我有一个NSMutableArray,其中包含我需要转换为NSString的数据。
data = [NSMutableArray array];
Content string to write out to text file.
NSString *content = [NSString stringWithFormat:@" Log \nDevice Id Number: %@ \n=====Data received from device %@====\n Moves: Miles: \n \n \n \n====Data sent to Portal %@====\n Moves: Miles: \n \n \n \n====Data received to %@====\n Response \n\n ",serialNumber, dateString, dateString, dateString];
[self setStatus:@"Syncing data..."];
self.userInfo = [self.cloud Authenticate:[self serialNumber]];
if ( self.deviceInfo )
{
data = [self.device GetData:&error];
if ( !data )
{
[self displayErrorMessage:error];
data = [NSMutableArray array];
}
// Getting sync data
NSString *path = [@"~" stringByExpandingTildeInPath] ;
path=[path stringByAppendingString:@"/Documents/Movband Reports/"];
NSString *fileName = [NSString stringWithFormat:@"%@/movbandData.txt",path];
NSString *content=[data componentsJoinedByString:@"-"]; // Sync data
答案 0 :(得分:2)
如果您的数据(数组)有字符串,并希望通过某些字符/字符串使用
来附加它NSString *content=[data componentsJoinedByString:@"-"];
或者,您可以遍历data
并继续添加某些条件(您知道哪个索引具有什么值)
NSMutableString *content=[NSMutableString new];
for(NSInteger i=0; i<data.count; i++){
switch(i){
case 0:[content appendString:@"Device Id Number: %@"];
break;
case 1:[content appendString:@"=====Data received from device %@"];
break;
case 2:[content appendString:@"Moves: Miles: \n \n \n \n====Data sent to Portal"];
break;
case 3:[content appendString:@" Moves: Miles: \n \n \n \n====Data received to %@"];
break;
}
[content appendString:data[i];
}
