加载plist文件中的数据，两种方法

方法－：

NSString *path = [[NSBundlemainBundle] pathForResource:@"data"ofType:@"plist"];

NSDictionary *drinkDictionary = [[NSDictionaryalloc] initWithContentsOfFile:path];

NSArray *array_ = [drinkDictionaryobjectForKey:@"drinks"];

NSDictionary *dic=[array_objectAtIndex:index];

NSString *name=[dicobjectForKey:@"name"];

        NSArray *arrayStr= [[dic objectForKey:@"material"]componentsSeparatedByString:@"\r"];//将string划分为数组，以换行的形式显示出来

NSMutableString *string_ = [[NSMutableStringalloc] initWithString:@""];

for (int i =0; i < [array_ count]; i++) {

[string_appendFormat:@"<div style='background:rgba(100, 100, 255, 0) none repeat scroll 0 0 !important;filter:Alpha(opacity=0);width:300;height:24px;'><span  style='position:relative;color:black'>%@</span></div>",[array_objectAtIndex:i]];

}

[string_appendString:@""];

materalWebView.frame =CGRectMake(20,490,280, [array_count] * 40);//UIWebView *materalWebView;

[materalWebViewloadHTMLString:string_ baseURL:nil];

方法二：

#pragma mark -loaddrinkData

-(NSArray*)loadDinkInfoData

{

   static NSArray *__drinkData =nil; // only load the imageData array once

    if (__drinkData == nil) {

       // read the filenames/sizes out of a plist in the app bundle

       NSString *path = [[NSBundlemainBundle] pathForResource:@"DrinkInfoDataList"ofType:@"plist"];

        NSData *plistData = [NSData dataWithContentsOfFile:path];

       NSString *error; NSPropertyListFormat format;

        __drinkData = [[NSPropertyListSerializationpropertyListFromData:plistData

                                                       mutabilityOption:NSPropertyListImmutable

                                                                 format:&format

                                                       errorDescription:&error]

                      retain];

        if (!__drinkData) {

           NSLog(@"Failed to read drinkData info. Error: %@", error);

            [error release];

        }

        else NSLog(@"-----drink data=%@",__drinkData);

    }

    return __drinkData;

}

- (NSUInteger)drinkDataCount {

   static NSUInteger __count =NSNotFound; // only count the data once

    if (__count == NSNotFound) {

        __count = [[selfloadDinkInfoData] count];

    }

    return __count;

}

- (NSString *)drinkNameAtIndex:(NSUInteger)index {

    NSString *name = nil;

    if (index < [self drinkDataCount]) {

        NSDictionary *data = [[self loadDinkInfoData] objectAtIndex:index];

        name = [datavalueForKey:@"name"];

    }

    return name;

}

- (NSArray *)drinkComponentAtIndex:(NSUInteger)index {

    NSArray *_component = nil;

    if (index < [self drinkDataCount]) {

        NSDictionary *data = [[self loadDinkInfoData] objectAtIndex:index];

        _component = [datavalueForKey:@"component"];

    }

    return _component;

}

- (NSString *)drinkMessageAtIndex:(NSUInteger)index {

    NSString *message = nil;

    if (index < [self drinkDataCount]) {

        NSDictionary *data = [[self loadDinkInfoData] objectAtIndex:index];

        message = [datavalueForKey:@"message"];

    }

    return message;

}

//image

- (UIImage *)imageAtIndex:(NSUInteger)index {

   // use "imageWithContentsOfFile:" instead of "imageNamed:" here to avoid caching our images

    NSString *imageName = [self imageNameAtIndex:index];

    NSString *path = [[NSBundle mainBundle] pathForResource:imageName ofType:@"jpg"];

   return [UIImageimageWithContentsOfFile:path];    

}

- (NSString *)imageNameAtIndex:(NSUInteger)index {

    NSString *imagename = nil;

    if (index < [self drinkDataCount]) {

        NSDictionary *data = [[self loadDinkInfoData] objectAtIndex:index];

        imagename = [datavalueForKey:@"imagename"];

    }

    return imagename;

}

显然第二种方法比较整齐，但有些罗嗦。。。万变不离其中
