iOS拼接json字符串的两种方式

两种json字符串拼接的⽅法如下：

+ (NSString *)UIUtilsFomateJsonWithDictionary:(NSDictionary *)dic { NSArray *keys = [dic allKeys]; NSString *string = [NSString string];

for (NSString *key in keys) {

NSString *value = [dic objectForKey:key];

value = [NSString stringWithFormat:@\"\\\"%@\\\"\

NSString *newkey = [NSString stringWithFormat:@\"\\\"%@\\\"\

if (!string.length) {

string = [NSString stringWithFormat:@\"%@:%@}\ }else {

string = [NSString stringWithFormat:@\"%@:%@,%@\ } }

string = [NSString stringWithFormat:@\"{%@\ return string;}

+ (NSString *)UIUtilsFomateJsonArrWithArray:(NSArray *)array {

NSString *string = [NSString string]; for (int j = 0; jfor (int i = 0; iNSString *value = [dic objectForKey:key];

value = [NSString stringWithFormat:@\"\\\"%@\\\"\ key = [NSString stringWithFormat:@\"\\\"%@\\\"\

if (!string.length) {

string = [NSString stringWithFormat:@\"%@:%@}\

}else if(i == 0){

string = [NSString stringWithFormat:@\"%@:%@}%@\ }else {

string = [NSString stringWithFormat:@\"%@:%@,%@\ } }

if (j != array.count-1) {

string = [NSString stringWithFormat:@\ }else {

string = [NSString stringWithFormat:@\"[{%@]\ } }

return string;} 调⽤：

第⼀种直接传⼊@\"key\":@\"value\即可，

第⼆种array⾥⾯对象需要是字典：NSArray *array = @[@{@\"key\":@\"value\
