iphone - Populate a UIImageView from a .plist -

-

i have .plist references paths .png files ( key value = "maps" ). able add images array using code while loading view: 

-(void)viewdidload  {  nsstring *path = [[nsbundle mainbundle] pathforresource:@"countries" oftype:@"plist"];   nsarray *countries = [nsarray arraywithcontentsoffile:path]; nssortdescriptor *descriptor = [[[nssortdescriptor alloc] initwithkey:@"maps" ascending:no] autorelease]; self.sortedcountries = [countries sortedarrayusingdescriptors:[nsarray arraywithobject:descriptor]];  }

i able add images tableviewcells using method: 

-(uitableviewcell *)tableview:(uitableview *)tableview     cellforrowatindexpath:(nsindexpath *)indexpath {}

what trying add these same images instance of uiimageview in new viewcontroller. have viewcontroller set properly, how can pull images array display in uiimageview did uitableviewcells?

when selecting row of table following method call-

 - (nsindexpath *)tableview:(uitableview *)tableview willselectrowatindexpath:(nsindexpath *)indexpath {      userdetailvc* userdetailvc=[[userdetailvc alloc] initwithnibname:@"userdetailvc" bundle:nil];     [userdetailvc autorelease];     //imp- set image on here         nsdictionary* tempdict=[yourarray objectatindex:indexpath.row];         userdetailvc.selectedimageview.image=[tempdict objectforkey:@"imagename"];     [self.navigationcontroller pushviewcontroller:userdetailvc animated:yes];      return nil; }

so tried this, gone you.

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,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
