions main.m prjctviewcontroller doesn´t seem solve problem. if has example show me or ideas enlighten me i´ll thankfull.

start connection stuff in 1 of app launch, view controller init, or button event delegates. handle connection asynchronously, or in background thread, not block ui thread.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
