iOS - copy all NSMutableAttributedString attributes to another NSMutableAttributedString -


i'd copy attributes 1 nsmutableattributedstring new one. code i've tried this:

[attrstr enumerateattribute:nsfontattributename inrange:nsmakerange(0, attrstr.length) options:0 usingblock:^(id value, nsrange range, bool *stop) {         if (value) {            // uifont *oldfont = (uifont *)value;             uifont *newfont = [_label.attributedtext             [attrstr removeattribute:nsfontattributename range:range];             [attrstr addattribute:nsfontattributename value:newfont range:range];             //found = yes;         }     }];

the code incomplete , looks attempting fonts only. i'd loop through every attribute , add new nsmutableattributedstring variable. update: question how apply attributes of 1 nsmutableattributedstring nsmutableattributedstring ? can use method somehow:attribute:atindex:effectiverange

nsmutableattributedstring (and nsattributedstring) conforms nscopying. should able this:

nsmutableattributedstring *mutablecopy = attrstr.mutablecopy; nsattributedstring *immutablecopy = attrstr.copy;

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
