ios - Passing property to another view -

i have problem prepareforsegue method. need pass nsstring 1 view is:

2013-08-13 12:13:45.765 dailyphotos[12551:907] -[archiveviewcontroller textlabel]: unrecognized selector sent instance 0x1e5592f0 2013-08-13 12:13:45.775 dailyphotos[12551:907] *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[archiveviewcontroller textlabel]: unrecognized selector sent instance 0x1e5592f0' *** first throw call stack: (0x328852a3 0x3a52a97f 0x32888e07 0x32887531 0x327def68 0x813dd 0x34a1ade9 0x8174d 0x3474f28d 0x347d1f81 0x33193277 0x3285a5df 0x3285a291 0x32858f01 0x327cbebd 0x327cbd49 0x3638f2eb 0x346e1301 0x78fb9 0x3a961b20) libc++abi.dylib: terminate called throwing exception 

here prepareforsegue implementation:

- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {     // checking segue perform     if ([[segue identifier] isequaltostring:@"projectdetailssegue"]) {         albumviewcontroller *destinationview = [segue destinationviewcontroller];         // creating variable selected cell         uitableviewcell *selectedcell = (uitableviewcell *)sender;         //  passing cell title destination cell         destinationview.projecttitle = @"tmp";         nslog(@"%@", selectedcell.textlabel.text);     } } 

for i'm passing @"tmp" , works when try pass connected selectedcell crashes. why happening? how can reapir problem?

you using sender selectedcell.

but can see in error, sender not uitableviewcell, archiveviewcontroller. because doing a:

[self performseguewithidentifier:@"projectdetailssegue" sender:self];

what should doing is:

[self performseguewithidentifier:@"projectdetailssegue" sender:*yourcell*];
