從字符串變量獲取子串並保存到NSMutableArray

Question

我是iOS開發新手，面臨一些問題。我有一個像這樣的字符串M||100|??|L||150|??|S||50.我想將字符串拆分成塊並保存到數組中，e.g M 100是第一個索引，第二個索引是L 150，第三個索引是S50。

Answer 1

NSString *str = @"M||100|??|L||150|??|S||50"; 
NSString *stringWithoutBars = [str stringByReplacingOccurrencesOfString:@"||" withString:@" "]; 
NSMutableArray *array = [[NSMutableArray alloc]initWithArray:[stringWithoutBars componentsSeparatedByString:@"|??|"]]; 

Answer 2

您可以使用此代碼

NSString *str = @"M||100|??|L||150|??|S||50"; 
str = [str stringByReplacingOccurrencesOfString:@"||" withString:@" "]; 
NSArray *array = [str componentsSeparatedByString:@"|??|"]; 

這將返回您預期的結果從你的字符串數組。

Answer 3

let str = "M||100|??|L||150|??|S||50" 
let array = str.componentsSeparatedByString("|??|") 
print(array) 

結果：

["M||100", "L||150", "S||50"] 

Answer 4

///First replace "||" with " " 

NSString *your_str = @"M||100|??|L||150|??|S||50"; 
your_str = [your_str stringByReplacingOccurrencesOfString:@"||" withString:@" "]; 

///Get array of string 

NSArray *arr = [your_str componentsSeparatedByString:@"|??|"]; 
NSMutableArray *data_arr = [[NSMutableArray alloc] init]; 
for(NSString *str in arr) 
{ 
    ///string to data conversion 
    NSData *data = [your_str dataUsingEncoding:NSUTF8StringEncoding]; 

    //////// add data to array 
    [data_arr addObject: data]; 
} 
NSLog(@"data_arr =%@",data_arr); 

Answer 5

NSString *str = @"M||100|??|L||150|??|S||50"; 
NSArray *arrt = [str componentsSeparatedByString:@"|??|"]; 
NSMutableArray *arr = [[NSMutableArray alloc]init]; 
for (int i = 0; i <= arrt.count - 1; i++) { 
    [arr addObject:[[arrt objectAtIndex:i] componentsSeparatedByString:@"||"]]; 
}
