我要评论一、afnetworking post字符串
修改位置afurlrequestserialization
修改前
nsstring * afquerystringfromparameters(nsdictionary *parameters) {
nsmutablearray *mutablepairs = [nsmutablearray array];
for (afquerystringpair *pair in afquerystringpairsfromdictionary(parameters)) {
[mutablepairs addobject:[pair urlencodedstringvalue]];
}
return [mutablepairs componentsjoinedbystring:@"&"];
}
修改后
nsstring * afquerystringfromparameters(nsdictionary *parameters) {
if ([parameters iskindofclass:[nsstring class]])
return (nsstring *)parameters;
nsmutablearray *mutablepairs = [nsmutablearray array];
for (afquerystringpair *pair in afquerystringpairsfromdictionary(parameters)) {
[mutablepairs addobject:[pair urlencodedstringvalue]];
}
return [mutablepairs componentsjoinedbystring:@"&"];
}
二、查找一个字符串中的多个相同子字符串
nsstring *str = @"14 28 62 24 3 46 99 73 10 51 0 95 34 58 50 33 56 23 97 82 83 8 94 1 17 7 19 96 9 54";
nsstring *searchstring = @"1";
nsrange searchrange = nsmakerange(0, [str length]);
nsrange range;
while ((range = [str rangeofstring:searchstring options:0 range:searchrange]).location != nsnotfound)
{
nslog(@"%@",nsstringfromrange(range));
searchrange = nsmakerange(nsmaxrange(range), [str length] - nsmaxrange(range));
}
