make variable in app delegate , synthesize this

in appdelegate.h

@interface appdelegate : nsobject <uiapplicationdelegate> {     uiimage *myimage; }  @property (nonatomic, retain) uiimage *myimage;

in appdelegate.m

@implementation appdelegate  @synthesize myimage;

then create appdelegate instance in view controller in addprileviewcontroller.m

-(void) imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info {      [picker dismissviewcontrolleranimated:yes completion:nil];     uiimage * pickedimage = [info objectforkey:uiimagepickercontrolleroriginalimage];     addprofileviewcontroller * controller = [addprofileviewcontroller new];     controller.imageview.image = pickedimage;     appdelegate *appdel=(appdelegate *)[uiapplication sharedapplication].delegate;      appdelegate.myimage=pickedimage; }

now selected image stored in myimage variable , can use anywhere want

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> ...

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...
