Iphone SDK UITextView text length -

-

how can know text out of fit (that text need scrolled)? have methods or this?

thanks.

use nsstring uikit additions. allow calculate height of string given size , font. can calculate height in way:

 cgfloat textviewwidth = cgrectgetwidth(textview.bounds); cgsize inset = cgsizemake(5.0,5.0); cgsize stringsize = [mystring sizewithfont:textview.font constrainedtosize:cgsizemake(textviewwidth-2*inset.width,1024) linebreakmode:uilinebreakmodewordwrap]; bool textoutoffit = stringsize.height+2*inset.height>cgrectgetheight(textview.bounds);

note code requires fine tuning. infact text inside text views has internal margin (that took account using inset structure), required text view height higher calculated string height. code ask nsstring calculate size when horizontally constrained in textview boundaries (while 1024 in height maximum uiview height possible). check if returned string height inside or not text view boundaries.

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,
