PlausibleDatabase在iOS中的应用

和FMDB一样，这也是一个sqlite的objective-c的封装库，接口和FMDB一样，此外还支持sql的预编译以及参数绑定。

 

首先，需要将PlausibleDatabase.framework以及libsqlite3.0.dylib加入到项目中。

 

头文件：

 

#import <UIKit/UIKit.h>

@class PLSqliteDatabase;

@interface sqliteViewController : UIViewController {
	PLSqliteDatabase *db;
}

@property (nonatomic, retain) PLSqliteDatabase *db;

- (NSArray *)getBooks;

@end

 

实现文件：

 

#import "sqliteViewController.h"
#import <PlausibleDatabase/PlausibleDatabase.h>

@implementation sqliteViewController

@synthesize db;

- (id)init
{
	if (self = [super init]) {
		NSString *path = [[NSBundle mainBundle] pathForResource:@"CaseDatabase" ofType:@"sqlite"];
		PLSqliteDatabase *_db = [[PLSqliteDatabase alloc] initWithPath:path];
		self.db = _db;
		[_db release];
		if (![db open])
			NSLog(@"Could not open database");
	}	
	return self;
}

- (NSArray *)getBooks
{
	NSMutableArray *books = [[NSMutableArray alloc] initWithCapacity:0];
	id<PLResultSet> results = [db executeQuery:@"SELECT `ID`,`TITLE`,`COVER`,`DOCTOR` FROM `BOOKS` ORDER BY	`UPDATE_TIME` DESC"];
	while ([results next]) {
		NSDictionary *row = [[NSDictionary alloc] initWithObjectsAndKeys:
							 [NSNumber numberWithInt:[results intForColumn: @"ID"]], @"ID", 
							 [results stringForColumn:@"TITLE"], @"TITLE",  
							 [results stringForColumn:@"COVER"], @"COVER", 
							 [results stringForColumn:@"DOCTOR"], @"DOCTOR", nil];		
		[books addObject:row];
		NSLog(@"%@", books);
		[row release];
	}
	[results close];
	return books;
}

- (void)viewDidLoad {
    [super viewDidLoad];
	[self init];
	[self getBooks];
}

- (void)dealloc {
    [super dealloc];
}

@end

参数自动绑定用哪个去弄呢？
