ios - recalling and displying NSString -

-

hello im sure can answer bugging hell out of because being stupid.

i have array , can store didselectrowatindexpath row , nslog formatselected. pop view controller , desplay formatselected botton title.

- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath {     nsstring *formatselected = [[nsstring alloc]init];     formatselected:[format objectatindex:indexpath.row];     nslog(@"this format selected %@",formatselected);     [button2 settitle:[format objectatindex:indexpath.row] forstate:uicontrolstatenormal];     [navigationcontroler popviewcontrolleranimated:yes]; }

that works fine.

my problem is, in previous view newly titled button have button , label.

i want able press second button , display formatselected string in label or nslog 

-(ibaction)printresults{ nsstring *fmat = [[nsstring alloc]initwithformat:@"%@",formatselected]; nslog(@"%@",fmat);     nslog(@"nslong button pressed");}

but nslog displays (null)?

i have @property (nonatomic, retain) nsstring *formatselected; , synthesized it.

what doing wrong?

you declaring formatselected local variable in method tableview:didselectrowatindexpath:. assign formatselected within method cease accessible after method exits. assigning selected format local variable instead of property (and corresponding instance variable).

use [self setformatselected:[format objectatindex:indexpath.row]]; , remove nsstring *formatselected... line entirely.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
