往sqlite中写入图片二进制数据及读取源码 for iphone

概述写入: NSArray *paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES); NSString *dataPath = [[paths objectAtIndex:0]stringByAppendingPathComponent:@”sqlite.sqlite”]; NSDat

写入:

NSArray *paths =NSSearchPathForDirectoriesInDomains(NSdocumentDirectory,NSUserDomainMask,YES);
Nsstring *dataPath = [[paths objectAtIndex:0]stringByAppendingPathComponent:@”sqlite.sqlite”];

NSData*image=UIImagePNGRepresentation([UIImageimagenamed:@"01_02.png"]);
Nsstring *aaa=[[Nsstring alloc]initWithFormat:@”update cards setc_image=? where ID=1″];

sqlite3 *database;

if (sqlite3_open([dataPathUTF8String],&database) == sqlITE_OK){
sqlite3_stmt * complIEdStatement;
sqlite3_prepare(database,[aaaUTF8String],-1,&complIEdStatement,0);
sqlite3_bind_blob(complIEdStatement,1,[image bytes],[imagelength],NulL);
int result=sqlite3_step(complIEdStatement);
if (result==sqlITE_DONE) {
}
sqlite3_finalize(complIEdStatement);

}
sqlite3_close(database);
[aaa release];

读取:

}
else{

} } } sqlite3_finalize(complIEdStatement); } sqlite3_close(database);
