Question

这是我的NSMutableArray。它包含位置15的空格。当我将其存储在另一个NSMutableArray中时，它会给出一个空值。

如何在该特定位置删除阵列中的这个空间？

Answer 1

试试这可能会对你有所帮助

NSCharacterSet *charsToTrim = [NSCharacterSet characterSetWithCharactersInString:@"()  \n\""];
s = [s stringByTrimmingCharactersInSet:charsToTrim];

Answer 2

试试这个

NSString *str=[arrMessage objectAtIndex:index];
str=[str stringByReplacingOccurrencesOfString:@"Srvice Title" withString:@"SrviceTitle"];

Answer 3

    NSString *string=[yourArray objectAtIndex:15];

    NSCharacterSet *charsToTrim = [NSCharacterSet whitespaceAndNewlineCharacterSet];

    NSString *newString = [string stringByTrimmingCharactersInSet:charsToTrim];

    [yourArray replaceObjectAtIndex:15 withObject:newString];

Answer 4

customerDetails=[customerDetails1 stringByReplacingOccurrencesOfString:@"\n" withString:@""];

此处customerDetails1将数组转换为字符串。

customerDetails是存储结果字符串的另一个字符串。这对我有用。

Answer 5

试试这个，

NSMutableArray *array = [[NSMutableArray alloc] init];
[yourArray enumerateObjectsUsingBlock:^(NSString *element, NSUInteger idx, BOOL *stop) {
    element = [element stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
    [array addObject:element];
}];
