加载plist文件中的数据，两种方法

方法－：

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

NSDictionary *drinkDictionary
= [[NSDictionary
alloc] initWithContentsOfFile:path];
NSArray *array_ = [drinkDictionary
objectForKey:@"drinks"];
NSDictionary *dic=[array_
objectAtIndex:index];
NSString *name=[dic
objectForKey:@"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_ = [[NSMutableString
alloc]
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;
[materalWebView
loadHTMLString: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 = [[NSBundle
mainBundle] pathForResource:@"DrinkInfoDataList"
ofType:@"plist"];

NSData *plistData = [NSData
dataWithContentsOfFile:path];

NSString *error; NSPropertyListFormat format;
__drinkData = [[NSPropertyListSerialization
propertyListFromData: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 = [[self
loadDinkInfoData]
count];
}

return __count;
}
- (NSString *)drinkNameAtIndex:(NSUInteger)index {

NSString *name = nil;

if (index < [self
drinkDataCount]) {

NSDictionary *data = [[self
loadDinkInfoData] objectAtIndex:index];
name = [data
valueForKey:@"name"];
}

return name;
}
- (NSArray *)drinkComponentAtIndex:(NSUInteger)index {

NSArray *_component = nil;

if (index < [self
drinkDataCount]) {

NSDictionary *data = [[self
loadDinkInfoData] objectAtIndex:index];
_component = [data
valueForKey:@"component"];
}

return _component;
}
- (NSString *)drinkMessageAtIndex:(NSUInteger)index {

NSString *message = nil;

if (index < [self
drinkDataCount]) {

NSDictionary *data = [[self
loadDinkInfoData] objectAtIndex:index];
message = [data
valueForKey:@"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 [UIImage
imageWithContentsOfFile:path];
}

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

NSString *imagename = nil;

if (index < [self
drinkDataCount]) {

NSDictionary *data = [[self
loadDinkInfoData] objectAtIndex:index];
imagename = [data
valueForKey:@"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
