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”]; NS

写入：

NSArray *paths = NSSearchPathForDirectorIEsInDomains(NSdocumentDirectory,NSUserDomainMask,YES);

Nsstring *dataPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@”sqlite.sqlite”];

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

sqlite3 *database;

if (sqlite3_open([dataPath UTF8String],&database) == sqlITE_OK){
sqlite3_stmt * complIEdStatement;
sqlite3_prepare(database,[aaa UTF8String],-1,&complIEdStatement,0);
sqlite3_bind_blob(complIEdStatement,1,[image bytes],[image length],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);
