越狱后的手机的数据库文件可以自由访问,通话记录通常保存在call_History.db这个文件中.只要读取这个文件,我们就能知道目前手机的通话记录了
下面这段代码检测手机是否能读取到Call_History.db
NSFileManager *fileManager = [NSFileManager defaultManager];
NSDirectoryEnumerator *dirnum = [[NSFileManager defaultManager] enumeratorAtPath: @"/private/"];
NSString *nextItem = [NSString string];
while( (nextItem = [dirnum nextObject])) {
if ([[nextItem pathExtension] isEqualToString: @"db"] ||
[[nextItem pathExtension] isEqualToString: @"sqlitedb"]) {
if ([fileManager isReadableFileAtPath:nextItem]) {
NSLog(@"%@", nextItem);
}
}
}
通常发现的文件位置为var/wireless/Library/CallHistory/call_history.db,ios3和4可能不同,具体看上面代码打印的结果.
下面这段代码可以读出数据库中的内容,具体怎样显示自己定制把.
- (void)readCallLogs
{
if (_dataArray == nil) {
_dataArray = [[NSMutableArray alloc] init];
}
[_dataArray removeAllObjects];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *callHisoryDatabasePath = @"var/wireless/Library/CallHistory/call_history.db";
BOOL callHistoryFileExist = FALSE;
callHistoryFileExist = [fileManager fileExistsAtPath:callHisoryDatabasePath];
[fileManager release];
//NSMutableArray *callHistory = [[NSMutableArray alloc] init];
if(callHistoryFileExist) {
if ([fileManager isReadableFileAtPath:callHisoryDatabasePath]) {
sqlite3 *database;
if(sqlite3_open([callHisoryDatabasePath UTF8String], &database) == SQLITE_OK) {
sqlite3_stmt *compiledStatement;
NSString *sqlStatement = [NSString stringWithString:@"SELECT * FROM call;"];
int errorCode = sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1,
&compiledStatement, NULL);
if( errorCode == SQLITE_OK) {
int count = 1;
while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
// Read the data from the result row
NSMutableDictionary *callHistoryItem = [[NSMutableDictionary alloc] init];
int numberOfColumns = sqlite3_column_count(compiledStatement);
NSString *data;
NSString *columnName;
for (int i = 0; i < numberOfColumns; i++) {
columnName = [[NSString alloc] initWithUTF8String:
(char *)sqlite3_column_name(compiledStatement, i)];
data = [[NSString alloc] initWithUTF8String:
(char *)sqlite3_column_text(compiledStatement, i)];
}
[callHistoryItem setObject:data forKey:columnName];
[columnName release];
[data release];
}
[_dataArray addObject:callHistoryItem];
[callHistoryItem release];
count++;
}
}
else {
NSLog(@"Failed to retrieve table");
NSLog(@"Error Code: %d", errorCode);
}
sqlite3_finalize(compiledStatement);
}
}
}
NSLog(@"%@",_dataArray);
}
到此,你就可以读出所有的通话记录了.
