ios - Objective C assigning a value to a variable -

-

i have line in header file

@property (strong, nonatomic) nsmutabledictionary *weatherdata;

and i'm truing following on implementation

-(void)dosomething {  nsmutabledictionary *data = [[nsmutabledictionary alloc] init];  //after adding items data self.weatherdata = data;  }

then have function 

-(nsmutabledictionary *)getweaterdata { nslog([self.weatherdata description]); return self.weatherdata; }

why noting gets printed, above data has data in it.

edit

self.weather data getting populated asynchronous method. take while. when i'm using nslog, wasn't populated yet. that's why nothing getting printed :d

all fixed adding delegate call back

i not believe problem rests code you've shared far. might want try adding "watch" of variable backing class property (basically, tell debugger stop execution every time code tries update value property).

if want this, can:

  1. add breakpoint in code before set property first time;

  2. run app in debugger stops @ breakpoint;

  3. add watch on variable control clicking on variable in "variables view" in "debug area" in xcode (in case, i'd adding watch on objects property):

    enter image description here

  4. continue execution of program hitting "continue" button (continue)).

the app stop app every time property changes, can inspect line of code changing value , examine other associated variables. if debugger stops @ cryptic assembler code, click on "step out" button (step out) until see of own code recognize.

perhaps "watching" can identify setting and/or resetting value of weatherdata in app.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

java - What is the difference between String. and String.this. ? -

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
