iphone - Find text in NSArray -

-

i have several custom objects in nsarray, need search through objects , fnd index of object has property matches string. should using each loop? need relatively fast search each time new character entered in textfield.

nspredicate neat, overkill (and won't give index of found object; object itself).

the paired array approach, work, feels odd me (probably because it's using paired array).

i either use for() loop (and break; when found looking for), or use block enumerator:

__block nsinteger indexofmatchingobject = nsnotfound; [myarray enumerateobjectsusingblock:^(id obj, nsuinteger idx, bool *stop) {   if ([[obj property] doeswhatimlookingfor]) {     indexofmatchingobject = idx;     *stop = yes;   } }];

or different variant:

nsinteger indexofmatchingobject = [myarray indexofobjectpassingtest:^(id obj, nsuinteger idx, bool *stop) {   return ([[obj property] doeswhatimlookingfor]); }];

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,
